Researchers who aimed to see the effect of a second activity during encoding on the accuracy of memories
Study procedureof mcgeoch and mcdonald
1. 12 participants were shown lists of 10 words varying from synonyms, antonyms, words unrelated to the original ones, consonant syllables and three-digit numbers
2. Participants had to remember the words with 100% accuracy before being shown a new list
The more similar pieces of information you must recall, the less you remember
Memory is more affected by a second list when the activity is like the one you did before
Interference is at its strongest when the activity is like the one you did before
Strengths of the studyof mcgeoch and mcdonald
Techniques used were counterbalancing to ensure unbiasedness, giving different lists to all
The theory of interference includes validity due to the supported research
Weaknesses of the studymcgeoch and mcdonald
It lacked mundane realism as recalling lists is an artificial task and does not reflect how we use memory in our daily lives
