Handedness and creativity in a sample of homosexual men.

A form concerning handedness, dyslexia, stuttering (self-report), and twinning was included in a study of sexual habits of homosexual men. Questions about interests in music, art, and creative writing were also included. A questionnaire was sent out to male homosexuals. Out of 391 returned forms, 363 were suitable for data processing. Analysis showed 13.9% reported writing with the left hand, 6.5% with stuttering, and 8.6% with dyslexia. The twin incidence was 1.2%. The creativity questions indicated a high music and painting activity. The results confirmed previous studies, showing a left shift in laterality and increased stuttering and dyslexia in the sample.
