两项空间能力测试，对459名14-15岁的中学生进行了心理折纸测试，并对428名大学生进行了Rev图形回忆测试，发现当偏好被分为左撇子和右撇子时，能力和手部偏好之间存在显着关系（Annett，1970 a）。在14-15岁和女大学生中，手的偏好与空间能力之间存在W型关系。得分最高的是中间的右撇子，有很强的左倾倾向。男大学生表现出线性趋势，空间能力最强的左撇子和下降，从左到右的水平的手偏好。当空间测试分数被认为是与手之间的差异，在技能的能力下降，增加右手被发现在右撇子和左撇子。根据右移理论（Annett，1972，1985），有证据表明，空间能力与rs +基因的存在有关，即使在单剂量（rs + -基因型）中也是如此，而那些缺乏该基因（rs - -基因型）的人在空间能力方面具有优势（Annett，1991 c）。
Two tests of spatial ability, mental paper folding given to 459 14-15-year-olds representative of the secondary school population, and recall of the Rev figure given to 428 undergraduates, found significant relationships between ability and hand preference when preferences were classified in subgroups of left- and right-handers (Annett, 1970a). In 14-15-year-olds and in female undergraduates there was a W-shaped relation between hand preference and spatial ability. The highest scores were in the centre for right-handers with strong sinistral tendencies. Male undergraduates showed a linear trend, with spatial ability highest in strong left-handers and declining from left to right across levels of hand preference. When spatial test scores were considered in relation to differences between the hands in skill a decline of ability with increasing dextrality was found in right-handers and in left-handers. In terms of the right shift theory (Annett, 1972, 1985), the evidence suggests that there are costs for spatial ability associated with the presence of the rs + gene, even in single dose (rs + - genotypes), and that those who lack the gene (rs - - genotypes) have advantages for spatial ability (Annett, 1991 c).
