Prediction of Health Patterns from General Appraisal,Attributions, Coping,and Trait Anxiety

We examined the relationships among general appraisal style, attributional style, trait anxiety, coping styles, and health status (i.e., depression, hostility, and flu-like symptoms) in a study for which we also examined the validity of a trait measure of general appraisal. Participants completed personality measures at the beginning of an academic semester, and health assessments at regular intervals throughout the semester. Consistent with our predictions, after removing the influence of neuroticism and attributional style, general appraisal style led to more negative, and less positive affect 2 weeks later, and to more stressful and threatening appraisals of a life event occurring 3 months later. Multiple regression techniques showed that as predicted, after controlling for baseline health general appraisal style and attributional style predicted hostility and flu-like symptoms, and attributional style also predicted depression. These effects were mediated by trait anxiety. We discuss why both negative general appraisal and attributional styles may be risk factors for ill health.     

An investigation of everyday prospective memory

Prospective memory, remembering to carry out one’s planned activities, was investigated using a naturalistic paradigm. Three experiments, with a total of 405 participants, were conducted. The goal was to demonstrate that the cognitive processing underlying successful everyday prospective remembering involves components other than mere “memory.” Those components are probably best represented as individual differences in various cognitive capacities. More specifically, metamemory, attentional capacities, and planning processes that reprioritize intentions according to the demands of everyday life may determine how people actually accomplish the plans they establish for themselves. The results of these experiments suggest that researchers interested in the topic will have to contend with a multidimensional set of factors before any comprehensive understanding of prospective remembering can be realized.     

Fighting Igor: Exposing and Resisting the Irrational Side Using Cognitive-Behavioral Principles in Group Therapy

A visual cognitive behavioral framework developed, with indirect literature support, from the author's practice depicts a polarized conflict between a rational side and an irrational side, named Igor. Each side's characteristics, reasoning, and methods of dealing with thoughts, feelings, and behaviors in panic/phobic disorders are described. Techniques of a group therapy approach include members sharing symptoms, fears, and escape behaviors; the therapist providing corrective information and role playing of each side; and therapist/members monitoring and supporting behavioral homework. Outcome measures appear to support desired simplicity, palatability, efficiency, and effectiveness.     

Labeled Calculi and Finite-Valued Logics

A general class of labeled sequent calculi is investigated, and necessary and sufficient conditions are given for when such a calculus is sound and complete for a finite-valued logic if the labels are interpreted as sets of truth values (sets-as-signs). Furthermore, it is shown that any finite-valued logic can be given an axiomatization by such a labeled calculus using arbitrary "systems of signs," i.e., of sets of truth values, as labels. The number of labels needed is logarithmic in the number of truth values, and it is shown that this bound is tight.     

A Representation Theorem for a Decision Theory With Conditionals

This paper investigates the role of conditionals in hypothetical reasoning and rational decision making. Its main result is a proof of a representation theorem for preferences defined on sets of sentences (and, in particular, conditional sentences), where an agent’s preference for one sentence over another is understood to be a preference for receiving the news conveyed by the former. The theorem shows that a rational preference ordering of conditional sentences determines probability and desirability representations of the agent’s degrees of belief and desire that satisfy, in the case of non-conditional sentences, the axioms of Jeffrey’s decision theory and, in the case of conditional sentences, Adams’ expression for the probabilities of conditionals. Furthermore, the probability representation is shown to be unique and the desirability representation unique up to positive linear transformation. This revised version was published online in June 2006 with corrections to the Cover Date.     

Perceptions of Liver Transplant Candidates with or Without an Alcohol Use History

Cirrhosis secondary to alcohol use is a primary cause of liver disease and a medical condition for which liver transplantation is a viable treatment option. However, there remains considerable debate within both the lay and the medical communities regarding the distribution of a scarce medical resource to adults with alcoholism. This study examined college students' perceptions toward an adult, presented in a written vignette, for whom liver transplantation was medically indicated. The influence of gender (female and male) and alcohol use history (no alcohol history, alcoholism history with long-term abstinence, alcoholism history with current use) on these ratings was examined. Subjects rated the adult presented with no alcohol history more positively than they did the adults presented with a history of alcoholism. Also, the adult with no alcohol history was more likely to be offered transplantation and was given higher priority ratings for transplantation by subjects. While subjects' own alcohol use history and organ donor registration status were not associated with ratings, having a family member with an alcohol problem and personally knowing a transplant recipient were related to more favorable ratings toward the adult presented in the vignette. Implications of these findings as well as limitations of the study are discussed.     

Teaching the Introduction to Religions: Religious Pluralism in a Post-Colonial World

Taking seriously the implications of post-colonial theory, the authors revisit the introductory course (normally “World Religions”) as a course on the plurality of religions in contemporary U.S. culture. They explain the structure of the course, and discuss practical and ethical issues around student field visits to learn about other religions.     

Reexamining the goodness-of-fit problem for interval-scale scores

A classic data-analytic problem is the statistical evaluation of the distributional form of interval-scale scores. The investigator may need to know whether the scores originate from a single Gaussian distribution or from a mixture of Gaussian distributions or from a different probability distribution. The relative merits of extant goodness-of-fit metrics are discussed. Monte Carlo power analyses are provided for several of the more powerful goodness-of-fit metrics.
