The purpose of the current investigation was to examine the age-related changes in the performance of the two hands on the Annett pegboard (Annett, 1970). The current study was part of a large-scale study investigating the development of unimanual and bimanual performance. Three hundred and two right-handed individuals participated in the present study, comprising five different age groups (3-5 year olds, 6 and 7 year olds, 8 and 9 year olds, 10-12 year olds, and 19-24 year olds). All participants completed the Waterloo Handedness Questionnaire and the standard Annett pegboard. Analyses revealed significant overall performance differences between the hands, as expected, where the right hand was significantly faster than the left hand. Additionally, significant performance differences between the hands were noted as a function of age. More specifically, the adults showed a much smaller performance difference between the hands than the other age groups. The results are discussed in light of current theories of the development of hand preference and manual asymmetry.
当前调查的目的是研究在安尼特钉板测试（安尼特，1970年）中双手表现的年龄相关变化。本研究是一项大规模研究的一部分，该研究旨在调查单手和双手操作能力的发展情况。302名右利手个体参与了本研究，他们分为五个不同的年龄组（3至5岁组、6至7岁组、8至9岁组、10至12岁组以及19至24岁组）。所有参与者都完成了滑铁卢利手问卷和标准的安尼特钉板测试。分析结果显示，正如预期的那样，双手之间存在显著的总体表现差异，右手明显比左手快。此外，还发现双手之间的表现差异因年龄而异。更具体地说，成年人双手之间的表现差异比其他年龄组小得多。我们根据当前关于手偏好和手部不对称发展的理论对结果进行了讨论。
