The Arena System: a novel shared touch-panel apparatus for the study of chimpanzee social interaction and cognition

We report on the development of a novel shared touch-panel apparatus for examining a diverse range of topics in great ape social cognition and interaction. Our apparatus—named the Arena System—is composed of a single multitouch monitor that spans across two separate testing booths, so that individuals situated in each booth have tactile access to half of the monitor and visual access to the whole monitor. Additional components of the system include a smart-film barrier able to restrict visual access between the booths, as well as two automated feeding devices that dispense food rewards to the subjects. The touch-panel, smart-film, and feeders are controlled by a PC that is also responsible for running the experimental tasks. We present data from a pilot behavioral game theory study with two chimpanzees in order to illustrate the efficacy of our method, and we suggest applications for a range of topics including animal social learning, coordination, and behavioral economics. The system enables fully automated experimental procedures, which means that no human participation is needed to run the tasks. The novel use of a touch-panel in a social setting allows for a finer degree of data resolution than do the traditional experimental apparatuses used in prior studies on great ape social interaction.     

Event centrality and posttraumatic outcomes in the context of pervasive violence: a study of teachers in El Salvador

It is well established that the importance assigned to a trauma can affect one's recovery and psychological health in numerous ways. Event centrality is an increasingly popular construct that captures the tendency among survivors to reevaluate and possibly accommodate their worldviews posttrauma. The centrality given to trauma appears to serve as a “double-edged sword” in that this construct might factor prominently in both posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG). Focusing on 257 violence-exposed teachers from educational departments throughout El Salvador, we examined whether the centrality assigned by the teachers to stressful life events uniquely predicted both PTSD symptomatology and PTG. Results revealed that event centrality was positively related to both PTSD and PTG, even when controlling for demographic factors, violence exposure, and depression. In addition, PTSD symptomatology and PTG were not associated with one another in this sample. In summary, these findings support the role of event centrality as a contributing factor for PTSD and PTG among persons exposed to pervasive trauma.     

The Impact of Youth Risk on Mentoring Relationship Quality: Do Mentor Characteristics Matter?

Although mentoring is a widely used intervention strategy, effect sizes for at‐risk youth remain modest. Research is therefore needed to maximize the impact of mentoring for at‐risk youth who might struggle to benefit from mentoring relationships. This study tested the hypothesis that different types of youth risk would have a negative impact on mentoring relationship quality and duration and explored whether mentor characteristics exacerbated or mitigated these negative effects. Results showed that elevated environmental stress at a youth's home and/or school predicted shorter match duration, and elevated rates of youth behavioral problems, such as poor academic performance or misconduct, predicted greater youth dissatisfaction and less positive mentor perceptions of relationship quality. Mentors with greater self‐efficacy and more previous involvement with youth in their communities were able to buffer the negative effects of environmental stress on match duration. Similarly, mentors' previous involvement with youth buffered the negative effects of youth behavioral problems on mentor perceptions of relationship quality. Findings have important implications for the matching of mentors and at‐risk youth in a way that improves mentoring outcomes.     

Midwives on the Margins: Stigma Management among Out-of-Hospital Midwives

Out-of-hospital midwives’ occupational practices can be interpreted as “dirty work” because of their responsibility to touch women’s genitals and the perceived danger of providing healthcare separate from a hospital. Thus, midwives experience prejudice in their interactions with healthcare providers and the public alike. Using 30 interviews with out-of-hospital midwives, this research explores sources and forms of prejudice and techniques with which participants managed their stigmatized professional identity. Specifically, midwives used strategies of information control, including controlling disclosure and controlling interactions. While previous research documents such techniques, I add theoretical complexity by expanding our knowledge on concealable stigmatized identities.     

Bridging team faultlines by combining task role assignment and goal structure strategies

This study tests whether the detrimental effects of strong diversity faultlines on team performance can be counteracted by combining 2 managerial strategies: task role crosscutting and superordinate goals. We conducted a 2 (crosscut vs. aligned roles) × 2 (superordinate vs. subgroup goals) experimental study. Seventy-two 4-person teams with faultlines stemming from gender and educational major performed a complex decision-making task. The results show that teams with crosscut roles perform better when they are assigned a superordinate goal than a subgroup goal, whereas teams with aligned roles are not affected by goal manipulations. This effect is mediated by elaboration of task-relevant information. Implications for theory and management of team faultlines are discussed.     

Increasing outgroup trust,reducing infrahumanization,and enhancing future contact intentions via imagined intergroup contact

The present study was designed to test whether imagined intergroup contact (Crisp & Turner, 2009) affects attributions of human emotions to outgroup members and positive behavioral intentions toward the outgroup via increased outgroup trust. Italian fourth-graders took part in a three-week intervention, where they were asked to imagine meeting an unknown immigrant child in various social settings. One week after the last session, they were administered the dependent measures. Results revealed an indirect effect of imagined contact on both behavioral intentions and attributions of uniquely human emotions to outgroup members via outgroup trust. The theoretical and practical implications are discussed, and an integration of the imagined contact and infrahumanization literature is suggested.     

Traditional Machismo and Caballerismo as Correlates of Posttraumatic Stress Disorder,Psychological Distress,and Relationship Satisfaction in Hispanic Veterans

An online survey was used to examine 45 Hispanic male veterans’ traditional machismo and caballerismo as correlates of posttraumatic stress disorder (PTSD), psychological distress, and relationship satisfaction. Higher traditional machismo was associated with higher PTSD severity and distress and lower relationship satisfaction. Psychometric properties of the Traditional Machismo and Caballerismo Scale were explored. Se utilizó una encuesta en línea para examinar el machismo y el caballerismo tradicionales de 45 veteranos hispanos varones, y su correlación con el trastorno de estrés post‐traumático (PTSD, por sus siglas en inglés), la angustia psicológica y la satisfacción en sus relaciones. Un mayor nivel de machismo tradicional se asoció con una mayor severidad del PTSD, así como con angustia y una menor satisfacción en las relaciones. Se exploraron las propiedades psicométricas de la Escala de Machismo y Caballerismo Tradicionales.     

Do infants bind mental states to agents?

Recent findings suggest that infants understand others’ preferential choice and can use the perspectives and beliefs of others to interpret their actions. The standard interpretation in the field is that infants understand preferential choice as a dispositional state of the agent. It is possible, however, that these social situations trigger the acquisition of more general, not person-specific knowledge. In a looking-time study we showed an Agent A demonstrating a choice, that only could have been interpreted as preferential based on the perspective (and thus the belief) of the agent, not the observer. Then we introduced a new agent (Agent B), who chose consistently or inconsistently with Agent A; also varying whether Agent B was an adult or a child. Results show that infants expected Agent B (both the adult and the child) to choose as Agent A, but only in the condition where according to Agent A’s knowledge two objects were present in familiarization(confirming previous evidence on the importance of contrastive choice). We interpret these results in the following way: (1) infants do not encode the perspectives of other agents as person-specific sources of knowledge and (2) they learn about the object, rather than the agent’s disposition towards that object. We propose that early theory of mind processes lack the binding of belief content to the belief holder. However, such limitation may in fact serve an important function, allowing infants to acquire information through the perspectives of others in the form of universal access to general information.
