Orangutans (Pongo abelii) "play the odds": information-seeking strategies in relation to cost, risk, and benefit

Recent research has examined whether animals possess metacognition, or the ability to monitor their knowledge states. However, the extent to which animals actively control their knowledge states is still not well delineated. Although organisms might be capable of seeking information when it is lacking, it does not mean that it is always adaptive to do so. In the present set of experiments, we examined the flexibility of this behavior in captive orangutans (Pongo abelii; two adults and one juvenile) in a foraging task, by varying the necessity of information-seeking, the cost associated with it, the likelihood of error, and the value of the reward. In Experiment 1, subjects searched for information most often when it was "cheapest" energetically. In Experiment 2, subjects searched for information most often when the odds of making an error were the greatest. In Experiment 3, subjects searched for information more when the reward was doubled in value. In Experiment 4, adult subjects adapted to risk/benefit trade-offs in their searching behavior. In every experiment, subjects sought information more often when they needed it than when they already knew the solution to the problem. Therefore, the current research suggests that information-seeking behavior in orangutans shows a sophisticated level of flexibility, comparable to that seen in human children, as they appear to "play the odds" when making the decision to seek information or not.     

An examination of the factorial dimensionality of the Marlowe Crowne Social Desirability Scale

Using a sample of 555 undergraduate students, the present study examined the factorial dimensionality of the Marlowe-Crowne Social Desirability Scale (MCSDS). In particular, using confirmatory factor analysis, the study explored the goodness of fit of both one and two factor models, the latter of which were based upon the work of Paulhus and Reid (1989). Findings indicate that while both one and two factor models demonstrate many features of adequate fit, the two factor model emerged as superior. The study concludes with a discussion of the meaning of the results and suggestions for future research.     

A measure of within-participant response consistency

In this article, we introduce a measure of within-participant response consistency for use in the analysis of performance in decision-making tasks. The measure is an estimate of the correlation between the responses associated with two identical blocks of trials, the second of which has yet to be conducted. We derive a formula for the measure that can be applied to data from any two-choice decision task, including yes/no detection and two-alternative forced choice (2AFC). The estimate is easily calculated from the observed frequencies of hits, misses, false alarms, and correct rejections. We utilized data from an actual 2AFC experiment to compare estimated and observed consistency values; the estimates accounted for more than 90 % of the variability in observed consistency scores. We also discuss potential applications of the measure.     

Ritual Abuse-Torture Within Families/Groups

Case studies provide insights into identifying 10 violent thematic issues as components of a pattern of family/group ritual abuse-torture (RAT) victimization. Narratives from victimized women suggest that victimization generally begins in infancy or soon thereafter. A visual model of RAT displays the organization of the co-culture. Examples of the family/group gatherings known as “rituals and ceremonies” provide insights into how these gatherings are used to normalize pedophilic violence. Global activism afforded the first effort ever to track RAT and human trafficking. Recognizing RAT as an emerging form of non-state actor torture, discontinuing the use of language that sexualizes adult-child relationships, and promoting human rights education are suggested social solutions.     

The 9th annual INDUS-EM 2013 Emergency Medicine Summit, “Principles,Practices, and Patients,” a level one international meeting,Kerala University of Health Sciences and Jubilee Mission Medical College and Research Institute,Thrissur, Kerala,India, October 23–27, 2013

INDUS-EM is India’s only level one conference imparting and exchanging quality knowledge in acute care. Specifically, in general and specialized emergency care and training in trauma, burns, cardiac, stroke, environmental and disaster medicine. It provides a series of exchanges regarding academic development and implementation of training tools related to developing future academic faculty and residents in Emergency Medicine in India. The INDUS-EM leadership and board of directors invited scholars from multiple institutions to participate in this advanced educational symposium that was held in Thrissur, Kerala in October 2013.     

Transpersonal psychology,physical health,and mental health: Theory,research, and practice

Abstract

Throughout its existence, transpersonal psychology has held a strong interest in exploring the implications of consciousness and spirituality for health, both physical and mental. This article provides a brief overview of the theoretical, empirical, and clinical contributions of transpersonal psychology to the understanding and facilitation of human health and well‐being. It also critiques the methodological basis of some of these contributions, concluding that transpersonal psychological studies of the relationship between spirituality and health are still in their infancy and that practitioners interested in using approaches based on these findings need to exercise caution as well as excitement about the interesting developments unfolding at an ever increasing rate.     

A post-genomic view of behavioral development and adaptation to the environment

Recent advances in molecular genetics and epigenetics are reviewed that have major implications for the bio-behavioral sciences and for understanding how organisms adapt to their environments at both phylogenetic and ontogenic levels. From a post-genomics perspective, the environment is as crucial as the DNA sequence for constructing the phenotype, and as a source of information in trying to predict phenotypes. The review is organized with respect to four basic processes by which phenotypes adapt to environmental challenges, with an emphasis on the data for humans: (1) developmental plasticity, (2) epigenetic mechanisms, (3) genotype-environment correlations, and (4) gene × environment interactions.     

Evaluation of a social skills program based on social learning theory, implemented in a school setting

Using a sample of 647 Canadian children in kindergarten to Grade 3 (325 boys, 322 girls), the present study evaluated the perceived effectiveness of Skillstreaming (McGinnis & Goldstein, 2003), a widely known social skills program implemented to target the development of four skill sets, i.e., listening, following directions, problem-solving, and knowing when to tell. Results indicated significant postprogram improvements in all skills as well as in ratings of overall prosociality obtained from both classroom teachers and mental health staff, with medium to large effect sizes obtained from teachers' and mental health professionals' ratings, respectively. Additional analyses yielded significant but weak moderator effects of grade and preprogram prosocial functioning for teacher ratings but no consistent moderator effects for children's sex or school location (i.e., urban versus rural) regardless of rater.
