PSYC 3330 - 3 (sensory) Flashcards
Sensory memory
ultra-brief retention, iconic, echoic
Short-term memory
brief retention, memory is in serial order, capacity duration and retrieval
Eye movement
30ms, no visual information gathered
Fixation
300ms, visual information gathered
Trans-saccadic memory
allows information to be integrated across eye movements
Iconic memory
sensory register for visual information
Role of sensory registers
-sensory intergation
-experiential continuity
Iconic memory register accounts for visual information that is:
-relatively stable
-accommodate eye movements
Sperling’s studies showed that:
-Lots of info in iconic memory
-info held for short amount of time
Echoic memory
sensory register for auditory information
Echoic memory takes into account that auditory information is:
-constantly changing
-info spread out over time
Darwin, Turvey, & Crowder (1972) showed that:
-large amount of info held in echoic memory
-info held for longer amount of time
Attention is needed for:
-transfer info from sensory to short-term memory
-conscious awareness of visual info
-maintaining info in short-term memory
