How do you think she feels? Vulnerability in empathy and the role of attention in school‐aged children born extremely preterm

The aim of this study was to examine empathic competence in children born extremely preterm (EP, <28 weeks) given vulnerabilities in social relationships. Empathy in typically developing children is mediated by executive functions. Executive functioning is also impaired in preterm children. Of particular interest in this study are the attentional components of executive functioning as mediators of empathic development. Thirty‐two 7‐year‐old EP children and 40 age‐matched term children participated in the Project K.I.D.S program and completed the Kids Empathy Development Scale (KEDS), Wechsler Intelligence Scale for Children (WISC‐IV), and Test of Everyday Attention for Children (TEA‐Ch). Children born extremely preterm exhibited poorer performance on all measures. The mediating role of attention in empathy competence was not supported by mediation modelling when FSIQ was controlled. As predicted, the EP group showed weaker empathic development relative to typically developing children. They also showed poorer attentional abilities. However, the effect of preterm birth on empathy was not mediated by executive‐level attention. The cognitive mechanisms underpinning poor empathy competence in EP children remain unclear. Future research needs to examine the role of inhibition, social–emotional recognition, and regulation.     

Gender stereotypes underlie child custody decisions

Using hypothetical divorce cases we examine the role of gender stereotypes in decisions about child custody. Good mothers received greater custody allocations than did good fathers across a tightly matched pair of vignettes in three culturally distinct samples: Argentina, Brazil, and the United States (Study 1). Two follow-up studies indicated that the warmth dimension of stereotype content partly accounted for the asymmetry in custody awards: The proportion of maternal-primary custody was predicted by the tendency to ascribe warmth-related traits—such as friendliness, generosity, or trustworthiness—to mothers (Study 2) and associate them with female over male nouns (Study 3). We also found that endorsing shared custody mitigated the asymmetry in custody awards documented in our studies. Together, these results highlight the interplay of stereotyped attitudes and egalitarian commitments in the context of judicial decisions about child custody.     

Aggregating preference rankings: An AHP-based approach

The problem considered here involves the selection of an alternative by a group of decision makers in a context that involves the aggregating of votes from a preferential ballot. A popular approach for solving such problems is the well-known weighting problem formulation. However, with such a formulation two issues become of critical importance: (a) the weights should reflect the decision-making group's belief on the importance of each rank position and (b) the weights should accord each alternative a fair (if not its best) assessment. Many researchers have studied this problem and proposed various solution strategies. None of these strategies, however, appears to have adequately addressed both issues. The objective of this research is to develop a group decision-making model that solves the problem in a manner that adequately addresses the two critical issues identified, as well as allows for sensitivity analysis and is fairly robust with respect to the various paradoxes identified in voting systems.
