Q

outline the study conducted by Mcgeogh and Mcdonald

A

studied retroactive interference by changing amount of similarity between two sets of material. pps learned list of words with 100% accuracy , then learned new list either synonyms, atonyms, unrelated words, consonants, numbers and a control group.

Q

what were the findings of Mcgeogh and Mcdonald.

A

when asked to recall orginal list synonyms produced the worst recall , which shows interference is strongest when memories are similar.

Q

why is interference strongest with similar memories

A

could be due to previously stored information makes new similar information more difficult to store or new information may overwrite previous similar memories because of the similarity

Q

what is a study that supports interference occuring in the real world

A

Baddeley and Hitch asked rugby players to recall the names of teams they had played against during the season, players played for same time but number of intervening games varied due to injury. players who played most games had worse memory. Shows that interference occured due to the similarity of the memories being accessed, increases validity of theorey of interference as can operate in some real-world scenarios

Q

What is a limitation of investigating interference using lab studies

A

lab studies are highly controlled and can be manipulated to create the perfect conditions for interference to occur (two similar memories) however this is relatively rare to occur in everyday life so forgetting may be better explained by retrieval failure (lack of cues)

Q

what is another limitation of interference theorey

A

interference is temporary and can be overcome by cues, this is not predicted by the theorey.

Q

what does retrieval failure theorey imply

A

people forget due to an absence of cues, these are associated with memories when they are first placed with memory.

Q

what is the encoding specificity principle found by Tulving

A

states that a cue has to be both (1) present at encoding (2) present at retrieval if cues available at encoding and retrieval is different or one is abscent then forgetting will occur.
