The influences large corporations have on the lives of most citizens is huge. In the developed world the relationships between corporations and citizens is generally close, with top corporate managers making decisions that shape the societies which they share with their fellow citizens. Individuals in Western society may be trained to accept the status quo, which allows business leaders significant influence over the allocation of society’s assets, and thereby over societal developments. Formal education systems often encourage the maintenance of the (...) status quo, whereas they could encourage students to challenge it. This paper argues the need to help business students develop an understanding of critical theory, independent thought and self-improvement. The paper employs a case study approach which focuses on the development of one person, its author. He argues that those responsible for education today must encourage their students to think holistically about the consequences of business behaviour on society. If managers view business life through a scientific lens, focused primarily on the maximisation of financial returns, they will continue to encourage unsustainable behaviour, which damages the ecosystems and the social cohesion in society. Managers must learn to approach their business decisions as whole human beings. This will make it more likely they will manage in a sustainable way, and help them find meaning and happiness in their roles. (shrink)

This paper points to the lack of scientific images, including moving images, for promoting behavior analysis. Examples of what could be done to rectify this situation are contained in two teaching gambits that address practical and philosophical issues in the analysis of behavior. The first gambit is an elaboration of the shaping game that highlights issues associated with discriminative control and the role of private events in the analysis of behavior. The second gambit uses specially designed graphics, both 2-D and (...) 3-D, to show how an understanding of the behavioral stream underpins every aspect of the analysis of behavior. (shrink)

Heyman's target article is an analytical tour de force, but it makes too hard a distinction between voluntary and driven behavior. It is more fruitful to think about brain and behavior as shifting, interacting “agents,” represented by multiple neural circuits. This has the virtue of better connecting behavioral analysis with wet neuroscience.

I discuss various theoretical issues concerning maximizing, matching, and melioration. The model of addiction based on melioration has the key feature that a reduction in drag use increases both the value of drag-taking and the value of conventional activities. I found Heyman's target article stimulating. I don't feel competent to comment on drags but I do have some thoughts, both general and specific, on the theoretical issues.

Heyman's analysis of addiction suggests that drug taking is irrational. The irrationality of drug taking, however, may depend on the acceptance of mainstream society's view of what is valuable. Consideration of the addict's viewpoint and cultural aspects of drug taking may be useful in trying to fathom the “rationality” of drug taking.

I support the major theme of Heyman's target article that behavioral choice theory can enhance our understanding of drug dependence, but I raise concerns about the critique of the operant model of drug dependence, the underscoring of melioration to the exclusion of other theories of choice, and assertions about the unique effects of drug reinforcement.

The target article emphasizes the relationship between a matching law-based theory of addiction and the disease model of addiction. In contrast, this response emphasizes the relationship between the matching law theory and other behavioral approaches to addiction. The basic difference, I argue, is that the matching law specifies that choice is governed by local reinforcement rates. In contrast, economics says that overall reinforcement rate controls choice, and for other approaches there are other measures or no clear prediction at all. The (...) response also differs from the target article in that there is more emphasis on the finding that stimulus conditions determine whether choice is under local or overall reinforcement rate control.

Research findings on addiction are contradictory. According to biographical records and widely used diagnostic manuals, addicts use drugs compulsively, meaning that drug use is out of control and independent of its aversive consequences. This account is supported by studies that show significant heritabilities for alcoholism and other addictions and by laboratory experiments in which repeated administration of addictive drugs caused changes in neural substrates associated with reward. Epidemiological and experimental data, however, show that the consequences of drug consumption can significantly (...) modify drug intake in addicts. The disease model can account for the compulsive features of addiction, but not occasions in which price and punishment reduced drug consumption in addicts. Conversely, learning models of addiction can account for the influence of price and punishment, but not compulsive drug taking. The occasion for this target article is that recent developments in behavioral choice theory resolve the apparent contradictions in the addiction literature. The basic argument includes the following four statements: First, repeated consumption of an addictive drug decreases its future value and the future value of competing activities. Second, the frequency of an activity is a function of its relative (not absolute) value. This implies that an activity that reduces the values of competing behaviors can increase in frequency even if its own value also declines. Third, a recent experiment (Heyman & Tanz 1995) shows that the effective reinforcement contingencies are relative to a frame of reference, and this frame of reference can change so as to favor optimal or suboptimal choice. Fourth, if the frame of reference is local, reinforcement contingencies will favor excessive drug use, but if the frame of reference is global, the reinforcement contingencies will favor controlled drug use. The transition from a global to a local frame of reference explains relapse and other compulsive features of addiction. (shrink)

Connectionist models provide a promising alternative to the traditional computational approach that has for several decades dominated cognitive science and artificial intelligence, although the nature of connectionist models and their relation to symbol processing remains controversial. Connectionist models can be characterized by three general computational features: distinct layers of interconnected units, recursive rules for updating the strengths of the connections during learning, and “simple” homogeneous computing elements. Using just these three features one can construct surprisingly elegant and powerful models of (...) memory, perception, motor control, categorization, and reasoning. What makes the connectionist approach unique is not its variety of representational possibilities or its departure from explicit rule-based models, or even its preoccupation with the brain metaphor. Rather, it is that connectionist models can be used to explore systematically the complex interaction between learning and representation, as we try to demonstrate through the analysis of several large networks.

Understanding what motivates employees is essential to the success of organizational objectives. Therefore, properly capturing and explaining the full range of such motivations are important. However, the classical and most popular theories describing employee motives have neglected, if not omitted entirely, the importance of the ethical and spiritual dimensions of motivation. This has led to a model of a person as self-interested, amoral, and non-spiritual. In this paper, we attempt to expose this omission and offer a more complete taxonomy of (...) motivations which include these dimensions. Although more work will need to be done to fully develop the ethical and spiritual dimensions of motivation, the expanded taxonomy will provide the foundations and serve as a guide for such further research. Furthermore, this new categorization of motivations brings out the full dimensions of being human, which promises to lead to improved management practices with regard to employees and foster greater human flourishing in the workplace.

Four research strategies currently employed by mainstream psychologists in researching the experiences and behaviors of human subjects are criticized for diminishing the presence of subjectivity. Two perspectives that tend to exaggerate subjectivity are also criticized. A balanced approach to subjectivity is offered that: acknowledges a theoretical perspective that recognizes that there are invisible or nonsensorial characteristics of subjectivity that have to be theoretically appropriated, and that emphasizes the intersubjective dimension as being critical for properly assessing a balanced approach to human (...) subjectivity. A subject-dependent perspective that can efface its own interests is the attitude that is required for the achievement of objectivity. (shrink)

A common misunderstanding of the selected effects theory of function is that natural selection operating over an evolutionary time scale is the only functionbestowing process in the natural world. This construal of the selected effects theory conflicts with the existence and ubiquity of neurobiological functions that are evolutionary novel, such as structures underlying reading ability. This conflict has suggested to some that, while the selected effects theory may be relevant to some areas of evolutionary biology, its relevance to neuroscience is (...) marginal. This line of reasoning, however, neglects the fact that synapses, entire neurons, and potentially groups of neurons can undergo a type of selection analogous to natural selection operating over an evolutionary time scale. In the following, I argue that neural selection should be construed, by the selected effect theorist, as a distinct type of function-bestowing process in addition to natural selection. After explicating a generalized selected effects theory of function and distinguishing it from similar attempts to extend the selected effects theory, I do four things. First, I show how it allows one to identify neural selection as a distinct function-bestowing process, in contrast to other forms of neural structure formation such as neural construction. Second, I defend the view from one major criticism, and in so doing I clarify the content of the view. Third, I examine drug addiction to show the potential relevance of neural selection to neuroscientific and psychological research. Finally, I endorse a modest pluralism of function concepts within biology. (shrink)

Heyman's two crucial theses are that people over-value immediate rewards, and that addictive substances “subvert the value of competing commodities.” These perennial ideas were discussed by Plato. Whereas Heyman provides scientific clarification and support for the first, the second remains problematic. I outline how this deficiency might be remedied via evolutionary considerations.

Heyman's target article makes a strong case for a behavioral approach to addiction, yet some important assumptions require justification, and promising behavioral alternatives to the author's melioration approach should be considered. In particular, the behavioral economic approach to addiction appears well developed and comprehensive. How does the melioration approach complement or improve on a behavioral economic account?
