Bilateral reminiscence in inverted-reversed printing

Reported is a study of bilateral reminiscence in printing inverted-reversed alphabetic letters. Independent variables were the printing-Hand Sequence (left-to-right vs. right-to-left), and the Interpolated Activity (control vs. upright reading vs. inverted reading). These variables were factorially combined in a 2 × 3 design with 30 Ss per cell. On second-hand performance, the upright groups were found to be superior to the combined inverted and control groups under both sequence conditions. However, the inverted group was superior to the control group only in the left-to-right condition and not in the right-to-left condition. This latter result was discussed as possibly being due to the specialization of the cerebral hemispheres for certain types of processing activities. Implications of this hypothesis were pointed out for further research, and for possible mechanisms producing reactive inhibition in the central nervous system.
