Two preliminary investigations were conducted on the error detection and error correction capabilities on a simple motor task of young, middle-aged and elderly adults. The error detection task assessed the subjects' ability to discriminate which of two test movements was the same as a previously presented criterion movement. The error correction task required subjects to correct an erroneous movement so that it was the same as a previously experienced criterion movement. Error detection performance increased for all age groups as the discriminability of the incorrect alternative on the test trial increased, but the middle-aged and elderly subjects demonstrated inferior overall performance relative to the younger subjects. Older subjects gave higher absolute error correction scores especially at the low error discriminability level, and the younger subjects did not show the negative correction bias (algebraic error) as suggested by the performance of the two older groups. The data were discussed in terms of Adams' closed-loop theory of motor memory.
针对年轻人、中年人和老年人在一项简单运动任务中的错误检测与纠错能力，进行了两项初步调查。错误检测任务评估了受试者辨别两个测试动作中哪一个与先前呈现的标准动作相同的能力。纠错任务要求受试者纠正错误动作，使其与先前经历的标准动作相同。随着测试试验中错误选项的可辨别性增加，所有年龄组的错误检测表现均有所提高，但中年和老年受试者的总体表现相对于年轻受试者较差。老年受试者给出的绝对纠错分数更高，尤其是在低错误辨别性水平时，而年轻受试者并未表现出如两个老年组表现所暗示的负向纠正偏差（代数误差）。依据亚当斯的运动记忆闭环理论对这些数据进行了讨论。
