Study of perceptual exploration was undertaken to see to what extent school experience would produce left-right patterns on several kinds of figures which have strong Gestalt properties. (Author)

Competence in action perception seems to be achieved very early in life. Because research has indicated that competent perceivers of action must be able to discriminate breakpoints in behavior, then recognition memory for breakpoints should be superior to that for nonbreakpoints at all ages where competence in action perception exists. Two studies…

Examines the roles of age of rater and age of children rated in grade-related shifts in children's perceptions of aggression and withdrawal. Shows that differences across grade level reported in children's peer rating largely reflect differences in the child raters' view of behavior. (HOD)

Fixation time, smiling, vocalization, and fret/cry were recorded to obtain a complete picture of infants' responses to facial stimuli over the first year of life. Four stimuli were presented to 120 infants. Results of fixation data indicate that (1) there is a marked decrease in fixation toward facial stimuli within the first year, (2) at all ages…

Examines the implications of temporal separation for children's developmental differences in inferences drawn about an individual's characteristics after observing multiple instances of that individual's behavior. Also tests two competing hypotheses about how young children process information separated in time. (HOD)

This study attempts to identify potential school problems in preschool children in order to facilitate the provision of relevant information for systematic screening and early guidance. Data from the first 14 months (to the end of the preschool period) of a longitudinal study extending from 4 1/2 years of age to the end of second grade are…

A research project of environmental learning in children is discussed. Most of the studies conducted during the research involved observation of children aged 3-12, in mapping and free environmental behavior, and in curricular experiments using perceptual surrogates for map-learning and macro-environmental conceptualization in the lower elementary…
