Sažetak:
According to Eysenck's personality model, the efficiency of introverts and extraverts could differ in tasks, such as Fitts' tapping. Extraverts who have lower level of arousal, should be more efficient in more difficult tasks, while introverts should be maximally efficient in lighter tasks, due to the differencies in the task-induced arousal which is lower during lighter tasks and higher when performing more difficult tasks. According to this, introverts, in more difficult tasks, and extraverts in lighter tasks, would be submaximally efficient, because of hyperarousal in the former, and hypoarousal in the latter ones. The aim of this study, which included 40 subjects, selected from a sample of 290, and classified into the four personality categories according to the EPI questionnaire (10 in each), was to test this hypothesis. All the subjects performed twelve original tasks of Fitts' tapping, with the task difficulty ranging from one to six bits. The tasks included 25 alternative hittings of two targets, which width was 0.5, 1.0, 2.0 and 4.0 cm, while the movement amplitudes between the targets measured 4.0, 8.0 and 16.0 cm. The experimental situations amongst the subjects were rotated according to the Latin square principle. Obtained results confirmed the hypotesis that extraverts were, generally speaking, more efficient in more difficult tasks than introverts, while the introverts were more efficient in lighter tasks than extraverts. This is in accordance with Yerks-Dodson's low, where introverts reach optimal arousal level in lighter tasks and hyperarousal in more difficult tasks due to summative effects of the reticular arousal and task-induced arousal levels. Due to the same effects, extraverts have hypoarousal associated with lighter tasks and optimal level of arousal with more difficult tasks. When unstable subjects were taken out of the group of 40 subjects, there was no difference in efficiency between introverts and extraverts in light tasks, while extraverts were still more efficient in difficult tasks than introverts. Comparison of unstable extraverts and unstable introverts, however, showed the opposite effects, i.e. unstable introverts were more efficient in lighter tasks than extraverts. No difference was found between the two groups in more difficult tasks.
