Type A Personality Characteristics and the Effect on Individual and Team Academic Performance

Type A personality has been conceptualized in part as high need for achievement combined with aggression, hostility, and self-esteem issues. In teams of undergraduate business students, high levels of Type A personality significantly correlated with high levels of depression and high levels of social monitoring; and negatively correlated with social desirability, communality, and individual performance across time. In team settings, the more Type A's were balanced in a team with low Type A's, the more there was team commitment and the more team synergy behaviors; while if teams had a greater number of Type A's, there was more individualistic behavior, and team project scores were lower.     

Supertaskers: Profiles in extraordinary multitasking ability

Theory suggests that driving should be impaired for any motorist who is concurrently talking on a cell phone. But is everybody impaired by this dual-task combination? We tested 200 participants in a high-fidelity driving simulator in both single- and dual-task conditions. The dual task involved driving while performing a demanding auditory version of the operation span (OSPAN) task. Whereas the vast majority of participants showed significant performance decrements in dual-task conditions (compared with single-task conditions for either driving or OSPAN tasks), 2.5% of the sample showed absolutely no performance decrements with respect to performing single and dual tasks. In single-task conditions, these “supertaskers” scored in the top quartile on all dependent measures associated with driving and OSPAN tasks, and Monte Carlo simulations indicated that the frequency of supertaskers was significantly greater than chance. These individual differences help to sharpen our theoretical understanding of attention and cognitive control in naturalistic settings.
