在早期的研究中，Dellatolas，Curt和Lellouch（1991）得出结论，用手习惯与出生季节无关。然而，对他们和其他数据集的事后探索表明，左撇子在3月至7月期间比8月至2月期间更普遍存在明显的趋势。本研究在大学生中前瞻性地检验了这一季节性假设。结果发现，在3月至7月期间出生的所有左撇子参与者的比例确实明显高于同期出生的所有右撇子参与者的比例。此外，模式的季节性影响利手并没有显着的女性和男性之间的差异。利手和出生季节之间的关系可能与其他因素的季节性变化有关，例如传染病的发病率。
In an earlier study, Dellatolas, Curt and Lellouch (1991) concluded that handedness is not related to season of birth. However, post-hoc exploration of their and other sets of data has shown that there is an apparent tendency for left-handedness to be more prevalent in the period March-July than in the period August-February. The present work tested this seasonal hypothesis prospectively among university students. It was found that the proportion of all left-handed participants who were born in the period March-July was indeed significantly greater than the proportion of all right-handed participants who were born in the same period. Furthermore, the pattern of seasonal influence upon handedness did not vary significantly between females and males. The relation between handedness and season of birth may be linked to seasonal variation in other factors such as the incidence of infectious agents.
