Ear-catching? Real-world distractibility scores predict susceptibility to auditory attentional capture

Although many of the everyday distractions that we encounter are auditory, most research on distractor processing to date has focused on the visual domain. A common measure of everyday distractibility is the Cognitive Failures Questionnaire (CFQ; Broadbent, Cooper, FitzGerald, & Parkes British Journal of Clinical Psychology 21: 1–16, 1982), which has previously been successfully linked with performance on controlled visual-attention tasks (e.g., Forster & Lavie Psychological Science 18: 377–381, 2007; Kanai, Dong, Bahrami, & Rees Journal of Neuroscience 31: 6620–6626, 2011; Tipper & Baylis Personality and Individual Differences 8: 667–675, 1987), such that high scorers tend to display greater distractor interference than do low scorers. We examined whether the same relationship would hold in hearing. Participants performed an auditory attentional-capture task, by responding to a target sound while ignoring an irrelevant singleton distractor (presented on half of the trials). We found that CFQ score successfully predicted distractor interference, since participants who reported being more distractible in everyday life produced more errors in the presence of the irrelevant singleton than did low scorers on the CFQ. This finding is the first to demonstrate a relationship between auditory distractor interference and everyday distractibility, and it confirms that performance on this type of laboratory-based attentional-capture task can successfully be related to behavior outside the laboratory.     

Self-Regulation and Other Executive Functions Relationship to Pediatric OCD Severity and Treatment Outcome

The intersection of obsessive-compulsive disorder (OCD) and executive functioning (EF) in children and adolescents is an emerging topic in the current literature. Spurred by the consistent association between increased EF deficits and higher adult obsessive-compulsive severity, a few initial studies have replicated this relationship in pediatric OCD samples and also have found preliminary evidence that EF deficits are associated with worse response to first-line psychotherapeutic or psychopharmacological treatments for pediatric OCD. This study aimed to extend the literature by providing the first comprehensive investigation of how multiple EF domains, measured repeatedly over the course of treatment, impact pediatric obsessive-compulsive severity and response to multimodal treatment. Multi-level modeling results found that deficits in shifting, inhibition, emotional control, planning/organizing, monitoring and initiating all predicted higher average obsessive compulsive severity across treatment. Interestingly, out of the eight domains of EF investigated, only emotional control moderated treatment outcome such that those with worse emotional control experienced less of a reduction in obsessive-compulsive severity during treatment. The findings generally align with previous theories for the link between EF and OCD and indicate that emotional control has important implications in the treatment of pediatric OCD. In fact, emotional control may provide one explanation for why factors such as disgust sensitivity, oppositional behavior, and third-wave behavioral treatment techniques have all been linked to pediatric OCD treatment outcome. Future research should investigate augmentation strategies that target emotional control in children and adolescents.     

Human latent inhibition: Problems with the stimulus exposure effect

Latent inhibition (LI) is a startlingly simple effect in which preexposure of a stimulus without consequence retards subsequent responding to a stimulus–consequence relation. The effect was first demonstrated with Pavlovian conditioning in animals and was later suggested to be a marker of human psychopathology such as schizophrenia. Individual differences in LI has supported the continued use of animal models to understand human mental health. In this review, we ask whether there is sufficient evidence to support the continued application of LI from animal models to human psychopathology because of the weak evidence for LI in humans. There is considerable variability in the methods used to assess LI, sustaining different theoretical accounts of the effects observed, which differ from the accepted accounts of LI as demonstrated in animals. The review shows that although there have been many experiments testing human LI, none provide the necessary experimental controls to support the conclusion that retarded responding is caused simply by preexposure to a stimulus, as has been demonstrated with animal models. Establishing this conflict, we set out a framework for future research.     

Mathematics in Economics: An Austrian Methodological Critique

Even the briefest and most superficial perusal of leading mainstream economics journals will attest to the degree that mathematical formalism has captured the economics profession. Whereas up to the early 20th century virtually all of the output of the dismal scientists was in the literary format, by the early 21st century this is not at all any longer the case. Mathematical formalism is supposed to serve economics, and yet now true economic insight has been crowded out by the math. If mainstream neoclassical economics is to come back to its proper path, a far less central role for mathematical economics, statistics and econometrics will have to be fashioned.     

ROBERT JOHN RUSSELL VERSUS THE NEW ATHEISTS

This essay compares Robert John Russell's work in his recent book Cosmology from Alpha to Omega: The Creative Mutual Interaction of Theology and Science (2008) to that of the authors known collectively as "the new atheists." I treat the latter as recent contributors to the modern tradition of scientific naturalism. This tradition makes claims to legitimacy on the basis of its close relations to the natural sciences. The purpose of this essay is to show up the poverty of the naturalist tradition's scientific credentials by contrasting it with Russell's careful account of positive relations between science and Christian theology.     

Creativity and Ethics: The Relationship of Creative and Ethical Problem-Solving

Students of creativity have long been interested in the relationship between creativity and deviant behaviors such as criminality, mental disease, and unethical behavior. In the present study we wished to examine the relationship between creative thinking skills and ethical decision-making among scientists. Accordingly, 258 doctoral students in the health, biological, and social sciences were asked to complete a measure of creative processing skills (e.g., problem definition, conceptual combination, idea generation) and a measure of ethical decision-making examining four domains, data management, study conduct, professional practices, and business practices. It was found that ethical decision-making in all four of these areas was related to creative problem-solving processes with late cycle processes (e.g., idea generation and solution monitoring) proving particularly important. The implications of these findings for understanding the relationship between creative and deviant thought are discussed.
