In this study, self-regulation was investigated in 7- to 10-year-old children using three different measures: (1) parent and child report questionnaires measuring temperamental effortful control, (2) a conflict task assessing efficiency of executive attention, and (3) the mistaken gift paradigm assessing social smiling in response to an undesirable gift. Both efficiency in executive attention and smiling to the undesired gift increased over age. Executive attention was related to both parent-reported temperamental effortful control and smiling, suggesting links between attentional capacities, broad temperament measures, and social situations requiring attentional control.

This study examined individual differences in children's regulation of emotional expression after re- ceiving desirable and undesirable gifts. Effortful control, the ability to suppress a dominant response in favor of a subdominant one, was measured using a battery of be- havioral tasks. Reactions to the gifts were videotaped, and emotional expression was coded. Age predicted effortful control, but not emotional displays. Effortful control predicted similarity of children's displays of positive affect after receiving the two gifts. Specifically, children high in effortful control showed similar amounts of posi- tive affect after receiving the desirable and undesirable gifts, whereas children low in effortful control showed less positive affect after receiving the undesirable gift than after receiving the desirable gift. Results are discussed in terms of temperament and the development of socially appropriate expressive behavior.
