Rachlin's view of self-control is rejected on the grounds that his arguments do not establish the possibility of abstract, external, stimulus patterns and that his experiments, although they show that pigeons and human beings do sometimes choose postponed rather than immediate gratification, do not challenge the commonly held view that internal factors are involved in the former choice.

The target article extends molar behaviorism in two positive ways: beyond average aggregates and beyond restricted laws of Although a molar framework based on purely overt events shows promise for advancing behavior theory, Rachlin's specific form of teleological behaviorism is in need of clarification.

The willingness to trade off large but ill-defined future consequences for immediate work characterizes social problems such as environmental sustainability. This commentary argues that important applications of behavioral models of self-control are being overlooked in the experimental literature. Tying the experimental literature to longterm health, environmental, and other risks makes the experimental work more germane, and raises new research questions for experimental modeling.

Operant psychologists are looking for alternatives to radical behaviorism. Rachlin offers teleological behaviorism, but it may pose as many difficulties as radical behaviorism. There is, however, a less drastic way to defend Rachlin's thesis of It portrays operant principles as relating distal efficient causes to behavioral effects.

The costliness of disrupting a pattern may not be a useful criterion for distinguishing between acts and patterns; there are instances in which omitted components of patterns are hard to detect (e.g., typographical errors), or in which distortions are easily introduced (e.g., slurred words in a trite phrase). Are there behavioral criteria for distinguishing between acts and patterns?

Rachlin overlooks that free will determines when and in what direction acts that appear impulsive will occur. Because behavioral patterns continuously evolve, animals are not guaranteed when they will, or how to, maximize larger-later reinforcements. An animal therefore uses self-control to emit free acts to vary behavioral patterns to optimize larger-later rewards.

Complex cases of self-control involve processes such as guilt-avoidance, inhibition, self-punishment, conscious thought, free will, and imagination. Such processes, conceived as internal mediating mechanisms, serve the function in psychological theory of avoiding teleological causation. Acceptance of the scientific legitimacy of teleological behaviorism would obviate the need for internal mediation, redefine the above processes in terms of temporally extended patterns of overt behavior, and clarify their relation to selfcontrol.

Self-control, so important in the theory and practice of psychology, has usually been understood introspectively. This target article adopts a behavioral view of the self (as an abstract class of behavioral actions) and of self-control (as an abstract behavioral pattern dominating a particular act) according to which the development of self-control is a molar/molecular conflict in the development of behavioral patterns. This subsumes the more typical view of self-control as a now/later conflict in which an act of self-control is a (...) choice of a larger but later reinforcer over a smaller but sooner reinforcer. If at some future time the smaller-sooner reinforcer will be more valuable than the larger-later reinforcer, self-control may be achieved through a commitment to the largerlater reinforcer prior to that point. According to some, there is a progressive internalization of commitment in the development of self-control. This presents theoretical and empirical problems. In two experiments temporal patterning of choices increased self-control. (shrink)

There seem to be two kinds of pain: fundamental pain, the intensity of which is a direct function of the intensity of various pain stimuli, and pain, the intensity of which is highly modifiable by such factors as hypnotism, placebos, and the sociocultural setting in which the stimulus occurs.

Maximization theory, which is borrowed from economics, provides techniques for predicing the behavior of animals - including humans. A theoretical behavioral space is constructed in which each point represents a given combination of various behavioral alternatives. With two alternatives - behavior A and behavior B - each point within the space represents a certain amount of time spent performing behavior A and a certain amount of time spent performing behavior B. A particular environmental situation can be described as a constraint (...) on available points (a circumscribed area) within the space. Maximization theory assumes that animals always choose the available point with the highest numerical value. The task of maximization theory is to assign to points in the behavioral space values that remain constant across various environmental situations; as those situations change, the point actually chosen is always the one with the highest assigned value.

The present intractability of and near intractability of make self-control a difficult topic.

Rachlin's view of self-control as a sequence or chain of behaviors is contrasted with traditional behavioral analyses of self-control which emphasize a simplistic interpretation of the hyperbolic function relating small-sooner (SS) and larger-later (LL) reinforcers to specific behaviors. The validity of Rachlin's teleological analysis is examined in relation to the acquisition and steady-state performance of self-control behaviors. Central to an analysis of self-control is the functional difference between behavior under the control of SS and LL reinforcers, because SS-reinforced behavior is (...) more complex due to temporal parameters.

Self-control is in the eye of the beholder. However, we speak of if a person has come to think conscious thoughts that change the motivational value of stimuli in the outside world. It is claimed that conscious thinking, and not habits bordering on compulsion, is behind self-control.
