Exam Two Questions Flashcards
(40 cards)
what is the purpose of sensory memory?
too keep a record of what each sense has just experienced for a brief period of time
describe George Sperling’s WHOLE report technique
12 letters flash on a screen and the participant must try to recall as many letters as they can
describe George Sperling’s partial report technique
12 letters flash on a screen, a tone is played while or right after they are flashed indicating which line needs to be recalled
what is echoic memory?
persistence of auditory impressions and brief availability for further processing
what is an echo?
representation of an auditory stimulus that is no longer present
is working memory dynamic or static?
dynamic, we work with the information and process it in our memory
what are the four functional components of working memory?
- phonological loop
- visuospatial sketch pad
- central executive
- episodic buffer
what is the evolutionary reason we would have a better echoic memory than iconic memory
we can generally look at threats multiple times, but you usually only have the opportunity to hear something once
what is the rule for how much we can hold in working memory?
7 +/- 2
so 5 is the lower end and 9 is the higher end
what is proactive inhibition (interference)
what you heard from a prior trial may still be rattling around and causing your performance to decrease on future trials
what is the best way to chunk?
by making the chunks into something meaningful (FBI vs. IBF)
can you stretch working memory past the normal limits?
yes, through practice
this is how people memorize hundreds of digits of pi
why can native English speakers remember higher amounts of numbers/letters?
english has very few syllables so you can rehearse them more
in a list, what are we best at recalling:
the first, middle, or last items
first and last are best
(primacy and recency effects)
when searching for an item in a list in our working memories, why does the position of where that item is not matter for reaction time?
we search our working memories serially, meaning that we will still search the whole list item by item even after we’ve seen the item were looking for
what is the most widely accepted theory of working memory?
(describe it)
the multicomponent model (Baddeley)
contains the phonological loop, visuospatial sketchpad, episodic buffer, and central executive
if you are having trouble learning new material because previously learned material is getting in the way, what are you experiencing?
proactive interference
teasdale and colleagues (1995) demonstrated that the ability to generate a list of numbers that appears random is hindered by
a. concurrently using phonological loop
b. poor math ability
c. engaging in verbal expression (la la la)
d. engaging in daydreaming
d. engaging in daydreaming
describe declarative memory and give examples
type of memory that is easy to put into words
episodic and semantic
describe non-declarative memory and give examples
type of memory that is not easy to put into words
procedural
what is the permastore theory
everything you have learned well stays in your memory, you might not remember it outright but you can if cued
the idea of even if you haven’t spoken a language in 10 years you still remember it
what is the decay theory of forgetting?
“use it or lose it”
memory is a shiv and if you are not actively using information it gets lost
what is the interference theory of forgetting?
information you have learned stays in there even if you cannot remember it
cues and context might bring those memories back
what is deep processing
you are extracting some kind of meaning from a stimulus which helps you remember it better
