individuals could not process the inherent semantic relatedness of the antonym-pairs, and thus failed to match the semantic context to that of the antonyms. This indicates deficits in semantic expectancy and post-lexical semantic processing in high risk subjects. Similar deficits have been reported; e.g., in a neuropsychological study, Drejer et al. (1985) found that HR adolescent sons of alcoholic fathers have poorer vocabulary and categorizing ability in comparison with sons of nonalcoholic fathers. Further, Ji et al. (1999) found no significant amplitude difference between category matching and nonmatching process in adult alcoholics, indicating deficient processing of sample stimuli in dealing with processing of matching stimuli.
