The distribution of hand preference (self report) was studied in siblings and their parents originating from all parts of Turkey (N = 22,461). In total sample and siblings, there were significantly more right-handed women than men, and significantly more left-handed men than women--no significant sex difference for parents' handedness. The relative number for the right-handed parents significantly exceeded that for the right-handed siblings; the relative number for the left-handed siblings significantly exceeded that for the left-handed parents. It was concluded that there may be a sex difference in hand preference, but being only about 1% more left-handed men, and only about 1% more right-handed women; the right-handedness in new generation (siblings) is less than that in old generation (parents), due to freeing from cultural pressures against the left-hand use in everyday activities.
在来自土耳其各地的兄弟姐妹及其父母中（N = 22461），研究了用手偏好（自我报告）的分布情况。在总样本和兄弟姐妹中，右利手女性显著多于男性，左利手男性显著多于女性——父母的用手习惯不存在显著的性别差异。右利手父母的相对数量显著超过右利手兄弟姐妹的相对数量；左利手兄弟姐妹的相对数量显著超过左利手父母的相对数量。研究得出结论，用手偏好可能存在性别差异，但左利手男性仅比女性多约1%，右利手女性仅比男性多约1%；由于在日常活动中摆脱了对左手使用的文化压力，新一代（兄弟姐妹）的右利手程度低于老一代（父母）。
