It is becoming increasingly clear that infants’ and toddlers’ temperament may play a central role in their cognitive and linguistic functioning. Research has found, for example, that at 21 months of age, children’s “attentional focus” moderates the extent that environmental distractions prevent them from learning novel words or solving nonlinguistic problems. The purpose of the present investigation was to explore the extent that dimensions of temperament moderate the performance of 15-month-olds on two typical nonlinguistic problemsolving tasks in the presence of environmental distractions. Forty-two 15-month olds visited the lab and were presented two tasks: “feed bear” and “make a rattle.” Infants were familiarized with the two sets of props initially, and then were presented models of desired action sequences. Half the children experienced a distraction during the feed bear task, the remaining were distracted during make a rattle. For each task, four dependent variables were scored: number of target actions performed, variety of target actions performed, longest chain of target actions performed, and number of pairs of actions performed in order. Temperament was measured via maternal report using the Early Child Behavior Questionnaire. Multivariate analyses revealed that children’s performance varied as a function of task [F(5, 24) = 5.42, p = .001]. The distractions also attenuated the effects of the model for both feed bear [univariate Fs(1, 40) = 4.21 to 9.22, ps = .04...
