The man and the machine: Do children learn from and transmit tool-use knowledge acquired from a robot in ways that are comparable to a human model?

Robots are an increasingly prevalent presence in children's lives. However, little is known about the ways in which children learn from robots and whether they do so in the same way as they learn from humans. To investigate this, we adapted a previously established imitation paradigm centered on inefficient tool use. Children (3- to 6-year-olds; N = 121) were measured on their acquisition and transmission of normative knowledge modeled by a human or a robot. Children were more likely to adopt use of a normative tool and to transmit this knowledge to another when shown how to do so by the human than when shown how to do so by the robot. Older children (5- and 6-year-olds) were less likely than younger children (3- and 4-year-olds) to select the normative tool. Our findings suggest that preschool children are capable of copying and transmitting normative techniques from both human and robot models, albeit at different rates and dependent on age.

Why Do We Hold Mixed Emotions About Racial Out-Groups? A Case for Affect Matching.

A four-wave survey on a national probabilistic sample (N = 17,399) tested novel predictions about how positive and negative contact with racial out-groups predicts warmth and anger toward those groups. Three competing hypotheses were tested: (a) that negative contact will outweigh positive contact when predicting both emotions ("bad is stronger than good"); (b) that negative and positive contact will similarly predict each emotion; and (c) that negative contact will have a disproportionately large association with anger (a negative emotion), whereas positive contact will have a disproportionately large association with warmth (a positive emotion)-a phenomenon known as affect matching. The data revealed clear evidence for affect matching: Negative contact was associated with high levels of anger more than low levels of warmth, whereas positive contact was associated with high levels of warmth more than low levels of anger. Results suggest that positive and negative feelings about out-groups may be tied to qualitatively distinct contact experiences.
