memory - interference (explanations for forgetting) Flashcards
what is interference?
when two pieces of information disrupt each other and result in forgetting or distortion of memory
what is proactive interference?
an older memory interferes with a newer one
what is retroactive interference?
a newer memory interferes with an older one
what is the effect of similarity?
interference is worse when the memories are similar
PI - previously stored information makes new similar information more difficult to store
RI - new information overwrites previous similar memories
who researched the effect of similarity?
McGeoch and McDonald (1931)
how did McGeoch and McDonald (1931) study similarity?
gave each group of participants two list of words to learn
participants with more similarity between the two lists had the worst recall
strength - real world evidence
Baddeley and Hitch (1977) tested recall in rugby players
those who played the most games had the poorest recall as they had the most interference for memory
limitation - real-world interference is rare
conditions necessary for it in real life are very rare
highly controlled conditions of lab study means researcher can create ideal conditions for interference, but this isn’t reflective of real life
limitation - interference overcome by cues
Tulving and Psotka (1971) found interference is only temporary and can be overcome by cues - participants recall rose to 70% when given names of the categorised lists
limitation - validity issues
artificial materials - information to remember in everyday life is more meaningful
unrealistic procedures - in real life, information has to be recalled much later
