PSY 322 Study Guide - Midterm Guide: Sensitivity And Specificity, Interference Theory, Echoic Memory
Document Summary
Atkinson & shiffrin | modal model of memory each stage = structural features: sensory memory holds all incoming info for seconds. Retention of effects of sensory stimulation: short-term memory holds 5-7 items for 15-30s, long-term memory holds large amount of info for years/decades. Control processes: active processes that can be controlled by person and may differ from one task to another: rehearsal = repeating stimulus over/over, strategies of attention/memory that help to form long-term memories. Encoding = storing a stimulus into ltm (by rehearsal/control) Revival = remembering info stored in ltm: persistence of vision: retention of perception of light (sparklers disappear in dark, Sensory memory registers lots of info, but retains for only seconds. Recall test: participants presented with stimuli and asked to remember as many as possible after delay. Memory performance measured by % of stimuli remembered. Recognition: pick item previously seen/heard from list of items not seen.
