This talk will present the Time-Based Resource-Sharing model of working memory (Barrouillet & Camos, 2015).
In a multi-level cognitive architecture, a central system, conceived as a self-regulated executive loop involving an episodic buffer and a production system, integrates information from peripheral domain-specific buffers and long-term memory. The executive loop is responsible for constructing working memory representations, for maintaining these representations in the face of decay and interference, and for goal-directed processing by triggering executive functions that modify the content of these representations when needed. Apart from a phonological loop able to maintain a limited amount of verbal information through verbal rehearsal, peripheral buffers are conceived of as passive sensory memories with no specific mechanisms of maintenance. Assuming a sequential functioning of the executive loop and the temporal decay of working memory representations, the theory makes a series of predictions about the time-related effect of processing on concurrent maintenance and the postponement of processing by maintenance activities. This talk will review empirical findings in young adults supporting these predictions as well as studies in children, which shed light on factors of working memory development.
