Abstract
The aim of this study was to examine the differences in performance between extraverts and introverts, as well as between neurotic and stable subjects, in Fitts’ Tapping Task (FTT). Forty subjects classified into the four personality categories according to the EPI questionnaire (10 in each), performed twelve original FTT, with the task difficulty ranging from one to six bits.
The results showed the difference in performance between introverts and extraverts, but no differences were found between neurotic and stable subjects. Introverts achieved higher scores in easier tasks, while extraverts were better in more difficult tasks. The differences were attributed to summative effects of natural and task induced arousal, which resulted in an optimal level of cortical arousal in extraverts and hyper arousal in introverts at more demanding tasks. It was also found that stable introverts had the highest, and stable extraverts the lowest estimates of task difficulty assessment. Neuroticism, however, had no effects on the task difficulty.
