Children's understanding of counterfactual emotions: age differences, individual differences, and the effects of counterfactual-information salience.

The present study investigated developmental trends in the effects of the salience of counterfactual alternatives on judgments of others' counterfactual-thinking-based emotions. We also examined possible correlates of individual differences in the understanding of these emotions. Thirty-four adults and 102 children, 5-8 years of age, were presented scenarios in which characters would be expected to experience regret. In one version of each scenario, the regret-relevant counterfactual alternative was made more salient than was the case with the other version. Adults consistently judged that a character for whom a counterfactual course of events would have resulted in a better outcome would feel worse than a character for whom an alternative course of events would not have resulted in a more positive outcome. The majority of the children's judgments were not affected by the counterfactual alternatives. However, the judgments of the oldest children (the 8-year-olds) were significantly more adult-like in the high-salience than in the low-salience condition. Although the three predictors examined in the present study (verbal ability, working memory capacity, second-order false belief task performance) together accounted for significant variance in performance on the emotions judgment task, no single predictor alone accounted for significant unique variance in performance. The importance of different social cognitive abilities for understanding people's affective responses is discussed.

Sex differences in young children's use of tools in a problem-solving task : The role of object-oriented play.

Three-year-old children were observed in two free-play sessions and participated in a toy-retrieval task, in which only one of six tools could be used to retrieve an out-of-reach toy. Boys engaged in more object-oriented play than girls and were more likely to use tools to retrieve the toy during the baseline tool-use task. All children who did not retrieve the toy during the baseline trials did so after being given a hint, and performance on a transfer-of-training tool-use task approached ceiling levels. This suggests that the sex difference in tool use observed during the baseline phase does not reflect a difference in competency, but rather a sex difference in motivation to interact with objects. Amount of time boys, but not girls, spent in object-oriented play during the free-play sessions predicted performance on the tool-use task. The findings are interpreted in terms of evolutionary theory, consistent with the idea that boys' and girls' play styles evolved to prepare them for adult life in traditional environments.
