ABSTRACT
Any attempt to understand the role of learning in interpersonal relationships must sooner or later employ a concept of reward, reinforcement, or incentive. The exchange theories discussed in the last chapter inherited much of their structure from Hullian or from operant theory. But the concept of reinforcement, although used in a hard-headed way in laboratory experiments is, as we have seen, liable to be somewhat diluted in studies of complex human actions. In this chapter we shall consider how some of the difficulties that arise might be met.
