One-handed weight discrimination was investigated as a function of hand, hand preference and hemispheric specialization. Differential thresholds (DLs) were measured for the left and right hands and left- and right-handed male and female subjects. DLs were found to be lower for the hand contralateral to the ear that proved superior in a verbal dichotic listening task. These results establish the existence of a manual asymmetry for the discrimination of lifted weight with the advantage accruing for the hand contralateral to the non-language cerebral hemisphere.
单手重量辨别能力作为手、利手和半球特化的函数进行了研究。对左右手以及左利手和右利手的男性和女性受试者测量了辨别阈（DLs）。发现在言语双耳分听任务中表现更优的那只耳朵对侧的手的辨别阈更低。这些结果证实了在辨别举起重量方面存在手动不对称，优势在于非语言脑半球对侧的手。
