Freud’s phallic stage occurs in early childhood (roughly 3–6 years) [Parens, 1990, PMID 2229884]. Piaget’s pre-operational stage spans about 2–7 years and thus covers the same developmental window [Asokan, 2014, PMID 25231036]. Therefore, the phallic stage aligns best with Piaget’s pre-operational stage.
