Abstract

The Edinburgh Inventory was used to assess handedness in a normal population. The incidence of strong right-handedness increased with age and the incidence of left-handedness fell with age, both significantly. A non-significant increase in the incidence of left-handedness in twins was observed. The difference in the incidence of left-handedness for males and females failed to reach significance but more males were left-handed than females. Any difference in the incidence of left-handedness between the sexes must be small (less than 1.5%) and this has major theoretical implications.

摘要

爱丁堡量表用于评估正常人群的利手情况。强右利手的发生率随年龄增长而增加，左利手的发生率随年龄增长而下降，二者均具有显著差异。观察到双胞胎中左利手的发生率有不显著的增加。男性和女性左利手发生率的差异未达到显著水平，但左利手的男性比女性更多。两性之间左利手发生率的任何差异必定很小（小于1.5%），这具有重要的理论意义。
