Abstract

The way in which readiness, intent and attitude affect motor responses to stimuli has been studied systematically by psychologists for over a century (rev: Gibson, 1941; Boring, 1957; Watson, 1963). Ach (1905) and Watt (1905) coined the term “Einstellung” (transl: attitude, set) for the brain processes underlying such phenomena. Since the late 1940’s, neurophysiologists have increasingly encountered neural behaviour consistent with the notion of set: task-dependent unitary discharge has been observed in the sensorimotor cortex (Evarts et al., 1984, premotor cortex (Mauritz & Wise, 1986), and association cortex (Mountcastle et al., 1975), and evidence for context-related transmission has been adduced for medial lemniscus (Ghez & Pisa, 1972) and spinal cord (Gurfinkel & Kots, 1966; Requin & Paillard, 1971).
