Simians in the Shape School: A comparative study of executive attention

Executive functions (EF) have been studied extensively in children and adults. However, EF tasks for young children can be difficult to administer and interpret. Espy (1997, Developmental Neuropsychology, 13, 495–499) designed the Shape School task to measure inhibition and switching in preschool-aged children. Shape School presents cartoon-like characters that children must flexibly name by their color, their shape, or both, depending on cues that indicate the appropriate rule. Shape School has been found to be age sensitive as well as predictive of performance on other EF tasks. We presented a computerized analogue of Shape School to seven rhesus macaques. Monkeys were trained to categorize characters by color or shape, or to inhibit this response, depending on whether the characters had eyes open, eyes closed, or wore hats. Monkeys performed above chance on the inhibition and switching components of the task. Long runs of a single classification rule and long runs of noninhibition trials had no significant impact on performance when the rule changed or inhibition was required. This nonverbal adaptation of Shape School can measure EF in nonhuman animals and could be used in conjunction with other EF tasks to provide a clearer picture of both human and nonhuman executive functions.     

The pedagogical benefits of enacting positive psychology practices through a student–faculty partnership approach to academic development

Academic development that supports the enactment of positive psychology practices through student–faculty pedagogical partnership can increase faculty confidence and capacity in their first year in a new institution. When student partners practice affirmation and encouragement of strengths-based growth, processes of faculty acclimation and self-authoring can be accelerated. This article presents a student–faculty pedagogical partnership program and positive psychology practices that focus on faculty strengths and capacities as the foundation for reinforcing and revising existing pedagogical strategies and for sustaining energy for continued development. It combines collaborative autoethnographic and comparative case study approaches to investigate the pedagogical benefits of these practices.     

The GlobalEd Project: Gender differences in a problem-based learning environment of international negotiations

The GlobalEd Project employs a technology richenvironment for high school students who wishto participate in a simulation of internationalrelations and negotiation. A simulationconsists of negotiations on a variety ofinternational policy issues conducted bystudents from 10–15 schools through anInternet-based interface. This study reportsthe findings of 234 high school participants'changes in academic and technologyself-efficacy skills, as well as knowledge,attitudes and behaviors related to academicpreparation and performance, the use ofeducational technology, and associated outcomesfrom participating in a simulation ofinternational relations. The results arediscussed in terms of the current literature onself-efficacy and gender differences incognitive process.     

Student Assessment of Self-Efficacy and Practice Readiness Following Simulated Instruction in an Undergraduate Social Work Program

ABSTRACT

The use of simulated instruction is a growing trend in social work education. This study examined the effectiveness of simulated instruction with undergraduate social work students. In this mixed methods study, the extent to which simulated instruction improved self-efficacy and practice readiness was assessed. Results of the study suggest that simulated instruction helps improve key practice skills and increases recognition of diversity in practice. Moreover, students self-reported increased mastery in interviewing, managing emotions, and engaging in culturally competent practice.     

Self-control in the monkeymacaca fascicularis

Two experiments tested two cynomolgus monkeys’ self-control—choice of a longer, more delayed reinforcer over a shorter, less delayed reinforcer. In Experiment 1, subjects exhibited significant selfcontrol in a procedure in which reinforcer amounts and delays were held constant throughout a condition. In Experiment 2, subjects exhibited significantly greater sensitivity to variation in reinforcer amount than to variation in reinforcer delay in a procedure in which the reinforcer delay associated with the self-control alternative was adjusted until each macaque was indifferent between the two alternatives. Both experiments indicated that, in laboratory paradigms in which humans show self-control and pigeons and rats show impulsiveness, macaques show self-control. These results are inconsistent with the hypothesis that species differences in self-control are a function of language ability or of specific types of prior training. The results are consistent with the hypothesis that species differences in self-control are related to the ratio of brain size to body weight (a possible indicator of general cognitive ability) or to shared phylogeny.     

Perceptions of U.S. Medical Residents Regarding Amount and Usefulness of Sexual Health Instruction in Preparation for Clinical Practice

Despite patient demand for sexual health discussions with their physicians, sexuality instruction in residency is often lacking. This exploratory quantitative study assessed the amount and usefulness of sexuality instruction received by a sample of medical residents, as well as the residents' self-perceived readiness regarding addressing sexuality issues. Data were obtained through a self-administered survey with 130 resident respondents. The majority reported receiving little/no formal sexuality instruction. Many indicated that additional sexuality instruction would be useful in their practice. Although the majority reported comfort discussing sexuality, they reported rarely/never initiating these discussions. Recommendations for changes in graduate medical education programming are provided.     

Accumbens D2: Raters of the Loss Outcome

Zalocusky et al. (Nature 531:642–646, 2016) recently showed that activity in D2R+ cells in the nucleus accumbens is associated with loss sensitivity to prior outcomes and reduced subsequent risky choice, and that optogenetic stimulation of these cells decreased risky choices in risk-prone rats. While their findings are important for understanding trait-level risk-taking, future research should aim to examine the neuronal mechanisms of a broader range of facets of gain and loss processing with respect to different potential reference points.
