Evaluation Of Types Of LTM

Question 1

Evaluation of types of LTM (+) supporting evidence

Answer 1

Strength of types of LTM is the supporting evidence of TULVING (1989). Participants injected with radioactive gold detected using gamma rays. Semantic memories increased blood flow posture region. Episodic memories increased blood flow frontal lobe. Supports idea there’s more than 1 type of LTM associated with different areas of brain - increased validity

Question 2

Evaluation of types of LTM (+) high control

Answer 2

TULVING (1989) study is a lab experiment ESTABLISHES CAUSE AND EFFECT. Control over extraneous variables. Strength - unlikely to be affected by confounding variables - internal vadilty.

Question 3

Evaluation of types of LTM (-) small sample size

Answer 3

TULVING’s research has low population validity. 6 participants is a very small sample size and therefore it’s unlikely that such a small sample provides good representation of the population. Difficult to generalise findings and reduces the confidence researchers can have in conclusion being valid - limited data. Tulvings study may not apply to all

Question 4

Evaluation of types of LTM (+) Clive Wearing

Answer 4

Still play piano but didn’t remember learning to play it. Playing the piano = procedural memory. Remembering piano lessons = episodic memory. This provides evidence that the claim that the LTM stores are seperate is valid
