Paper 1 - Memory Flashcards
What does duration mean?
How long info is stored for
What does capacity mean?
Amount of info that can be stored
What does encoding mean?
How information is changed to be stored (how it’s stored)
What does linear mean?
Info flows along a line
What is a passive processor?
Stores do not work together to process information (e.g. multi-store model)
What does unitary mean?
Single store that processes all info
What is an active process?
Stores work together to process info (working memory model)
What is dual-tasking?
Doing multiple things at one time (multi-tasking)

Explain the A03 for Sperling (sensory)
Participants (ppts) were shown a visual array of 12 letters flashing on the screen for 50 milliseconds . They then reviewed them. On average ppts recalled 4/12 as they faded to quickly
Explain the A03 for Peterson & Peterson (STM)
Ppts were given consonant syllables and 3 digits to learn. Then had to recall them at either 3, 6, 9, 12, 15 or 18 seconds but in between learning & recall had to count backwards from their 3 digit number. 3 secs (90% recall), 18 secs (2% recall)
Explain the A03 for Baddely (LTM)
Ppts given 2 lists to learn, 1 was semantically similar words, 2 was acoustically similar. Ppts had to recall information immediately and 20 minutes later.
Immediate = errors on acoustic (stm codes acoustically)
20 mins later = errors on semantic list (LTM codes semantically)
Strengths of the multi-store model
Primacy and recency proves to separate (primacy - words heard first were in LTM, recency - words heard last were in STM)
Different coding is used by STM (acoustic) and LTM (semantic) - suggests two separate stores
HM (case study) suffered from epilepsy, surgeon removed hippocampus. When woke up personality and IQ was intact but appears he couldn’t make new LTMs (suggests the two separate stores and the STM is a gateway to the LTM, linear)
Weaknesses of the multi-store model
KF (case study) motorbike accident, STM was severely damaged but could make new LTMs. Struggled verbally but not visually (suggests model is not lie and and suggests STM is not unitary)
Flashbulb memories are strong vivid memories that goes straight into LTM without elaborate rehearsal (against idea that memory is linear)
What was the research evidence of the working memory model by Baddeley and Hitch
Aim - investigate dual tasking in STM
Procedure - Ppts given 2 tasks to do at same time
Results - only dual task if using different sub-stores

Strengths of the working memory model
KF (motorbike accident) STM damaged, struggled verbally but not visually and could make new LTM
Suggests STM isn’t unitary and damage was restricted to the articulating loop
Weaknesses about the working memory model
Little known about central executive yet is the controller
EVR had tumour removed, when woke reasoning was fine but couldn’t make decisions. Suggests central executive is more complex (possibly 2 sub-stores)
Suggest need visuals for spatial awareness but blind people have intact spatial awareness with no vision
Suggests the visuo-spatial sketchpad is more complex (possibly 2 sub-stores)
What is a real life application of the working memory model
Dyslexia
What are the 3 times of long term memory?
Episodic, semantic, procedural
What is episodic long term memory?
Events or episodes that we have experienced (meaningful) e.g. first day of school, first kiss
Declarative, able to put into words ‘know that’
What is semantic long term memory?
Facts, general knowledge shared by all. E.g. the grass is green, first day of school
Some examples (school) are both episodic and semantic as closely linked
Declarative, able to put into works ‘know that’
What is procedural long term memory?
Motor or action/skill based memory
E.g. riding a bike
Non-declarative, not able to put into words ‘know how’
What is the location of the different scanning techniques in the 3 types of LTM?
Episodic - hippocampus & temporal lobe
Semantic - temporal lobe
Procedural - frontal lobe & motor cortex
Strengths of the types of long term memory
Corkin -> HM ‘mirror drawing’ task
Corkin worked everyday with HM on mirror drawing, drawing a star in between a star through a mirror.
After a month HM could do this perfectly BUT had no recollection he had been learning it for months nor did he know who Corkin was (due to not being about to make new long term memories).
You can make procedural memories WITHOUT episodic & semantic memories. Procedural is separate!
Weaknesses of the types of long term memory?
It has been suggested that episodic memories are the gateway to semantic memories; we don’t know if semantic memories form on their own. We don’t know how separate the 2 types of LTM are.
Using brain damage patients is a weakness as we do not know what they were like before the damage and we don’t know what the structural damage is until they are dead.(didn’t know what they were like before, just assume they had perfect memory etc)
4th type of memory ‘priming’ (there is a 4th type of memory, this theory does not account for this. ‘An automatic enhanced recognition system to specific stimuli’.
