Chapter 8: Memory and Information  Processing 04:33 The Information-Processing Approach Information-Processing Approach – Emphasizes the basic mental processes involved in attention, perception, memory, and decision making. o Must determine how the hardware/software of the mind change over the life span. Memory Systems Atkinson and Shiffrin (1968): early/influential conception of the human info- processing system Sensory register – 1 st memory store in info processing in which stimuli are noticed and are briefly available for further processing. o Much that strikes the register quickly disappears, w/out processing. o Like an Echo. Short-Term Memory – The memory store in which limited amounts of info (about 7 items or chunks of information) are temporarily held; called working memory when its active quality is being emphasized. o Working Memory – A mental “scratch pad” that temporarily stores info while actively working on it. It is what is on one’s mind at any moment. Long-Term Memory – Memory store in which info that has been examined and interpreted is stored relatively permanently. Simplified Model: o Encoding – 1 st step in learning and remembering something. The process of getting info into the info-processing system, or learning it, and organizing it in a form suitable for storing. o Consolidation – The processing and organizing of info into a form suitable for long-term storage. Transforms the sensory-perceptual experience into a long-lasting memory trace, through sleep. o Storage – The holding of info in the long-term memory store. o Retrieval – The process of retrieving info from long-term memory when it is needed. Recognition Memory – Identifying an object or event as one that has been experienced before (when a person must select the correct answer from several options). Easiest.

Cued Recall Memory – Recollecting objects, events or experiences in response to a hit or cue. Harder. Recall Memory – Recollecting or actively retrieving objects, events, and experiences when examples or cues are not provided. Hardest. Implicit and Explicit Memory Implicit Memory – Memory that occurs automatically, unintentionally and without consciousness or awareness. o When tested, they do not know memory is being assessed. o Largely infallible – it remains intact o Changes little; young children often do no worse than older children and elderly adults do no worse than younger adults. Explicit Memory – Memory that involves consciously and deliberately recollecting the past. o Tested through traditional recognition and recall tests o Typically involves info that can be described with language. o
