Declarative and Procedural Memory as Individual Differences in Second Language Aptitude
Domain-general approaches to second language acquisition (SLA) have considered how individual differences in cognitive abilities contribute to foreign language aptitude. Here, we specifically consider the role of two, long-term, cognitive memory systems, i.e., declarative and procedural memory, as individual differences in SLA. In doing so, we define and review evidence for the long-term declarative and procedural memory systems, consider theories that address a role for declarative and procedural memory in L2 acquisition, discuss evidence in support of the claims that these theories make, and conclude with discussion of important directions and questions for future research on the role of declarative and procedural memory as individual differences in assessing L2 aptitude.
