On the alleged connection between moral evil and human freedom

Those who advance the traditional argument from human freedom presume that human freedom provides an adequate explanation of moral evil. I argue that this presumption is erroneous. An adequate explanation of our capacity to make choices that produce moral evil must be distinguished from an adequate explanation of the actuality of such choices. Human freedom may account for our ability to make choices that issue in moral evil. It cannot, by itself, account for our actually making such choices. Something more than our potential for choices that produce moral evil is required to adequately explain the profusion of moral evil that we actually find in the world.     

Effects of depression on expectancy in sustained attention

The effects of expectancies generated during a pretest on the subsequent vigilance performance of depressed and nondepressed observers were assessed. Among the nondepressed, those who were exposed to a high signal probability during the pretest detected more signals in the main watch than those exposed to a low pretest probability, regardless of the signal probability in the vigil itself (high or low). This expectancy effect was not evident among the depressed. The vigilance decrement in both subject categories was steeper under conditions of low as compared to high test probability. These results indicate that depressed monitors do not demonstrate a deficit in attentional capacity. It is suggested that the nonperseveration of pretest expectancies among the depressed may stem from a lack of motivation to effortfully process information in the same manner as nondepressed observers.The authors would like to thank Mark Scerbo and Tom Lanzetta for their technical assistance.     

TRAINING SUPERVISORS IN A COLLABORATIVE TEAM APPROACH TO PROMOTE PEER INTERACTION OF CHILDREN WITH DISABILITIES IN INTEGRATED PRESCHOOLS

Three supervisors of integrated preschools were trained in a collaborative team approach to encourage resource and classroom teachers to develop strategies that promote peer interaction of all children, including children with disabilities. The focus of classroom teachers' behaviors and the interactive play of children with disabilities were measured daily in both a training (indoor play period) and a generalization (outdoor play period) setting. In a multiple baseline design, supervisors were individually trained in a collaborative team approach using a manual, modeling, and role playing; then they implemented the approach with classroom and resource teachers. We found that after supervisor training, classroom teachers increased their behaviors directed towards children with disabilities and decreased their behaviors directed towards nondisabled children. Moreover, we found a doubling of the interactive play of children with disabilities and, for two of the three classes, an increase in the interactive play of comparison children, randomly selected by the classroom teachers. Changes in both teachers' and children's behaviors were also found in the generalization setting. The implications of the results for interventions in community settings are discussed.     

Political and interpersonal aspects of ethics consultation

Previous papers on ethics consultation in medicine have taken a positivistic approach and lack critical scrutiny of the psychosocial, political, and moral contexts in which consultations occur. This paper discusses some of the contextual factors that require more careful research. We need to know more about what prompts and inhibits consultation, especially what factors effectively prevent house officers and nonphysicians from requesting consultation despite perceived moral conflict in cases. The attitudes and institutional power of attending medical staff seem important, especially where innovative interventions raise ethical questions. Ethics consultants also need to address the thorny problems of the origin(s) of the consultant's authority, whistleblowing, conflicts of interest that affect the consultant, persistently poor communications in hospitals, systemic inequity in the availability or quality of services for some, and the standing of the consultant's recommendations, including their appearance in the patient's medical record.     

Induction,focused sampling and the law of small numbers

Hilary Kornblith (1993) has recently offered a reliabilist defense of the use of the Law of Small Numbers in inductive inference. In this paper I argue that Kornblith's defense of this inferential rule fails for a number of reasons. First, I argue that the sort of inferences that Kornblith seeks to justify are not really inductive inferences based on small samples. Instead, they are knowledge-based deductive inferences. Second, I address Kornblith's attempt to find support in the work of Dorrit Billman and I try to show that close attention to the workings of her computational model reveals that it does not support Kornblith's argument. While the knowledge required to ground the inferences in question is perhaps inductively derived, Billman's work does not support the notion that small samples provide a reliable basis for our generalizing inferences.     

NONCONTINGENT ESCAPE AS TREATMENT FOR SELF-INJURIOUS BEHAVIOR MAINTAINED BY NEGATIVE REINFORCEMENT

We extended research on the role of noncontingent positive reinforcement following a functional analysis of attention-maintained self-injurious behavior to self-injury maintained by negative reinforcement in 2 young males with developmental disabilities. During a pretreatment functional analysis, each participant's self-injury was shown to be differentially sensitive to escape from instructional activities as negative reinforcement. During noncontingent escape, escape from learning activities was provided on a fixed-time schedule that was not influenced by the participant's behavior. One participant was also exposed to differential negative reinforcement of other behavior. During this condition, escape from instructional activities was provided contingent on the omission of self-injury for prespecified intervals. Results showed that the provision of escape, even when noncontingent, resulted in significant reductions in self-injury. These results are particularly interesting in light of the experimental history of noncontingent reinforcement as a control rather than as a therapeutic procedure. Noncontingent escape is discussed as a form of extinction that may be less likely than other forms of extinction to produce severe side effects.     

NEGATIVE SIDE EFFECTS OF NONCONTINGENT REINFORCEMENT

Noncontingent reinforcement (NCR) has emerged as a treatment package for severe behavior problems. Although concerns about potential side effects (such as incidental reinforcement) have been raised, there have been few reported negative side effects in published studies to date. In this article, we report an NCR treatment evaluation for severe aggression that produced (a) an extinction burst and (b) incidental reinforcement. These side effects were evaluated by examining within-session response patterns and response distributions. As a solution, a brief omission contingency was added to the reinforcement schedule. The omission contingency resulted in decreased aggression rates.
