PSY 357 EXAM 2 ELLIOTT CAL POLY QUESTIONS WITH CORRECT ANSWERS

PSY 357 EXAM 2 ELLIOTT CAL POLY QUESTIONS WITH CORRECT ANSWERS .three processes of memory - ANSWERS-acquisition, storage, retrieval .acquisition - ANSWERS-gaining information and placing it into memory .storage - ANSWERS-holding information in memory until needed .retrieval - ANSWERS-finding information and bringing it into active use .the modal model (three levels of memory) - ANSWERS-sensory memory, short-term memory, long-term memory .newer development: short-term memory + sensory memory = ? - ANSWERS-working memory .sensory memory - ANSWERS-quick and short-lived .short-term memory - ANSWERS-current information .long-term memory - ANSWERS-permanent and limitless storage .sensory memory: iconic (experiment) - ANSWERS-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 - ANSWERS-compared to middle words, better memory for: first few words (primacy) and last few words (recency) .primacy effect - ANSWERS-time to rehearse and store words in long-term memory .recency effect - ANSWERS-words maintained in working memory .manipulating long-term memory (serial position) - ANSWERS-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) - ANSWERS-filled delay (e.g., math problems for 30 s) interrupts rehearsal in WM; eliminates recency effect .components of working memory - ANSWERS-central executive, visuospatial buffer, articulatory rehearsal loop (subvocalization and phonological buffer) .central executive - ANSWERS-in charge of lower-level aspects of WM; "helpers," where plans or decisions are made .visuospatial buffer - ANSWERS-visual material .articulatory rehearsal loop - ANSWERS-subvocalization: launches rehearsal loop phonological buffer: passively stores sound representation .working memory capacity - ANSWERS-number of items stored in WM different from person-to-person; positively correlated with reading comprehension, reasoning tests, academic achievement .measuring working memory capacity: digit span task - ANSWERS-listen to a list of numbers; repeat it back; after first mistake previous number is digit span
