Extraversion-Introversion and Neuroticism in Relation to Category Width

The study was concerned with finding significant differences between neuroticism and introversion-extraversion in relation to category width. With high, medium and low neuroticism for male and female introverts-extraverts, there was sex significance at the .05 level; without the medium group there was a sex significance at the .01 level. Males were found to be over-generalizes and to have wider categories than females. The medium male group resembled the female groups, which were in general more cognitively cautious than either the high and low male groups. Apparently there is not a linear continuum, as it usually assumed on the neuroticism scale for males at least with respect to the present task.
