The discounting model selector: Statistical software for delay discounting applications

Original, open‐source computer software was developed and validated against established delay discounting methods in the literature. The software executed approximate Bayesian model selection methods from user‐supplied temporal discounting data and computed the effective delay 50 (ED50) from the best performing model. Software was custom‐designed to enable behavior analysts to conveniently apply recent statistical methods to temporal discounting data with the aid of a graphical user interface (GUI). The results of independent validation of the approximate Bayesian model selection methods indicated that the program provided results identical to that of the original source paper and its methods. Monte Carlo simulation (n = 50,000) confirmed that true model was selected most often in each setting. Simulation code and data for this study were posted to an online repository for use by other researchers. The model selection approach was applied to three existing delay discounting data sets from the literature in addition to the data from the source paper. Comparisons of model selected ED50 were consistent with traditional indices of discounting. Conceptual issues related to the development and use of computer software by behavior analysts and the opportunities afforded by free and open‐sourced software are discussed and a review of possible expansions of this software are provided.     

Sigmund Freud and James Putnam: Friendship as a Form of Sublimation

This article focuses on Freud’s lectures at Clark University in 1909 and the correspondence that followed from Freud’s visit to America with the Boston neurologist James Jackson Putnam. Particular emphasis is given to the concept of sublimation, specifically to Putnam’s desire to make sublimation a goal of psychoanalysis and his view that sublimations should reflect the individual’s recognition of the interests of the community or desire for an ideal community. Against Putnam, we endorse Freud’s view that sublimation should not be a goal of psychoanalysis. However, we support Putnam’s emphasis on the social value of sublimations, but in a more limited sense than he proposes in his correspondence with Freud. We suggest that the correspondence between Putnam and Freud reflects the very fact that the lifting of sexual repressions makes possible the development of male friendships. Thus, we view the correspondence between Freud and Putnam as an instance of sublimation, and suggest that the friendship that this correspondence reflected and nurtured is an example of the ideal community to which we humans aspire but which often remains elusive and unrealized.     

The Lessons of Artistic Creativity for Pastoral Theologians

This article applies David W. Galenson’s (2006) typology of artistic creativity to pastoral theology. Galenson identifies two types of painters—conceptualists and experimentalists—and shows that their most important innovations occur at different stages of an artist’s career, that their methods are very different, and that each type produces predictable career frustrations which may, however, be counteracted. The fact that these types are found among sculptors, poets, novelists and film directors leads Galenson to propose that they are also found among scholars, thus inviting application of the findings of the study to pastoral theology as a discipline and to individuals who identify themselves as pastoral theologians. Galenson’s work is supplemented by Thomas Dormandy’s (2000) study of older painters.     

The Psychological Benefits of Bad Poetry

The author was the founder and secretary pro-tem of the Bad Poets Society at Princeton Theological Seminary. This distinction does not appear on his official resume. The Society did not have meetings but it had a newsletter that came out several times a year comprised of bad poetry written by members of the faculty and staff. These poetic works included reflections on institutional matters. This article contains bad poetry by the author relating to such matters. This poetry illustrates Sigmund Freud’s (Jokes and Their Relation to the Unconscious. Norton, New York, 1960) view of humor as saving in the expenditure of painful emotions, costly inhibitions, and difficult thinking. The parasitical nature of bad poetry is also noted and illustrated with the author’s own poems.     

Postulates for revising BDI structures

The process of rationally revising beliefs in the light of new information is a topic of great importance and long-standing interest in artificial intelligence. Moreover, significant progress has been made in understanding the philosophical, logical, and computational foundations of belief revision. However, very little research has been reported with respect to the revision of other mental states, most notably propositional attitudes such as desires and intentions. In this paper, we present a first attempt to formulate a general framework for understanding the revision of mental states. We develop an abstract belief-desire-intention model of agents, and introduce a notion of rationality for this model. We then present a series of formal postulates characterizing the processes of adding beliefs, desires, and intentions, updating costs and values, and removing beliefs, desires, and intentions. We also investigate the computational complexity of several problems involving the abstract model and comment on algorithms for revision.     

PROBABILIST ANTIREALISM

Until now, antirealists have offered sketches of a theory of truth, at best. In this paper, we present a probabilist account of antirealist truth in some formal detail, and we assess its ability to deal with the problems that are standardly taken to beset antirealism.     

An extended motor network generates beta and gamma oscillatory perturbations during development

This study examines the time course and neural generators of oscillatory beta and gamma motor responses in typically-developing children. Participants completed a unilateral flexion–extension task using each index finger as whole-head magnetoencephalography (MEG) data were acquired. These MEG data were imaged in the frequency-domain using spatial filtering and the resulting event-related synchronizations and desynchronizations (ERS/ERD) were subjected to voxel-wise statistical analyses to illuminate time–frequency specific activation patterns. Consistent with adult data, these children exhibited a pre-movement ERD that was strongest over the contralateral post-central gyrus, and a post-movement ERS response with the most prominent peak being in the contralateral precentral gyrus near premotor cortices. We also observed a high-frequency (∼80 Hz) ERS response that coincided with movement onset and was centered on the contralateral precentral gyrus, slightly superior and posterior to the beta ERS. In addition to pre- and post-central gyri activations, these children exhibited beta and gamma activity in supplementary motor areas (SMA) before and during movement, and beta activation in cerebellar cortices before and after movement. We believe the gamma synchronization may be an excellent candidate signal of basic cortical motor control, as the spatiotemporal dynamics indicate the primary motor cortex generates this response (and not the beta oscillations) which is closely yoked to the initial muscle activation. Lastly, these data suggest several additional neural regions including the SMA and cerebellum are involved in basic movements during development.     

Client Perceptions of Pretreatment Change

The authors suggest that when counselors have a rich understanding of pretreatment changes, they are better able to assist clients in capitalizing on such changes. The current study examined client perceptions of pretreatment changes. Thirty‐six clients completed Q‐sorts pertaining to pretreatment changes they experienced. Four factors pertaining to client perceptions of pretreatment change emerged from the study: problem legitimacy, spiritual resources, ambivalence, and hope. Clinical implications for working with the different pretreatment changes that emerged from this study are discussed.     

SCIENCE AND SERIOUS THEOLOGY: TWO PATHS FOR SCIENCE AND RELIGION'S FUTURE?

Although they take different approaches, both Taede A. Smedes and Kevin Sharpe have challenged the theology-and-science enterprise and raised important questions about theological and scientific assumptions behind this work. Smedes argues that theology should be taken more seriously, and Sharpe believes that theology should be more scientific. A proposed middle way involves engaging in the dialogue itself and exploring the questions and methodological implications that arise in the context of problem-focused interactions.
