interference to forgetting Flashcards
what is proactive inference
its when the older memories distrupt the recall of the newer memories. the degree if forgetting is greater when the information is similar.
what is retroactive
when the newer memories distrupt the recall of older memories. the degree of forgetting is greater when the information is similar.
who did an investigation on the proactive interference
keepel and underwood
who did an investigation on retroactive interference
postman
what method did keepel and underwood use for their investigation and what was found
they got participants and presented them with a consent trigram and were asked to to recall them. participants were also give intervals such as counting backwards every three second ( 3, 9,12) and then the participants were asked to come back for the later stages and were given another trigram to remember. it was found that the recall of trigram first learned had interfered with the recall of newer trigrams.
what method did postman used for his investigation and what was found.
he used lab experiment and had spliced the participants into two group and the participants were given a list of paired words and were asked to recall those words. Group 1 was an experimenter group where the participant were given another list of words where the second paired words was different. Group 2 was the control r group they weren’t given any list. it was that the recall of control group was so accurate compare to the experimenter group as the words of second list shad interfered with the fist one because all participants were asked to recall the words form the first list.
what are the strongest of interference theory.
1- supported by postman’s research
2- supported by keepel and underwood’s research.
what is a limitation of interference theory.
is that it only explain forgetting for similar information such as why we find it difficult to learn French when we already know Spanish, which doesn’t happen very often. this is a limitation because it can’t explain most of the time that why forget information as it can be only applied to very specific situations. therefore its very limited as an explanation of forgetting.
