who is the main study?
McGeoch & McDonald
McGeoch & McDonald - aim
To investigate if similar memories cause greater interference in different memories
McGeoch & McDonald - method
- ppt given list A - learn to 100% accuracy
- split ppts into 6 random groups - given list B
(except control group) - Remember list A + recall
What were the types of list B’s given to participants?
most similar
- synonyms to the originals
- antonyms to the originals
- unrelated words
- nonsense syllables
- 3 digit number strings
least similar
McGeoch & McDonald - results
increasing similarity - worser the recall
- mean no. item recalled in ‘numbers’ group was 37%
- mean no. recalled in ‘synonyms’ group was 12%
