P1 Section B (Memory) Flashcards
What is sensory register according to Atkinson and Shiffrin (1968)
According to Atkinson and Shiffrin (1968) the sensory register is a memory store which holds sensory events such as sights, smells and noises.
What’s the duration of sensory register
Duration of sensory register is 2 seconds
What’s capacity of sensory register
Capacity of sensory register is over a million - large
How is sensory register information coded
Sensory register information is coded acoustically and visually.
What is duration of short-term memory
Duration of short-term memory is around 15 to 30 seconds
What’s capacity of short-term memory according to Miller (1956)
capacity of short-term memory is 7 +/- 2 according to Miller (1956)
How is short-term memory information coded
Short-term memory information is coded acoustically
What’s duration of long term memory
The duration of long term memory is 50 years and above
What’s capacity of long-term memory
Capacity of long-term memory is infinite
How is long-term memory information coded
Long-term memory information is coded semantically
What’s the belief that Multi-store memory model is based on according to Atkinson and Shiffrin (1968)
according to Atkinson and Shiffrin (1968) the belief that Multi-store memory model is based on is we process memories like computers process information
How does information move from sensory register to STM
Information moves from sensory register to STM by attention
How does information move from STM to LTM in the multi-store model
Information moves from STM to LTM in the multi-store model by memory consolidation which is rehearsal
How did Milner et al (1966) support that LTM had different stores
Milner et al (1966) supported that LTM had different stores by finding patient HM who underwent lobectomy for epilepsy could learn motor skills (which is procedural memory - part of LTM), but could not recall the tasks he completed to learn these motor skills (episodic memory - part of declarative LTM)
What was Tulvings (1985) explicit LTM memory
Tulvings (1985) explicit LTM memory was memories that we try to consciously recall eg facts. Explicit memory is spilt into semantic and episodic memory
What is Tulvings (1985) explicit semantic memory
Tulvings (1985) explicit semantic memory is knowledge of language, concepts and facts and words
What is Tulvings (1985) explicit episodic memory
Tulvings (1985) explicit episodic memory is knowledge of personal events we’ve been experienced
What is Tulvings (1985) procedural or implicit memory
Tulvings (1985) procedural or implicit memory is behaviours such as riding a bike
Glanzer and Cunitz (1966) serial position effect - method
Glanzer and Cunitz (1966) gave participants and list of words to memorise and then recall as many as possible
Glanzer and Cunitz (1966) serial position effect - results
Glanzer and Cunitz (1966) found that participants could recall words given at the beginning because they had been rehearsed in LTM (primary effect) and words at the end because they were still in the STM (recency effect) but hardly those in the middle.
What does Glanzer and Cunitz (1966) serial position effect support
Glanzer and Cunitz (1966) serial position effect supports the idea that the LTM and STM are different and also the fact rehearsal is required in multi-store model
What is a weakness of Glanzer and Cunitz (1966) serial position effect
A weakness of Glanzer and Cunitz (1966) serial position effect is it lacks ecological validity since it’s not how memory is used in real life
How does information move from the LTM to STM in the multi-store model
Information moves from the LTM to the STM in the multi-store modal by retrieval
How did Jacobs (1887) find digit span for capacity
Jacobs (1887) found digit span for capacity by asking participants to recall digits, starting from 4 and then adding another digit each time and found that the mean span for digit recall was around 7
How does Jacobs (1887) study lack temporal validity
Jacobs (1887) study lacks temporal validity as it was done a long time ago and early psychology lacked control so participants might’ve been distracted or tired so didn’t perform well
What did the Petersons (1959) find about duration of STM
Petersons (1959) found about duration of STM that duration was around 18-30 seconds unless repeated over and over again
What is a limitation of the Petersons (1959) duration study
A limitation of the Petersons (1959) duration study is that it lacks ecological validity as the material asked to recall was artificial, meaningless three-letter trigrams and so it can’t be extrapolated to all stimuli as short-term memory may be longer for more important information
What did Bahrick (1975) find about LTM (yearbook)
Bahrick (1975) found that LTM has a long duration as people were able to remember people from their school yearbook after 48 years
Strength of Bahricks (1975) study on duration of LTM
Strength of Bahricks (1975) research is that it has high external validity as it is a meaningful stimulus remembering people
Weakness of Bahricks (1975) study on LTM duration
Weakness of Harry Bahricks (1975) study on LTM duration is that confounding variables such as the fact participants may have been in recent contact with people from the yearbook weren’t controlled
How is information stored in sensory register (multi-store model)
Information is stored in the sensory register as either iconic memory (visually) or echoic memory (acoustically)
How does Baddeley support the multi-store model of memory (mix-up)
Baddeley supports the multi-store model of memory by finding that we mix up words with similar sounds when we’re using our STM but mix up words with similar meanings when using LTM - showing STM stores acoustically and LTM stores semantically
How does Craik and Watkins (1973) criticise the MSM (two types of rehearsal)
Craik and Watkins (1973) criticise the MSM by saying there is two types of rehearsal and to move information from STM to LTM, elaborative rehearsal is needed because maintenance rehearsal just keeps information in the STM for longer
How does Tulving (1985) criticise the MSM
Tulving (1985) criticises the MSM by saying that it is too simplistic and inflexible
How does neuroimaging support Tulving (1985) semantic and episodic memory
neuroimaging supports Tulving (1985) semantic and episodic memory by finding that when using semantic memory, the left side of the prefrontal cortex was active and when using episodic memory, the right side of the brain was active
How does Cohen and Squire criticise Tulving’s (1985) episodic and semantic memory
Cohen and Squire criticises Tulving’s (1985) episodic and semantic memory by saying that episodic and semantic fall under the same store called declarative memory so there are two types of long term memory - procedural and declarative
What was Baddeley and Hitch’s view on memory
Baddeley and Hitch’s view on memory was that memory was a number of different stores
What is Baddeley and Hitch’s memory model called
Baddeley and Hitch’s memory model is called the working memory model
What are the five parts of the working memory model
the five parts of the working memory model are the central executive, phonological loop, visuospatial sketchpad, episodic buffer and long term memory
What is the job of the working memory model’s central executive
The job of the working memory model’s central executive is to decide how resources are allocated like deciding which issues need attention
