Rapid cognitive flexibility of rhesus macaques performing psychophysical task-switching

Three rhesus monkeys (Macaca mulatta) performed a simultaneous chaining task in which stimuli had to be sorted according to their visual properties. Each stimulus could vary independently along two dimensions (luminosity and radius), and a cue indicating which dimension to sort by was random trial to trial. These rapid and unpredictable changes constitute a task-switching paradigm, in which subjects must encode task demands and shift to whichever task-set is presently activated. In contrast to the widely reported task-switching delay observed in human studies, our subjects show no appreciable reduction in reaction times following a switch in the task requirements. Also, in contrast to the results of studies on human subjects, monkeys experienced enduring interference from trial-irrelevant stimulus features, even after exhaustive training. These results are consistent with a small but growing body of evidence that task-switching in rhesus macaques differs in basic ways from the pattern of behavior reported in studies of human cognition. Given the importance of task-switching paradigms in cognitive and clinical assessment, and the frequency with which corresponding animal models rely on non-human primates, understanding these differences in behavior is essential to the comparative study of cognitive impairment.     

Imitation and Creativity: Beneficial Effects of Propulsion Strategies and Specificity

Prior studies examining imitation of exemplar solutions have produced a mixed pattern of findings with some studies indicating that exemplar imitation contributes to creative problem‐solving and other studies indicating that it may inhibit creative problem‐solving. In the present effort, it is argued that the effects of exemplar imitation on creative problem‐solving depend on the strategies people use when working with exemplars. In the present study, people were asked to provide advertising campaigns in response to a marketing problem. Prior to starting work on this problem, manipulations were made in exemplar content. Imitation strategies used in problem‐solving, for example, forward incrementation, and redefinition, were assessed. It was found that imitation strategies were strongly related to the production of higher quality, more original, and more elegant advertising campaigns. Moreover, use of these strategies was facilitated when more specific information was presented in exemplar solutions. The implications of these findings for understanding the role of imitation in creative problem‐solving are discussed.     

Associations between work family conflict,emotional exhaustion,musculoskeletal pain,and gastrointestinal problems in a sample of business travelers

The aim of the study was to examine the associations among work‐family conflict (WFC), emotional exhaustion, musculoskeletal (MS) pain, and gastrointestinal problems on a sample of business travelers (n = 2,093). An additional aim was to examine differences in the mentioned relationships among three traveler groups: commuters, national travelers, and international travelers. The study was conducted in a large Norwegian oil and gas company, and the company's business travel database was utilized to examine business travel. Structural equation modeling (SEM) revealed significant relations between WFC and emotional exhaustion and between emotional exhaustion and health problems. Contrary to the expectations, no direct association was found between WFC and health problems. However, we found that emotional exhaustion mediated the relation between WFC and health outcomes. The results from multi‐group analysis revealed that associations among WFC, emotional exhaustion, and health‐outcomes showed a similar pattern for commuters, national travelers, and international travelers. However, the association between emotional exhaustion and MS pain proved to be significantly stronger for the commuter group compared to the national and international travel groups. Practical implications and the consequences of these findings for future research are discussed.     

Coping responses in the midst of terror: The July 22 terror attack at Utøya Island in Norway

This study examined the peri‐trauma coping responses of 325 survivors, mostly youth, after the July 22, 2011 terror attack on Utøya Island in Norway. The aim was to understand peri‐trauma coping responses and their relation to subsequent post‐traumatic stress (PTS) reactions. Respondents were interviewed face‐to‐face 4–5 months after the shooting, and most were interviewed at their homes. Peri‐trauma coping was assessed using ten selected items from the “How I Cope Under Pressure Scale” (HICUPS), covering the dimensions of problem solving, positive cognitive restructuring, avoidance, support seeking, seeking understanding, and religious coping. PTS reactions were assessed with the UCLA PTSD Reaction Index. The participants reported using a wide variety of coping strategies. Problem solving, positive cognitive restructuring, and seeking understanding strategies were reported most often. Men reported using more problem‐solving strategies, whereas women reported more emotion‐focused strategies. There were no significant associations between age and the use of coping strategies. Problem solving and positive cognitive restructuring were significantly associated with fewer PTS reactions. The results are discussed in light of previous research and may help to inform early intervention efforts for survivors of traumatic events.     

Does the Animal Fun program improve motor performance in children aged 4–6 years?

The Animal Fun program was designed to enhance the motor ability of young children by imitating the movements of animals in a fun, inclusive setting. The efficacy of this program was investigated through a randomized controlled trial using a multivariate nested cohort design. Pre-intervention scores were recorded for 511 children aged 4.83 years to 6.17 years (M = 5.42 years, SD = 3.58 months). Six control and six intervention schools were compared 6 months later following the intervention, and then again at 18 months after the initial testing when the children were in their first school year. Changes in motor performance were examined using the Bruininks-Oseretsky Test of Motor Proficiency short form. Data were analyzed using multi-level-mixed effects linear regression. A significant Condition × Time interaction was found, F(2, 1219) = 3.35, p = .035, demonstrating that only the intervention group showed an improvement in motor ability. A significant Sex × Time interaction was also found, F(2, 1219) = 3.84, p = .022, with boys improving over time, but not girls. These findings have important implications for the efficacy of early intervention of motor skills and understanding the differences in motor performance between boys and girls.     

Simultaneous perception of both interpretations of ambiguous figures

When viewing ambiguous figures like the classic duck/rabbit, people alternately perceive one interpretation and then the other, but not both interpretations at once. When two identical ambiguous figures appear together, the majority of observers perceive them as identical, and they typically alternate in unison. Just as most observers cannot see a single figure as both a duck and a rabbit, most cannot see one figure in a pair as a duck and the other as a rabbit even though the two figures and their features are spatially distinct. Is this inability to see both interpretations an inherent limitation of the visual system or is it just due to differences in top-down processing? We show that a simple prompt immediately allows people to see both interpretations, to their own surprise.     

Risky Behavior in Affluent Youth: Examining the Co-occurrence and Consequences of Multiple Problem Behaviors

Children of affluent parents are often excluded in psychological research as they are considered to be at “low risk”; however, research is beginning to suggest that this previously under-studied population may be at risk for developing multiple problem behaviors, including substance use and externalizing problems. The current study aimed to extend the application of Problem Behavior Theory (PBT) to a sample of affluent adolescents by examining the extent to which these behaviors co-occurred and were associated with negative outcomes. Data were collected from 1,147 high school students living in an affluent community via anonymous questionnaires regarding their engagement in various problem behaviors. PBT was supported in this sample, and youth who engaged in multiple problem behaviors reported experiencing more negative outcomes than youth who did not engage in these behaviors. The findings of this study support the generalizability of PBT and also highlight the importance of continuing to study affluent youth in addition to traditionally high-risk populations.     

Psychological Contracts and Counterproductive Work Behaviors: Employee Responses to Transactional and Relational Breach

Purpose  

This study extends the research on counterproductive work behavior (CWB) by examining the psychological contract breaches that trigger employee CWB. Specifically, we explored the relationship between transactional and relational contract breach and five forms of CWB (abuse, production deviance, sabotage, theft, and withdrawal). Further, we considered the role of situational and individual factors that mitigate CWB engagement and examined the moderating effects of organizational policies meant to deter CWB and personality (conscientiousness, agreeableness, and emotional stability).
