Trends in presentations at the annual conference of the association for behavior analysis

The present report analyzes trends in attendance and presentations at the annual conference of the Association for Behavior Analysis (ABA). Numbers of registered attendees were plotted over time. The trends show that the number of registered attendees has grown considerably over the last three decades, with the largest proportion of the growth occurring during the last 10 years. This growth is shown to be correlated with the introduction of board certification in behavior analysis (BCBA and BCABA). In addition, conference programs from 1980 through 2007 were coded, and all presentations were categorized into one of four areas (application, basic research, conceptual, and verbal behavior) based on the primary designator codes chosen by the authors at the time of submission. An analysis of the total number of presentations in each category indicates that applied research presentations have always outnumbered the other three categories. The absolute number of presentations related to application has grown faster than presentations in other categories. However, correcting for population growth shows that the relative proportion of presentations in the four areas has remained fairly constant over the last 28 years.     

Working memory, metacognitive uncertainty, and belief bias in syllogistic reasoning

Studies of syllogistic reasoning have shown that the size of the belief bias effect varies with manipulations of logical validity and problem form. This paper presents a mental models-based account, which explains these findings in terms of variations in the working-memory demands of different problem types. We propose that belief bias may reflect the use of a heuristic that is applied when a threshold of uncertainty in one's processing-attributable to working-memory overload-is exceeded during reasoning. Three experiments are reported, which tested predictions deriving from this account. In Experiment 1, conclusions of neutral believability were presented for evaluation, and a predicted dissociation was observed in confidence ratings for responses to valid and invalid arguments, with participants being more confident in the former. In Experiment 2, an attempt to manipulate working-memory loads indirectly by varying syllogistic figure failed to produce predicted effects upon the size of the belief bias effect. It is argued that the employment of a conclusion evaluation methodology minimized the effect of the figural manipulation in this experiment. In Experiment 3, participants' articulatory and spatial recall capacities were calibrated as a direct test of working-memory involvement in belief bias. Predicted differences in the pattern of belief bias observed between highand lowspatial recall groups supported the view that limited working memory plays a key role in belief bias.     

Relations and Dissociations between Appraisal and Emotion Ratings of Reasonable and Unreasonable Anger and Guilt

Recent studies have used self-report methods to defend a close associative or causal connection between appraisal and emotion. The present experiments used similar procedures to investigate remembered experiences of reasonable and unreasonable anger and guilt, and of nonemotional other-blame and selfblame. Results suggest that the patterns of appraisal reported for reasonable examples of emotions and for situations where there is a near absence of emotion may be highly similar, but that both may differ significantly from the appraisal profiles reported for unreasonable examples of the same emotions. Further, relevant appraisals were not always identified by participants as the most influential determinants of guilt and anger. These findings demonstrate either that the relationship between certain appraisals and emotions is less consistent than implied in some contemporary versions of appraisal theory, or that there are problems with the validity of existing questionnaire-based measures of the variables in question.     

On Robert Jenson's Trinitarian Thought

This paper addresses Robert Jenson's critique of impassibility along with his Trinitarian formulations. Jenson's decision to eschew a doctrine of divine impassibility leads him to adopt a Kantian conception of subjectivity in order to explicate the traditional concept of hypostasis. In turn, Jenson advocates a Hegelian notion of determinate negation to relate to a concept of being dependent upon a German Idealist figuration of temporality. The final section of the paper contrasts Jenson's modernist immanentism with the positive perichoretic movement of Jonathan Edwards' trinitarian thought. For Edwards, the Trinity cannot be known as a repeatable object of knowledge reflected within human consciousness, but as a non-identical repletion of eternal love to which univocal categories do not apply.
