It was hypothesized that, since verbal and spatial ability seem to be lateralized (left for verbal, right for spatial), in any dichaptic task individuals with high spatial ability will do best with their left hands and those with high verbal ability best with their right hands. Conversely, scores with high spatial ability should make more errors with their right hands and highly verbal people more errors with their left hands. Some evidence was found to support these hypotheses for males, but for females the relationships seemed more complex. Possible explanations and implications of the findings are discussed.
研究假设，由于语言能力和空间能力似乎具有单侧化特点（左脑负责语言，右脑负责空间），在任何双手分别触摸的任务中，空间能力强的个体用左手表现最佳，语言能力强的个体用右手表现最佳。相反，空间能力强的个体用右手犯错更多，语言能力强的个体用左手犯错更多。研究发现了一些证据支持男性的这些假设，但对女性而言，这种关系似乎更为复杂。本文讨论了这些发现的可能解释及其意义。
