Document Summary

Working memory- controlled use of info in stm; active processing or manipulating of info in stm. Important job is to regulate the flow of info in the current stream of thought supervisory attentional system. The phonological loop, visuospatial sketchpad, and episodic buffer are specialized subsystems under the control of a generalized executive controller, which runs the operation. Are all limited capacity, temporary storage systems. Components can be disrupted by doing similar tasks (ex. visuospatial sketchpad by visual-spatial, but not verbal tasks) Interference is 2 tasks use resources from the same part of working memory: cross-system deficits are typically observed only when executive controller processes are affected, such as when the tasks involve relatively large memory loads. Load maintenance requires: access to phonological store, minor attentional resources to schedule rehearsal. Grammatical reasoning requires: attentional resources for sentence understanding/reasoning, limited access to phonological store note: sentences presented visually. As load increases, attentional demands increase thus, less capacity available for sentence processing.
