1
Q

describe the relationship between short term memory and long term memory

A

short term(working memory) is the gateway for information to enter long term memory

2
Q

what is declarative memory

A

knowledge and facts about the world

conscious recall

3
Q

what is non declarative memory

A

procedural memory- learning a procedure

4
Q

what is priming

A

improvement in identifying or processing a stimulus as a result of lots having been observed frequently

5
Q

what is the perceptual priming experiment

A

words presented and subjects asked to odentify them
some time later subjects presented with word stems and asked to complete them
priming is increased probability of choosing previously presented words (even if they were presented too quick to process consciously

6
Q

what is classical conditionin

A

previously neutral stimulus is paired with a positive stimulus that produces a response

7
Q

what is non associative learning

A

learning does not involve the association of two stimuli to illicit a bahvioural response

8
Q

what is habituation

A

decrease in level of response through repeated exposuure to a stimulus

9
Q

what is sensitisation

A

increase in level of response through the repeated exposure to a stimulus

10
Q

what are two examples of declarative memory

A

semantic and episodic

11
Q

what is semantic memory

A

memory for facts- norway has fjords

12
Q

what is episodic memory

A

memory for events- visiting the fjords in norway

13
Q

why is the study of episodic memory important

A

first symptom of mild cognitive impairnemtn which often leads to alzheimers
episodic deficits in huntingtins

14
Q

what is the main brain area associated with episodic memory

A

hippocampus

15
Q

what is the official definition of episodic memory

A

a system that recieves and stores information about temporally dated episodes or events and the temporal - spatial relations among events

16
Q

how have we tested episodic like memory in animals

A

birds prefer wax worms and store extra
birds choose worms when they are still fresh and not the ones they have learnt will have gone bad
they remember what, where and when

17
Q

why are birds not good model animals for psych

A

brains are v different to humans

very little is known about their behaviour and brains

18
Q

what was shown through experiments using rats for episodic memory

A

they remembered what and where food was but not when- contextual memory
