Document Summary
What are the three components of working memory: auditory rehearsal, episodic, visual-spatial information. The phonological look (auditory rehearsal) stores a number of limited sounds and acoustic codes; information in this store typically decays within 2 seconds. The visual spatial sketchpad stores visual and spatial information (but with a limited capacity and for an abbreviated period of time). The central executive integrates information from the phonological look and visuo-spatial sketchpad, and retrieves information from long-term memory. It plays a major role in directing attention, planning activities, and controlling behavior. Long term memory is a relatively permanent storage system that has no practical limits. Be familiar with the structure of long-term memory, including the distinction between implicit and explicit memory. Explicit(declarative) memory involves memory for facts and experiences that one can consciously recall. Implicit (nondeclarative) is our memory for skills or responses that operate outside of conscious awareness. Semantic memory involves our general knowledge associated with facts or objects.
