Explanations of Forgetting: Interference Flashcards
what is interference used to explain?
forgetting in LTM
what are the types of interference?
- pro-active interference
- retro-active interference
what is pro-active interference?
an older memory disrupts a newer memory
what is interference?
two piece of information disrupt each other, resulting in the forgetting or one or both information or distortion of memory
what is retro-active interference?
newer memory disrupts older memory
what is the effects of similarity?
in both PI and RI, interference is worse when the information is similar
who were the researchers involved in the effects of similarity?
McDonald and McGeoch
what is the research involved in effects of similarity?
- ppts had to learn a list of 10 words until they could remember to 100% accuracy
- they then learned a new list
- there were 6 groups: synonyms, antonyms, words unrelated to original ones, consonant syllables, 3digit numbers and no list
what were the findings of the effects to similarity study?
- when ppts were asked to recall original lists of words, the most similar materials produced the worst recall
- this shows interference is strongest when memories are similar
how do we explain the effects of similarity?
- PI = previously store information makes new similar information more difficult to store
- RI = new information overwrites previous similar memories
what are the evaluations of interference?
+ evidence of interference effects in more everyday situations
- interference is temporary and can be overcome by using cues
+ evidence of retrograde facilitation
