How far can proprioception contribute to time keeping? To answer this question, a deafferented patient and neurologically normal subjects produced 1- or 5-sec durations in a sustained (continuous finger press) or discrete (two successive finger taps) manner, with and without Knowledge of Results. The findings were that: (1) proprioceptive afferents contribute to timing regulation in motor production of short durations; (2) this role can be rapidly compensated by Knowledge of Results; (3) the proprioceptive contribution is more important for sustained than for discrete performances; (4) stable performances are produced even when KR is withdrawn, suggesting familiarization with KR leads to the establishment of a mnemonic trace.
本体感觉对计时有多大作用？为了回答这个问题，一名传入神经被切断的患者和神经功能正常的受试者在有和没有结果反馈的情况下，以持续（持续手指按压）或离散（两次连续手指轻敲）的方式产生1秒或5秒的时长。研究结果如下：（1）本体感觉传入神经有助于短时长运动产生中的时间调节；（2）这一作用可通过结果反馈迅速得到补偿；（3）本体感觉的作用在持续动作中比在离散动作中更重要；（4）即使撤回结果反馈，也能产生稳定的表现，这表明熟悉结果反馈会导致记忆痕迹的建立。
