PSY 357 Exam 2 Elliott Cal Poly Study Guide
Questions with Complete Solutions
three processes of memory
acquisition, storage, retrieval
acquisition
gaining information and placing it into memory
storage
holding information in memory until needed
retrieval
finding information and bringing it into active use
the modal model (three levels of memory)
sensory memory, short-term memory, long-term memory
newer development: short-term memory + sensory memory = ?
working memory
sensory memory
quick and short-lived
short-term memory
current information
long-term memory
, permanent and limitless storage
sensory memory: iconic (experiment)
quickly presented display of random chart of letters
immediate cue: iconic memory can be accessed; cue helps any row
delayed cue: info decays and recall decreases
demonstrates large, short duration, capacity of sensory memory
testing primacy and recency: serial position
compared to middle words, better memory for: first few words (primacy) and last few words
(recency)
primacy effect
time to rehearse and store words in long-term memory
recency effect
words maintained in working memory
manipulating long-term memory (serial position)
slow presentation (9 s/word) equals more time to store all words in LTM; fast equals no time;
improves primacy effect and middle word recall
manipulating working memory (serial position)
filled delay (e.g., math problems for 30 s) interrupts rehearsal in WM; eliminates recency effect
components of working memory
