IS THERE A DECISIVE TEST BETWEEN MATCHING AND MAXIMIZING?

Reinforcers under typical concurrent variable-interval, variable-ratio schedules may be (a) earned and obtained during the variable-interval component, (b) earned and obtained during the variable-ratio component, or (c) earned during the variable-ratio component and obtained during the variable-interval component. Categories a and b, which have no bearing on matching versus maximizing accounts of choice, were set at zero. The rate of Category c reinforcers and the duration of a changeover delay were varied. Simple matching, which predicts exclusive choice of the variable-interval component, and strict maximizing of overall reinforcement rate, which predicts a bias towards the variable-ratio component, were both disconfirmed: Subjects spent approximately 25% of their time in the variable-ratio component, contrary to the matching prediction, but earned only about one third of the reinforcers predicted by strict maximizing. However, maximizing describes the findings functionally in terms of discounting of delayed reinforcers; matching may describe the data in terms of a restructuring of the alternatives. Matching and maximizing are not competing theories about the fundamental nature of choice, but compatible points of view that may reveal environmental function and behavioral structure.     

Therapeutic factors in two forms of inpatient group psychotherapy: Music therapy and verbal therapy

Therapeutic processes in one type of creative arts group psychotherapy, music therapy, were compared with verbal group psychotherapy. Sixty-one short-term inpatients ranked group psychotherapy curative factors and completed satisfaction ratings. Therapists rated 201 group therapy sessions— 109 music therapy and 92 verbal therapy. Statistical analysis revealed that patients highly valued both group formats. The mean curative factor rankings for both groups included cohesiveness, instillation of hope, and altruism among the most helpful factors. Therapists' ratings indicated qualitative differences between the two groups. Music therapy involved more therapeutic interaction among patients and emotional expression, whereas verbal therapy emphasized concrete problem solving.Supported in part by Biomedical Research Support Grant Program grant #S07-RR05755 from the Division of Research Resources, National Institutes of Health.     

A TALE OF TWO CONTROVERSIES: COMMENT

Abstract. The educational controversies that Martin Eger discusses regarding moral education and the teaching of "creationism" arise from taking a single aspect of moral education and making it the whole, and from taking a single aspect of scientific work and assuming that it is the whole. The distinction between teaching science as application and teaching it as education is crucial in confronting these problems.     

A comparison of UFO and near-death experiences as vehicles for the evolution of human consciousness

This study compares unidentified flying object experiencers (UFOErs) with near-death experiencers (NDErs) in regard to changes in attitudes toward self, others, and life in general, toward religious or spiritual orientation, and toward psychic abilities and beliefs. Kenneth Ring's questionnaires administered to NDErs (1984) were given in this study to 93 persons whose UFOE included either a light experience, an object experience, or a close encounter. The author concludes that the UFOE, like the NDE, provides impetus toward spiritual growth, but neither as consistently nor as strongly.This paper was derived in part from her M.A. thesis submitted to John F. Kennedy University.     

The devil in heaven: A near-death experience with both positive and negative facets

Although the considerable majority of reported near-death experiences (NDEs) are associated with positive affect, there are occasional cases of so-called negative NDEs that are dominated by fear and anguish. The phenomenological status of the negative experiences and their relationship to the more typical positive NDEs have been the subject of increasing speculation. In that light, the NDE described in this paper is of interest because it began to unfold as a positive experience but then changed course to become a negatively toned one. We present the details of this case and note its principal theoretical implications.     

Consumption-leisure tradeoffs in pigeons: Effects of changing marginal wage rates by varying amount of reinforcement

Pigeons' rates of responding and food reinforcement under simple random-ratio schedules were compared with those obtained under comparable ratio schedules in which free food deliveries were added, but the duration of each food delivery was halved. These ratio-with-free-food schedules were constructed so that, were the pigeon to maintain the same rate of responding as it had under the simple ratio schedule, total food obtained (earned plus free) would remain unchanged. However, any reduction in responding would reduce total food consumption below that under the simple ratio schedule. These “compensated wage decreases” led to decreases in responding and decreases in food consumption, as predicted by an economic model of labor supply. Moreover, the reductions in responding increased as the ratio value increased (i.e., as wage rates decreased). Pigeons, therefore, substituted leisure for consumption. The relationship between these procedures and negative-income-tax programs is noted.
