What are thought to be the three main factors that demonstrate the differences between LTM and STM?
|
Capacity
Duration Encoding |
|
What are the three stages of the memory process?
|
Encoding
Storage Retrieval |
|
How many 'chunks' of information can the STM hold?
|
7 +/- 2 (5-9)
|
|
How long does information stay in the STM before it decays if not rehearsed?
|
18-30 seconds
|
|
Does the STM or LTM encode informatiom semanticly?
|
LTM
|
|
How does the STM encode information?
|
Acousticly
|
|
Who came up with the idea of chunks?
|
Miller (1956)
|
|
Who did a study into the duration of LTM?
|
Bahrick et al (1975)
|
|
What were the findings for the LTM duration study?
|
~90% recall for participants who had left school in the last 15 years
~80% recall for participants who had left school 48 years earlier |
|
What two processes are very important in the MSM?
|
Attention and Rehearsal
|
|
What are the names of the three memory stores that make up the MSM?
|
~Sensory memory
~Short term memory ~Long term memory |
|
How has the MSM been criticised?
|
~The model is oversimplified (The model lacks depth due to simplified STM)
~The model focus' too much attention on the importance of rehearsal (flashbulb memories support this argument) |
|
Who provides support for the multistore model and how? |
Glazner and Cunitz (1966) using research into the primacy and recency effect. |
|
Who came up with the idea that STM is active in the memory process, and what parts are there to this extended STM explanation?
|
Baddeley and Hitch (1974) argue that the STM is made up of three parts, the centeral executive, Phonological loop and Visuospatial sketchpad.
|
|
WMM stands for?
|
Working memory model
|
|
The phonological loop is split into two parts. What are the names of these two parts?
|
>Phonological store (Holds speech based information)
>Articulatory control system (Inner voice) |
|
What role does the Visuospatial sketchpad play in the WMM?
|
Holds visual information, processes visual information and processes spatial information
|
|
One strength of the WMM?
|
It provides a more detailed explanation of STM than the MSM as it can explain performance in Baddelys F study (evidence for)
|
|
One weakness of the WMM?
|
There is not much known about the CE (central executive) and it is difficult to test and quantify
|
|
Name three factors that affect EWT.
|
>Anxiety
>Misleading information >Age of witness |
|
Who did a meta analysis of studies that compared accuracy of children and adults in identifying suspects in an identity parade?
|
Pozzulo and Lindsay (1998)
|
|
What did Pozzulo and Lindsay find in their 1998 study?
|
>Children under 5 were less likely to identify the correct suspect
>No significant difference in identifying between children over 5 and adults |
|
Who did a lab experiment involving a weapon that showed the affect on EWT using anxiety/weapon focus?
|
Loftus (1979)
|
|
What were the findings of Loftus' Anxiety/weapon focus experiment?
|
Found 49% accuracy in the no weapon (pen and grease) condition
And... Found 33% accuracy in the weapon condition (blood stained knife) |
|
Who did a study into Misleading Information's affect on EWT?
|
Loftus and Palmer (1974)
|
|
How many MPH did participants guess the car was going in the Smashed and Contacted conditions? |
Smashed= 41mph Contacted= 32mph |
|
What method can be used to help improve witnesses recall of an event?
|
Cognitive Interview
|
|
Who provided evidence that supported the effectiveness of the cognitive interview?
|
Fisher (2002)
|
|
How much more accurate information did the cognitive interview give over the standard police interview in Fishers 2002 meta-analysis?
|
25-100%
|
|
What three strategies can be used for memory improvement?
|
>Mnemonics
>Organisation >Reversal |
