We have shown that a directional bias (D), previously thought to be unrelated to cerebral lateralization, is, in fact, intimately associated with it. In a group of fully consistent dextrals without familial sinistrality, the direction of lateral asymmetries depended upon the direction of D. Left-directed dextrals manifested the usual visual field advantages for linguistic and spatial material, while right-directed dextrals did not. D is therefore recommended as moderator variable for future studies of laterality.
我们已经表明，一种先前被认为与大脑侧化无关的方向性偏差（D），实际上与之密切相关。在一组没有家族性左利手的完全一致的右利手人群中，侧不对称的方向取决于D的方向。左向的右利手表现出对语言和空间材料通常的视野优势，而右向的右利手则没有。因此，建议将D作为未来侧化研究的调节变量。
