BEHAVIOR ANALYSIS: THRIVING,BUT HOW ABOUT ITS FUTURE?

Behavior analysis has been thriving by continuing to make important theoretical and empirical contributions to a wide array of problems, as well as by contributing to interdisciplinary research. Applied research in behavior analysis is flourishing. Despite these positive signs there may be an erosion of support for basic research in animal learning and behavior, including behavior analysis. Increased attention by behavior analysts to fundamental problems in areas of cognition, including decision-making and language, may help behavior analysis to evolve more successfully. An experimental analysis of gambling may prove particularly fruitful.     

Response coding in the Simon task

Recent findings indicate that two distinct mechanisms can contribute to a Simon effect: a visuomotor information transmission on the one hand and a cognitive code interference on the other hand (see for e.g., Wiegand & Wascher, in Journal of Experimental Psychology: Human Perception and Performance 2005a). Furthermore, it was proposed that the occurrence of one or the other mechanism strongly depends on the way responses are coded. Visuomotor information transmission seems to depend on a correspondence between stimulus position and spatial anatomical status of the effector, whereas cognitive code interference is thought to be based on relative response location codes. To further test the spatial anatomic coding hypothesis, three experiments were conducted, in which the Simon effect with unimanual responses was investigated for horizontal (Experiment 1 and 2) and vertical (Experiment 3) stimulus-response (S-R) relations. Based on the finding of a decreasing effect function (indicating the presence of visuomotor information transmission) for horizontal and vertical S-R relations, it was concluded that visuomotor information transmission occurs whenever there is an overlap between the spatial stimulus feature and parameters of the motor representation of the response. Furthermore, the specific motor representation seems to be task dependent, that is, it entails those response parameters that clearly differentiate between the two response alternatives in a given task situation.     

SHARING THE WEALTH: FACTORS INFLUENCING RESOURCE ALLOCATION IN THE SHARING GAME

Students chose between two allocation options, one that gave the allocator more and another participant still more (the “optimal” choice) and one which gave the allocator less and the other participant still less (the “competitive” choice). In a within‐subjects design, students' behavior patterns were significantly correlated across the two rounds of decision‐making; however, students allocated more optimally when the allocation involved real rather than hypothetical money, suggesting that both motivational context and individuals' personality and/or experience influence preference patterns. The nature of the putative other participant did not affect the allocation: students allocated in a comparable fashion whether the other participant was said to be male, female, or a computer.     

Visual search in children and adults: top-down and bottom-up mechanisms

Three experiments investigated visual search for targets that differed from distractors in colour, size, or orientation. In one condition the target was defined by a conjunction of these features, while in the other condition the target was the odd one out. In all experiments, 6-7- and 9-10-year-old children were compared with young adults. Experiment 1 showed that children's search differed from adults' search in two ways. In conjunction searches children searched more slowly and took longer to reject trials when no target was present. In the odd-one-out experiments, 6-7-year-old children were slower to respond to size targets than to orientation targets, and slower for orientation targets than for colour targets. Both the other groups showed no difference in their rate of responding to colour and orientation. Experiments 2 and 3 highlighted that these results were not a function of either differential density across set sizes (Experiment 2) or discriminability of orientation and colour (Experiment 3). Across all three experiments, the results of both conjunction and odd-one-out searches highlighted a development in visual search from middle to late childhood.     

The Institute on Human Values in Medicine: Its Role and Influence in the Conception and Evolution of Bioethics

For ten years, 1971–1981, the Institute onHuman Values in Medicine (IHVM) played a keyrole in the development of Bioethics as afield. We have written this history andanalysis to bring to new generations ofBioethicists information about the developmentof their field within both the humanitiesdisciplines and the health professions. Thepioneers in medical humanities and ethics cametogether with medical professionals in thedecade of the 1960s. By the 1980s Bioethics wasa fully recognized discipline. We show the rolethat IHVM programs played in defining thefield, training faculty and helping schools todevelop programs. We review the beginnings ofthe IHVM in the crucible of social andtechnological change that led to theestablishment of the IHVM's parentorganization, the Society for Health and HumanValues. We then turn to the IHVM programsthrough which Faculty members receivedfellowships to explore new crossovers betweenthe humanities and the health professions. Wehave not only described the Fellows Program asit existed in 1973–1980, but have completed asurvey of the fellows a quarter of a centuryafter they held their fellowships. We describeother IHVM programs designed to facilitate theinitiation and development of new humanitiesprograms, to explore conceptual issues betweenmedicine and five humanities fields, to conductissue driven or educational method conferencesand to advance humanities programs intograduate education through the Directors ofMedical Education.     

GLOBAL JUSTICE AFTER THE FALL Christian Realism and the "Law of Peoples"

In The Law of Peoples John Rawls casts his proposals as an argument against what he calls “political realism.” Here, I contend that a certain version of “Christian political realism” survives Rawls's polemic against political realism sans phrase and that Rawls overstates his case against political realism writ large. Specifically, I argue that Rawls's dismissal of “empirical political realism” is underdetermined by the evidence he marshals in support of the dismissal and that his rejection of “normative political realism” is in tension with his own normative concessions to political reality as expressed in The Law of Peoples. That is, I contend that Rawls, himself, needs some form of political realism to render persuasive the full range of normative claims constituting the argument of that work.     

The Form of Reason: Participation in the Work of Richard Hooker,Benjamin Whichcote,Ralph Cudworth and Jeremy Taylor

The article traces the centrality of the patristic doctrine of theosis in the work of four significant figures in seventeenth century Anglican theology. Particular attention is paid to their understanding of reason as a participation in the incarnate Logos. Attention is drawn to their pedagogical method, which sees theology as ‘rather a divine life than a divine knowledge’ (Taylor), and to their reticence in defining too precisely the content of doctrine. Finally the Anglican via media is seen not as a political compromise, but as one way of fruitfully expressing the mediating grace between Creator and creation.     

Integration of Certainty,Severity, and Celerity Information in Judged Deterrence Value: urther Evidence and Methodological Equivalence1

The purposes of these studies were (a) to establish on a general basis whether 3 time-honored manipulable components of punishment combine additively, or multi-plicatively in determining the judged deterrence value of a sanction, and (b) to explore the equivalence in principle of two mutually exclusive experimental designs. Study 1 used a repeated measures design whereas main and interactive effects of certainty and severity were substantial and appeared to follow a multiplying rule, celerity effects were very small and local. Studies 2a and 3 used independent groups and established that the results of Study 1 were not merely an arbitrary product of the method. The discussion addresses the minimal effects of celerity, the interaction between certainty and severity, and the theoretical implications of choice of method.     

An empirical test of the problem solving model of depression and its application to the prediction of anxiety and anger

Building on research which has found positive but small correlations between stressful life events and negative psychological outcomes as well as studies which have demonstrated support for the problem solving model of depression, this study replicated the Problem Solving Model of Depression using instruments not previously used in this area. Additionally, this study tested the application and extension of the problem solving model to other emotions by assessing the efficacy of three variables, Negative Life Events, Current Problem, and Problem Solving as predictors of Depression, Anxiety, and Anger. To test this model, five assessment instruments were administered to 110 male and 178 female graduate students. Support was found for the application of this model to the prediction of Depression. While Current Problem and Problem Solving were related to Anxiety, Negative Life Events were not. In predicting Anger, some limited support was found for this model with females but no support was found with males.
