Little is known about the acoustic cues infants might use to selectively attend to one talker in the presence of background noise. This study examined the role of talker familiarity as a possible cue. Infants either heard their own mothers (maternal-voice condition) or a different infant's mother (novel-voice condition) repeating isolated words while a female distracter voice spoke fluently in the background. Subsequently, infants heard passages produced by the target voice containing either the familiarized, target words or novel words. Infants in the maternal-voice condition listened significantly longer to the passages containing familiar words; infants in the novel-voice condition showed no preference. These results suggest that infants are able to separate the simultaneous speech of two women when one of the voices is highly familiar to them. However, infants seem to find separating the simultaneous speech of two unfamiliar women extremely difficult. 相似文献

Accountability and cooperation in social dilemmas: The influence of others’ reputational concerns 总被引:1,自引:0,他引:1

The present study examined the assumption that non-anonymous choices in social dilemmas (i.e., choices for which one is accountable)
may influence cooperation, but only to the extent that decision-makers believe that the others will evaluate non-cooperation
negatively. Based on a recent review by Kerr (1999), it was expected that under conditions of accountability, decision-makers
would cooperate more when they believed that the others within the group were also concerned about their social reputation
and therefore were aware of the social norm of cooperation within social dilemmas. As a consequence, it could be expected
that non-cooperation by oneself would be evaluated negatively by those others since they seemed to be aware of what ought
to be done in a social dilemma (i.e., the norm of cooperation). Results confirmed these predictions and, in addition, also
showed that greater willingness to cooperate was associated with stronger feelings of collective concern. The findings are
discussed in terms of recent literature on anonymity effects in social dilemmas.

This study examined whether Project Support, a parenting intervention shown to reduce child conduct problems, also exerts
positive effects on features of psychopathy in children. Participants were 66 families (mothers and children) recruited from
domestic violence shelters who participated in a randomized controlled trial evaluating Project Support. Each family included
at least one child between the ages of 4 and 9 who was exhibiting clinical levels of conduct problems. Families were randomly
assigned to the Project Support intervention condition or to an existing services comparison condition, and they were assessed
on 6 occasions over 20 months, following their departure from the shelter. Children in families in the Project Support condition,
compared with those in the comparison condition, exhibited greater reductions in features of psychopathy. Moreover, the changes
in features of psychopathy remained after accounting for changes in conduct problems. Project Support’s effects on features
of psychopathy were mediated by improvements in mothers’ harsh and inconsistent parenting. These findings on the effects of
an intervention on features of psychopathy are the first from a randomized controlled trial. They inform the debate about
whether features of psychopathy in children are responsive to intervention, and hold important implications for clinical practice. 相似文献

This research examined the relation between mothers' responses to children's questions about interparent conflict and children's adjustment. Participants were 134 mothers and their children (70 boys, 64 girls), aged 7 to 10. In each family, an act of intimate-partner violence (IPV) had recently occurred. Mothers' responses to children's questions about interparent conflict were assessed via a semistructured interview coded to reflect the extent to which the mothers' responses addressed the content of the children's questions. Mothers and children reported on physical IPV. Mothers also reported on interparent conflict, parent-child aggression, and maternal warmth. Children's adjustment was assessed via mothers' and children's reports at two time points 6 months apart. The extent to which mothers' responses addressed the content of the children's questions about interparent conflict was negatively associated with children's adjustment problems, after accounting for the frequency of physical IPV, frequency of interparent conflict, parent-child aggression, and maternal warmth. These associations emerged cross-sectionally and prospectively. However, in those prospective analyses that accounted for children's baseline levels of adjustment, maternal responsiveness was not associated with later children's adjustment problems. 相似文献

We argue that changes in the nature of work in 21st‐century organizations have led to the emergence of star performers—a few individuals who contribute a disproportionate amount of output. We describe how stars negate the long‐held belief that the distribution of individual performance is normal and, instead, suggest an underlying power law distribution. In addition, we offer 9 propositions to guide future empirical research on star performers and an underlying power law distribution of individual performance. We describe how the presence of stars is likely to affect all individual‐, team‐, and firm‐level management theories addressing individual performance directly or indirectly, but focus on specific implications for those addressing human capital, turnover, compensation, downsizing, leadership, teamwork, corporate entrepreneurship, and microfoundations of strategy. In addition, we discuss methodological considerations necessary to carry out our proposed research agenda. Finally, we discuss how a consideration of star performers has important implications for management practice. 相似文献

We examine a distinctive kind of problem for decision theory, involving what we call discontinuity at infinity. Roughly, it arises when an infinite sequence of choices, each apparently sanctioned by plausible principles, converges to a ‘limit choice’ whose utility is much lower than the limit approached by the utilities of the choices in the sequence. We give examples of this phenomenon, focusing on Arntzenius et al.’s Satan’s apple, and give a general characterization of it. In these examples, repeated dominance reasoning (a paradigm of rationality) apparently gives rise to a situation closely analogous to having intransitive preferences (a paradigm of irrationality). Indeed, the agents in these examples are vulnerable to a money pump set-up despite having preferences that exhibit no obvious defect of rationality. We explore several putative solutions to such problems, particularly those that appeal to binding and to deliberative dynamics. We consider the prospects for these solutions, concluding that if they fail, the examples show that money pump arguments are invalid. 相似文献
