Neuroticism and extraversion as predictors of negative and positive emotional information processing: comparing Eysenck's, Gray's, and Newman's theories

Authors


Abstract

This study compared how extraversion, neuroticism, and extraversion × neuroticism are related to processing of pleasant and unpleasant emotional information as predicted by Eysenck's, Gray's, and Newman's theories. Initially, the participants' levels of extraversion (as measured by the sociability subscale) and neuroticism were assessed with Eysenck's Personality Inventory. They were then tested individually. After completing a questionnaire of current positive and negative moods, they completed three tasks measuring processing of pleasant, unpleasant, and also neutral information. The results showed that extraversion was associated positively with the processing of pleasant information, while neuroticism was associated positively with the processing of unpleasant information. These findings support predictions from Eysenck's theory. Copyright © 2002 John Wiley & Sons, Ltd.
