What distinguishes a whole from an arbitrary sum of elements? I suggest a temporal and causal oriented approach. I defend two connected claims. The former is that existence is, by every means, coextensive with being the cause of a causal process. The latter is that a whole is the cause of a causal process with a joint effect. Thus, a whole is something that takes place in time. The approach endorses an unambiguous version of Restricted Composition that suits most commonsensical (...) intuitions about wholes. (shrink)

First, a number of previous theories of intrinsic motivation are reviewed. Then, several studies of highly motivating computer games are described. These studies focus on what makes the games fun, not on what makes them educational. Finally, with this background, a rudimentary theory of intrinsically motivating instruction is developed, based on three categories: challenge, fantasy, and curiosity.Challenge is hypothesized to depend on goals with uncertain outcomes. Several ways of making outcomes uncertain are discussed, including variable difficulty level, multiple level goals, (...) hidden information, and randomness. Fantasy is claimed to have both cognitive and emotional advantages in designing instructional environments. A distinction is made between extrinsic fantasies that depend only weakly on the skill used in a game, and intrinsic fantasies that are intimately related to the use of the skill. Curiosity is separated into sensory and cognitive components, and it is suggested that cognitive curiosity can be aroused by making learners believe their knowledge structures are incomplete, inconsistent, or unparsimonious.

Heyman makes a convincing case that a melioration choice strategy is sufficient to produce addictive behavior. But given a plethora of addiction theories, the question is whether melioration theory is superior to rivals more sophisticated than a simple disease model or operant conditioning account. Heyman offers little direct evidence that melioration actually causes the addictions we observe.

The way people come to report private stimulation arising within their own bodies is not well understood. Although the Darwinian assumption of biological continuity has been the basis of extensive animal modeling for many human biological and behavioral phenomena, few have attempted to model human communication based on private stimulation. This target article discusses such an animal model using concepts and methods derived from the study of discriminative stimulus effects of drugs and recent research on interanimal communication. We discuss how (...) humans acquire the capacity to identify and report private stimulation and we analyze intra- and interspecies differences in neurochemical mechanisms for transducing interoceptive stimuli, enzymatic and other metabolic factors, learning ability, and discrimination learning histories and their relation to psychiatric and developmental disabilities.

To avoid teleological interpretations, it is important to make a distinction between functions and uses of consciousness, and to address questions concerning the consequences of consciousness. Assumptions about the phylogenetic distribution of consciousness are examined. It is concluded that there is some value in identifying consciousness an exclusively human attribute.

Choosing the smaller, less delayed reinforcers of drug abuse (including cessation of withdrawal) over the larger, more delayed reinforcers of a healthy life can be described as impulsiveness (the opposite of self-control). Examination of drug abuse using a self-control/impulsiveness framework can help explain many of the puzzles about this behavior, while tying drug abuse into a large research database.

Gray's integration of the different levels of description and explanation in his theory is problematic: The introduction of consciousness into his theorising consists of the mind-brain identity assumption, which tells us nothing new. There need not be correlations between levels of description. Gray's account does not extend beyond “brute” correlation. Integration must be achieved in a principled, mutually constraining way.

The military is a major driver of technological, world-changing innovations which, like the Internet, often have unpredictable dual uses and widespread civilian impact (?blowback?). Ethical and policy concerns arising from such technologies, therefore, are not limited to military affairs, but can have great implications for society at large as well. This paper will focus on two technology areas making headlines at present: human enhancement technologies and robotics, representing both biological and technological upgrades to the military. The concerns we will raise (...) are about (1) the unintended effects that these technologies could have on society and (2) the possibly self-defeating nature of these military programs in making war itself more, rather than less likely to occur. Given that society also can influence military programs (e.g., through civil protests) it is important for the military to attend to such concerns. (shrink)

Economic models of addiction are choice-based. These models push the choice paradigm too far by modeling addiction as rational, normative behavior. Heyman's target article provides a sensible alternative to this economic approach by emphasizing that addiction is characterized by ambivalence and a perceived loss of self control. However, matching may not be a satisfactory platform on which to build this alternative model. Matching experiments do not provide evidence of ambivalence or perceived loss of self control.

This experimental study evaluated the influence of stated organizational concern for ethical conduct upon managerial behavior. Using an in-basket to house the manipulation, a sample of 113 MBA students with some managerial experience reacted to scenarios suggesting illegal conduct and others suggesting only unethical behavior. Stated organizational concern for ethical conduct was varied from none (control group) to several other situations which included a high treatment consisting of a Code of Ethics, an endorsement letter by the CEO and specific sanctions (...) for managerial misconduct. Only in the case of suggested illegal behavior tempered by high organizational concern were managers influenced by organizational policy to modify the morality of their actions. However, the responses to the illegal scenarios were significantly more ethical than the reactions given to the unethical (but not illegal) situations. The implications of these findings are then discussed. (shrink)

Teleological behaviorism, unlike Skinnerian behaviorism, recognizes that are needed to account adequately for human behavior, but it rejects the essential role in behavioral explanations of the subjective perspective of the agent. I argue that teleological behaviorism fails because of this rejection.
