From birth, infants detect associations between the locations of static visual objects and sounds they emit, but there is limited evidence regarding their sensitivity to the dynamic equivalent when a sound-emitting object moves. In 4 experiments involving thirty-six 2-month-olds, forty-eight 5-month-olds, and forty-eight 8-month-olds, we…

Examined the behavior of 8.5-month-old crawling infants and 14-month-old walking toddlers in ascending and descending sloping walkways. Both groups overestimated their ability to ascend slopes. Toddlers hesitated most before descending 10 and 20 degree slopes, whereas infants hesitated most before descending 30 and 40 degree slopes. (MDM)

Describes two experiments that assessed young children's understanding of the characteristic uncertainty in the physical nature of random phenomena as well as the unpredictability of outcomes. (HOD)

Examined the ability of 1-year olds to remember the location of nonvisible targets. Found that infants were able to associate a nonvisible target with a direct landmark and to code its distance and direction with respect to themselves or the larger framework. Difficulty of coding with indirect landmarks was associated with cognitive complexity and…

Two experiments investigated the possibility that three year olds would do better on tasks in which belief cues were stronger than on standard false belief tasks, in which the children could reason backward to the belief from its effects. Findings provided strong support for the view that three year olds do not fully understand the…

First- and fifth-grade children were presented a hypothetical case in which a child, who circumstantial evidence suggests might have committed a "crime," is punished by a parent. Subjects were asked to indicate whether or not they believed the punishment to be fair and the child guilty. (Author/RH)

A core task in language acquisition is mapping words onto objects, actions, and events. Two studies investigated how children learn to map novel labels onto novel objects. Study 1 investigated whether 10-month-olds use both perceptual and social cues to learn a word. Study 2, a control study, tested whether infants paired the label with a…

Results showed that infants can differentiate dynamic, multimodal expressions as early as five months of age; can distinguish dynamically distinct expressions before similarly animated expressions; and seem to rely more on the voice than the face in making these discriminations. (RH)

Deals with (1) developmental changes in children's concepts of difficulty and ability and (2) individual differences within different developmental levels. Three levels of understanding of ability and difficulty are proposed, and cross-sectional and longitudinal evidence of progressive development through the stages is presented. (Author/RH)

Harter's Perceived Competence Scale for Children was administered to 714 Taiwanese fifth graders; results were compared with those from American samples. Cultural differences were found. Results among Chinese replicate the measures' factorial validity and, across the two groups, indicate a high correlation between perceived cognitive competence…
