Musical Preferences as a Function of Stimulus Complexity of Piano Jazz

Seven excerpts of modern jazz piano improvisations were selected to represent a range of perceived complexities. Audio recordings of the excerpts were played for 27 listeners who were asked to indicate their level of enjoyment on 7-point scales. Indications of enjoyment followed an inverted-U when plotted against perceived complexity of the music. Overall enjoyment was less for nonmusician listeners than for musician listeners. The inverted-U function was similar to the relations predicted by Wundt, over 100 years ago, and obtained by other investigators for responses to classical piano music and nonvocal New Age music. Assuming that perceived complexity generates comparable arousal levels, these findings substantiate optimal level of stimulation theory.     

Cleaning Up the Dirty Work: Professionalization and the Management of Stigma in the Cosmetic Surgery and Tattoo Industries

This article considers the similarities between the cosmetic surgery and tattoo industries, focusing on how each has transitioned from a disreputable and deviant industry to achieve varying degrees of mainstream acceptance and success. Specifically, each industry is conceptualized as engaging in “dirty work” requiring practitioners to actively reframe and legitimate their respective industry. Using Event Structure Analysis, I model and compare the development of each industry based on linear historical narratives. The resulting models illustrate the importance of events within each narrative along with their relationship to each other. Findings suggest that the creation of industry-wide professional organizations is integral to changing public perception of a given industry. Furthermore, findings show that the more hierarchical structure of the cosmetic surgery industry, as well as its integration into the medical industry, have helped it to thrive in a manner that contrasts sharply with the more disorganized structure of the tattoo industry.     

Marked Difference: Tattooing and its Association with Deviance in the United States

Despite historical associations with deviance and marginality, tattooing is practiced by a diverse population in the United States today, leading some to argue that it has grown beyond its negative associations. Drawing on a nationally representative data set (n = 500) comprised of both tattooed and non-tattooed respondents, this analysis examines the social characteristics of those who are tattooed and the associations of tattooing with deviant behavior. Findings indicate that while tattooing has developed a broad demographic appeal, there remain some strong associations with deviance, particularly criminality. Specifically, highly visible placement of tattoos appears to be most strongly associated with deviant behaviors.     

Preliminary Psychometric Evidence for Distinct Affective and Cognitive Mechanisms Mediating Contamination Aversion

Contamination aversion is implicated in a range of psychological disorders, such as obsessive-compulsive disorder and health anxiety. Despite broad implications, the core mechanisms mediating contamination aversion are mixed and have not clearly been elucidated. The present studies are psychometric investigations of the components of contamination aversion and tests of the different mechanisms that mediate the severity of these components. In Study 1, items from existing measures of contamination aversion were compiled into one measure and administered to a large sample of nonclinical participants (N?=?1,286). Exploratory factor analyses demonstrated a two-factor structure, with one factor comprised of items related to intrinsically (direct) contaminated objects and the other factor comprised of items related to extrinsically (indirect) contaminated objects. In Study 2, items were added and confirmatory factor analyses supported a two-factor model in another large nonclinical sample (N?=?612). In Study 3 (N?=?471), structural modeling demonstrated distinct relations between the two factors and affective and cognitive constructs. Affective constructs related more to aversions toward more directly contaminated objects and situations while cognitive constructs related more to aversions toward more indirectly contaminated objects and situations. The present studies help clarify and articulate the unique roles of cognition and affect in specific contamination aversions, and, as such, have important implications for conceptual modeling of contamination-related psychopathology.     

Behavioral control of exercise in adults: Studies 7 and 8

Abstract

Building on our previous six study series, the current studies 7 and 8 evaluated behavioral methods of improving adherence to exercise in adults. The studies tested the effectiveness of a single exercise modality versus choice of a variety of exercises and were conducted as part of a 12-week extended studies college course in San Diego, CA. Recruitment efforts were targeted to individuals who reported that they were sedentary and/or had experienced difficulty adhering to regular exercise. Participants were 42 adults (32F, 10M; mean age = 42.0) in Study 7 and 48 adults (35F, 8M; mean age = 47.9) in Study 8. In each study, subjects were randomly assigned to a single focus or variety exercise condition. There were no significant group differences in class attendance or out-of-class exercise adherence rates in Studies 7 or 8. In Study 7, significantly lower drop-out rates were detected in the single focus group (19%) than the variety condition (47.6%) (p = 0.04). No significant group differences were detected for drop-out rates in Study 8. Suggestions for further research are offered.     

The Field of Science and Religion as Natural Philosophy

“Natural philosophy” is an important term from the history of science because it was used to describe the study of nature during medieval and early modern Europe. This article gives an overview of the history of natural philosophy, since the use and eventual disuse of the term helps one to understand the emergence of modern science. Following a suggestion by the historian of science Peter Dear, I argue that the term deserves to be rehabilitated because it draws attention to the complexities of scientific theorizing. The article concludes with an argument that the field of science and religion should be seen as an updated version of natural philosophy.     

The Emerging Church as Corporatization’s Line of Flight

ABSTRACT

In the United States and elsewhere, many religious organizations have adopted structures, mechanisms, and ideologies that can be understood through the concept of corporatization. More than a process, corporatization creates a schema through which social relationships are structured and particular values and beliefs are emphasized (particularly, the valorization of the consumer). The authors of the present article draw on Gilles Deleuze and Felix Guattari’s conceptualization of ‘lines of flight’ to illustrate how the Emerging Church, a new religious movement, has leveraged the discontinuities within corporatization. The participants of this movement do so in order to resist institutionalizing systems that rigidify and indoctrinate participants. The authors use ethnographic field methods to demonstrate how Emerging Church participants rely on the tropes of ‘messiness’ and ‘conversation’ to embrace a radical contingency, to foster dialogue, and to avoid adopting rigid, rationalized systems of meaning.     

Dependence on Visual Feedback During Motor Skill Learning in Alzheimer's Disease

Three experiments examined the role of visual feedback on the performance of a fine motor task, namely the rotary pursuit, in patients with Alzheimer's disease (AD) and healthy older adults. After extensive practice tracking a fully visible target, participants in Experiments 1 and 2 were tested under restricted vision (RV) conditions. In both experiments, the two groups showed a drop in performance when vision was restricted, with AD patients showing a significantly larger decline. Tracking improved significantly in normal controls, but not AD patients across the RV trials after the initial drop. When difficulty of the rotary pursuit task was manipulated in Experiment 3 without restricting vision, AD patients and normal controls showed identical patterns of performance. Consequently, it could be concluded that AD patients in the first two experiments were relying more heavily on visual information for accurate performance of the tracking task than their healthy peers.     

A-Theory for B-Theorists

I attempt to characterize the A-theory of time in such a way as to avoid certain standard objections to it, like those derived from McTaggart's paradox. These objections often arise from conflation of the A-theory with other doctrines which are not entailed by it, but which happen to be held by individual A-theorists. In my view, the A-theory is most defensible when combined with a certain analysis of tense (which I call 'the counterfactual theory of tense'), and with realism about the past and future.     

Executive functions predict conceptual learning of science

We examined the relationship between executive functions and both factual and conceptual learning of science, specifically chemistry, in early adolescence. Sixty‐three pupils in their second year of secondary school (aged 12–13 years) participated. Pupils completed tasks of working memory (Spatial Working Memory), inhibition (Stop‐Signal), attention set‐shifting (ID/ED), and planning (Stockings of Cambridge), from the CANTAB. They also participated in a chemistry teaching session, practical, and assessment on the topic of acids and alkalis designed specifically for this study. Executive function data were related to (1) the chemistry assessment which included aspects of factual and conceptual learning and (2) a recent school science exam. Correlational analyses between executive functions and both the chemistry assessment and science grades revealed that science achievements were significantly correlated with working memory. Linear regression analysis revealed that visuospatial working memory ability was predictive of chemistry performance. Interestingly, this relationship was observed solely in relation to the conceptual learning condition of the assessment highlighting the role of executive functions in understanding and applying knowledge about what is learned within science teaching.
