Document Summary

Information that is retained longer than the stimulus that created it. Model of memory: sensory memory, short-term memory, long-term memory, sensory memory: briefly holds incoming sensory information (we receive through our senses). Memory codes: visual, phonological, sematic, motor. Capacity of short-term memory: the magic number 7+-2, chunking: combining individual items into larger units of meaning. Duration of short-term memory: repetition keeps the memory active for a couple of seconds or minutes. If the information is not repeated again and again in the mind then, it gets deleted from the mind in about 15-20 seconds. Working memory: temporarily stores and processes information: phonological loop: stores mental representation of sounds, visuospatial sketchpad: stores visual and spatial information, long-term memory: our library of more durable stored memories. Memories can endure for a lifetime: debatable, permanence vs alteration. v how do we know .
