Young infants perceive an object's trajectory as continuous across occlusion provided the temporal or spatial gap in perception is small. In 3 experiments involving 72 participants the authors investigated the effects of different forms of auditory information on 4-month-olds' perception of trajectory continuity. Provision of dynamic auditory…

Three experiments assessed the ability of 2 to 5-year-old children to infer, under very simple task conditions, what another person sees when viewing something from a position other than the children's own. (ST)

In a study of spatial perspectives, third- and fifth-grade students were asked to coordinate perspectives on single-object and multiple-object arrays. (ST)

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)

Results of two studies indicated that three- and four-year-old children understood that, although perception is necessary for knowledge, it is irrelevant for imagination and that three year olds often claimed that imagination reflected reality. (MDM)

This study sought to assess the ontogenetic course of three classes of size-value phenomena. Size-value phenomena refers to the observation that valued and neutral objects physically equal in size are judged as unequal. Results are discussed in terms of perceptual development. (ST)

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…

This study examined whether 16-month-old walking infants take the material composition of a handrail into account when assessing its effectiveness as a tool to augment balance. Infants were encouraged to cross from one platform to another via bridges of various widths (10, 20, 40cm) with either a wobbly (foam or latex) or a wooden handrail…

Examined 2-month-old infants' perception of sparse random-dot displays depicting an illusory shape against a background in three experiments in which background texture, luminance cues, and relative motion information were added or deleted. Found that infants preferred novel stimuli in each condition, revealing an early capacity to perceive shape…

Subjects of this study were 144 White, middle-class children in kindergarten, first, second, and fourth grades. Children were interviewed individually about their explanations for both academic and social outcomes and their evaluations of their own outcomes. Self-evaluations became less positive in both domains and less similar across domains with…
