Multi Store model Flashcards
What is encoding
The form in which information is stored
What is storage
Keeping information within the system
SM is?
Sensory memory
STM is?
Short term memory
LTM is?
Long term memory
How is information goes to SM?
By environmental stimuli
How information goes into STM?
Attention
How information goes into LTM?
Elaborative rehearsal
What do you do in order to keep information within the STM?
Maintenance rehearsal
What types of encoding is in SR?
Iconic, echoic, olfactory, gustatory, haptic
Capacity of SR?
Very large
Duration of SR?
Less than half a second
STM duration?
18-30 secs
Capacity of STM
7+/-2
Encoding of STM
Acoustic and visual
Who studied the duration of STM and how
Peterson and Peterson, using consonant trigrams
After 3 sec recall was 80%
After 18 sec it was 10%
After 30 sec information is starting to decay
Who studied capacity of STM and how
Jacobs (1887) by using digit span test
Gave sequence of digits and increased it by one every time
Who studied encoding of STM and how?
Baddley (1966) 4 list of words
Who studied encoding in LTM and how
Baddley (1966) asked to recall C and D lists after 20 minutes (C was worse because of similar meanings)
Duration LTM was studied by and how
Bahrick (1975) yearbook study, after 15 years it was 90% accurate, after 48 years it was 70%
What problem did Clive Wearing had?
Brain infection, which supports that memory decays after 30 secs
HM problem and what he could do?
Provides evidence for STM that it has different sections for visual and auditory information.
