There may be evolutionary as well as economic reasons why organisms generally act impulsively. I discuss this possibility and suggest some follow-up experiments that may clarify the exciting empirical and theoretical contributions made by the experiments discussed in the target article.

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?

The commentary argues that we cannot be sure that human consciousness has survival value and that in order to understand the origins and, perhaps, the function of consciousness, we should examine the behavioural and neural precursors to consciousness in nonhumans. An example is given of research on the role of context in decisions regarding fleeing from probable predators in the Mongolian gerbil.

Rachlin's hyperbolic-discounting model captures basic features of the subtlety of human impulsiveness and self-control and has received convincing experimental support. His distinction between self-control patterns and impulsive acts expands his earlier work to a greater range of self-control behaviors. Possible mechanisms that may weaken or strengthen patterns of self-control are considered.

Gray's account is remarkable in its depth and scope but too little attention is paid to poor correspondences with the literature on hippocampal/subicular damage, the theta rhythm, and novelty detection. An alternative account, focusing on hippocampal involvement in organizing memories in a way that makes them accessible to conscious recollection but not in access to consciousness per se, avoids each of these limitations.

For many of our contemporaries, there is no more pressing issue than the acute ecological challenges facing the planet. Environmental degradation has reached a tipping point, but how have we fallen into such a predicament? At a deeper level, this critical situation can be seen as a mirror that reflects the spiritual crisis gripping the soul of humanity today. This commenced with the secularizing impetus of the Enlightenment project, which has led to a diminished understanding of the human psyche and (...) the cosmos itself. The anomaly of modern Western psychology is that it stems from the same desacralized and reductionistic outlook. By contrast, a deep-seated connection between sentient beings, the environment, and the Spirit has been recognized in all other times and places, throughout humanity’s traditional civilizations. By a resurrection of a “science of the soul” via a rehabilitated sacred cosmology, the spiritual roots of the ecological crisis can be restored and seen in a proper light. This essay examines the metaphysical dimension of the environmental crisis. The framework employed for this study is the “transpersonal” perspective of the perennial psychology—an application of the insights found in the world’s great wisdom traditions. The objective of the study is to propose a more holistic approach to understanding the essential relationship between our humanity and the natural environment—in all of its boundless and complex variety—seen as a manifestation of divine reality.

The purpose of this commentary is to discuss briefly a few points arising from Malone's (2001) interesting paper, "Ontology Recapitulates Philology: Willard Quine, Pragmatism, and Radical Behaviorism." Malone's paper serves both as a tribute to Quine as well as a reexamination of the possible pathways of influence between Quine and B. F. Skinner. These remarks are directed primarily to questions involving pragmatism in Skinner's radical behaviorism. Some of the points made here have been discussed in more detail elsewhere (Leigland, 1999).

With S.S. Stevens, operationism became an important influence in psychology. In this paper I discuss the differences between Bridgman's and Stevens' proposals on operationism and the role that operational definitions play in scientific theory. I discuss how Stevens' notions of the basic act of discrimination and of the relation procedure–outcome influenced B.F. Skinner's criteria under which the main conceptual distinctions in operant psychology were formulated. The operational origin of the dichotomies between respondent and operant behavior, contingency-shaped and rulegoverned behavior, private (...) and public events, and verbal and nonverbal behavior are examined.

For radical behaviorists, talk about "private events" could be about any of four things: (a) private behavioral events, (b) physiology, (c) dispositions, or (d) explanatory fictions. Talk about private events as behavioral engages the influence of feelings, sensations, and covert opérant behavior. Analyses based on private behavioral events allow radical behaviorists to understand how those events contribute to contingencies controlling subsequent operant behavior, whether verbal or nonverbal. Talk about private events in physiological terms risks confounding explanatory categories. Although physiology necessarily (...) participates in behavioral events, physiological events are not the same type as behavioral events, public or private. Rather, an organism's physiology is a material cause. To portray physiology as an autonomous, initiating cause, as traditional psychology often does, creates a variety of explanatory problems. Talk about private events as dispositions does not reflect anything literally private. Rather, dispositional talk reflects the probability of behavior engendered by contingencies. Dispositional talk is about effects, instead of causes or intervening variables as traditional psychology often portrays them. Finally, some talk ostensibly about private events is little more than an appeal to explanatory fictions. This talk, common in traditional psychology, owes its strength to the everyday social reinforcement inherent in "folk psychology." The talk represents a surrender to mentalism and methodological behaviorism, notwithstanding any claims that it is "theoretical.". (shrink)

Although culturally prominent modernist influences account for much of Skinner's early behaviorism, the subsequent changes in his views are appropriately considered as postmodern and are indebted to other sources. These changes are strikingly apparent in his 1945 publication. "The Operational Analysis of Psychological Terms." In that publication. Skinner introduced a probabilistic three-term contingency for verbal behavior with an expanded contextualism and an increased emphasis on consequence with a clear alignment to pragmatism. Instead of reaffirming the mechanistic and necessitarian values of (...) modernism that he had previously embraced, Skinner was aligning himself with the postmodern values of pragmatism and selectionism.

The present article attempts to investigate the 'philosophical foundations' of psychology and thereby of the social sciences in general with regard to a central problem, viz. the question of the 'inner'. It does this with special critical reference to an authoritative psychological theory, viz. the so-called 'mediation theory', and tries to show the necessity of interdisciplinary clarification. In the first part mediation theory was introduced as a variant of psychological behaviorism which attempts to substitute for the untenable total neglect of (...) 'inner' events a way of talking about them which is secured methodologically and retains a behavioral foundation. Of the three crucial questions raised by the project the second, viz. question, which concerns the theoretical status of the assumed inner mediators could be answered to the effect that they must be "hypothetical constructs" having the nature of real, phenomenally verifiable events, if, indeed, they are to figure as links in S-R-chains. Conceiving of them as "intervening variables", such a conception would exclude this function. The discussion of 'internalization' of behavior sequences as assumed by mediation theory has led to the conclusion that the relevant phenomena cannot, in this case, justify the necessity of a non-dispositional explanation which goes beyond 'external' performances ). Likewise the subject matter of question remained undecided; that is, the possibilities of phenomenally verifying the assumed 'inner' mediation processes which are only asserted to exist by the theory but are unspecified in content. Therefore, the observable performances in the case of sequential behaviour do not support the mediation theoretic solution of the problem of the 'inner'. (shrink)
