Abstract

Simultaneous writing of both hands on a variable angle board showed large differences in performance between thoroughly right and left handed groups, the non-dominant hand producing mirror-script or mirror-patterning. A measure of amount of laterality by means of the angle at which mirroring occurred was shown. A recheck of Jasper's work on the phi-phenomenon as a measure of laterality gave corroborative results. The use of the Japanese Illusion as an indication of laterality was shown to be invalid. Failure of the non-dominant hand to reverse at a sound signal when both were describing opposite circles was demonstrated.
