ABSTRACT: Reviews 4 interpretations of the manner in which sensory feedback may be involved in regulation of skilled performance. 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 (rG-sG) 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. It is concluded that: (a) evidence for rG-sG 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) limited available evidence is supportive of a contemporary version of IM; and (d) IM, SC, and CL can be regarded as serving complementary performance control functions.
