Shimamura, Arthur P. (2008). A neurocognitive approach to metacognitive monitoring and control

Shimamura, Arthur P. (2008). A neurocognitive approach to metacognitive monitoring and control. In J. Dunlosky & R. A. Bjork (Eds.), Handbook of metamemory and memory (pp. 373-390). New York: Psychology Press.

After I read the paper of Nelson and Narens, I came across the paper where Shimamura added the brain components to Nelson and Narens' model of metacognition and addressed the notions in the dynamic filtering theory.



Since I know for sure that the my brain is wired pretty wrong and in different ways, it's pretty cool to read up this paper and say... "Yes! Yes! Yes! I've gotta have problems there, too!"  Sort of reminding me of the experiences I (and some of my classmates) had when taking abnormal psychology for the first time in undergrad.  It seemed like all diagnosis in the neurosis department were applicable to me though I had such difficulties differentiating between delusions and hallucinations.  (Speaking of ignorance is a bless. lol 8-X)

As is shown in the figure above, neurobehavioral research has found the critical role of prefrontal cortex (PFC) on the top-down control of information processing (e.g., Fernandez-Duque, Baird, & Posner, 2000; E. K. Miller & Cohen, 2001; Shimamura, 2002a; Smith & Jonides, 1999).  Theorists have also worked on mapping out the metacognitive functions of PFC regions (Fernandez-Duque et al., 2000; Pannu & Kaszniak, 2005; Shimamura, 1996; Stuss, Gallup, & Alexander, 2001).

Dynamic filtering theory:  So, first of all, PFC is well connected with many cortical regions.  It was proposed that the well-connected PFC regulates the activation of the posterior cortex by way of a filtering/gating mechanism.  So, in this theory, the meta-level processors in the PFC control those at the object level in the posterior cortex.  How does PFC assert its control?  It's done through dynamic filtering... "the selection of appropriate signals and suppression of inappropriate signals."

The author considered the inhibitory control to be of particular importance because due to the inevitable interference among object-level processors.  When conflicts or interference are observed at the object-level, the meta-level has to make a decision on which process(es) to suppress and which to continue. In the author's own words, "Based on dynamic filtering theory, it is the interplay between PFC and posterior regions that implements both selective and suppressive control."

Also, because different regions of the PFC seems to be in charge of different things (though there might be overlaps in their functions), the way it sound... metacognition in the brain works almost like cloud/distributed computing.  8-O lol  At the end of this paper, the author did ask the question of whether there might be a CEO for the various PFC regions... sort of like... with the anterior PFC (BA10) offered as the plausible candidate.


This paper is also loaded with interesting notions and information; however, I will share with you the thoughts I have rather than providing a summary of the key ideas in this paper.

Monitoring and controlling stimulus encoding

One question that's been troubling me is whether metacognition can assert its impact at as early as the stage of sensory memory.   Why?  As a psychotic, it would be wonderful if hallucinations can get filter out before even entering the working memory so as to prevent the hallucinations from being incorporated in my delusional world (of course, the assumptions: hallucinations are first perceived in the sensory memory and the information processing model holds true).  Nothing intellectual... pure practical.

Though I feel sorry for patients with brain lesions, what the authors addressed in this section gives me hope...  "It is as if PFC lesions disrupt cortical processing in the posterior cortex by failing to gate or filter activations."

Though... questions... the plain old selection mechanism between Sensory memory and Working memory could be considered as metacognitive? 8-O (Interesting... Never thought of it this way... though no answer to it.)

Monitoring and controlling learning process

Notions under this title seem to be related to the functioning of working memory.

While studies have confirmed the role of PFC in the maintenance and manipulation of information in working memory, different prefrontal regions seem to maintain different kinds of information.

There is something interesting about the quote that "successful learning depends on a host of metacognitive control processes, including selection, maintenance, updating, and chunking."  When I first read this quote, so I thought... aren't these ordinary things at the cognitive or object-level?  Then I thought of the cross-sectional studies conducted on young children... how they need to be taught metacognitive strategies to help themselves learn... For instance, perhaps, not random selection or selecting for the purpose of selecting, but... strategic selection...

The discussion on proactive interference  are also very interesting.  Essentially, participants were given stimuli and were asked to determine if a stimuli had been shown to them before.  One group was given cues on whether they should attend to face or scene while the other group not.  It was found that the posterior cortical regions exhibited heightened activities on trials with task-relevant stimuli and reduced activities when task-irrelevant.  At the same time, previous studies have found the selective attention to be modulated by PFC.

Why do I find this discussion interesting?  It's like--you need to give yourself this cue about your observations in life--delusion or not?  If delusional, don't get your head too excited since it is irrelevant.  8-O

Monitoring and controlling retrieval processes

"[V]entrolateral PFC activity increases with increases in the number of competing responses (Wagner et al., 2001). Such regulation of semantic retrieval extends to other linguistic tasks, such as making decisions about the conceptual relatedness between items or interpreting difficult or ambiguous sentences (see Wagner
et al., 2001)."--Feels like it has something to do with delusion of references?


A Multilevel Model of Dynamic Filtering Theory and Extension of the Nelson and Narens Metacognitive Model

How I am wrong...

Biased to the processing of internal stimuli (hallucinations, delusions) and self-related contents

  1. The ventrolateral PFC is integral in selecting semantic information and maintaining that information in working memory (Wagner et al., 2001; Thompson-Schill et al., 2002). 
  2. The dorsomedial PFC (e.g., anterior cingulate cortex) is involved in monitoring cognitive conflict in object-level processors (Botvinick et al., 1999, 2004).

The failure to negate the "biased" information (e.g., delusions) after detection

  1. The dorsolateral PFC facilitates the manipulation of information in working memory by updating and rerouting information processing (Shimamura, 2000; Simons & Spiers, 2003).

One faulty department that might have been the trigger for all my hospitalization with its impact even stronger towards hospitalization... ventromedial PFC... because... kaput ventromedial PFC--> Excessive motional arousal-->tying up the brain capacity-->interfering with the function of other PFC regions-->bye bye the monitoring and control of psychotic symptoms-->into the Club Meds I go.

  1. [T]he ventromedial PFC enables the same kind of monitoring and control as other PFC regions, only it regulates affective processes rather than cognitive processes.

The feeling of knowing is also addressed in this paper... intuitively I would say... there is something about FOK... whether you believe it or not...

Nelson & Narens (1990). Metamemory: A theoretical framework and some new findings.

Nelson, T.O. & Narens, L. (1990). Metamemory: A theoretical framework and some new findings. In G.H. Bower (Ed). The Psychology of Learning and Motivation, 26, 125-173. New York: Academic Press

A: The abstract principles of metacognition

(The following three principles are the exact quotes)
  1. Principle 1: The cognitive processes are split into two or more specifically interrelated levels: the meta-level and the object-level.
  2. Principle 2: The meta-level contains a dynamic model of the object-level.
  3. Principle 3: There are two dominance relations, called "control" and "monitoring," which are defined in terms of the direction of the flow of information between the meta-level and the object-level. This distinction in the direction of flow of information is analogous to that in a telephone handset.
This diagram in Nelson and Narens (1990) (p. 126) shows the theoretical mechanism consisting of the meta-level and the object-level and their relations.  
This diagram above shows a theoretical mechanism consisting of the meta-level (e.g., metacognition) and the object-level (e.g., cognition).

The authors used the telephone handset analogy to explain the information flow between the meta and the object levels.  The way I interpret it is... its' sort of like the relations between Gordon Ramsey and the chefs in Hell's Kitchen (if not simply the chefs and their dishes)... with what goes on in your head the equivalent of "Hells Kitechen." (At least mine).  (Could cook something up with my psychosis though might as well go directly with cooking...)




The role of Gordon Ramsey is equivalent to your metacognition and the role of the chefs, cognition.  What the chefs cook up are like the cognitive outcome and how they do the cooking, the cognitive processes.  As the chefs are busy cooking down there, Ramsey (meta-level) gets information about what is going on with the chefs (object-level)--this is the monitoring process.  After Ramsey (meta-level) processes the information he gathers, he (metal-level) goes on yelling at these chefs (object-level) and tells them (object-level) what to do, and the chefs go back on to cook following the directions of Ramsey... this is what the control relation is about.

It might be an even better analogies if there are multiple people with a role similar to that of Gordon Ramsey... since some theories believe that how metacognition works in the brain is more or less like the notion of cloud computing... different regions associated with different metacognitive roles.

Also, one thing I kept on hearing Ramsey yelled out loud was... "Out! Out! Out!" Well, maybe your metacognition doesn't do it... mine surely does it on a daily basis... 

1. Control

The notion behind control is that the meta-level modifies the object-level... its state or process... and contribute to actions at the object-level: 1. to initiate and action, 2. to continue an action, or 3. to terminate an action.

2. Monitoring

The basic notion behind monitoring is that the meta-level is informed by the object-level... and result in the change in the model the meta-level has on the situation, including "no change" (i.e., Gorgon Ramsey's view of how the kitchen is running).  

Interestingly, as per Nelson and Naren (1990), "the opposite does not occur, i.e., the object-level has no model of the meta-level."  Don't think I really understand it... and thus... don't have the audacity to agree or disagree... Yet, in the process of working on the psychotic model of how my psychotic mind works... including at the metacognitive level, aim I not building up a cognitive model (object-level) of my metacognition (meta-level)? 8-O

Donno, maybe I haven't quite gotta the notion the authors were trying to convey or my example might be buggy and I am too blind to see it.

3.  Role of subjective reports about introspection for inferences about monitoring

Following are some notions the authors mentioned about the methodological issues they encountered.
  1. The measurement issue on introspective reports--the assumption behind using telescopes to observe and that when studying the use of telescopes as an instrument.  Were my head the equivalent of a telescope, I have no doubt doubting the validity of its outputs and distortions.  lol
  2. Views on introspective reports: descriptions of internal processes (as per the Structuralist's view) vs. data to be explained.  
  3. "A system that monitors itself (even imperfectly) may use its own introspections as input to alter the system's behavior."  I am in total agreement with this notion... the basic assumption of monitoring our psychotic mind with our disordered thinking.
  4. Perception could be conceptualized as sensation plus inference... the coexistence of accuracy and distortion--true value and error.  Apparently, even the normal have to deal with the error term...

B. The monitoring and control of human memory

This diagram in Nelson and Narens (1990) (p. 129) shows examples of monitoring and control tasks at different stages of learning.
The way I see it... correct or not... what's between monitoring and control is the processes occurring at the cognitive or object level... for the perspective of information processing theory... the middle section looks almost like the working memory (WM).  When discussing the theoretical framework represented by the above model, the authors recommended the context of student studying for an exam to the readers. 

Among all, one thing that differentiates between the model of Flavell (1979) and this one (Nelson & Narens, 1990) is that Nelson and Narens broke it down further... the processes at the meta-level and object-level (e.g., WM) and subdivided monitoring into ease of learning, judgments of knowing and feeling of knowing.

Most of the things the authors discussed are captured in the above diagram.  In the following section, I will only mention the notions of interest to me.  

1. Acquisition stage: In advance of learning

a. Determining one's goal: the person's norm of study

  1. A person's theory of retention is used to modulate how well the content has to be mastered in order for it to be remembered and recalled in the retention tasks.
  2. The norm of study is the product of an individual's theory of retention... the mastery the individual believes he or she should obtained during the acquisition phase.

b. Formulating a plan to attain the norm of study

Retrospective monitory vs. Protrospective monitoring in the context of seeing airplanes in the sky:
  • Retrospective monitoring (judgments of past performance): How well did I do the last time I saw an airplane flying in the sky?
  • Protrospective monitoring (judgments about subsequent performance): How well might I fare the next time I see an airplane flying in the sky?
The authors further subdivided protrospective monitoring into three categories:
  1. 1. Ease-of-learning (EOL): occurring in advance of acquisition.
  2. 2. Judgments of learning (JOL): occurring during or after acquisition to predict future performance on currently recallable items
  3. 3. Feeling of knowing (FOK): occuring during or after acquisition about whether a currently nonrecallable item is known and/or will be remembered in a subsequent test
Research found that EOL, JOL, and FOK are not highly correlated... meaning they measure different things... or these judgments might measure different aspects of memory with the structure underlying these judgments multidimensional.  

c. Ease of learning judgments.

The outcome of EOL can affect the amount of time allocated to study.

d. A Prior Choice of Processing judgments

After EOL, the person decides the kinds of processing to use on the study item.

e. Initial plan for the allocation of study time

Monitoring: this is a harder item to learn=>control: allocate more time
This diagram in Nelson and Narens (1990) (p. 132)
This is the diagram of my dream... since there's nothing new under the sun... I know I can found someone who has already gotten a model like this out... the separation of cognition and metacognition.  In this diagram, the upper portion (theoretical) represents metacognition while the lower portion, the processing in the working memory or cognitive level.

2. Acquisition stage: the ongoing learner


Following is the flowchart showing how learning works... at the metacognitive level and it's relation with the cognitive level.  One thing I love most that table titled metacognitive library, which, according to Flavell (1979) is rightfully encoded in LTM.  Why is this notion important? What is the likelihood that a certain strategy will be effective in intervening  a certain type of psychotic scenario?

This diagram in Nelson and Narens (1990) (p. 133)

Some processing involved in the above cycle...

a. Feeling of knowing for currently nonrecallable items.
FOK is linked to time allocation
b. Judgments of learning for currently recallable items:
Are you making judgments of future performance based on monitoring of information in the WM or long term memory?  Delayed recall might resolve this issue.
c. Updating the allocation of study time during a particular study trial of an item.
People study till the JOL for the item reach the norm of study though their judgments might be really off from the reality. Motivation might be a confounding factor.
d. Termination of study.
When JOL reaches the norm of study, study is terminated.

3. Retention stage

The maintenance of previously acquired knowledge might involve similar process as in the acquisition stage with the following additions:
  1. 1. discrepancy between the desired degree of mastery and the assessed degree of mastery
  2. 2. FOK-directed maintenance work

4. Retrieval stage: Termination

The distinction between self-directed and non-self-directed retrieval... Nelson and Narens focused on self-directed retrieval: the search itself and setting up the cues to initiate the search.  The following is the flowchart for the retrieval stage.

This diagram in Nelson and Narens (1990) (p. 136)

a. Quick initiation/termination of retrieval.

Possibly FOK-based with a latency far shorter than that for an actual recall. 
There is something very interesting about the notion of quick initiation and FOK... like... I know that feeling... can't give you the exact reason why but I think it's delusional... The FOK arrives before the identification.

b. Placement of retrieval termination:

The termination happens when someone is no longer willing to continue of the FOK no longer exceed the threshold of claiming to know the non-retrieved items. 

The good thing about my lack of creativity is that I seemed to have oversaturated the kinds of delusions my head is capable of creating... thus, not too many records for the head to search through when trying to answer the question of whether the observed event fit the profile of past delusions or not.  Given the limited number of search my head has to perform, and, I suspect, more sophisticated search algorithm it operates on as a result of being a more experienced psychotic (than in my younger years) plus my false-positive-allowed policy, there's gotta be an extremely high threshold for nonretrieved items.  Also, in the context of psychosis, premature termination might be something really risky... untreated delusions etc can become the weakest link my my head's security.

5. Retrieval Stage: Output of response.

People's threshold for outputting the retrieved answer might be affected by factors such as "cost vs. rewards.

6 Retrieval stage: Confidence judgments after recall

Commission error vs. omission error


After the description of the model, the authors went on discussion some issues concerning the methodology and relevant findings for their research.  Since my main interest is in the model itself, I will only mention the points of relevance to me.

1. Amount of information deposited in long-term memory is important for metacognitive monitoring. (That's why I went back to the psychiatric ward during the second full-blown episode.

a. Our early experiment
The FOK results
  1. Reliability: People are consistent in their FOK judgments
  2. Validity: The consistent judgments of people are not all that useful in predicting the outcome of future performance
b. Effect of degree of learning on retention interval on FOK accuracy
In order to perform monitoring, you need to have enough beef registered in the LTM.
With the retention rate, it looks like you have to lit it sit for some time to get the correct accessment.

c. Our first published experiment on metamemory
The degree of learning is important to FOK accuracy.  (Nelson, Leonesio, Shimamura, Landwehr & Narens, 1982)

d. Mechanisms for the overlearning effects on metacognitive accuracy:
  1. Metacognitive judgments attempt to discriminate between items.  Higher accuracy in discriminating items when the differences between the items increase
  2. Overlearning might enhance the stability of retention and increase the differences between items.
e. Empirical support for the item-discrimination mechanism
People are reasonably fine as measuring devices but their have limits in their ability to differentiate between objects.  The more different the item, the more likely for the metacognitive discrimination to be valid. Whether items could be validly discriminated is dependent on the person's ability to monitor and the degree of differences between items (difficulty level).


2. FOK may be perfectly valid at tapping a larger number of aspects of LTM but the accuracy of FOK for predicting criterion performance may nevertheless be imperfect.

This is an interesting one... in the context of psychosis, there is this FOK... the sense that the observation is delusional.  In reality, I treat all observations with uncertain intents as delusional--false positive allowed. For practical purposes, it doesn't have to be perfect... as long as no false negative.

FOK dependent on what's in LTM rather than in WM or unconscious memory.

3. Privileged access


a. Judge/observer experiments
People's prediction might benefit from the idiosyncratic information at their disposal during retrieval.
b. Normative predictions vs. the individual's own FOK prediction.
People's FOK predictions on their own subsequent performance on currently nonrecallable items  is better than the normative FOK prediction derived from the average prediction.  But individual's FOK predictions are worse than predictions derived from the normative probability of correct recall.  It has been found that the accuracy of people's FOK prediction is higher when given the normative probability of recall...Unfortunately, people seems to be poor at intuiting the normative probability of recall on items that can not recall.

4. Some factors underlying people's FOK judgments (vs. accuracy)

a. Overlearning affects not only FOK accuracy but als the magnitude of FOK.
b. Overlearning study trials vs. overlearning test trials.
Both the study trials and test trials affect the magnitude of subsequent FOK.
c. Actual overlearning vs. claimed overlearning.
Most effects of overlearning on FOK seemed to be mediated by people's belief about whether the items have been overlearned... as opposed to an "automatic" effect of overlearning.
The no-Magic Hypothesis for how FOK should be conceptualized: the person 1). considers particular recallable properties of the to-be-retrieved items) in conjunction with 2). rules about how the properties are related to the subsequent criterion performance that the person is trying to predict.

According to non-magic hypothesis, "FOK does not directly monitor a given unrecalled item in memory, but rather the FOK monitors recallable aspects related to that item, such as the item's acquisition history or partial/related recalled components."

5. Learning-to-learn effect for FOK judgment?

Can FOK accuracy be improved by sheer practice on FOK judgments? It doesn't matter whether you provide feedback or not on their FOK judgments... the practice effect is small shall it ever occur.

6. Relation between metacognitive monitoring and metacognitive control during acquisition: The allocation of self-paced study time.

The allocation of study time is also mediated by people's EOL and FOK in addition to a response to item difficulty.
If people believe that they have learned things well, it's useless to give them more time to learn.


7. Relation between metacognitive monitoring and metacognitive control during retrieval: termination of memory searching.


a. Role of "preliminary FOK judgments" prior to searching for an answer.
  1. Single-counter FOK hypothesis: one FOK component that only taps the presence of information in memory
  2. Dual-counter FOK hypothesis: tapping both the presence and absence of information in memory.
This diagram is in Nelson and Narens (1990) (p. 164)
Results indicated in the above diagram confirms the dual-counter hypothesis.

b. Relation between ongoing FOK and the latency of recall errors.
The substantial correlation between FOK and the latency of omission errors indicates that people's FOK affects whether the overall retrieval stage with be continued or terminated. However, the correlation between FOK and the latency of commission errors is nil for general-information items.  The difference could be considered as the manifestation of the differential mechanism involved as shown in figure 5 above.

c. Relation between metacognitive confidence judgments and the latency of recall.
While the latency of recall affects the confidence of judgment, distance between the the curves showed that something else is affecting people's confidence.  

This diagram is in Nelson and Narens (1990) (p. 167)

Love how the authors put it... "We do not yet know what that something is, but future research should attempt to isolate and identify it."

One thing I found most interesting is the notion of feeling of knowing (FOK)... 

A lot of times, this is how delusions manifest themselves... no hallucination and anything else attached... simply the FOK dropping by and landing on the working memory... like... I knew the the apocalypse was coming again, I know they are checking out everything I do including my internal blog, I know they are talking about this blurb I am working on now, or I know some other things a like out of no where that I have never known and maybe in contexts I have never been in.  How do I know it?  I could feel it... the gut feeling... I just know it, believe it. (Of course, this FOK I have spoken of up to this point might not be the FOK Nelson & Narens (1990 ) were talking about... unless... it's about one of the multiple manifestations of the same principle?  Donno.)  

Then, I would have the FOK about the above FOK... something fishy there... feels like delusions... Even before I have to explicate to myself which part of the scenario seems delusional, I intervene by means such as what Ramsey said to some chefs... "Out! Out! Out!"

So I came across the notion of FOK and the associated research findings... as well as the no-magic hypothesis... as summarized above... Then, I thought... a good way of conceptualizing the fishy kind of FOK... it surely could be true that, after being delusional for over a decade, I must have enough delusions encoded in my LTM to boost up the accuracy rate of my FOK.  My head might have, somehow, figured out the attributes of delusional dasein, which, theoretically, is the basis of how FOK works... in spite of my inability to have it articulated.  If this is really how it works, it would be really beneficial for my head since the last thing I need is to constantly access my memories of psychosis... not to mention that the constant access might strengthen the path towards them and make them easily activated.

At the same time, since I treat all observations with uncertain intents as symptomatic... allowing for false positive, I don't need the FOK to be accurate in all perspectives... as long as no false negative.

Flavell (1979) Metacognition and cognitive monitory--In Ratprincess' eyes

Flavell's definition of Metacognition: knowledge and cognition about cognitive phenomena.  Metacognition plays an important role in tasks like language acquisition and problem solving.  The notion of metacogntion is applied in areas such as cognitive behavior modification (CBT?)

Flavell's model of cognitive monitoring

Flavell considered cognitive monitoring is done through the actions and interactions of four classes of phenomena: a) metacognitive knowledge, b) metacognitive experiences, c) goals/tasks, and d) actions/strategies.  Metacognitive knowledge and experiences are considered to differ from cognitive knowledge and experiences in the nature and contents--but not in the form or quality.

Metacognitive knowledge:

  1. Flavell's definition: The segment of knowledge that has to do with people as cognitive creatures and with their cognitive tasks, goals, actions, and experiences.
  2. Ex. I have disordered thinking and my reality might not be shared by the others.

Metacognitive experiences:

  1. Flavell's definition: Any conscious cognitive or affective experiences that accompany and pertain to any intellectual enterprise.
  2. Ex. Before Valentine's Day, 2008, I had the metacognitive knowledge that my psychotic symptoms were really bad but I failed to observe enough symptoms to match up with my expectations.

Goals/tasks

  1. Flavell's definition: The objectives of a cognitive enterprise.
  2. Ex.  Detect delusions.

Actions/strategies

  1. Flavell's definition: The cognition or other behaviors employed to achieve the goals/tasks.
  2. Ex.  Match observations with established corpus of contents, behavioral patterns, and impacts of delusions.

Metacognitive knowledge

Flavell (1979) considered metacognitive knowledge to consist of "knowledge or beliefs about what factors or variables act and interact in what ways to affect the course and outcome of cognitive enterprise."  He also classified these factors into three major categories--person, task, and strategy.

Person

  1. Intraindividual differences:  I can handle my head better with the tactics than without.  
  2. Interindividual differences:  The tactics working for me might not be appropriate for the others
  3. Universals of cognition:  There are different degrees of proficiency we can achieve in the different learning tasks--the application of the tactics.  Sometimes it might be difficult for us to detect our defects and control it with the workarounds.  You also have the insight that you might not be able to perform later what you can able to perform now and vice versa.

Task

  1. The nature of information:  The nature of information (e.g., contaminated by psychotic symptoms) might make it difficult to warrant "accurate" (i.e., align with the reality shared by the others) judgments about the "world." 
  2. Task demands and goals:It's harder for me to engage in higher-order cognitive processing without invoking the symptoms.

Strategy

It's possible to devise strategies that can be effective to achieving the goal of neutralizing and negating delusional notions--such as airplane flying in the sky and flight 1549.
"Metacognitive knowledge is not fundamentally different from other knowledge stored in long-term memory."  As a result, it can be retrieved through either deliberate conscious search (e.g., the search for a strategy) or be done unintentional and automatically.

Metacognitive knowledge can be...
  1. Inaccurate: I allow for false positive... all observations with uncertain intents are classified as symptomatic.
  2. Fail to be activated: You can't detect delusions that's already classified by your head as the reality shared by the others.
  3. Fail to have much or any influence when activated: The general awareness that I am delusional itself sometimes doesn't stop the delusion to have impacts on me.
  4. Can fail to have a beneficial or adaptive effect when influential: When the symptoms were bad back in the era of origami, around the time when Dr. Strauss used to come visit me, origami worked for certain times and the focus on origami calmed my head down after getting overheated.  Then, at some time, when the symptoms were more on the wildside again, origami surely calmed the head down but, when concentrated on papge folding, the voices became even more prominent since all's quite except for the voices.  Though... I did pull it through...
Metacognitive knowledge can lead people to "select, evaluate, revise, and abandon cognitive tasks, goals, and strategies in light of their relationship with one another and with your own abilities and interests with respect to that enterprise."

For the perspective of the delusional enterprise, there is something interesting about the notion of abandoning cognitive tasks, goals, and strategies.  So, for instance, when doing literature review now, I would hear people say things like I am a copycat...  instead of making it a goal to figure out how they get the up-to-date information on what I had just done and find the strategies to intervene accordingly and how they are wrong... as a delusion, upon the observation, I have to abandon that default task and shift to the task of negating the belief in formation to prevent the further build up of the delusional system and conspiracy theory.

Metacognitive experiences

"Many metacognitive experiences have to do with where you are in an enterprise and what sort of progress you are making or are likely to make."
How psychotic am I today in comparison to, say, one week ago before the dosage change with the enterprise being the psychotic enterprise.  This sentence speaks for the inconnectedness between metacognitive knowledge and experiences since how I feel involves the comparison of my metacognitive knowledge about my state of being a week ago and the new metacognitive knowledge derived through my recent experiences.

Metacognitive experiences are especially likely to take place in situations that requires "careful, highly conscious thinking"... such as as when decisions and actions are both weighty and risky, and where there is absence of high affective arousal or other inhibiting factors (e.g., Langer, 1978).
The decisions I make and actions I take in handling my psychotic symptoms are surely weighty and risky.  History has taught me the lesson of one step wrong... whole path wrong.  That should be weighty and risky enough.
Metacognitive experiences and effects on cognitive goals/tasks, actions/strategies, and metacognitive knowledge
  • Metacognitive experiences can lead you to establish new goals and to revise or abandon old ones.
  1. Instead of running my head on where the surveillance devices are, change the goal to getting better in using workarounds to negate and neutralize the symptomatic observations
  • Metacognitive experiences can affect your metacognitive knowledge base by adding to it, deleting from it, or revising it... the Piagetian notion of assimilation and accommodation.
  1. This is why I went direct into the cuckoo's nest the second time.  I had insufficient metacognitive knowledge base on tasks such as symptom detection, which are derived through metacognitive experiences.
  • Metacognitive experiences can activate cognitive or metacognitive goals.  The purpose of cognitive strategies are to make cognitive process and that for the metacognitive strategies is to monitor the progress.
  1. Cognitive goals and strategies: I sense my defects arising, it activates the retrieval of appropriate intervening strategies... such as airplane flying by... flight 1549.  The workarounds are the cognitive strategies aim at stopping the buildup of my delusional system.
  2. Metacognitive goals and strategies: Now I applied the cognitive strategy to intervene, the metacognitive goal I have is to assess the level of impact the intervention has, how well the cognitive strategy works, how I can improve upon the intervention, what else can be done (thereby generating another metacognitive experience)
However, the effects might not be as clear-cut.  For instance, the monitoring of the effects of my cognitive goal might also result in the improvement.

At the same time, as per Flavell, the store of metacognitive knowledge might contain both cognitive and metacognitive knowledge.  

Developmental and educational implications

A differentiation process, Children's development in the notion of understanding--the universal
  1. Understanding or not understanding
  2. The level of understanding
  3. The difficulties involved in making accurate assessments and associating factors (e.g., intense affect, mental or physical illness.)
Questions posed by Flavell:
How much good does cognitive monitoring actually do us in various types of cognitive enterprise?
Some good... in the psychotic cognitive enterprise...
Might it not even do more harm than good, especially if used in excessive or nonselectively?
Excellent question, that's why the identification of tactics to use our head in more selective fashion so that we don't overheat it.
Think of the feckless obsessive, paralyzed by incessant critical evaluation of his own judgments and decision?
Interesting notions here... In reality, delusionals are by default floating in a sea of critical evaluations on their judgments and decision.  This is why, since we are already doing it in our everyday life, might as well do it in a way--away from harm's way.  
Flavell's personal opinion: Training on metacognition is possible.  For instance, Brown, Campione and Barcly  trained children with learning challenges to use self-testing strategies on certain tasks.  A year later, when these kids were tested on the same tasks again, not only were they able to applied the strategies they were taught, some even modified the strategies to make them more effective.

"In many real-life situation, the monitoring problem is not to determine how well you understand what a message means but to determine how much you ought to believe it or do what it says to do."

Absolutely the real life statements for psychotics... shall I believe in my delusions or shall I do what my hallucinations tell me to do?  Shall I cut myself to save some blood because they were going to swap the sample (my second full-blown episode)?  For psychotics, we need to learn as per the words of Flavell "how much you ought to believe it or do what it says to do"--what you see, what you hear, and what you think.  When defects are detected, your search for the most pertinent cognitive strategies to intervene, and further assess how well your intervention achieved the cognitive goal of stopping the build up of the delusional system.

Prevalence rate of Psychosis

In search of the estimated prevalence rate of psychosis:

England: Meta-analyses with pooled statistics 31.7/100,000 person per year Incidence of Schizophrenia and Other Psychoses in England, 1950–2009: A Systematic Review and Meta-Analyses

Finland: Population study yielding 3.06% (3.48% when nonresponding group with diagnosis included) Lifetime Prevalence of Psychotic and Bipolar I Disorders in a General Population

In addition, some other stats to entertain although I have not checked the original sources

Office For National Statistics, London, 2002
  1. 4 women per 1,000 women aged 16-64 with a psychotic disorder in England and Wales 2000
  2. 5 men per 1,000 men aged 16-64 have a psychotic disorder in England and Wales 2000
  3. 4 per 1,000 population aged 16-64 in England and Wales 2000 with a psychotic disorder
In addition, just by looking at the prevalence rate of Schizophrenia (not counting other types of psychotic disorders)... approx 1 in 123 or 0.81% or 2.2 million people in USA.

Which estimate is closer to the global true score?  

Regardless... ain't quite so impossible for one to be affected by psychosis... I guess?!

No threat intended... but anyone could become one of us.  Guess it's why it's important to study psychosis and find ways to intervene... though the prevalence rate isn't exactly high... it ain't so low.  sigh

Run by or run through

When I was at a dinner yesterday, they were talking about a Japanese restaurant and I said to this lady who originally came from Japan... "All they have to do is to run it through you..."

Sounds weird to me (should it be "by" instead) and them English speakers seemed to have problems comprehending my English as well... lol

So I looked it up in the dictionary for the appropriate usage of the runs... 8-O lol

ALSO... it should've been "run by" instead of "run through." 

Dictionary definition as per Merriam-Webster dictionary online:
— run by or run past
: to present to (as for evaluation) <ran some ideas by her>

Running through, apparently, means something else... oops... (guess, I have to let Ratology run itself through to the extend that I thought "through" is the only thing to follow "run"... 8-O 8-X lol)

One more of them mistakes down!

Friday, February 1, 2013

My mistakes etc.

I find myself using "etc." a whole lot in writing (in Ratology).  Two questions that came two me were whether I need an "and" before "etc." and whether I need another period if "etc." is used at the end of the sentence.

Apparently, I am not along on this planet with these questions--which made it relatively easier to find the answers:

  1. There is no need for an "and" before "etc."  "Etc." is the abbreviation for the Latin expression et cetera where "et" means "and," and "cetera," "the rest".  Thus, saying "and etc." could be like saying "and and the rest"--the "and" is therefore redundant.      
  2. Don't double up periods.  One period is enough--the period after the abbreviation can also serve as the period.  It is also recommended to write the whole phrase out or to avoid placing abbreviations (e.g., etc.) at the end of sentences.  Yet, when the sentence ends with either an exclamation mark and question mark, you need to keep both punctuation marks. 

In the processing of searching for the answers to the aforementioned questions, I found more issues that I were not even aware of...

According to the Chicago Manual of Style, "etc." is preceded by a comma and should be "(unless it ends a sentence) followed by a comma when it is the final item in a series" (6.20 Commas with “etc.” and “et al.”).  "Etc." should also not appear "at the end of a list that begins with e.g. (or phrases similar to such as, for example), which properly introduces a short list of examples."  In addition, "[etc.] should never be used in reference to people... (and indeed it should be used only after at least two items, never just one). But often writers seem to run out of thoughts and tack on etc.for no real purpose." 

Also, as per the definition of "etc." on dictionary.com, "etc." is "used to indicate that more of the same sort or class might have been mentioned, but for brevity have been omitted."  The way I read it... though it can be a catch-all phrase--it can only be a catch-all phrase for things of the same class (e.g., fruit, animal, dinos).  Yet, don't use it if people are unfamiliar with the items with the class.

I am going to end this post by identifying the mistakes I have made so far in my life concerning the usage of "etc.":

  1. Put an "and" before "etc."
  2. Might have put an additional period after "etc."
  3. Might have not put a comma after "etc."
  4. Left out the period for the abbreviation.
  5. Used "etc." when the list began with "e.g.," "such as," "for instance," or "for example."
  6. Used "etc." in a list with less than two items.
  7. Used "etc." simply because I ran out of thoughts.
  8. Used "etc." when items in the list might not belong to the same class.
So it is--my preferred Bad English is my preferred Bad English and mistakes are mistakes.  My lessons learned for the day--mistakes etc. 8-O lol

Candy-countable or uncountable?

Nowadays, I am getting super-insecure about whether nouns are countable or uncountable.

So I came across this sentence du temps passé... "Don't eat too much candy..." and I went... ummmmm... too much candy or too many candies? 8-O

Then, of course, over 2 decades after this word became part of my dictionary, I have to look it up in someone else's dictionaries.  8-O lol

While some of the dictionaries stated that the plural of "candy" is "candies," so the Cambridge Dictionaries Online has the word "candy" defined:

› a small piece of sweet food made from sugar with chocolate, fruit, nuts, or flavors added:
[U] We dove into the box of chocolate candy as if we were starving.

An uncountable mass noun like water... plural when referring to different kinds of candies...

At least, from now on, yours sweet tooth will know that candy is a mass noun--something I must have learned but don't even recall when I had it forgotten... lol

Comma after conjunctions like "And," "But," "So"

Now that I have established to myself that it is OK to start a sentence with conjunctions, I have to figure out whether it is kosher to place a comma after conjunctions (e.g., and, but, so)--yet another incurable propensity of mine.

Based on the sources that endorse or do not fully disapprove such practice, it seems like it is OK to do it if:

1.      what follows the comma is a parenthetical sentence
2.      what follows the comma is a conditional clause
3.      The conjunction is used as a "discourse particle," which has a pragmatic function (e.g., indicating the tone, attitude) but no direct semantic meaning in the sentence--with the consensus on its definition yet to be reached. 

So I ran the above through my friend who is a veteran copy-editor...

While he gave me the ok on my summarization, he also recommended that, when in doubt, leave it out, and it's "best not to start too many sentences that way." (Oops... it's not me... it's my head... lol)

Interestingly, in the Cambridge dictionary, I found several official examples using the conjunction "so" as the sentence starter followed by a "comma."
  • used at the beginning of a sentence to connect it with something that has been said or has happened previously
  1. So, there I was standing at the edge of the road with only my underwear on ...
  2. So, just to finish what I was saying earlier...
  • used as a short pause, sometimes to emphasize what you are saying
  1. So, here we are again - just you and me.
  • used before you introduce a subject of conversation that is of present interest, especially when you are asking a question
  1. So, who do you think is going to win the election?
Don't know what you might think... yet, I can't help but wonder whether the section of "so conjunction (SENTENCE BEGINNING)" has always been included in the dictionary... especially after reading the discussions in the following discussion forum listed under the title of discourse particle.


The resources I found are as follows:


Discourse particle 
I find the discussions in the following forum to be extremely interesting, and decided to copy and paste  parts of the discourses here.  Beyond my wildest imagination--stimulating discussions as such could take place on what I thought was just a bad habit of my head....
http://www.linkedin.com/groups/Commas-after-But-So-Now-1822758.S.89542633

Ann B. • I don't see it as being a literal need for breath, but as the desire for the pause or intonation which, regardless of 'need', is intended by the author.
Iulia D. • Intonation is meaningful, and punctuation gives clues to intonation.
John H. • I agree there is no need for these commas... In short, I don't think MOST style guides endorse this practice, but they don't condemn it.
Kathryn M. •...I think the reason is that in that example the comma is necessary to an understand of the meaning of "now". "Now I'll go by myself" clearly means "I will go by myself at this time," whereas in "Now, I'll go by myself" "now" seems to be functioning as a discourse particle with no specific connection to the time of the events. (Now, I'll go by myself. But don't think that means I've forgiven you for cancelling at the last minute.)
Kathryn M. • ...I also found it interesting that, in introducing the uses of the comma, M-W says it is "ordinarily" used, whereas in introducing all other punctuation marks it says "a _____ is used." This suggests that the M-W editors recognize that, as fashions in comma usage have changed significantly over the last century, and fragments of the old system are still in use by many, it is essentially impossible to state what is in fact correct at all times.
Iulia D. • I think the only rule that stands in grammar is that each point should be logically justified or justifiable .. There is such variety in the world, that adherence to very strict rules without allowing for flexibility, for variation, is like saying that all men should have the same height.
Kathryn M. • ..."so" seems to be used by many (well, I know I use it) as a discourse particle at times. I think "discourse particle" could appropriately be added to the M-W list, except, of course, that discourse particles aren't a part of standard written speech. However, in settings such as this--where written speech is used in a conversational mode--I believe that setting the discourse particle off with commas is, like, pretty standard.
Mim E. • Definitely, like, discourse particles should be set off by commas in the middle of a sentence, but I still resist using them after introductory conjunctions unless those Ands and Ors are being used as mild interjections, which I don't think they ever are, as Now often is.
Nick Trainor • ...Seeking to enforce a viewpoint which doesn't admit of the highly diverse ways that language is used seems quixotic. Idiosyncracy is fine, but if we didn't admit change, subtlety, nuance, and diversity then we would all be speaking as Chaucer spoke and wouldn't have learnt anything from Shakespeare, or the King James Bible, or anything that has come after... do we need to go back to Bede, or maybe Anglo-Saxon, uses of the comma? Grammatical rules are snapshots in time of how folks sought to make better ways to understand each other. Those rules change because folks find new and innovative ways to look at the world, at each other, and our relation to these things...
If we won't admit of change, then at least we all have to acknowledge the contingent nature of our position.... but 9 times out of 10 that rule is quite a young beast in terms of the lifespan of the English language... It has popped its head above the parapet for a while, but it is just as likely to get its head shot off - as has happened to other rules before it.
So, this is an argument from the contingent and, therefore, historically relativised nature of a rule against using commas in funny ways. I would hope it goes some way to give us pause for thought when we start asserting things as wrong in the face of increasingly accepted change.
I haven't argued from the viewpoint of language as communication (the place of the writer) or reception (the place of the reader) but I suspect there are strong arguments against getting wrapped up in strident assertions of right and wrong ways to use commas from these standpoints too. But, as you Americans say: I have written enough already...

Pain--countable or uncountable


The notion of pain is a royal pain in the neck (literally), and it is a real pain trying to figure out whether my pain is countable or uncountable.  So I came across my own writing such as Phenomena.  Da mals I was careless with "pain"; today, I feel the pain--in all capacities--when having to go back to edit my own writing.

The question of the day: my pain-countable or uncountable?

I went through almost all dictionary definitions I could find online on the sensation called physical pain; yet, despite of all efforts, and after the aches and pains resurrected for working too hard and too long, I still can't quite figure out the principle behind the usages given by these dictionaries, and I have no idea what the point is for them dictionaries to simply indicate in one setting that a word is "uncountable and countable."  Can you be even less specific, please?  

At some point, I thought... OK, based on the examples provided by these dictionaries, the word "pain" can be treated as countable if it comes in bouts... like it shots, shots, shots, and throbs, throbs, throbs...  Yet, the example provided by Dictionary.com got me all confused again with the example of "a back pain."  For someone like me with chronic pain, a back pain--like it happens and disappears immediately kind of back pain?  (Can I have that pain instead, please?) 8-O

Then, I went back to them discussion forums I found online and decided to subscribe to the following explanation (http://forum.wordreference.com/showthread.php?t=1925818):

The slightest shift causes excruciating pain - it causes pain as a generalised concept.
The slightest shift causes an excruciating pain - it causes a specific sensation of pain which is locatable in time and space.

Already in pain, don't need more pain on pain, and don't wanna know more pain... speaking of no pain, no gain. 8-O 8-X lol sigh

    Too much inconvenience or too many inconveniences?

    Found a sentence somewhere in my writing... something like, "...psychotic, neurotic and physically handicapped--a bit too much inconvenience..."

    Too much inconvenience sounds fine but... wait a minute... shall it be too many inconveniences or too much inconvenience?  Or is the word "inconvenience" countable or uncountable?

    After some googling around with all due diligence, I found in some discussion forums where it was stated that  the word "inconvenience" could be treated as a mass noun "if it was just in general a huge hassle getting everything straightened out" and, as countable, "if there are a sequence of well defined inconveniences" --although, while both are acceptable, the usage of "much inconvenience is probably more common."


    Well, it sounds comforting, to a certain degree, that both usages are acceptable; yet, since I have itemized quite a few minor inconveniences in life, do I have to change my sentence to "too many inconveniences"?

    So I looked to see how the word "inconvenience" is defined when assuming the role of an "uncountable mass noun":

    As a result, I figure that "too much inconvenience" might be OK in the context of my own writing if, with the word "inconvenience," I am referring to the general state of being that poses difficulties to my daily living?

    Don't know what the experts might say... but... seems to be good enough a justification for myself, especially in my informal writing--conversation style... 8-O lol

    BTW, when editing my own bad English in a Cafe today, this guys next to me asked this question, "Are you an English teacher?"  So I replied, "No.  I am but trying to correct my own old writing [and mistakes].  Ya.  The "English kinda thing" documents my attempts to correct my Bad English and to share the references I find.  In no way do I intend to teach nobody no English through my blurb--just as I intend not to teach nobody how to be a neurotic and psychotic handicap in Ratology Reloaded or Down with Meds.

    Historic vs. historical?

    While my vocabulary is limited to begin with, I have an even smaller vocabulary in the history domain, just as that in the "food" department.  When translating a paper about a history textbook collaboration effort between China and Japan, one stupid question that really got me confused was the difference between "historic" and "historical." (And, ya, never knew that question existed either until then...)

    What I figure so far is that, when the adjective "historic" is used, what you describe is something famous and of great significance.  However, the longer adjective "historical" simply means what you intend to describe has something to do with the study or the representation of du temps passé... history.

    This is what I gathered so far based on the following sources.  Can't assure you I am 100% correct or not since I am only reporting to you what I have learned.  You are more than welcome to construct your own understanding based on the following references.

    [Historic]
    Cambridge dictionaries online
    (of a thing or event) important when studied as part of the past: historic buildings and monuments
    Merriam-Webster dictionary
    a. famous or important in history
    b. having great and lasting importance
    c. known or established in the past
    d. dating from or preserved from a past time or culture
    Oxford Dictionaries online
    famous or important in history, or potentially so: we are standing on a historic sitea time of historic change

    [Historical]
    Cambridge dictionaries online
    connected with the study or representation of things from the past: The library has an important collection of historical documents.
    Merriam-Webster dictionary
    a. of, relating to, or having the character of history
    b. based on history
    c. used in the past and reproduced in historical presentations
    Oxford Dictionaries online
    of or concerning history; concerning past events: the historical background to such studies

    [Historic vs. Historical] 
    Oxford Dictionaries online
    In general, historic means ‘notable in history, significant in history,’ as in a Supreme Court decision, a battlefield, or a great discovery. Historical means ‘relating to history or past events’: (historical society; historical documents). To write historic instead of historical may imply a greater significance than is warranted: a historical lecture may simply tell about something that happened, whereas a historic lecture would in some way change the course of human events.
    Chicago Manual of Style online
    The shorter word refers to what is momentous in history {January 16, 1991, was a historic day in Kuwait}. Historical, meanwhile, refers simply to anything that pertains to or occurred in history.
    Grammar Girl
    “Historic” is an adjective that means something important or influential in history... “Historical,” on the other hand, is an adjective that refers to anything from the past, important or not.

    Begin sentences with conjunctions (and, but, or, etc)?

    Apparently, some people were taught in school to never begin a sentence with conjunctions such as "and," "but," and "or."   It must be my old age or I didn't pay enough attention to my dear teacher when in school... I totally had no idea about this one as well until this issue was revealed to me.

    Then, when going through my writing in DWM, I found this incurable propensity of mine to start sentences with conjunctions such as "and," "but," "or," etc.  To cut down on the changes I have to make on the utterances of da moi du temps passe, I decided to look for trusted sources to support such usages.

    Based on what I have gathered so far, there is nothing wrong about starting a sentence with conjunctions such as "and," "but," etc.  Moreover, so it says on the Oxford Dictionaries website: "many respected writers use conjunctions at the start of a sentence to create a dramatic or forceful effect" and "[use] 'and' to start a sentence, typically for rhetorical effect."

    Cambridge Dictionaries Online also has a dedicated section on using "so" to begin sentences and provides numerous examples (though don't know whether it's British style only?):

    • used at the beginning of a sentence to connect it with something that has been said or has happened previously
    So, there I was standing at the edge of the road with only my underwear on ...
    • used as a short pause, sometimes to emphasize what you are saying
    So, here we are again - just you and me.

    The following quote of Charles Allen Lloyd in his book, "We who speak English and our ignorance of our mother tongue," was cited in the Chicago Manual of Style (5.206: Beginning a sentence with a conjunction) and various other sources (e.g., Garner's Modern American Usage, Dictionary of Modern Legal Usage):
    Next to the groundless notion that it is incorrect to end an English sentence with a preposition, perhaps the most wide-spread of the many false beliefs about the use of our language is the equally groundless notion that it is incorrect to begin one with “but” or “and.” As in the case of the superstition about the prepositional ending, no textbook supports it, but apparently about half of our teachers of English go out of their way to handicap their pupils by inculcating it. One cannot help wondering whether those who teach such a monstrous doctrine ever read any English themselves.

    Bryan Garner also provided additional quotes by other authors who intended to debunk the notion of "Never Begin a Sentence with And or But" in his 2009 book "Garner's Modern American Usage" published by the Oxford University Press.






    However, writers do need to make sure what comes after the conjunctions are "complete sentences."  Some authors speculated that one reason why teachers try to dissuade pupils from starting sentences with conjunctions is to prevent pupils from constructing incomplete sentences (e.g., "I have a cat. And a dog.").  Apparently, it might be easier to stop young pupils from beginning sentences with conjunctions than to explain to them that complete sentences are required after these conjunctions. (See "Can I begin a sentence with a conjunction?" on Dictionary.com and "conjunction beginning a sentence" on Random House website.)  At the same time, dictionary.com does mention on their website: "In formal writing, it is best to avoid beginning any sentence with a conjunction." (Pourquoi?  Je ne sais pas. Just a recommendation, I guess? 8-O)

    So it is.  What I learn to date on the issue of "beginning a sentence with conjunctions."  Hope hope I learn is of some help to you, too!
