Self-derivation through memory integration: a longitudinal examination of performance and relations with academic achievements in elementary classrooms

Abstract

Self-derivation through memory integration is the cognitive process of generating new knowledge by integrating individual facts. Across two studies, we longitudinally examined developmental change, individual stability, and relations with academic performance in a diverse agricultural community. We documented children’s self-derivation in their classrooms and examined the relation with self-derivation and academic performance a year later. In Study 1, we examined self-derivation (n = 94; Mage= 6.67; initially grades K and 1) using the same paradigm at both time points. We found evidence of developmental change from Time 1 to Time 2. However, self-derivation accounted for a small portion of the variance in self-derivation (reflecting individual stability) and academic performance measured one year later. In Study 2, we examined self-derivation across two different paradigms with children beginning in Grades 2 and 3 (n = 82; Mage= 8.60). Even across paradigms, we found evidence for individual stability. Year 1 self-derivation also predicted Year 2 academic performance. We posit that self-derivation through integration is a domain-general construct related to academic performance.
