Cognitive Reorganization during Pregnancy and the Postpartum Period: An Evolutionary Perspective

Where the non-human animal research investigating reproduction-induced cognitive reorganization has focused on neural plasticity and adaptive advantage in response to the demands associated with pregnancy and parenting, human studies have primarily concentrated on pregnancy-induced memory decline. The current review updates Henry and Rendell's 2007 meta-analysis, and examines cognitive reorganization as the result of reproductive experience from an adaptationist perspective. Investigations of pregnancy-induced cognitive change in human females may benefit by focusing on areas, such as social cognition, where a cognitive advantage would serve a protective function, and by extending the study duration beyond pregnancy into the postpartum period.
