Document Summary
Memory does not have one single capacity, structure, or process. Digit-span task: a list of digits will be read to you at a rate of 1 digit/sec. Listen to the digits, then write them out in order from memory. The # of items (letters, digits, words) you can remember in order. It is a measure of short-term (working) memory. The sequence of length that yields perfect recall on 50% of the trials. Can be a non-integer # (like 6. 5) Memory span is the # of items within a fixed window of time. Terms from early computer info processing influenced psych lingo. Encoding: transformation of sensory input that allows it to be entered into memory. Storage: the operation of holding or retaining info. Retrieval: the process by which stored info is extracted from memory. S. f. had a normal memory span (=8), but after 230+ hours of practice, s. f. could reliably recall sequences of length 80, in order!
