Proprioception as a Basis for the Temporal Anticipation of Motor Responses,

The present study attempted to distinguish between the proprioceptive Decay and proprioceptive Input Hypotheses of motor timing behavior. The hypothesis that an increased level of proprioceptive cues results in more proficient temporal anticipation was also tested. 90 male Ss were required to anticipate (no preview) the coincidence of a moving pointer and a stationary one. The timing response was executed with the right hand while 3 levels of proprioceptive cues were indirectly manipulated in the left arm. While results were unable to distinguish between the hypotheses, support was found for the hypothesis that an increased level of proprioceptive feedback administered during the interval can increase anticipatory response consistency.
