Memory Pt1 Flashcards
Does anxiety have negative effects on recall
Johnson & Scott
Found that 49% who saw the man with a pen could identify
Only 33% who saw the man with a knife could identify
Therefore suggest anxiety hinders recall
Does anxiety have any positive effects on recall
Yuille & cutshall:
Suggest anxiety improve recall
Evaluate interference theory
Mcgeoch & McDonald found the interference is stronger when memories are similler = recall fell to a mean of 1.5 when synonyms were used
Evaluate retrieval failure
Godden & Baddeley found recall was 60% better when conditions were the same at encoding and recall
However there were only 16 participants therefore unrepresentative
What supporting research is there of the working memory model
KF found he could not remember auditory info but could remember visual
What is a weakness of the working memory model
Criticism of the supporting research is that it is not generalisable
How can leading questions effect the accuracy of eye witness testimonies
Loftus and palmer:
45 students were asked how fast the car was going when it bumped/smashed/ collided/ contacted/ hit the car
Verb smashed: 40.5mph
Verb contacted: 31.8 mph
How can post event discussion effect accuracy of eye witness testimonies
Gabbert et al:
Watched a video
Memory contamination
Memory conformity
What is the yerkes Dodson law
The idea that there is a optimum level of arousal/anxiety
Who came up with the multi store model of memory
Atkinson and shiffrin
What is a strength of the multi-store model of memory
Supporting research: case of HM, had hippocampus removed due to epilepsy surgery
What is a weakness of the multi store model of memory
Opposing research : case of KF, could recall visual not auditory
What research has been done into coding
Baddeley suggest STM I’d acoustically dissimilar
And LTM is semantically dissimilar
What is a weakness of Baddeley research into coding
Stimuli(word list) is artificial
Lacks ecological validity
What research has been done into capacity
Jacobs - digit span = believed the mean digit span was 3 and 9
Miller disagreed = 7+/-2. Chunking
