The document outlines Erik Erikson's eight stages of psychosocial development, including the main conflict or task at each stage and the corresponding age range. The stages are: trust vs mistrust (infancy), autonomy vs shame and doubt (early childhood), initiative vs guilt (preschool), industry vs inferiority (school age), identity vs role confusion (adolescence), intimacy vs isolation (young adulthood), generativity vs self-absorption (adulthood), and integrity vs despair (later adulthood).
The document discusses Gestalt psychology and the contributions of Kurt Koffka and Wolfgang Kohler. It outlines Kohler's experiments with apes that demonstrated insight learning, challenging the idea that animals only learn through conditioning. It also describes the key Gestalt laws of organization, including Pragnanz, Similarity, Proximity, and Closure. The document references several online sources about Gestalt theory and Kohler's experiments.
