Although human infants demonstrate early competence to retain visual information, memory capacities during infancy remain largely undocumented. In three experiments, we used a Visual Paired Comparison (VPC) task to examine abilities to encode identity (Experiment 1) and spatial properties (Experiments 2a and 2b) of unfamiliar complex visual…

How do capuchin monkeys learn to use stones to crack open nuts? Perception-action theory posits that individuals explore producing varying spatial and force relations among objects and surfaces, thereby learning about affordances of such relations and how to produce them. Such learning supports the discovery of tool use. We present longitudinal…

This experiment asked whether infants at 5 months perceived an invariant over four types of rigid motion (perspective transformations), and thereby differentiated rigid motion from deformation. Four perspective transformations of a sponge rubber object (rotation around the vertical axis, rotation around the horizontal axis, rotation in the frontal…

Behavioral studies of early visual development are interpreted within a framework provided by data from the neurosciences. Conclusions concerning the visual responses elicited during the first month of life and the more sophisticated reactions appearing during the second and third months of infancy are presented.

Outlines a study which examines adult interpretations of infant nonverbal behavior. Contends that negative nonverbal emotions are more likely to be attributed to male infants, and positive nonverbal emotions are more often attributed to female infants. (MH)

This review of literature on children's learning focuses on the following seven subject areas: (1) Infant learning, particularly studies of conditioning and individual differences in infants, (2) New perspectives on Piaget, reviewing studies where conservation and transitive inferences have been taught to young children, (3) Language and…

Study investigated whether the observed individual differences in visual pursuit endure beyond the neonatal period. (Authors/MB)

The reaching behavior of 12 infants in the presence of solid objects and pictures of objects placed within and beyond possible contact distance was videotaped in three sessions at 15, 19, and 24 weeks of age. (Author/MS)
