[Abstract]A symbol is defined as a species of sign. The concept of a sign coincides with Skinner's (1938) concept of a discriminative stimulus. Symbols differ from other signs in five respects: (1) They are stimuli which the organism can both respond to and produce, either as a self-directed stimulus (as in thinking) or as a stimulus for another individual with a predictably similar response from the recipient in each case. (2) they act as discriminative stimuli for the same kind of object for all members of the verbal community within which they function as symbols; (3) they acquire their properties by virtue of arbitrary social convention rather than any natural and intrinsic connection between the sign and what it is a sign of; (4) competent members of the verbal community can both produce the appropriate symbol in response to a naturally occurring sign of the presence of the object or a sample of the kind of object which the symbol stands for and select the appropriate object when presented with the symbol; (5) they form stimulus equivalence classes of the kind demonstrated in the matching-to-sample task (Sidman, 1971; Sidman and Tailby, 1982) both with other symbols having the same meaning and, more important, with the naturally-occurring non-symbolic signs of the presence of the object or kind of object which the symbol stands for.

[Abstract]The discredit into which the socialist ideal has fallen as a consequence of recent political events calls into question, not just the viability of a particular political and economic system but, the very idea that the social order can be improved by applying principles derived from the scientific study of human social behavior. Before the collapse of socialism, the idea of a science of human behavior, construed in biological terms as a branch of the science of the behavior of free-moving living organisms in general, had been undermined by Chomsky's (1959) repudiation of the behaviorist project to construct a science of language (verbal behavior) based on principles derived from the study of animal learning. I contend that only by reinstating the link between linguistics and the study of animal learning can confidence be restored in the possibility of a genuine science of human behavior with application to the problem of constructing a better social order.
