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…

In 3 studies (N = 188) we tested the hypothesis that children use a perceptual access approach to reason about mental states before they understand beliefs. The perceptual access hypothesis predicts a U-shaped developmental pattern of performance in true belief tasks, in which 3-year-olds who reason about reality should succeed, 4- to 5-year-olds…

The most common behavioral technique used to study infant perception, cognition, language, and social development is some variant of looking time. Since its inception as a reliable method in the late 1950s, a tremendous increase in knowledge about infant competencies has been gained by inferences made from measures of looking time. Here we examine…

This study examined changes in rhythmic arm shaking and laterality biases in infants observed longitudinally at three points: just prior to, at, and just following reduplicated babble onset. Infants (ranging in age from 4 to 9 months at babble onset) were videotaped at home as they played with two visually identical audible and silent rattles…

Discusses C. Milbrath's thesis that artistically talented and less talented children follow different developmental paths because they rely on different ways of responding to the world. Relates this thesis to studies of the childhood work of Paul Klee, Henri Toulouse Lautrec, and Pablo Picasso. (SLD)

Age and condition (either constancy-relevant or variability-relevant) interact, with the youngest group in the constancy-relevant condition performing most poorly on concept identification tasks. (MH)

Despite external changes such as those of magnitudes, the functional properties of the visual system also improve with increased age. According to Jean Piaget's centration/decentration theory, the process of perceptual development might continue until adulthood and even after. However, perceptual development should not be understood in all of its…

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…

Since it is unavoidable that children will experience the death of people and animals through media, literature, and real-life situations, they will need adult help when trying to understand what death is and how it affects them. Researchers generally agree that a child's perception of death is developmental, closely associated to either age or…

Sex and, to a partial degree, age had significant effects on sex role differentiation in preschool children, but income level had little effect. (Author/RL)

Shows that the mother's being employed and the social status of her job were unrelated to preschool children's sex role differentiation. Reports significant main effects for child's sex and for the relation between sex of child and sex of siblings. (Author/RL)

Findings of this Israeli study suggest that perception is affected by lables, learning, and selective attention; that these effects are determined developmentally; and that as age increases, the effects of verbal cues diminish, while the effects of perceptual cues increase. (Author/DLS)
