Which theory emphasizes stages of development?

Many psychological theories attempt to explain human development, with some emphasizing a progression through distinct stages, each characterized by unique abilities or challenges.

• The correct answer, Piaget, refers to Jean Piaget's groundbreaking theory of cognitive development. Piaget proposed that children progress through four universal stages: sensorimotor, preoperational, concrete operational, and formal operational. Each stage represents a qualitative shift in how individuals think and understand the world.
• Skinner is associated with operant conditioning, focusing on how consequences shape behavior, not developmental stages.
• Freud developed a theory of psychosexual stages, but in the context of general developmental stages, especially cognitive, Piaget is the most prominent.
• Pavlov is known for classical conditioning, which explains learning through association, not through a series of developmental stages.
