Behavioral and environmental correlates of infant abuse in group- living pigtail macaques

The present study investigated the context of occurrence of infant abuse and the behavior of abusive mothers and their infants in pigtail macaques (Macaca nemestrina). Subjects were 8 abusive mothers with their infants and 8 control mother-infant pairs living in 3 captive social groups. The most common forms of abuse were infant crushing and dragging and the most common context of occurrence was social stress. Severe and mild abuse differed in the frequency but not in the type of abuse patterns. Abusive mothers had controlling parenting styles relative to nonabusive mothers, and abused infants played at a later age and less frequently than controls. This study replicates previous findings on the parenting styles of abusive macaque mothers and provides new evidence on the context of occurrence of abuse and its consequences for infant health and social development.     

Mothers', fathers' and children's perceptions of parents' expectations about children's family obligations in nine countries

Children's family obligations involve assistance and respect that children are expected to provide to immediate and extended family members and reflect beliefs related to family life that may differ across cultural groups. Mothers, fathers and children (N = 1432 families) in 13 cultural groups in 9 countries (China, Colombia, Italy, Jordan, Kenya, Philippines, Sweden, Thailand and United States) reported on their expectations regarding children's family obligations and parenting attitudes and behaviours. Within families, mothers and fathers had more concordant expectations regarding children's family obligations than did parents and children. Parenting behaviours that were warmer, less neglectful and more controlling as well as parenting attitudes that were more authoritarian were related to higher expectations regarding children's family obligations between families within cultures as well as between cultures. These international findings advance understanding of children's family obligations by contextualising them both within families and across a number of diverse cultural groups in 9 countries.     

Sensitizing Potential Jurors to Variations in Eyewitness Evidence Quality Using Counterfactual Thinking

Jurors often have difficulty evaluating eyewitness testimony. Counterfactual thinking is a type of mental simulation that informs causal inference. Encouraging jurors to think counterfactually about eyewitness factors may sensitize them to these factors' causal influence on eyewitness identification and testimony accuracy, improving their overall judgments (such as verdicts). One hundred twenty‐one undergraduate participants were randomly assigned to read a scenario containing either high‐quality or low‐quality eyewitness evidence and to evaluate eyewitness factors adopting either their default or a counterfactual mindset via a question‐order manipulation. Logistic regressions and analyses of variance revealed that a counterfactual mindset lowered perceptions of eyewitness accuracy and guilty verdicts (compared with the default mindset) when the evidence was poor; a counterfactual mindset, however, did not increase perceptions of accuracy and guilty verdicts when evidence was strong. We discuss possible mechanisms underlying these effects and identify several potential avenues for future research.Copyright © 2016 John Wiley & Sons, Ltd.     

Chaos,danger, and maternal parenting in families: Links with adolescent adjustment in low‐ and middle‐income countries

The current longitudinal study is the first comparative investigation across low‐ and middle‐income countries (LMICs) to test the hypothesis that harsher and less affectionate maternal parenting (child age 14 years, on average) statistically mediates the prediction from prior household chaos and neighborhood danger (at 13 years) to subsequent adolescent maladjustment (externalizing, internalizing, and school performance problems at 15 years). The sample included 511 urban families in six LMICs: China, Colombia, Jordan, Kenya, the Philippines, and Thailand. Multigroup structural equation modeling showed consistent associations between chaos, danger, affectionate and harsh parenting, and adolescent adjustment problems. There was some support for the hypothesis, with nearly all countries showing a modest indirect effect of maternal hostility (but not affection) for adolescent externalizing, internalizing, and scholastic problems. Results provide further evidence that chaotic home and dangerous neighborhood environments increase risk for adolescent maladjustment in LMIC contexts, via harsher maternal parenting.     

Whose hand is this? Differential responses of right and left extrastriate body areas to visual images of self and others’ hands

The extrastriate body area (EBA) is involved in perception of human bodies and nonfacial body parts, but its role in representing body identity is not clear. Here, we used on-line high-frequency repetitive transcranial magnetic stimulation (rTMS) to test the role of EBA in self–other distinction. In Experiments 1 and 2 we compared rTMS of right EBA with stimulation of left ventral premotor cortex (vPM), whereas in Experiment 3 we compared stimulation of right and left EBA. RTMS was applied during a hand laterality task in which self or others’ hand images were presented in first- versus third-person view (Experiments 1 and 3), or while participants had to explicitly recognize their own hands (Experiment 2) presented in first- versus third-person view. Experiment 1 showed that right EBA stimulation selectively speeded judgments on others’ hands, whereas no effect of left vPM stimulation was found. Experiment 2 did not reveal any effect of rTMS. Experiment 3 confirmed faster responses on others’ hands while stimulating right EBA and also showed an advantage when judging self with respect to others’ hands during stimulation of left EBA. These results would demonstrate that EBA responds to morphological features of human body contributing to identity processing.     

Toward a Life Course Framework for Studying Vulnerability

Interest in the study of vulnerability has experienced impressive growth across various disciplines. To contribute to this major but scattered development in the study of vulnerability, this article argues for a multidisciplinary life-course framework. This framework promotes a systemic and dynamic perspective focused on three complementary research directions: multidimensional, multilevel, and multidirectional. On the basis of this life course perspective, the authors also propose a definition of vulnerability as a dynamic process of stress and resources across various domains of life (i.e., work, family, health, migration, etc.), levels (i.e., person, group, collective), and time (i.e., long-term processes).     

Misleading Norms and Vulnerability in the Life Course: Definition and Illustrations

This review paper investigates the potentially misleading effect of some social norms on life trajectories. Conformity to some gender norms related to the division of paid and family work becomes counterproductive for individuals who experience turning points in their life along the way. We present various empirical results mainly drawn from the Swiss National Centre of Competence in Research LIVES where conformity to social norms has detrimental effects on life trajectories. We conclude by stressing that the sensitizing concept of misleading norms contributes to a better understanding of vulnerability across the life course.     

Drawing with oblique coordinates: on a single case

We describe a patient with right hemisphere damage affected by mild left visuo-spatial neglect and constructional apraxia. During the rehabilitation, he failed to draw a draught-board using horizontal and vertical trajectories, but he performed it successfully using oblique trajectories. These observations suggested an impairment of vertical/horizontal spatial coordinates system. In copying tasks including figure elements in different orientations he drew more accurately components in oblique orientation, whereas failed to reproduce components in horizontal orientation. The patient performed visuospatial perceptual and perceptual-imaginative tasks successfully. From these findings, it is possible to suggest that the oblique coordinate system of reference operates independently of vertical and horizontal coordinate systems in building a complex figure and that, therefore, cardinal orientation do not constitute a reference norm to define oblique orientation, as previously suggested.
