Covers normal physical, psychosocial, and cognitive topics from infancy through adolescence.

This video will take the viewer through two stages: (1) middle childhood, when children build on what they learned in early childhood, and (2) early adolescence, when children begin to undergo the changes associated with puberty. Human development principles and physical, emotional, social and intellectual development are covered.

The aim of this program is to examine Piaget’s theory and to critically evaluate it in light of modern research. The program concludes that children are more cognitively capable at an earlier age than Piaget suggested, but it is the ages rather than the stages that are disputed. (57 minutes)
