Maternal directiveness, assessed by the mother's use of prescriptives, is correlated with slow vocabulary development. As prescriptives are most often used to redirect a child's attention to a different object or activity, it is hypothesized that attentional regulation underlies this negative relationship. In the present study, twelve mothers were(More)
20 3-month-old infants participated in a nonsocial contingency task immediately following a social interaction with their mothers. A measure of the time the dyads spent in a state of vocal turn-taking predicted individual differences in the infants' subsequent performance on the contingency task. These results parallel the social transfer effects we(More)
3 experiments with 3-month-old infants compared the effects of contingent and noncontingent adult-infant social interactions on subsequent infant-controlled habituation and choice tasks. Infants who experienced a prior noncontingent social interaction tended to adopt response strategies that reduced the density of stimulation during these subsequent(More)
2-year-old children interacted with a robot in a large playroom while their mother sat quietly in the corner. Identical vocalizations from the robot had very different effects on 3 dimensions of the children's behavior when the vocalizations were embedded in reciprocating and nonreciprocating social structures. The reciprocating robot produced (1) more(More)
The effects of a natural aversive stimulus (Hurricane Eloise in 1975) on locus of control and perception of the concept "hurricane" were investigated among 463 fifth graders from Title I schools in two coastal cities along Florida's Panhandle. Although both cities were threatened, only one was hit. Of the 269 Ss in the city hit, 184 had fourth grade locus(More)
Two-, 3-, and 4-year-old children viewed 10 stimulus sets. Each set contained a sample picture (e.g., a dog), a basic-level taxonomic match (e.g., another dog), a thematic match (e.g., a bone), and an irrelevant match (e.g., a pen). The children were asked to choose a match that "goes with" each sample. Sample pictures were either animate entities or(More)
