Memoria pe termen lung 2

Question 1

What is implicit memory?

Answer 1

Knowledge that can influence thought and behaviour without any necessary involvement of conscious awareness.
It is skills that you have leant.

Question 2

What are the 2 ways to measure implicit LTM?

Answer 2

Skill learning and priming.

Question 3

How is skill learning measured?

Answer 3

Through sensory-motor skills; perceptual skills and sequence learning.

Question 4

How is priming measured?

Answer 4

Priming is measured as the improvement in performance for previously presented or repeated stimuli as compared to stimuli presented for the first time.

Question 5

What is the evidence for distinct implicit and explicit LTM? (Corkin)

Answer 5

Skill learning:
Data from amnesic patient showed that they were still able to learn a mirror tracing task and rotary pursuit, despite having trouble with explicit memories.

Question 6

What is the evidence for distinct implicit and explicit LTM? (Warrington and Weiskrantz)

Answer 6

Priming:
At encoding amnesic patients were shown lists of words e.g. elephant
At retrieval they did not remember the word or even being presented with the word
However, word-stem completion task showed evidence of implicit learning as they were faster at completing words that they had previously seen compared to ones they hadn’t e.g. ele…………

Question 7

What is the difference between amnesic patients and patients with Parkinson’s?

Answer 7

Amnesic patients have intact performance on priming and skill learning (implicit) but impaired explicit memory.

Parkinson’s patients have intact explicit memory but impaired implicit memory.
