Document Summary
Icon - visual sensory register: echo - auditory sensory register. Auditory sensory memory: we can hold in sm something we hear 6 times longer than what we see. Sensory memory: they are limited in capacity and duration, ~0. 5 seconds for visual, ~3 seconds for auditory. How do we assign meaning to what we perceive: assignment of meaning happens in perception of memory, where we use a pattern from our long-term memory to recognise and assign that meaning. Steps of perception: detection of a stimulus through senses storage of some representation of the stimuli in sensory memory pattern recognition - using knowledge in long-term memory further assignment of meaning to stimuli. Long term memory: temporary storage of information (sm, available patterns retrieved for recognition (ltm, assignment of meaning through awareness (wm) Assignment of meaning: affected by - nature and context of stimulus, and background knowledge, when elements match (pattern recognition) what is in long term memory, recognition occurs.
