The relationship between consistency of hand preference, left hemispheric specialization, and cognitive functioning was examined in an ongoing longitudinal investigation. Children were classified as consistent or inconsistent in their hand preference across 5 assessments from ages 18 to 42 months. Findings demonstrated that (a) this early classification continued to reveal differences in cognitive functioning from 10 to 17 years but only for girls, (b) consistent girls' performances were continually higher relative to the inconsistent girls on measures of verbal intelligence and reading achievement, (c) differences between the female groups were specifically related to left-hemispheric language specialization, and (d) one factor influencing the consistent girls' development may be the amount of reading exposure received during infancy.
本纵向研究旨在考察惯用手一致性、左半球偏侧化和认知功能之间的关系。在 18 至 42 个月大期间的 5 次评估中，对儿童的惯用手一致性进行分类，分为一致性或不一致性。研究结果表明：(a) 这种早期分类在 10 至 17 岁时仍能揭示认知功能的差异，但仅限于女孩；(b) 在言语智力和阅读成绩方面，一致性女孩的表现始终高于不一致性女孩；(c) 女性群体之间的差异与左半球语言偏侧化具体相关；(d) 影响一致性女孩发展的一个因素可能是婴儿期接受的阅读量。
