On choice, preference, and preference for choice.

In this paper, we examine several common everyday meanings of choice, propose behavioral definitions of choice, choosing, and preference, and recommend ways for behavioral researchers to talk consistently about these concepts. We also examine the kinds of performance in the contexts of various procedures that might be appropriately described as a preference for choice. In our view, the most appropriate procedure for demonstrating preference for choice as a consequence is a concurrent chains method, in which choice is a reinforcer for an approach response. The single-stimulus procedure, however, is more appropriate for demonstrating preference for choice as an antecedent.
