Asymmetries in the production of self-directed behavior by chimpanzees and gorillas during a computerized cognitive test

Self-directed behaviors (SDBs) are a commonly used behavioral indicator of arousal in nonhuman primates. Experimental manipulations, designed to increase arousal and uncertainty, have been used to elicit SDB production in primates. Beyond measuring rates of SDB production, researchers have also recorded their lateralized production by primates, thought to reflect laterality of hemispheric brain control and response to emotion. Although a handful of such studies exist, all have been conducted with chimpanzees. Expanding on this line of inquiry, we tested both chimpanzees (N = 3) and gorillas (N = 3) in a serial learning task presented on a touchscreen interface that incorporated both EASY (two-item list) and HARD (four-item list) versions of the task. Although SDB production by the apes did not differ across the two levels of task complexity, both species produced higher rates of SDB when they made an error, regardless of task difficulty. Furthermore, the apes made more SDB with the left hand—directed to the right side of their body (contralateral SDB) and left side of their body (ipsilateral SDB)—when they made an incorrect response. There was no difference in the rate of SDB produced with the right hand across correct compared to incorrect trials. The apes’ responses reflect previous reports that show humans are quicker at selecting negative emotional stimuli when using their left, compared to their right, hand (the reverse is true for positive stimuli). However, previous work has shown that chimpanzees are more likely to produce (contralateral) SDB with their right hand when aroused and so we discuss our results in relation to these findings and consider how they relate to the ‘right hemisphere’ and ‘valence’ models of emotional processing in apes.     

Stress-Induced Cardiomyopathy and Psychological Wellbeing 1 Year After an Acute Event

Stress cardiomyopathy (SCM) typically presents similar symptoms to acute myocardial infarction (AMI). However, these symptoms differ when it comes to a transient and completely reversible myocardial dysfunction, which is frequently precipitated by acute stressful events, occurring in the absence of plaque rupture and coronary thrombosis. The purpose of this study was to investigate health-related quality of life (HRQL) and emotional burden subsequent to cardiac events in SCM patients. Thirty-seven SCM patients were compared with 37 matched AMI patients. All selected patients were assessed for HRQL and psychological distress at baseline and 1-year after the acute event. After controlling for covariates, scores on the Psychological General Well Being Index indicated that depressed mood had increased in both groups, but the increase for SCM patients was greater than for AMI patients. The AMI group displayed greater decreases than the SCM in physical quality of life and in total cardiac-related health quality of life. The percentage of patients with psychological distress increased significantly more in the SCM group than in the AMI group, and it made no difference whether the triggering event was emotional or physical. Our results suggest that, despite the more favorable medical prognosis of SCM patients, their cardiac condition being transient and resolving completely in few weeks, the psychological impact associated with their condition is more negative 1 year later than in the case of AMI patients whose medical prognosis is less favorable, and this difference is independent of type of trigger event.     

Compassionate Conservatives? Evangelicals,Economic Conservatism,and National Identity

In the United States, white evangelicals are more economically conservative than other Americans. It is commonly assumed that white evangelicals oppose redistributive social policies because of their individualistic theology. Yet Canadian evangelicals are just as supportive of redistributive social policy as other Canadians, even though they share the same tools of conservative Protestant theology. To solve this puzzle, I use multi‐sited ethnography to compare how two evangelical congregations in the United States and Canada talked about poverty and the role of government. In both countries, evangelicals made sense of their religious responsibilities to “the poor” by reference to national identity. Evangelicals used their theological tools differently in the United States and Canada because different visions of national solidarity served as cultural anchors for religious discourse about poverty. To understand the political and civic effects of religion, scholars need to consider the varied ways that religious groups imagine national community within religious practice.     

Fifth-Grade Children’s Daily Experiences of Peer Victimization and Negative Emotions: Moderating Effects of Sex and Peer Rejection

This study examined the relations of fifth-grade children’s (181 boys and girls) daily experiences of peer victimization with their daily negative emotions. Children completed daily reports of peer victimization and negative emotions (sadness, anger, embarrassment, and nervousness) on up to eight school days. The daily peer victimization checklist was best represented by five factors: physical victimization, verbal victimization, social manipulation, property attacks, and social rebuff. All five types were associated with increased negative daily emotions, and several types were independently linked to increased daily negative emotions, particularly physical victimization. Girls demonstrated greater emotional reactivity in sadness to social manipulation than did boys, and higher levels of peer rejection were linked to greater emotional reactivity to multiple types of victimization. Sex and peer rejection also interacted, such that greater rejection was a stronger indicator of emotional reactivity to victimization in boys than in girls.     

Proactive Responding to Anticipated Discrimination Based on Chronic Illness: Double-Edged Sword?

Purpose

Proactive strategies for avoiding stigmatization may prevent work-related discrimination (Singletary and Hebl J Appl Psychol 94:797–805, 2009), yet these strategies may also cause strain in the stigmatized. We tested a model in which previous workplace discrimination experiences and anticipated future workplace discrimination related to proactive responses (compensatory behaviors and concealing behaviors), which, in turn, related to job tension.

Design/Methodology/Approach

Survey data were obtained from 332 workers with chronic illnesses. Structural equation modeling was used to test the proposed relationships.

Findings

Perceived previous discrimination directly related to anticipated future discrimination and indirectly related to compensatory and concealing behaviors. Anticipated discrimination directly related to compensatory and concealing behaviors, and indirectly related to job tension through compensatory behaviors. Compensatory behaviors were, but concealing behaviors were not, related to job tension.

Implications

Workers with chronic illness should be educated on ways to mitigate the negative effects of compensatory behaviors, including ensuring adequate opportunities to replenish resources. Organizations should provide assistance to these workers through Employee Assistance Programs or other types of job counseling. Organization leaders and supervisors have a responsibility to build an environment of acceptance for those with chronic illness in order to reduce potential discrimination.

Originality/Value

While proactive strategies are effective in reducing negative outcomes of stigmatization, little research has explored their potential downsides. We highlight the “double-edged sword” nature of compensatory behaviors. In addition, while a large proportion of U.S. workers are managing chronic illness, this population is understudied.     

Renegotiating Identity: A Phenomenological Investigation of the College Transition for Former High School Athletes No Longer Engaged in Varsity Competition

A breadth of research has examined the influence of athletic identity on college student-athlete experiences (e.g., Harrison et al., 2011; Lally & Kerr, 2005). In addition, scholars have investigated role transition among college student-athletes at the end of their eligibility (e.g., Taylor & Ogilvie, 2001; Wylleman & Lavallee, 2004). However, despite that 97% of high school athletes will not participate collegiately (National Collegiate Athletic Association, 2016), little attention has been paid to identity renegotiation among college students who discontinued sport participation after high school. The present study was designed to fill this gap by addressing the impact of sport disengagement on former high school athletes no longer engaged in varsity competition during the first year of college. In-depth, semi-structured interviews were conducted with 13 university freshmen at three time points: the end of the first month, the end of the first semester, and the end of the first year. Commonalities among participants’ transition experiences were identified. Findings yielded three major themes, role transition, identity renegotiation, and reflection and projection, each being facilitated by the building of camaraderie. Findings deepen current understanding of role transition and identity renegotiation and offer directions for future research related to sense of self during the college transition.     

Promoting positive body image among university students: A collaborative pilot study

The purpose of the present study was to pilot a prevention program designed to promote positive body image among university students. Thirty-seven undergraduate students from three Canadian universities were recruited to participate in the study. They were selected from a pool of students enrolled in a peer health education program facilitated by the university-based health promotion staff. Borrowing from the tenets of the non-specific vulnerability stressor model and the disease-specific social cognitive theory, the intervention focused on media literacy, self-esteem enhancement strategies, stress management skills and ways to recognize healthy versus unhealthy relationships. Separate ANOVAs revealed that participants reported significant improvements in body satisfaction and reductions in the internalization of media stereotypes between the baseline and post-program period. The program received a favorable response from the participating students, who appreciated the face-to-face format of the intervention, and from the university staff who expressed interest in embedding the strategies into their routine peer mentoring training activities. Limitations of the study and suggestions for future research are discussed.     

Relative Clause Gap-Filling in Children with Specific Language Impairment

Children with Specific Language Impairment (SLI) have been observed to have production and perception difficulties with sentences containing long-distance dependencies, but it is unclear whether this is due to impairment in grammatical knowledge or in processing mechanisms. The current study addressed this issue by examining automatic on-line gap-filling in relative clauses, as well as off-line comprehension of the same stimulus sentences. As predicted by both knowledge impairment and processing impairment models, SLI children showed lack of immediate gap-filling after the relative clause verb, in comparison to a control group of typically developing children. However, on the off-line measure of comprehension of the same stimuli sentences, SLI children and TD children did not differ qualitatively. This finding is incompatible with knowledge impairment. We interpret the results to show that SLI children have impaired processing mechanisms (such as temporally delayed gap-filling) but are not impaired in their grammatical knowledge.     

Observational learning of tool use in children: Investigating cultural spread through diffusion chains and learning mechanisms through ghost displays

In the first of two experiments, we demonstrate the spread of a novel form of tool use across 20 “cultural generations” of child-to-child transmission. An experimentally seeded technique spread with 100% fidelity along twice as many “generations” as has been investigated in recent exploratory “diffusion” experiments of this type. This contrasted with only a single child discovering the technique spontaneously in a comparable group tested individually without any model. This study accordingly documents children’s social learning of tool use on a new, population-level scale that characterizes real-world cultural phenomena. In a second experiment, underlying social learning processes were investigated with a focus on the contrast between imitation (defined as copying actions) and emulation (defined as learning from the results of actions only). In two different “ghost” conditions, children were presented with the task used in the first experiment but now operated without sight of an agent performing the task, thereby presenting only the information used in emulation. Children in ghost conditions were less successful than those who had watched a model in action and showed variable matching to what they had seen. These findings suggest the importance of observational learning of complex tool use through imitation rather than only through emulation. Results of the two experiments are compared with those of similar experiments conducted previously with chimpanzees and are discussed in relation to the wider perspective of human culture and the influence of task complexity on social learning.
