The document discusses four approaches to child development: behaviorism, constructivism, evolutionary psychology, and socioculturalism. Behaviorism views learning as the formation of associations between stimuli and responses, while constructivism sees development as qualitative stage transitions where children create their own knowledge through active interaction. Evolutionary psychology argues that human minds are designed by evolution to learn certain things easily. Finally, socioculturalism posits that learning occurs best through social interaction and apprenticeship within communities.
