This study explored the relationship between season of birth and handedness, taking into account gender and nationality variables. Young adults from three countries (2120 females and 1353 males; 877 Spanish, 2184 Italian, and 412 French), aged from 18 to 30 years, filled the Edinburgh Handedness Inventory (EHI). According to the literature, the percentage of left-handed participants in the whole sample was 9.30%. The distribution of left- and right-handed participants was not significantly different among the seasons of birth. The present data do not support a significant season of birth effect on handedness in young adults.
本研究考虑了性别和国籍变量，探讨了出生季节与利手性之间的关系。研究对象为来自三个国家的年轻人（女性 2120 名，男性 1353 名；西班牙 877 名，意大利 2184 名，法国 412 名），年龄在 18 至 30 岁之间，填写了爱丁堡手性量表（EHI）。根据文献，整个样本中左撇子参与者的比例为 9.30%。出生季节的左右利手参与者分布没有显著差异。本研究数据不支持出生季节对年轻人利手性的显著影响。
