Q

3 main elements of memory

A

sensory store
short term store
long term store

2
Q

where are sensory stores kept

A

visual neurones

3
Q

what are short term stores

A

need to keep thinking about it to remember

4
Q

what is retrieval failure in LTM

A

information still held but can’t be retrieved

5
Q

what can make retrieving a memory harder

interference from other similar memories

6
Q

sematic encoding=

A

meaning of a word/ does it fit it sentence

7
Q

physical encoding

A

e.g capitals

8
Q

acoustic encoding

A

rhyme

9
Q

A

the environmental conditions where you learn makes a difference to how well you remember it

10
Q

what is state dependancy

A

you can recall information better when you feel the same as when you learnt it

11

two long term memory stores=

A

hippocampus

anterior temporal lobe

12

A

hippocampus

14
Q

what is episodic memory

A

unique experiences of people/place/object

15
Q

what is sematic memory

A

similarities between memories to create concepts

anterior temporal lobe

17
Q

what is important for memory consolidation

A

slow wave sleep

18
Q

how is episodic memory encoded in the hippocampus

A

neurones in the hippocampus bind together things in memory to re-instate the full picture of the memory
