Infants are born highly sensitive to the natural patterns found in languages. They use their perceptual sensitivity to acquire detailed information about the structure of languages in their environment. To date, most studies of infant perception and early language acquisition have investigated spoken/auditory languages and hearing infants (e.g.…

This paper reviews progress over the past 20 years in four areas of research on infant perception and cognition. Work on perception of dynamic events has identified perceptual constraints on perception of object unity and object trajectory continuity that have led to a perceptual account of early development that supplements Nativist accounts.…

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…

Data gathered on 92 girls (6-10 years of age) tested on Piagetian conservation tasks supports a theory of perceptual activity leading to decentration and indicates a change in viewing strategy associated with change in conservation status. (WY)

This study examined age differences in children's visual fixation and search strategies of two dimensional visual stimuli. The hypotheses tested were: (1) that no age differences exist in general search strategies regardless of stimuli position, (2) that age differences could be expected with respect to the number and duration of visual fixations,…

UNDER THE DIRECTION OF PROFESSOR BRUNER, THE CENTER FOR COGNITIVE STUDIES AT HARVARD UNIVERSITY HAS CARRIED OUT A SERIES OF STUDIES ON THE DEVELOPMENT OF COGNITION. THERE HAVE BEEN OVER 30 EXPERIMENTS ON THE GROWTH OF PERCEPTION, PROBLEM-SOLVING, AND REASONING BETWEEN THE AGES OF 3 AND 10, IN PURSUIT OF A THEORY TO ACCOUNT FOR THE CHANGES IN…
