We extend to English Ito's (2001) demonstration of a hemispheric asymmetry in a false recognition and list-learning paradigm in Japanese. We show for English a significant interaction between the hemifield to which the probe word was presented and the probe type (non-studied but semantically related to the studied words versus non-studied and semantically unrelated to the studied words). The right hemisphere performed less well in rejecting the semantically related "lures"; the left hemisphere performed better in rejecting the semantically novel unstudied words. We discuss the results in terms of a model of fine semantic coding in the LH and coarse semantic coding in the RH, together with the dependence on memory probes that retain the representational signature of the hemisphere to which they were initially projected. Sex of the participants was also included as an independent variable; the results suggested that most of the effect lay with the female participants.
Some studies have reported a low rate of false recognition (FR) in individuals with autism spectrum disorder (ASD) relative to non-autistic comparison participants (CPs). This finding, however, has not always been replicated and the source of the discrepancy remains unknown. We hypothesised that poor episodic memory functions may account for this finding. We used an adapted version of the Deese, Roediger and McDermott paradigm which presents lists of words, pictures or word-picture pairs to obtain measures of performance which reflect episodic [hits and false alarms (FAs)] and semantic (FR) memory functions. Results showed a decreased rate of FR in ASD individuals with lists of words which rose above the rate seen in non-autistic CPs with lists of word-picture pairs. This increased rate of FR in ASD was accompanied by a parallel increase in hits and a decrease in FA which reached a similar level in the two groups. Poor episodic memory functions may prevent individuals with ASD from acquiring item information which in turn precludes the formation of semantic links between items. This could render them less prone to FR.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
