Forgetting because one memory blocks another, one or both memories are distored or forgotten.
Mainly used as an explanation for forgetting in LTM.
When a old memory affects a newer memory.
(the degree of forgetting is greater when the memories are more similar)
A newer memory affects an old memory.
(the degree of forgetting is greater when the memories are similar)
key Study- McGeoch and McDonald.
Procedure- study of retroactive interference
- Changed the amount of similarity of the control set of material and the set the ppts learn after.
- ppts had to remember the control set 100% first
Sets of words: synonyms, atonyms, unrelated adjectives, numbers, nonsense syllables, no change
when ppts recalled the original set, the better performance depended on the nature of the second set. Worst performance- synonyms
This shows that interfernce is stronger when the memories are similar
