Based on PhD dissertation submitted to the University of California, Los Angeles.

Pancratz, Charity N.; Cohen, Leslie B. – J Exp Child Psychol, 1970
Male infants habituated their fixation time over trials and differentiated between the novel and familiar stimuli when the posthabituation interval was 15 seconds, but neither male nor female infants did so when the interval was 5 minutes. This paper is based upon a thesis submitted by the first author in partial fulfillment of the requirements…

Peer reviewedCohen, Leslie B.; Oakes, Lisa M. – Developmental Psychology, 1993
Describes 4 experiments examining 10-month-old infants' causal event perception. Results from all experiments indicated that infants perceived causality of simple events by associating a specific agent with a causal action. These results provide more support for an information-processing view of causal perception than for a view that explains…

Peer reviewedCasasola, Marianella; Cohen, Leslie B.; Chiarello, Elizabeth – Child Development, 2003
Two experiments examined six-month-olds' ability to form an abstract containment category. Results indicated that, after habituation to object pairs in a containment relation, infants looked reliably longer at an example of an unfamiliar versus familiar containment relation, indicating that they could form a categorical representation of…

Peer reviewedCasasola, Marianella; Cohen, Leslie B. – Developmental Psychology, 2000
Six experiments examined infants' ability to associate nonsense words with two causal actions: pushing and pulling. Eighteen-month-olds, but not 14-month-olds, formed word-action associations. Fourteen-month-olds discriminated a change in label but not a change in action when the other was held constant. When language labels were replaced with…

This experiment examined developmental changes in the ability of infants to learn conceptual categories regarding the human face. A total of 108 infants, aged 18, 24, and 30 weeks, were habituated to (1) the same face in the same orientation, (2) the same face in differing orientations, or (3) different faces in different orientations. All…

Cohen, Leslie B. – 1972
A two-process model of infant visual attention is constructed based on research using the modified Berlyne technique with three- to five-month olds. The length of time an infant fixated a pattern was examined along with what caused him to turn to the pattern at all. The study was based both on a re-examination of previous research and on new…

Peer reviewedCohen, Leslie B. – American Psychologist, 1979
Reviews research and current knowledge regarding infant auditory and visual perception and concludes that from a very early age, infants are able to perceive the world around them and organize their perceptual experience. Outlines areas for future research and application. (GC)
