Memory 20:08 Information processing model of memory (see book). Sensory input is held for 1-3 seconds in the sensory register. If you attend to something, it goes into Short-term memory (working memory) o Here it may be rehearsed to reach Long-term memory o If it is not rehearsed, it will be forgotten Long-term memory is unlimited in capacity, as far as we know. Lost information: Sensory memory: info lost in 1-3 seconds Working memory: Unrehearsed info lost in 10-15 seconds Long-term: Some info lost over time.  Once info gets into long-term memory, it is pretty  durable. Sensory Register: Initial, brief storage of sensory info Fades quickly (est. 1-3 sec) Separate store for the separate sense.  Ex. Iconic fades a little more quickly than echoic. Sensory Memory: Test by Sperling in 1960 Report as many letters as possible when shown for a brief moment o Tests Iconic memory Typical results o People do alright until 4.5 items to remember.
