This research compares the performance of a group of extraverts to a group of intraverts on a cognitive reasoning task. According to the theory of Hans J. Eysenck, one would expect that the intraverts would perform better than the extraverts on a task of massed reasoning. On the basis of scores on the Eysenck Personality Inventory and the Otis Lennon Mental Ability Test, a sample of 72 Ss were drawn from two undergraduate classes, Principles of Applied Learning and Human Development, at Western Kentucky University. Only Ss with extreme scores on the Extraversion scale E were selected, with each extravert and intravert being matched according to I.Q. Those Ss with high Neuroticism scores (N) were eliminated. After selection, the Ss were administered an abstract reasoning test. A comparison of the performance of the two groups revealed no significant differences.
