Tulving
Creation of Working Memory Model
Baddeley and Hitch
Study that showed dual task performance could be done
Baddeley et al.
Visual and verbal tasks could be done at the same time
Study on Interference
McGeoch and McDonald
Participants learn a list of words
Participants then placed into groups and asked to learn different lists of words, either similar to the original or not
Supporting Research for Inteference
Baddeley and Hitch
Rugby players asked to recall names of opponants
Evidence to show interference could be overcome with a cue
Tulving and Pskota
Participants told to remember words, and recall decreased as participants learned more words
Recall rose to 70% after they were given a cue
Another supporting study for interference involving drugs
Coenen and van Luijtelaar (1997)
Gave participants the drug diazepam which stopped new information from being learnt when taken after learning words
Encoding specificity principle
