Abstract

In this study, we attempted to maximize the likelihood of replicating Bakan's (1971, 1977a) observations that left-handedness was more probable in college students who were the progeny of "high-risk" births. To do this, the relationships between handedness and a combination of factors known to be associated with birth risk were computed. The observed relationships proved to be trivial and thus the validity of Bakan's hypothesis was questionned.

摘要

在本研究中，我们试图最大程度地复制巴坎（1971年、1977年a）的观察结果，即“高危”出生的大学生中左利手更为常见。为此，我们计算了利手与一系列已知与出生风险相关的因素之间的关系。结果发现这些关系微不足道，因此巴坎假说的有效性受到了质疑。
