Handwriting position and hemispheric asymmetry in right-handers.
Right-handers who write with an inverted writing posture (N = 8) were compared to right-handers who write in the normal fashion (N = 16) on tests of handedness and hemispheric asymmetry. Inverted writers showed the same laterality effects as normal writers for dot location and the recognition of visually-presented nonsense syllables. In dichotic listening, inverted writers were much more likely to show a left-ear superiority than were normal writers. They also were more strongly right-handed on a speeded performance test, but not in hand preference. This pattern is quite different from that obtained with left-handers, and suggests that the inverting handwriting posture has a different basis in right-handers than in left-handers.
