Document Summary
Psych 207 - lecture 5 - memory structures. Terms retrieval: calling to mind of previously stored info. Storage: forgetting: occurs when we cannot retrieve information. A visual sensory memory, an auditory, an olfactory (smell), a gustatory (taste), and tactile (touch) two types: icon and echo icon: sensory memory for visual stimuli, brief visual memory. Sperling: partial-report technique = visual store could hold about nine items, but only held these info. briefly. Masking (averbach and coriell) = icon can be erased by other stimuli presented immediately after icon. Short-term memory (only lasts for minute or two) Serial position effect: phenomenon that items at beginning/end of a list of items are more easily recalled than items from middle of the list. Primacy effect: improvement in retention of info. learned at the beginning of a task, effect disappears if not rehearsed recency effect: improvement of retention of info. learned at the end of a task.
