What are Freud's stages of childhood sexual development called?

The correct terminology for Freud's framework of childhood development is indeed referred to as the psychosexual stages. This concept is central to Sigmund Freud's psychoanalytic theory and posits that children pass through a series of stages in which they derive pleasure from specific erogenous zones. Freud identified five distinct stages: oral, anal, phallic, latency, and genital, each characterized by different challenges and experiences influencing personality and behavior.

The other choices represent different developmental theories entirely. "Stages of Psychosocial Development" refers to Erik Erikson's theory, which emphasizes social influences and conflicts. "Cognitive Development Stages" relates to Jean Piaget's theory focused on the evolution of thinking and understanding in children. Lastly, "Behavioral Stages" does not correspond to a recognized theory as clearly as the other two, and primarily denotes approaches that examine observable behavior rather than underlying psychological processes. Thus, the alignment of Freud's work specifically with psychosexual stages is what makes this answer accurate.
