What is the Multi Store Model?
Memory is not a single process but involves more than one stage and more than one kind of memory. There is a flow of information through the memory system. Sensory memory -given attention/decays-> STM (temporarily)-->LTM (permanent storage)

What is Encoding?
Process of changing information to be remembered into a form which makes it suitable for the memory store to deal with.
2 of 17
What is Capacity?
The amount of information that can be held within the memory store.
3 of 17
What is Duration?
How long information can be held in each store for.

What is the capacity, duration and encoding for all 3 stores of memory?
Sensory: 12 pieces, 0.5 seconds, impressions. STM: 7+/- 2 items, 20 seconds, acoustically. LTM: unlimited, number of mins, years or lifetime, semantically.

What are the levels of processing (Craik & Lockhart)?
~Shallow (basic) dependent on the appearance of the item (iconic) e.g is the word in capital letters. ~Phonemic (medium) sound of the item (echonic) e.g does the word rhyme with train. ~Semantic (deep) meaning of item e.g is the word a type of friut

What is the Working memory model?
Developed by Baddely and Hitch on the STM. Process that integrates both auditory & visual. Through 'inner eye & voice' the visuospatial sketchpad & phonological loop work as slave systems to central executive. Episodic buffer=combines info (temporary

Evaluate the working memory model
~ Application, diagnose learning difficulties in children. ~ Listening american football on the radio impaired driving ability while listening to music doesn't, vssp cant cope with 2 tasks simultaneously (game & roads)~PET scans~neglects other senses

What is the Yerkes-Dodson Law?
There is a relationship between anxiety and performance on tasks like remembering events. If anxiety is low performance is poor, when anxiety is high performance is poor, it is a its best when at medium which makes them very reliable at EWT.

What is a cognitive interview?
This is used by police in an attempt to gain maximum info from witnesses. ~Report everything even if it is unrelated (retrieval cue) ~Re-create the context, imagine yourself back at scene. ~ Remember event in different orders. ~ Change perspective.
10 of 17
What are the criticisms of cognitive interview?
~alot is irrelevant information. ~needs more time than is available to police. ~ unsuitable for young children. ~doesnt work to identify suspect. ~context reinstatement & report everything most effective.
11 of 17
What are the levels of processing?
Craik and Lockhart claim that there are 3 levels at which we process information. Structural - thinking about what something looks like. Phonetic - thinking about what something sounds like. Semantic - thinking about the meaning.
12 of 17
What is method of loci in memory improvement?
Plan a route around home and create visual images that link with items you want to remember e.g bread in bed.when in the shop visually walk round the house.
13 of 17
Method of loci - evidence for and limitations?
Groniger - more useful than just learning words and stays in memory for longer. ~only remember a short amount of items. ~difficult to think of many everyday situations which it is useful. ~lacking ecological validity.
14 of 17
What is categorical clustering? evidence for and limitations?
They are divided up into meaningful clusters. Bousfield- recall they remembered things in clusters so they had organised things to aid recall. Lack ecological validity as we are not asked to recall long words lists in real life.
15 of 17
What is hierarchical organisation? evidence for and limitations?
Use of hierarchies as well as categories. Bower - 112 words presented randomly or in conceptual hierarchy, 45% higher recall for ch than random. lacks ecological validity.
16 of 17
What is imagery? evidence for an limitations?
encourage people to form images. Bower - 80% remebered in group that were asked to form images to link the two words of each pair. 45% in condition where asked to just learn them. Cant be generalised as no ne learns in the same way.
