Memory

Question 1

4 general theories of what memories are

Answer 1

1. records in the brain of varying strength
2. memories are stores in the brain
3. set of memory systems with different characteristics
4. as processes that are qualitatively different

Question 2

2 problems with strength theory

Answer 2

1. the idea that memories vary in only 1 dimension is wrong

2. diff. memoriy tests give different results for two encoded words

Question 3

what is 3 store model of memory

Answer 3

perceive>attend into STM>transfer into LTM

Question 4

evidence in favor of memory stores

Answer 4

1. aging - older people have poor LTM, but equal STM

2. amnesia - short and long term different

Question 5

3 probs with 3 store model

Answer 5

1. capacity of sTM - small
2. forgetting rate from STM depends on material
3. LTM is yet to be identified in any way

Question 6

4 aspects of memory systems

Answer 6

1. working mem. - info in “mind”
2. episodic mem - personal memories
3. semantic memories - facts
4. procedural mem - how to do something

Question 7

3 evidence in favor of systems

Answer 7

1. working mem = STM
2. people can learn procedural habits even if other mem impaired
3. semantic and episodic are differentially affected by age

Question 8

4 aspects of a processing approach

Answer 8

1. remembering as processing - activities not things
2. remembering lights up same areas as perceiving, attending
3. encoding = perceiving/comprehending
4. retreiving = recapitulation of encoding

Question 9

what happens to memory as we need to process more

Answer 9

remember it better

Question 10

2 areas of brain involved in mem

Answer 10

1. medial temporal - laying down perm. memories

2. frontal - control structures for encoding and retreiving

Question 11

what happens with laterality as age

Answer 11

older people use more bilateral
