Object exploration is considered a driver of motor, cognitive, and social development. However, little is known about how early childhood education and care settings facilitate object exploration. This study examined if children's exploration of objects during free play was facilitated by the use of particular spatial components (floor, tables,…

This paper is in memory of Esther Thelen, who passed away while President of the Society for Research in Child Development. A survey of Esther Thelen's career reveals a trajectory from early work on simple movements like stepping, to the study of goal-directed reaching, to work on the embodiment of cognition, and, ultimately, to a grand theory of…

Two studies found infants' scores on the Range of State Cluster of the Neonatal Behavioral Assessment Scale with Kansas Supplements to correlate significantly with visual discrimination performance at three months of age. The correlation with behavioral state organization contradicted the prediction that orientation scores would predict visual…

Young children usually prefer to classify objects on the basis of shape rather than color. The present study explored this phenomenon with a stimulus matching test and a component selection test. (ST)

Visual behavior of infants was assessed with multiple discrimination tasks week to week from four to seven months of age. Task to task reliability was low, but attentional averages from week to week were reliable. Generally, infants with shorter fixations showed more novelty preferences, and infants' shift rate improved with age. (SKC)

A path model of genetic and shared family environmental transmission was fitted to general cognitive ability data from 1-, 2-, 3-, and 4-year-old adopted and nonadopted children and their parents to assess the etiology of longitudinal stability from infancy to early childhood. (HOD)

Examines the conceptual basis of preschoolers' judgments regarding cross-gender behavior, taking into consideration the type of sex-role regularity and whether it is male or female sex-role stereotype. (HOD)

Tested infants in their second year with a box task to determine whether they would show a hand preference in solutions involving complete differentiation of roles for the two hands. (HOD)

Describes two measures of gender salience, one assessing the use of the gender dimension in classifying new information and the other assessing its use in making affiliation choices. The developmental course of gender salience from age three to age seven and the relation between salience and sex-role development were examined. (HOD)

Observed a group of 46 children classified at 20 months as either behaviorally inhibited or uninhibited, and 18 children who were classified aa falling at neither extreme at 5.5 years of age, in contexts designed to evaluate behavior in social situations and heart rate, heart variability, and pupillary dilation to cognitive tasks. (HOD)

Using a longitudinal design, investigates the interactive behaviors of mothers of normal infants and mothers of infants who are known to differ on a host of cognitive, behavioral, and biological parameters. Examines the developmental course of emotional expressivity in these infants. (HOD)

Compared family characteristics and developmental outcomes of African-American children from three rural contexts in South Africa: the homeland, the resettlement, and white-owned farms. Child outcomes were highly intercorrelated in all three contexts, but correlations among family variables, and between family and child variables, showed different…
