The time-based resource-sharing model of working memory
Since Baddeley and Hitch's (1974) seminal proposal to distinguish between short-term and working memory, several influential models and theories have been put forward to account for the structure and functioning of a working memory thought of as the core system of cognition devoted to the maintenance and processing of relevant information. As Engle and Oransky (1999) suggested, deas about tempo...
متن کاملMathematical transcription of the 'time-based resource sharing' theory of working memory.
The time-based resource sharing (TBRS) model is a prominent model of working memory that is both predictive and simple. TBRS is a mainstream decay-based model and the most susceptible to competition with interference-based models. A connectionist implementation of TBRS, TBRS*, has recently been developed. However, TBRS* is an enriched version of TBRS, making it difficult to test general charact...
متن کاملTime constraints and resource sharing in adults' working memory spans.
This article presents a new model that accounts for working memory spans in adults, the time-based resource-sharing model. The model assumes that both components (i.e., processing and maintenance) of the main working memory tasks require attention and that memory traces decay as soon as attention is switched away. Because memory retrievals are constrained by a central bottleneck and thus totall...
متن کاملResource-sharing in multiple-component working memory
Working memory research often focuses on measuring the capacity of the system and how it relates to other cognitive abilities. However, research into the structure of working memory is less concerned with an overall capacity measure but rather with the intricacies of underlying components and their contribution to different tasks. A number of models of working memory structure have been propose...
متن کاملThe role of speed in ADHD-related working memory deficits: A time-based resource-sharing and diffusion model account.
Several recent commentaries suggest that, for psychological science to move beyond "homuncular" explanations for cognitive control, it is critically important to examine the role of basic and computationally well-defined processes (e.g. cognitive processing speed). Correlational evidence has previously linked slow speed to working memory (WM) deficits in ADHD, but the directionality of this rel...
