Chimpanzees demonstrate individual differences in social information use

Studies of transmission biases in social learning have greatly informed our understanding of how behaviour patterns may diffuse through animal populations, yet within-species inter-individual variation in social information use has received little attention and remains poorly understood. We have addressed this question by examining individual performances across multiple experiments with the same population of primates. We compiled a dataset spanning 16 social learning studies (26 experimental conditions) carried out at the same study site over a 12-year period, incorporating a total of 167 chimpanzees. We applied a binary scoring system to code each participant’s performance in each study according to whether they demonstrated evidence of using social information from conspecifics to solve the experimental task or not (Social Information Score—‘SIS’). Bayesian binomial mixed effects models were then used to estimate the extent to which individual differences influenced SIS, together with any effects of sex, rearing history, age, prior involvement in research and task type on SIS. An estimate of repeatability found that approximately half of the variance in SIS was accounted for by individual identity, indicating that individual differences play a critical role in the social learning behaviour of chimpanzees. According to the model that best fit the data, females were, depending on their rearing history, 15–24% more likely to use social information to solve experimental tasks than males. However, there was no strong evidence of an effect of age or research experience, and pedigree records indicated that SIS was not a strongly heritable trait. Our study offers a novel, transferable method for the study of individual differences in social learning.     

Essential Elements for Community Engagement in Evidence-Based Youth Violence Prevention

In the field of youth violence prevention, there has been increasing emphasis on “evidence based” programs and principles shown through scientific research as reaching their intended outcomes. Community mobilization and engagement play a critical role in many evidence‐based programs and strategies, as it takes a concerted effort among a wide range of people within a community to alter behavior and maintain behavioral change. How do concerned individuals and groups within a community engage others within and outside of that community to effectively plan, develop and implement appropriate EB programs as well as evaluate the outcomes and impacts of locally developed programs yet to be proven? The authors discuss five elements essential for community engagement in evidence‐based youth violence prevention based on their work in a university‐community partnership through the Asian/Pacific Islander Youth Violence Prevention Center (API Center), a National Academic Center for Excellence on Youth Violence Prevention Center supported by the Centers for Disease Control and Prevention. They include: (a) aligning EBPs with a community's shared vision and values; (b) establishing an inclusive environment for the planning, implementation and evaluation of EBPs; (c) nurturing collaboration for increased effectiveness and efficacy of EBPs; (d) building adequate leadership and community capacity to develop and sustain EBPs; and (e) building a learning community for evaluation and self‐reflection. The authors propose placing greater emphasis on “evaluative thinking” and organizational capacity for evaluation as we pursue evidence‐based practices for youth violence prevention. This is especially important for ethnic groups for which an evidence base is not well established.     

Primary Care Prescribing Psychologists in the Indian Health Service

Some of the largest health care disparities are those related to services for American Indians and Alaska Natives (AI/ANs), who show significantly greater prevalence for diabetes, coronary heart disease, smoking, obesity, heavy alcohol use, depression, and PTSD than the general population. Given the recognition of the behavioral components of all of these conditions, the Indian Health Service, the federal agency responsible for providing comprehensive health care services to AI/ANs, has been focusing on increasing the integration of behavior health and primary care. One innovation has been to hire prescribing psychologists on primary care teams. This paper describes the role of a prescribing psychologist on three treatment teams at an IHS facility in Montana. Prescribing psychologists in the Indian Health Service can serve as valuable members of comprehensive care teams, providing exceptional wrap-around care for some of our most vulnerable and underserved citizens. This model could be an example of how a prescribing psychologist could contribute to primary care clinics in a variety of other settings.
