Relating inter-individual differences in metacognitive performance on different perceptual tasks

Human behavior depends on the ability to effectively introspect about our performance. For simple perceptual decisions, this introspective or metacognitive ability varies substantially across individuals and is correlated with the structure of focal areas in prefrontal cortex. This raises the possibility that the ability to introspect about different perceptual decisions might be mediated by a common cognitive process. To test this hypothesis, we examined whether inter-individual differences in metacognitive ability were correlated across two different perceptual tasks where individuals made judgments about different and unrelated visual stimulus properties. We found that inter-individual differences were strongly correlated between the two tasks for metacognitive ability but not objective performance. Such stability of an individual’s metacognitive ability across different perceptual tasks indicates a general mechanism supporting metacognition independent of the specific task.     

Effect of temporal locus of a recitation attempt on learning and retention

In three experiments, analyses of individual-subject data show that temporal point of interruption for a practice recitation of a serial list affected neither the ultimate amount of time needed to master that list nor the amount of time needed for remastery 24 h later. Learning and relearning were by the unpaced whole-presentation method, with scheduled test interruptions at different stages of original learning.     

Agency regarding our reasons

ABSTRACT

How much control do we have over our reasons for action? Not much, but some. We all have reasons to avoid pain and not to inflict it on others. What explains our shared reasons? On an externalist account, reasons are grounded in values. All reasons are external to agency. This ensures that reasons are universal, so it is an attractive feature of moral and prudential reasons. However, when our reasons differ this is less attractive. In some cases, it seems like something internal to the agent makes all the difference. There are many valuable things, but an agent can only come to care about a small set of those things. Consider your reasons that stem from your love of philosophy or punk rock. Here it seems we make some reasons our reasons by becoming committed to them. I call these our agential reasons. We express our agency by coming to care about some things in ways not required by rationality. Unlike, matters of taste though, these are not bare preferences we just find ourselves having. Rather these concerns are cultivated over time. We express rational agency by incorporating particular values into our lives.     

Fear of Success in Black Male and Female Graduate Students: A Pilot Study

In accordance with Horner's (1969) assumption that the intensity of fear of success arousal increases with the subject's success potential, graduate students from a prestigious university were chosen for a pilot investigation of the motive to avoid success in black men and women. Thirty-five subjects (14 female; 21 male) received a verbal TAT and a 54-item sex role questionnaire designed for purposes of this investigation. Fear of success was scored according to the new, experimentally derived scoring system for this motive. Contrary to expectation, the results did not indicate any evidence of success avoidance in either sex. However, fear of success in females was clearly associated with striving to develop career interests compatible with their strong commitment to home and husband, while among similarly motivated males it was suggested that the pragmatic career orientation observed was the product of compensatory motivational dynamics. It was concluded that these subjects were motivated to avoid what are perceived to be role-inappropriate behaviors while conforming to socially accepted values internalized in earlier years.
