Abstract

Extraversion, arousal and time of day have characteristic interactive effects on semantic priming of lexical decision. Matthews and Harley's activation-sensitization hypothesis attributes these effects to individual differences in the sensitivity of units in an interactive activation network. The hypothesis predicts that the characteristic arousal-dependent effects on extraversion of priming should be found only when priming depends on pre-lexical activation processes, but not on later post-lexical processing. An experiment (N = 64) was conducted in which the roles of pre- and post-lexical processing in priming were varied by manipulating the confusability of words and non-words. The characteristic interactive effect of extraversion, arousal and time of day was found only when words and non-words were non-confusable, so that priming depended mainly on pre-lexical processing. This finding supports the Matthews and Harley hypothesis, and indicates the importance of task parameter selection in investigating arousal-dependent effects of extraversion on performance.
