A recent article (C. Gibson et al., Brain and Cognition (2009) 69:162-69) reported the results of a study on creativity in musicians. They studied a group of 20 musicians (and a control group of 20 non-musicians from the same university), with the two groups matched for age, education, , SAT scores, and high school grades. Among the more interesting findings:
- Musicians scored higher on verbal IQ and full scale IQ
- Musicians scored higher on the Gough Personality Scale (a measure of creativity)
- Musicians scored higher on the Schizotypal Personality Questionnaire in general, including the Cognitive-Perceptual subscale (which measures "perceptual aberrations and "magical thinking") and the Disorganization subscale (which is linked to odd behavior and speech), but not the Interpersonal subscale (which indicates reduced social and emotional functioning). The scores, however, were not high enough to be considered clinical.
- Musicians scored higher on other tests of creativity (that were not related to music)
So again, music is good for you. Just don't listen to those voices in your head too closely...
