There is no agreement in the literature on whether there are associations among handedness, footedness, and eyedness among normal populations. These need to be clarified before studying abnormal populations. The majority of people have a right-sided preference for each of the three measures of laterality and hence some association is to be expected due to chance alone. Using three categories of laterality a statistical method which is new to these sorts of data has been used which allows the observed percentage agreement to be compared with that expected by chance for all three measures together (as well as in pairs). Its application to data from a sample of 192 young naval recruits suggests that there probably is a generalised dimension of motor laterality, at least among males.
关于正常人群中利手、利足和利眼之间是否存在关联，文献中尚无定论。在研究异常人群之前，这些问题需要先弄清楚。大多数人在这三种偏侧性测量指标上都有右侧偏好，因此仅由于偶然因素，也可以预期会存在某种关联。对于这三种偏侧性类别，使用了一种针对此类数据的新统计方法，该方法可以将观察到的百分比一致性与所有三种测量指标（以及两两之间）偶然预期的百分比一致性进行比较。将其应用于192名年轻海军新兵样本的数据表明，至少在男性中，可能存在一个普遍的运动偏侧性维度。
