M5. EFF: Interference

Question 1

Interference

Answer 1

• the recall of one memory blocks the recall of another
• causing: forgetting, distorted perceptions of memories

Question 2

Retroactive Interference

Answer 2

• NEW memories block recollection of old memories
• McGeoch et al. : P’s in 6 groups to recall lists of words (synonyms, antonyms, words unrelated to original list, 3 digit numbers, consonant syllables, NO new list - control)
• those who learnt synonym list recallled 3.1 less correct items on average (compared to control)
• supports idea that extent of forgetting is larger with two similar items

Question 3

Proactive Interference

Answer 3

OLD memories block recollection of new memories

Question 4

• Eval: lacks eco-validity

Answer 4

• artificial stimuli used in tasks (lists of words with no meaning to participants)
• LOW MUNDANE REALISM
• likely to learn lists of meaningful words in real life; which we also draw links upon
• therefore lacks ecological validity

Question 5

+ Eval: Lab Experiments

Answer 5

• extraneous and confounding variables (such as excess noise that may interfere with recall) removed; meaning that a causal relationship can be drawn
