Velocity perception and proprioception
Kerr, Graham K. & Worringham, Charles J. (2002) Velocity perception and proprioception. In Gandevia, Simon C., Proske, Uwe, & Stuart, Douglas G. (Eds.) Advances in experimental medicine and biology: Sensorimotor control of movement and posture. Springer, New York, pp. 79-86.
Proprioceptive information related to position and velocity reaches conscious perception and appears to be processed simultaneously via separate perceptual channels. Determining the fidelity of velocity perception is difficult, however, because of the interaction of distance and timing information in its derivation. There is also a complex relationship between receptor discharge and kinematic variables and thresholds for detection of Proprioceptive information are increased during movement. Experiments determined the discrimination thresholds for different movement velocities when i) movement distance remained constant and duration varied; ii) movement duration remained constant and distance varied; iii) movement distance and duration were randomly varied. Discrimination thresholds increased as movement velocity increased. Velocity perception was more accurate when distance and timing cues were available, particularly at higher velocities. These results indicate that all available cues are used to make judgments of movement velocity.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
