The attentional demands of encoding and retrieval in younger and older adults: 2. Evidence from secondary task reaction time distributions

Three studies examined the effects of encoding or retrieval on properties of secondary task reaction time (RT) distributions in younger and older adults. Relative to full attention conditions, encoding and retrieval increased secondary task RT medians and standard deviations more for older adults than for younger adults, and the age-related RT increase was most pronounced among the slowest RTs. Hierarchical regression analyses revealed two age-related mechanisms underlying these effects, which were interpreted as cognitive slowing and reductions in attentional resources. Cognitive slowing affects the entire RT distribution regardless of the memory task. By contrast, reduced attentional resources result in very long RTs, especially when the tasks require self-initiated encoding or retrieval operations.     

Clinical features of major depressive disorder in adolescents and their relatives: impact on familial aggregation, implications for phenotype definition, and specificity of transmission

Three questions were addressed using family study data from a community sample: (a) Which clinical features of major depressive disorder (MDD) in adolescents are associated with elevated rates of MDD in relatives? (b) Which features of MDD in relatives distinguish family members of depressed adolescents from relatives of adolescents without mood disorders (NMD)? and (c) Do depressed adolescents with particular features have higher proportions of depressed relatives with the same features? Participants included 268 MDD adolescents, 401 NMD adolescents, and their 2,202 first-degree relatives. Rates of MDD were highest among relatives of depressed adolescents with recurrent episodes and greater impairment. Depression severity best distinguished the relatives of depressed adolescents from relatives of controls. Specific clinical features did not aggregate in families.     

Structuring Case-Based Ethics Training: How Comparing Cases and Structured Prompts Influence Training Effectiveness

This study examined how structuring case-based ethics training, either through (a) case presentation or (b) prompt questions, influences training outcomes. Results revealed an interaction between case presentation and prompt questions such that some form of structure improved effectiveness. Specifically, comparing cases led to greater sensemaking strategy use and decision-ethicality when trainees considered unstructured rather than structured prompts. When cases were presented sequentially, structuring prompts improved training effectiveness. Too much structure, however, decreased future ethical decision making, suggesting that there can be too much of a good thing when structuring case-based ethics education. Implications for designing ethics training programs are discussed.     

An evaluation of response cost in the treatment of inappropriate vocalizations maintained by automatic reinforcement

In the current study, we examined the utility of a procedure consisting of noncontingent reinforcement with and without response cost in the treatment of inappropriate vocalizations maintained by automatic reinforcement. Results are discussed in terms of examining the variables that contribute to the effectiveness of response cost as treatment for problem behavior maintained by automatic reinforcement.     

Anti-Racism Strategies in Pediatric Psychology: Using STYLE Can Help Children Overcome Adverse Experiences With Police

Black children are exposed to police violence at alarming rates. Such stress impacts development and treatment of physical health problems. In the current discourse, we introduce STYLE (Self-examination, Talk about community-police relations and racism, Yield space and time to anti-racism work, Learn about how structural racism impacts child health, Evaluate policies and practices through an anti-racism lens). STYLE offers a framework through which professionals in pediatric psychology can engage in anti-racist work across contexts from clinical care to academic and advocacy settings. Pediatric psychologists have a responsibility to be on the frontline as interventionists, educators, researchers, organizers, and advocates for racial justice through anti-racism practices. The current paper introduces STYLE in clinical care, community service, training/supervision, and academic and advocacy contexts. Case examples are provided. Professionals in pediatric psychology must first focus on changing their STYLE to promote individual and infrastructural change consistent with anti-racism work.

     

Striatal sensitivity to personal responsibility in a regret-based decision-making task

Regret and relief are complex emotional states associated with the counterfactual processing of nonobtained outcomes in a decision-making situation. In the “actor effect,” a sense of agency and personal responsibility is thought to heighten these emotions. Using fMRI, we scanned volunteers (n = 22) as they played a task involving choices between two wheel-of-fortune gambles. We examined how neural responses to counterfactual outcomes were modulated by giving subjects the opportunity to change their minds, as a manipulation of personal responsibility. Satisfaction ratings to the outcomes were highly sensitive to the difference between the obtained and nonobtained outcome, and ratings following losses were lower on trials with the opportunity to change one’s mind. Outcome-related activity in the striatum and orbitofrontal cortex was positively related to the satisfaction ratings. The striatal response was modulated by the agency manipulation: Following losses, the striatal signal was significantly lower when the subject had the opportunity to change his/her mind. These results support the involvement of frontostriatal mechanisms in counterfactual thinking and highlight the sensitivity of the striatum to the effects of personal responsibility.     

The role of angles in inducing misalignment in the poggendorff figure

Much experimental evidence has been put forward against the idea that angles are necessary for the occurrence of the Poggendorff illusion. We show that five separate alignment illusions can be demonstrated in the Poggendorff figure according to its orientation, length of the parallels, and so on. In one of these (angle-caused misalignment) angles are a necessary component. The main source of the belief that angles are not necessary is the alignment illusion (attraction-caused misalignment), which is due to the action of the distant parallel on the transversal that does not abut it. We show finally that it is unlikely that the angle-caused misalignment illusion is due to a change in the apparent size of the angle.     

Smoking research: basic research, intervention, prevention, and new trends

Smoking is a behavior that is influenced by a variety of factors that cut across methodologies, disciplines, and content areas within health psychology. The present article is designed to show the diversity and richness of smoking research by examining smoking from four perspective: basic laboratory research, intervention, prevention and deterrence, and new directions in smoking research. Methodologies that were derived from such varied sources as psychopharmacology, behavioral pharmacology, behavior therapy, clinical psychology, public health and health promotion, and social and developmental psychology have been used to study the smoking problem. The subject populations in these investigations ranged from animal models, to the individual smoker attempting to quit, to communities involved in health promotion and public health approaches. Future research should seek to provide new and improved examples of interdisciplinary research within the field of health psychology to multidisciplinary approaches from the basic and applied sciences.
