Recently Leviton and Kilty reported that the birth dates of left-handed girls in elementary school display a seasonal trend which peaks in November. We report here a failure to replicate this finding for 257 male and 323 female college students. Further, we have considered the likelihood that the original finding was due to sampling error rather than speculating that environmental factors associated with the season of birth are implicated in the etiology of left-handedness, as Leviton and Kilty have stated.
最近，列维顿和基尔蒂报告称，小学中左撇子女孩的出生日期呈现出季节性趋势，在11月达到峰值。我们在此报告，对257名男大学生和323名女大学生进行研究后，未能重现这一发现。此外，我们考虑了最初的发现是由于抽样误差造成的可能性，而不是像列维顿和基尔蒂所指出的那样，推测与出生季节相关的环境因素与左撇子的病因有关。
