The effects of musical accompaniment on two different visual information processing activities were examined in individuals of differing selected personality types. The Myers Briggs Type Indicator Form G was administered to classes of University students. From the results, four subgroups, the sensing-thinking, sensing-feeling, intuitive-feeling, and the intuitive-thinking were selected with 16 subjects each. Two different visual information processing experiments were conducted. Each experiment contained two parallel portions which were alternately presented with musical accompaniment and without musical accompaniment. Experiment 1 consisted of the two parts of the Group Embedded Figures Test (GEFT) by H. A. Witkin. Experiment 2 consisted of two parallel visual recognition tasks. Results of the two-way analysis of variance in Experiment 1 and Experiment 2 indicated no significant differences between the musical accompaniment treatments or among differing personality types in the number of items correct. However, a significant difference did exist in Experiment 1 in the number of referrals between the musical accompaniment treatments. Significantly less referrals to the figure to be traced in the GEFT were made with musical accompaniment than with no musical accompaniment. There were no significant differences among personality types in the number of referrals. (Author)
