Leslie B Cohen
Les Cohen was Professor of Psychology in the Developmental area and the Cognitive Systems area at UT until his retirement in 2010. He was the founding editor of the journal Infancy, published by the International Society on Infant Studies.
His primary research interests are in perception, memory, and cognition of infants. In general, he and his students in the Infant Cognition Laboratory examined how infants process and integrate visual and auditory information from their environment. Most research projects involve some variation of a visual habituation paradigm, which Dr. Cohen developed for use in infant research. In this paradigm, infants' looking times are recorded while they are repeatedly shown either a single stimulus or multiple stimuli and are then tested with familiar versus novel stimuli. Most of the stimuli are actual events generated through sophisticated computer animation techniques or videotaped and then presented to the infants. The laboratory also developed Habit 2000, a multipurpose software program for testing infant perception and cognition. Habit 2000 is currently being used by more than 30 infant laboratories around the world.
