Aesthetic preferences for photographs with the main focal content either to the left or right of the photograph's center were examined in right- and left-handed subjects. Verbal responses or manual responses were required. In one experiment with 261 introductory psychology student-subjects, left-handers more often preferred photographs with the more important part on the left (“left-geared”) than did right-handers. Exp. 2, involving 84 right-handed student subjects, showed that left-geared photographs presented on the left side were preferred more often than left-geared photographs presented on the right side, and left-geared photographs presented on the left side were more often chosen when a left-handed manual response was required. Interactions between handedness, position of the stimulus, language hemisphere, and response mode make it extremely difficult to ascertain whether the right hemisphere is really more involved in aesthetic decisions.
