Comparative analysis of handedness, hand-clasping and arm-folding frequencies in four groups of adult Israel 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.
对四组成年以色列犹太男性进行利手、扣手和交叉双臂频率的比较分析，这四组分别为东欧血统（N = 562）、中欧血统（N = 165）、中东血统（N = 191）和北非血统（N = 163），结果表明各组之间存在显著相似性。除中东组外，其他所有组均观察到较高比例的左利手个体。除中欧组以左手扣手为主外，其他组均以右手扣手和左臂交叉为主。当比较出生在东欧的个体与出生在以色列但父母为东欧血统的个体时，后者中左利手的频率要高得多。这可能归因于教育系统对第一组中左利手表达的抑制作用。还观察到了利手与扣手之间以及扣手与交叉双臂之间的关系。
