The study of cognitive development is concerned with changes in the way that information is encoded, transformed, and responded to as a function of age. The scope of this course ranges from the perceptual and motor abilities of young infants, to the memory functioning of elderly people. Several different perspectives leading to an understanding of cognitive development through the life span will be examined, including the Piagetian approach, age-related changes in information processing, and the acquisition of concepts and beliefs within specific knowledge domains. The applied relevance of developmental findings will also be considered.
