chapter 5 terms Flashcards
What are the three parts of the memory system?
Encode, take info, store info place info, retrieve remember info for later use
Modal modal of memory
serial position graph baseline
People tend to remember words at the start and at the end of lists
Serial position 2 speed
When a list is said fast people tend to forget the first few words of the list but remember the last few words. There is no primacy effect but recency stays
Serial position 3 distractor
When people are asked to count at the end of the list be distracted there is no recency effect but there is primacy effect still
Sperling whole report
Showed a list of letters 12 of them people had to recognize if set letter was presented, people correctly answered 4-5 times out of 12
sperling partial report procedure
list of words of was showed just like whole report but this time a cue was presented. People remembered 9 out of 12 words
Partial report with a delay
same as partial report procedure but this time the cue was delayed, people remembered about 3-4 words after the delay.
Duration and capacity of STM
lasts about 15-30 seconds or as long as repetition continues with no interruption. Can store about 5-9 items
condrad tests
test Auditory had participants writre letters one after another, noticed people made mistakes when the letters sounded similar.
posner and keele
presented letters one after another compared the size and shape of them, people tended to react slower when the size and shape were meaning people visually take in the info
shulman
test deals with meaning, flashed a group of words to participants later asked them if the word was there, participants confused words based of synonyms
3 problems with the system of STM
1 word length effect, 2 phonological similarity 3 articulation suppression
control processes
active processes we can control rehearsal memorization techniques
sensory memory
first stage of model modal hold echoic audio or visual message for 1/2 a second, memory decays quickly
iconic memory
holds visual info part of sensory memory
echoic
holds audio or verbal messages
Brown and peterson task
had people recall three letter words then count by 3 backwards to prevent repetition
Chunking
combining small individual units into larger units more efficient way of remembering lists
Who is sf and what he do
Sf is a patient who was trained in chunking to remember well over 80 numbers at a time, trained countless of hours
Chase and simon
players had to memorize chess board had two groups beginners of and master level players. chess masters were able to place 16 pieces back to place if the board had meaning but if no meaning were only able to place 4-5 pieces back like beginners
word length effect
the longer a word is the more difficult it will be to remember
phonological similarity
if words sound similar then it will be more difficult to remember the words and distinguish them
articulatory suppression
repeating a word will make it more difficult to remember and store on phonological store
phonological loop
part of working memory under sensory memory takes in auditory or verbal codes stores them
What two parts are under phonological loop
1 phonological store part of the phonological loop holds in auditory or verbal messages for 2-4 seconds.
2 subvocal rehearsal part of the phonological store you remember the verbal info by repeating it to yourself.
what region of the brain is involved with STM/WM
the frontal lobe and parietal lobe.1 Parietal lobe has to do with somatosensory input physical touch, attention 2 Frontal lobe higher level of thinking deep thoughts language output decision making motor control
Visualspatial sketch spad
Holds in visual or spatial memory is part of sensory memoery
central executive
part of working memory that coordinates the activity of both the phonological loop and visuospatial sketchpad
