Motivated comprehension regulation: Vigilant versus eager metacognitive control

The more accurately people assess their comprehension, the more likely they are to engage in study behaviors that precisely target gaps in their learning. However, comprehension regulation involves more than knowing when to implement a new study strategy; it also involves deciding which strategy will most effectively resolve one’s confusion. In two experiments, we explored how people’s motivational orientations influence which study strategies they select to regulate their comprehension. In Experiment 1, people who were motivated to vigilantly protect against potential mistakes (i.e., prevention-focused individuals) were more likely to adopt a rereading strategy than people who were motivated to eagerly pursue new learning opportunities (i.e., promotion-focused individuals). In Experiment 2, this difference in strategy use emerged specifically in response to confusing sentences that had been inserted into the text. Furthermore, by using rereading strategies to resolve their confusion, prevention-focused individuals performed better than promotion-focused individuals on a comprehension test and a transfer task.     

Cultural bias in the WISC

It is often argued that IQ differences between groups of American Blacks and Whites are the result of IQ tests being culturally biased instruments. The present study attempts to determine the existence of cultural bias in the Wechsler Intelligence Scale for Children (WISC) by comparing Black and White children on: (1) loadings of the first principal component on the WISC subtests; (2) the rank order of item difficulty; (3) measuring the contribution to the total variance of the Race by Item interaction obtained by ANOVA; (4) and by attempting to stimulate race differences by within-race age differences. The results indicate that: (1) there is no evidence of specific factors peculiar to either racial group (the groups differ on what is common to all subtests); (2) the rank order of item difficulties is similar in both racial groups; (3) ANOVA reveals a significant Race by Item interaction, but one which accounts for less than five percent of the total variance, less than one percent in the case of age offset analysis; (4) the items which best discriminate between Blacks and Whites at any age level are also the items which best discriminate between age groups within-race. The data support the view that race differences are differences in mental maturity rather than in artifact of biased testing instruments.     

Does easily learned mean easily remembered?: it depends on your beliefs about intelligence

Because numerous studies have shown that feelings of encoding fluency are positively correlated with judgments of learning, a single dominant heuristic, easily learned = easily remembered (ELER), has been posited to explain how people interpret encoding fluency when assessing their own memory. However, the inferences people draw from feelings of encoding fluency may vary with their beliefs about why information is easy or effortful to encode. We conducted two experiments in which participants studied word lists and then predicted their future recall of those items. Results revealed that subjects who viewed intelligence as fixed, and who tended to interpret effortful encoding as indicating that they had reached the limits of their ability, used the ELER heuristic to make judgments of learning. However, subjects who viewed intelligence as malleable, and who tended to interpret effortful encoding as indicating greater engagement in learning, did not use the ELER heuristic and at times predicted greater memory for items that they found more effortful to learn.     

The structure of individual differences in batteries of rapid acquisition tasks in mice

Two experiments examined the structure of individual differences in mice by means of tasks that produced significant acquisition within 1 session. In Experiment 1, 5 cognitive tasks-detour, winshift, olfactory discrimination, fear conditioning, and operant acquisition-were used in conjunction with two control procedures: an open field and a light- dark test. In Experiment 2, some modifications were made to the tasks used in the 1st experiment, and 3 new tasks were used in conjunction with the same control procedures. The battery consisted of 5 learning tasks: detour, Hebb-Williams, radial maze, olfactory foraging, and fear conditioning. Results of both experiments indicate that when cognitive tasks and control procedures were included in principal-components analyses most of the variance attached principally to individual tasks rather than to a general component as is found typically in human cognitive batteries. When control procedures were eliminated, there was better evidence for the presence of a general cognitive factor, particularly in Experiment 2.     

Web-based, psychosocial treatment for substance use disorders in community treatment settings

The purpose of this multisite clinical trial was to evaluate the effectiveness of a web-based version of the Community Reinforcement Approach, plus motivational incentives, within community-based, outpatient substance abuse treatment. This ongoing study is being conducted within the National Drug Abuse Treatment Clinical Trials Network, funded by the National Institute on Drug Abuse. Midway through the enrollment of 500 participants, the study is being implemented in 10 treatment programs across the United States. Information is provided on design, sample, intervention and technology, and preliminary lessons learned.     

An A to Z guide to DSM-IV conundrums

The work on the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) poses many puzzling conundrums that touch on complicated and important theoretical and practical issues. None of these can be resolved in the DSM-IV, but we hope that the Task Force's decisions will be informed by thorough reviews of the currently available evidence and extensive input from all sectors of the mental health field. In this article we provide an alphabetical guide to DSM-IV conundrums that we hope will stimulate comments, suggestions, and criticisms about the work of the Task Force.
