Three experiments examined peer imitation with 14- to 18-month-old infants. In Experiment 1, infants saw a trained 14-month-old ("expert peer") perform specific actions on 5 objects. Imitation from memory was tested after a 5-min delay. In Experiment 2, the infants observed an expert peer in the laboratory, and retention and imitation were tested i...

Sixty-eight 3-year-olds received a standard appearance-reality task along with either a trick task, in which the appearance question was placed in the context of a deceptive game, or a reduced information processing task, in which a dual object (e.g., a sponge-rock) was presented along with an object that matched the dual object's identity (a spong...

At what age and in what ways do children distinguish deductive and inductive problems? In Experiment 1, students from kindergarten and from Grades 2, 4, and 6 were presented with deductive or inductive inference problems and asked to draw an inference and rate their confidence. By 4th grade, confidence ratings for deductive problems were higher tha...

This study evaluated a social process model describing how aggression and withdrawal lead to negative social self-perceptions. The model posited both direct (i.e., cognitions associated with withdrawal) and indirect (i.e., mediations of negative peer status and peer experiences) influences. Eight- to 10-year-old children (n = 793) completed peer as...

A longitudinal study investigated the relation between infant expectations and reaction time (RT) and childhood IQ and RT. Measures of visual anticipation and visual RT were taken at 3.5 months and 4 years of age. In addition, manual RT and verbal and performance IQ were measured at 4 years of age. Infant visual RT correlated reliably with childhoo...

Although there is substantial evidence that 30-month-old children can reason about other people's desires, little is known about the developmental antecedents of this ability. A food-request procedure was devised to explore this understanding in 14- and 18-month-olds. Children observed an experimenter expressing disgust as she tasted 1 type of food...

We examined whether children's (Grades 2-6) causality beliefs about school performance show similar developmental profiles across 6 distinct sociocultural settings (Los Angeles, n = 657; Tokyo, n = 817; East Berlin, n = 313; West Berlin, n = 517; Moscow, n = 551; Prague, n = 768) with the Means-Ends subscale of the tripartite Control, Agency, and M...

This study examined the effect of attention on 3- to 6-month-olds responses to briefly exposed visual stimuli. In Study I, stimuli presented at 2.5 or 5.0 s resulted in a familiarity preference in a subsequent paired-comparison procedure. A novelty preference was found with 10.0- or 20.0-s exposure durations. In Study 2, a Sesame Street movie elici...

Fourth and 5th graders (N = 119) were individually interviewed regarding their reactions to completing group-administered, positive and negative peer nomination techniques. Results were consistent with previous findings of no obvious harm; but, additional, unique information regarding children's discussions was identified. For example, 7 children r...

This study compared teaching and learning measures of 16 mother-child and sibling dyads playing a picture categorization game. Target children (mean age = 3 years 11 months) participated in 2 separate sessions, 1 with their mother and 1 with their older sibling (mean age = 6 years 11 months). Although siblings' teaching styles directed target child...
