Abstract

Investigations of human action have led to the conclusion that much action production can occur unconsciously. Behaviors such as reflexes and automatisms in neurological conditions reveal that action production can be mediated unconsciously. Less obvious, however, are the unconscious mechanisms associated with everyday voluntary actions. Voluntary action is a complex form of action that involves both unconscious and conscious component processes. This chapter reviews the unconscious components of voluntary action and then examines how these components interact with consciousness. The analysis includes treatments of Skinner’s influential “three-term contingency” and the phenomenon of effortless control. The chapter discusses the unresolved issues and paradoxes that are encountered when investigating action from a reductionistic standpoint in which there is no homunculus-like agent involved in voluntary action.
