Unitisation Flashcards
Squire et al (2004)
Many studies still found that item associations (which require familiarity) could still be made for people with lesions in the perirhinal cortex
Troubles forthe BIC model
Haskins et al (2008)
Did a novel compund task (unitisation) and compared it to a sentence task (item independent)
Found that items in the novel compound task were encoded as one item which is why people could still recall unitised items despite damage to the perirhinal cortex
Assumed that recollection processes are assocaited with unitised associations
Jager et al (2006)
Found familiarity related ERP to be assoicated with unitised associations
Late positive complex ERPs were only found for non-unitised associations
Familiarity only supports associative unitised recognition and recollection only supports non-associative recognition
Rhodes and Donaldson (2008)
Semantically related words were more likely to generate familiaity related ERPs if interactive imigary as opposed to item imigary was used
Bader et al (2010)
Support Rhodes and Donaldson (2008)
Familiarity related ERPs only occur for old unitised pairs
Recollection related ERPs only occur for old non-unitised pairs
Familiarity based associative recognition occurs for unitised pairs and recollection based assocaited recogntion occurs for non-unitised associative items
Zheng et al (2015)
Critiqued research for comparing ERPs between compounds and item independent dessigns instead of the difference when identifying intact, re-arranged and new pairs in associative recognition tests
Found that both recollection and familiarity based ERPs were greater for the identification of intact and re-arranged pairs as opposed to unrelated word pairs
Implies that both familiarity and recollection are required for associative recognition
Shao et al (2015)
Found the opposite to Rhodes anf Donaldson (2008)
Recollection based associative recognition was more likely based on interactive imigary tasks than on compound tasks
Recollection based associative recognition was related to decrease in familiairity based associative recogniton becasue when the memory trace is encoded in a way that’s easier to recall, there is no need to recognise the item as familiar
Tibon and Henson (2015)
Critiques Shao et al (2015)
Found that it found contradicting evidence to Rhodes and Donaldson (2008) due to differences in the experimental procedure
It may not be that recollection decreases familiairity but if familiarity is readily available (as it is in Dual Process Theory) then why would someone need to engage in effortful processing?
