Differences in Primary Mental Abilities Between Musicians and Nonmusicians

Abstract. In the present study, psychometric performance on different aspects of primary mental abilities (verbal comprehension, word fluency, space, flexibility of closure, perceptual speed, reasoning, number, and memory) was compared in 70 adult musicians and 70 nonmusicians matched for age, sex, and level of education. No significant differences could be confirmed for either mean full-scale scores or for specific aspects of mental abilities, except Flexibility of Closure and Perceptual Speed. In both these subtests, musicians performed reliably better than nonmusicians. Musicians' superior performance may reflect nonaural aspects of musical ability or the result of long-term musical training. Eventually, a similar factor structure of intelligence does not support the notion of qualitative differences in the conception of intelligence between musicians and nonmusicians.
