Sensory Feedback Mechanisms in Performance Control
نویسنده
چکیده
Four interpretations of the manner in which sensory feedback may be involved in regulation of skilled performance are reviewed. For the serial chaining (SC) and closed-loop (CL) mechanisms, response selection is assumed to occur on the basis of peripheral feedback from preceding correct and incorrect responses, respectively; for the ideo-motor ( IM) and fractional anticipatory goal response (ro-so) mechanisms, it is assumed that a response's performance is directed by anticipatory representation of its own feedback or of feedback from the reaction to a goal to which the response leads, respectively. Among the conclusions of the review are (a) evidence for re-so as a mechanism for specific response selection, as opposed to generalized facilitation or inhibition of instrumental performance, is lacking; ( b ) the notion of a mechanism for comparison of actual feedback with images of desired feedback is not essential for explaining error-correction performance which is characteristic of CL; (c) despite severe criticism by twentieth century behaviorists, the limited available evidence is quite supportive of a contemporary version of I M ; and (d) IM, SC, and CL can be regarded as serving complementary performance control functions-selection or "programing" of voluntary performance ( IM) , coordination of action within invariant sequential performances (SC), and coordination of action within sequential performances requiring correction responses to error stimuli (CL).

Neural control and adaptive neural forward models for insect-like, energy-efficient, and adaptable locomotion of walking machines
Living creatures, like walking animals, have found fascinating solutions for the problem of locomotion control. Their movements show the impression of elegance including versatile, energy-efficient, and adaptable locomotion. During the last few decades, roboticists have tried to imitate such natural properties with artificial legged locomotion systems by using different approaches including mac...
متن کاملContinuous theta-burst stimulation to primary motor cortex reveals asymmetric compensation for sensory attenuation in bimanual repetitive force production.
Studies of fingertip force production have shown that self-produced forces are perceived as weaker than externally generated forces. This is due to mechanisms of sensory reafference where the comparison between predicted and actual sensory feedback results in attenuated perceptions of self-generated forces. Without an external reference to calibrate attenuated performance judgments, a compensat...

متن کاملMovement goals and feedback and feedforward control mechanisms in speech production.
Studies of speech motor control are described that support a theoretical framework in which fundamental control variables for phonemic movements are multi-dimensional regions in auditory and somatosensory spaces. Auditory feedback is used to acquire and maintain auditory goals and in the development and function of feedback and feedforward control mechanisms. Several lines of evidence support t...
