Handedness, hand-clasping and arm-folding in Israeli males

Abstract
Comparative analysis of handedness, hand-clasping and arm-folding frequencies in 4 groups of adult Israeli Jewish males of East European origin (N = 562). Central European origin (N = 165), Middle Eastern origin (N = 191) and North African origin (N = 163), indicates a significant similarity between the groups. A high percentage of left-handed individuals was observed in all groups except the Middle Eastern one. Right-hand clasping and left arm-folding predominated in all but the Central European group in which left hand-clasping predominated. When a comparison is made between individuals born in Eastern Europe and those born in Israel to parents of East European origin, the frequency of left handedness was considerably higher among the latter. This may be attributed to an inhibitory effect of the educational system on the expression of sinistrality in the first sub-group. Relationships between handedness and hand-clasping and between hand-clasping and arm-folding was also observed.
