An analysis of concept learning: simple conceptual control and definition-based conceptual control.

Concept learning can involve either contingency shaping of stimulus-class discriminations or the application of definitions of the concepts. Experimental behavior analysts have studied contingency shaping, whereas educational psychologists have studied definitional concept training. In this paper, we analyze definition-based concept learning in terms of stimulus-response chains. Then we apply this chaining analysis to principles of instruction proposed by educational psychologists. These principles include (a) stating the definition in terms of critical and variable attributes, (b) using examples and nonexamples, (c) using a rational set of examples and nonexamples, (d) presenting coordinate concepts simultaneously, and (e) presenting the next instance based on the learner's previous error.
