Visual thresholds were determined in 3 types of <I>S</I> by a modified method of limits under 5 intensities of a 1 KHz pure tone. An analysis of variance of the data showed significant results for personality group and its interaction with intensity conditions. Under medium and strong intensities of tone, visual sensitivity “decreased” in introverts, and “increased” in extraverts with a greater increase at strong than medium intensities. In ambiverts it increased under strong intensity only. Non-significance of the intensity effect suggested visual dominance over auditory stimulation. Significant correlations between EPI E (but not N) scale scores and sensitivity change indicated the more extraverted the <I>S</I> is, the greater the increase in visual sensitivity. The results supported the proposed hypotheses.
