Resource depletion does not influence prospective memory in college students

This paper reports an experiment designed to investigate the potential influence of prior acts of self-control on subsequent prospective memory performance. College undergraduates (n = 146) performed either a cognitively depleting initial task (e.g., mostly incongruent Stroop task) or a less resource-consuming version of that task (e.g., all congruent Stroop task). Subsequently, participants completed a prospective memory task that required attentionally demanding monitoring processes. The results demonstrated that prior acts of self-control do not impair the ability to execute a future intention in college-aged adults. We conceptually replicated these results in three additional depletion and prospective memory experiments. This research extends a growing number of studies demonstrating the boundary conditions of the resource depletion effect in cognitive tasks.     

Attitudes towards credit and finances among college students in China and the United States

Although there is growing concern about the issue of credit card debt among college students in China, little research has examined attitudes to money and debt among that group. The present study compared financial self‐confidence, perceived financial wellbeing, attitudes to debt, and parent education about money and debt in 410 college students from the US and China. Although college students in China reported fewer credit cards and less debt, they also reported lower levels of financial self‐confidence and financial wellbeing. In both cultures, delay of gratification and parental education predicted both self‐confidence and financial wellbeing.     

Control of Integrated Task Sequences Shapes Components of Reaching

Reaching toward an object usually consists of a sequence of elemental actions. Using a reaching task sequence, the authors investigated how task elements of that sequence affected feedforward and feedback components of the reaching phase of the movement. Nine right-handed adults performed, with their dominant and nondominant hands, 4 tasks of different complexities: a simple reaching task; a reach-to-grasp task; a reach-to-grasp and lift object task; and a reach-to-grasp, lift, and place object task. Results showed that in the reach-to-grasp and lift object task more time was allocated to the feedforward component of the reach phase, while latency between the task elements decreased. We also found between-hand differences, supporting previous findings of increased efficiency of processing planning-related information in the preferred hand. The presence of task-related modifications supports the concept of contextual effects when planning a movement.     

The Relationship of Korean Students’ Age and Years of English-as-a-Foreign-Language Exposure with English-Reading Ability: A Cross-Age Study

The differences in spelling error features among learning disabled and normal students spelling instructionally on four grade levels of achievement were investigated. The categories of errors were determined by invented spelling research. The results indicated that the ranking of error features for each group were significantly correlated, and that the range of individual variation about the mean group pattern of spelling error variables was highly similar at each level of achievement. The findings are congruent with the theory of developmental word knowledge and support the position that learning disabled and normally achieving children acquire specific aspects of English orthography in highly similar progressions.     

READING IS NOT A GUESSING GAME‐THE GREAT DEBATE REVISITED

The present study describes preschool read-alouds in terms of the types of texts to which children are exposed. The methods involved analyzing the genre and instructional foci of 426 titles read by 13 teachers throughout an entire academic year. Additionally, associations between teacher characteristics and texts teachers read in their classrooms were examined. Findings indicated that (a) narrative texts were the dominate genre read-aloud; (b) children's exposure to alphabet books, nursery rhymes, books featuring math concepts, and multicultural content occurred at generally low rates; and (c) few significant associations exist between quantity of books read and teacher characteristics.     

Conditional Associative Learning of Spatial and Object Information in Children with Attention Deficit/Hyperactivity Disorder

The present study assessed frontostriatal mediated memory functions in children with ADHD (N = 12) and healthy control participants (N = 12) using two tests of conditional associative learning (i.e., object and spatial) that shared similar stimulus-response association structures but that differed in terms of the demands placed upon strategic processes. Children with ADHD displayed normal performance on the object learning task but were impaired on the spatial learning task that placed greater demands on internally derived strategic processes. Secondary analyses further indicated that this strategic processing impairment cannot be attributed specifically to perseverative or working memory errors but rather appears to be related to a more general inability to maintain a high degree of consistency in responding across trials. Although the results of this study must be interpreted in light of the small sample sizes, they suggest that ADHD does not produce a basic deficit in acquiring stimulus-response associations previously shown to be associated with basal ganglia dysfunction. Rather, these findings suggest that the impaired conditional associative learning performance of children with ADHD is attributable to deficits in strategic processes previously been found to be dependent upon the integrity of the prefrontal cortex.

Major memory for microblogs

Online social networking is vastly popular and permits its members to post their thoughts as microblogs, an opportunity that people exploit, on Facebook alone, over 30 million times an hour. Such trivial ephemera, one might think, should vanish quickly from memory; conversely, they may comprise the sort of information that our memories are tuned to recognize, if that which we readily generate, we also readily store. In the first two experiments, participants’ memory for Facebook posts was found to be strikingly stronger than their memory for human faces or sentences from books—a magnitude comparable to the difference in memory strength between amnesics and healthy controls. The second experiment suggested that this difference is not due to Facebook posts spontaneously generating social elaboration, because memory for posts is enhanced as much by adding social elaboration as is memory for book sentences. Our final experiment, using headlines, sentences, and reader comments from articles, suggested that the remarkable memory for microblogs is also not due to their completeness or simply their topic, but may be a more general phenomenon of their being the largely spontaneous and natural emanations of the human mind.     

Magnitude and determinants of behavioral risk reduction: Longitudinal analysis of a cohort at risk for AIDS

The magnitude and predictors of longitudinal behavioral change are reported in a cohort of homosexual men at risk for AIDS. Self-reports of sexual behavior were obtained at two points in time separated by an interval of approximately six months. These self-reports were used to construct both dichotomous and continuous measures of changes in behavior consistent with reduction in the transmission of the AIDS virus (HIV). Although there was considerable variability in behavior. mean changes were consistently in the desired direction. Avoidance of anonymous sexual partners, monogamy, and modification of receptive anal sex to reduce exposure to semen by condom use or withdrawal prior to ejaculation appeared to be especially important in this cohort. Both multiple linear regression and multiple logistic regression were used to examine the relationship between a model of health behavior and these outcomes. Variables examined included knowledge of AIDS. perceived risk of AIDS. the perceived efficacy of behavior in reducing AIDS risk, difficulties with sexual impulse control, belief in biomedical technology to provide a prevention or cure, social norms supportive of behavioral change, and gay network affiliation. Of all these factors, only the availability of supportive peer norms was consistently, significantly and positively related to multiple measures of outcome. Differences between these analyses and longitudinal analyses reported elsewhere are discussed. These results suggest the policies regarding HIV antibody testing should be developed cautiously. taking account of the failure of a sense of risk to predict subsequent behavioral change. They also emphasize the important role of gay organizations in developing social norms supportive of behavioral risk reduction.
