Heyman's view that addiction can be viewed as a natural outcome predictable by melioration and the matching law is provocative. Remaining to be explained more fully, however, are exactly how his view is an improvement on other reinforcement-based accounts. Included in these elaborations should be an account of how different “bookkeeping schemes” are developed and controlled and what new approaches to treatment and prevention of drug addiction are indicated.

It is difficult to accommodate compulsive drug use that destroys regulation by consequences in a unitary framework of melioration or maximization, especially as both are strategies of behavioral regulation. The “contradiction” of addictive behavior despite aversive consequences is an illusory issue because consequences that do not decrease addictive behavior cannot be considered punishing.

Heyman explains useful ways to bring addictive drug use under environmental control. We doubt that relapse is explained by drug features such as immediate reinforcement, clouding of judgment, and so forth. Relapse may require explanation in terms of enduring sensitization of incentive neural substrates, but even if its causal assumptions are wrong, Heyman's model makes useful predictions for behavioral control.

Transcendence, defined as the capacity to perceive the immediate stimulus environment in relation to long-range or abstract concerns, is a key aspect of self-control, and indeed self-regulation often breaks down because attention becomes focused exclusively on the immediate stimuli (i.e., transcendence fails). Factors that restrict attention to the here and now will weaken self-control, whereas factors that promote transcendence will enhance it. Guilt may be one example of the latter.

Contrary to his own perspective, Rachlin introduces a ghostly inner cost to explain the persistence of behavioral patterns and agency to explain their origins. Both inconsistencies can be set straight by taking account of history and a context larger than the pattern itself. Persistence is explained by stimulus control, if one assumes that defection from a pattern has stimulus properties and is punished. The origins of patterns are understood as an outcome of selection in the larger context of cultural or (...) biological evolution. (shrink)

Common folks “have” emotions and talk to others; and sometimes they make “their” emotions the topic of such talk. The emotions seem to be “theirs,” since they can be conceived of as private states ; and they can be topicalized, because we seem to be able to attribute or lend a conventionalized public form to some inner state or event. This is the way much of our folk-talk and folk-thinking about emotions, the expression thereof, the role of language in these (...) expressions, and communication in general are organized. However, as we have shown, such talk serves the purpose of communicating effectively and reaching mutual understanding. (shrink)
