The self‐memory system: Exploring developmental links between self and memory across early to late childhood

This study tests whether developments in self‐knowledge and autobiographical memory across early to late childhood are related. Self‐descriptions and autobiographical memory reports were collected from 379 three‐ to eleven‐year‐old predominantly white Scottish children, Mage = 90.3 months, SD = 31.1, 54% female. Episodic memory was measured in an enactment task involving recall and source monitoring of performed and witnessed actions. The volume and complexity of self‐knowledge and autobiographical memory reports increased with age, as did source monitoring ability and recall bias for own actions. Regression analyses and structural equation modeling confirmed a close association between these developments. These results inform our theoretical understanding of the development of the self‐memory system in childhood, which may contribute to the gradual offset of childhood amnesia.
