ABSTRACT

A common way of describing speech, or any other kind of movement, is to attribute the output to the execution of a motor plan, into which some form of movable element is slotted. Of course, the argument for the existence of such a plan is circular. The fact that an orderly sequence of movements occurs leads to the assumption that there exists a representation at some level in the nervous system for that sequence. For example, the difference between perceptually fluent and dysfluent speech is attributed to the orderly or disorderly functioning of a speech plan. Thus, the order and regularity we observe in the real world is invested in an inaccessible construct; we make no explanatory gains by adopting such a strategy.
