The development and flexibility of gaze alternations in bonobos and chimpanzees

Infants’ early gaze alternations are one of their first steps towards a sophisticated understanding of the social world. This ability, to gaze alternate between an object of interest and another individual also attending to that object, has been considered foundational to the development of many complex social‐cognitive abilities, such as theory of mind and language. However, to understand the evolution of these abilities, it is important to identify whether and how gaze alternations are used and develop in our closest living relatives, bonobos (Pan paniscus) and chimpanzees (Pan troglodytes). Here, we evaluated the development of gaze alternations in a large, developmental sample of bonobos (N = 17) and chimpanzees (N = 35). To assess the flexibility of ape gaze alternations, we tested whether they produced gaze alternations when requesting food from a human who was either visually attentive or visually inattentive. Similarly to human infants, both bonobos and chimpanzees produced gaze alternations, and did so more frequently when a human communicative partner was visually attentive. However, unlike humans, who gaze alternate frequently from early in development, chimpanzees did not begin to gaze alternate frequently until adulthood. Bonobos produced very few gaze alternations, regardless of age. Thus, it may be the early emergence of gaze alternations, as opposed gaze alternations themselves, that is derived in the human lineage. The distinctively early emergence of gaze alternations in humans may be a critical underpinning for the development of complex human social‐cognitive abilities.     

Does the dark side of a calling exist? Examining potential negative effects

The present studies examined the potential dark side of perceiving and living a calling with diverse samples of employed adults. In Study 1, living a calling and life meaning were found to suppress the relation between perceiving a calling and life satisfaction, resulting in these variables being significantly, negatively related. This suggests that perceiving a calling may predict decreased well-being when it is not lived out and does not provide meaning. In Study 2, participants living a calling did not experience greater burnout, workaholism, or organizational exploitation. Additionally, counter to hypotheses, living a calling was found to be a significant buffer in the relation of burnout/exploitation and job satisfaction. Specifically, the slope of the relation between living a calling and job satisfaction was more pronounced with individuals experiencing high levels of burnout/exploitation. These findings suggest that living a calling may help individuals in difficult working conditions maintain job satisfaction.     

Examining how aspects of vocational privilege relate to living a calling

The current study examined how aspects of vocational privilege directly – and indirectly via work meaning and career commitment – related to living a calling. With an economically diverse sample of 361 employed adults, both social class and work volition were found to moderately to strongly correlate with work meaning, career commitment, and living a calling. We used a structural equation model and found career commitment and work meaning to significantly predict living a calling and fully mediate the link between work volition and living a calling. Additionally, social class related to work meaning and career commitment via work volition. Findings suggest that the links between social class, work volition, and living a calling may be explained by individuals working in jobs they are committed to and that are meaningful, and that work volition may represent the gateway from social class to the experience of fulfilling work. Implications for practice are discussed.     

Toward accurate inferences of response class membership

In their review of synthesis within the functional analysis (FA) literature, Slaton and Hanley (2018) reported that most synthesized contingency analyses have included multiple topographies of problem behavior in the reinforcement contingency class. This leaves the question of whether one, some, or all forms of problem behavior are sensitive to the synthesized reinforcement contingencies in published analyses. To address this ambiguity, all topographies of problem behavior that were reported by caregivers to co-occur with the most concerning problem behavior were analyzed for 10 participants. We implemented extinction across one or more forms of problem behavior to determine whether all forms reported to co-occur were sensitive to the same synthesized reinforcement contingency. For nine of 10 participants, the most concerning topographies were sensitive to the same synthesized reinforcement contingencies as the less concerning topographies (results were inconclusive for one). Implications for inferring response class membership from single analyses are discussed.     

Perceptions of inferred parental ability through sexually dimorphic facial features

In addition to providing robust cues diagnostic of prospective mates' heritable fitness, various physical features could be similarly utilized in inferring individuals' parental abilities. This study sought to explore how variations in sexually dimorphic facial features inform perceptions of social targets as motivated to provide parental care. American undergraduates (N = 244) viewed a series of 12 total male and female faces manipulated at varying degrees of sex-typicality (i.e., masculinized versus feminized versus unaltered controls) on a within-subjects basis, and rated the perceived motivation of each target to nurture and protect a child using items derived from the Parental Care and Tenderness Scale. Female targets were perceived as more motivated by parental care than male targets, F(1, 240) = 14.86, p < .001, η_p² = 0.058, whereas male targets were perceived as specifically motivated to protect offspring, F(1, 240) = 177.32, p < .001, η_p² = 0.425. Feminized targets were additionally perceived as more motivated by nurturance, though such inferences were apparent for both male and female targets, F(1, 240) = 7.36, p < .001, η_p² = 0.058. Findings represent an understanding of perceivers use of functional heuristics of sexual dimorphism in identifying optimal parents.     

Adolescents' co‐rumination and stress predict affective changes in a daily‐diary paradigm

Co‐rumination has been related to both high quality friendship and depressive symptoms. However, little is known regarding the extent to which co‐rumination may be detrimental, its distinction from rumination and potential gender differences in co‐rumination. This study used a modified version of Rose's Co‐rumination Questionnaire (Rose, 2002) to examine the behaviour of daily co‐rumination with daily stress and negative affect among adolescents. Results demonstrated that co‐rumination did not have a main effect in predicting negative affect, but did evidence a significant interaction with life stress. Additionally, co‐rumination demonstrated incremental utility above that of rumination. Finally, gender differences were not supported. In conclusion, this investigation revealed that co‐rumination exacerbates the effects of life stress and is predictive of increased internalising symptoms.     

Parent ADHD and Evidence-Based Treatment for Their Children: Review and Directions for Future Research

One fourth to one half of parents of children with attention-deficit/hyperactivity disorder (ADHD) have ADHD themselves, complicating delivery of evidence-based child behavioral and pharmacological treatments. In this article, we review the literature examining the relation between parent ADHD and outcomes following behavioral and pharmacological treatments for children with ADHD. We also review research that has incorporated treatment of parent ADHD (either alone or in combination with child treatment) with the goal of improving parenting and child outcomes. Finally, we offer recommendations for future research on the relation between parent ADHD and evidence-based treatment outcomes for their children, with the purpose of advancing the science and informing clinical care of these families.     

What is Working,What is Not,and What We Need to Know: a Meta-Analytic Review of Business Ethics Instruction

Requirements for business ethics education and organizational ethics trainings mark an important step in encouraging ethical behavior among business students and professionals. However, the lack of specificity in these guidelines as to how, what, and where business ethics should be taught has led to stark differences in approaches and content. The present effort uses meta-analytic procedures to examine the effectiveness of current approaches across organizational ethics trainings and business school courses. to provide practical suggestions for business ethics interventions and research. Thus, the primary questions driving this research are as follows: (1) what course characteristics moderate the effectiveness of ethics instruction?, and (2) have ethics education and training efforts improved? Findings suggest that professional, focused, and workshop-based training programs are especially effective for improving business ethics. However, results also reveal considerable problems with many of the criteria used to evaluate the effectiveness of business ethics interventions. Practical suggestions for course design and evaluation in business ethics efforts are discussed along with future research needs.
