Unformatted text preview: 1 Memory: part 1 Memory What is memory?--The storage and retention of information and events about the world.--A record of the past which is constantly used to affect the present. Memory-Outline I. Information Processing Model of Memory A. Memory Stores B. Control Processes C. Kinds of Memories/Knowledge II. Sensory Memory III. STM and Encoding into LTM IV. LTM--Representation and Organization V. LTM--Retrieval VI. Neuropsychology of Memory Information Processing Model of Memory 3 Memory stores with different functions, capacities, and durations: Sensory Memory => STM <=> LTM Information Processing Model of Memory Sensory Memory : A trace of the sensory input is retained for a brief period. High capacity and short duration. Short-Term Memory (STM) (also called “Working Memory”) : Attentive/conscious processing occurs here. Information can enter STM from both sensory memory and LTM. Small capacity and short duration. Long-Term Memory (LTM): The stored representation of knowledge gained from previous experience. Unlimited capacity and indefinite duration. Information Processing Model of Memory "Control Processes ": manipulate information within or between stores Encoding--movement of information from STM to LTM. Storage--maintaining information over time in LTM. Retrieval--movement of information from LTM to STM (remembering). 2 W. W. Norton Information Processing Model of Memory Kinds of Memory/Knowledge A. Implicit/Procedural Knowledge--a learned skill or habitual response (e.g., bike riding, conditioning). Is accessible through performance. B. Explicit/Declarative Knowledge--can be made explicit or "declared" in words (or with a picture). Semantic--general knowledge of world (e.g., word meanings such as “bird”). Episodic--knowledge of specific past experience/events (know place and time). Memory-Outline I. Information Processing Model of Memory II. Sensory Memory III. STM and Encoding into LTM IV. LTM--Representation and Organization V. LTM--Retrieval VI. Neuropsychology of Memory Sensory Memory Visual sensory memory = "iconic memory " How much can be seen in a single glance? e.g., brief presentation of an array of letters. Sperling-- partial report procedure : Subjs asked to report only 1 row of the array, chosen after the physical stimulus disappeared. The cue tells subjects which letters in the sensory trace to transfer into STM for report.
