(NON)ISSUES OF INFINITE REGRESS IN MODELING MOTOR BEHAVIOR

In the past, infinite regress criticisms that have been raised about m odels of motor behavior have been reserved for executive-type models ( e.g., Beek. & Meijer, 1988). On the basis of Godel's (1930/1986) proof that an algorithm cannot prove its own validity, the authors reason t hat executive-as well as self-organized-type explanatory models of mot or behavior have infinite regress difficulties. The conclusion offered in the present article is that judgments on a model's theoretical imp ortance should be based not on issues of infinite regress but on other relevant characteristics, such as its propensity for falsification (P opper, 1959).
