Dogfighting: Symbolic Expression and Validation of Masculinity

This study examines the issue of masculinity indogfighting. Dogfighting is an illegal gaming sportcentered in the Southern United States. The data for thisstudy were obtained via ethnographic fieldwork over a period of two years. Interviews wereconducted with 31 dogmen, approximately 90% of whom werewhite males. In addition the authors attended 14dogfights and numerous pre-fight meetings. We argue that specific elements of this sport representsymbolic attempts at attaining and maintaining honor andstatus, which, in the (predominantly white, male,working-class) dogfighting subculture, are equated with masculine identity. We further argue thatpursuit of symbolic masculinity through dogfighting ismore important to working-class men, who possess feweralternative avenues for achieving status than do middle-class or professional men. Theimplications of this research for the larger culture ofmasculinity in the United States are alsoexplored.     

The value of emotionally expressive visual art in medical education

This paper approaches the topic of visual art in medical education from a philosophical perspective, drawing on arguments from epistemology, philosophy of science, aesthetics, and contemporary ethical theory. Several medical ethicists have noted that the traditional clinical paradigm may increase the epistemic and emotional distance between patient and physician in part by focusing on the physical body and medical technology. Some of these same writers recommend a new approach to patients based on empathy and increased attention to suffering. After reviewing these arguments, supporting examples, and recommendations, I explain how visual art that expresses or symbolizes the emotional response to illness could be used to introduce an additional paradigm into medical education. This would be a paradigm based on empathetic attention to patients' emotional experiences in illness. My own argument is that this additional way of perceiving and relating to patients may reduce the distance between patient and physician and may allow physicians to better meet the ideal of treating the patient as a person.     

Conditions for Facelike Expertise With Objects: Becoming a Ziggerin Expert—but Which Type?

ABSTRACT— Compared with other objects, faces are processed more holistically and with a larger reliance on configural information. Such hallmarks of face processing can also be found for nonface objects as people develop expertise with them. Is this specifically a result of expertise individuating objects, or would any type of prolonged intensive experience with objects be sufficient? Two groups of participants were trained with artificial objects (Ziggerins). One group learned to rapidly individuate Ziggerins (i.e., subordinate-level training). The other group learned rapid, sequential categorizations at the basic level. Individuation experts showed a selective improvement at the subordinate level and an increase in holistic processing. Categorization experts improved only at the basic level, showing no changes in holistic processing. Attentive exposure to objects in a difficult training regimen is not sufficient to produce facelike expertise. Rather, qualitatively different types of expertise with objects of a given geometry can arise depending on the type of training.     

The Viability of Organizational Wellness Programs: An Examination of Promotion and Results

Wellness programs in contemporary organizations are increasing in number, but attendance is low and results often are difficult to track. We examined participant and program characteristics in 2 organizations that offered extensive wellness activities. One organization considered its program successful and had been in operation for 10 years, while the other organization's program ran for 2 years and ended because of a lack of funding. In the successful program, wellness program attendance showed a relationship to time employees took off for sick days, and improved fitness produced similar results. In the less successful operation, interviews were held with mangers and employees regarding promotion and program support. Suggestions are provided for future wellness programs.     

An early electrophysiological response associated with expertise in letter perception

Expertise with print is likely to optimize visual processes for recognizing characters of a familiar writing system. Although brain activations have been identified for words and letter strings in contrast with other stimuli, relatively little work has focused on the neural basis of single-letter perception. English readers and Chinese-English bilinguals participated in an ERP study and performed a 1-back identity judgment on Roman letters, Chinese characters, pseudofonts, and their string versions. The Chinese-English bilinguals showed an enhanced N170 for both Roman letters and Chinese characters relative to pseudofonts. For the non-Chinese readers, the N170 amplitude was larger for Roman letters relative to Chinese characters and pseudofonts. Our results suggest that changes in relatively early visual processes underlie expert letter perception.     

Letter processing in the visual system: different activation patterns for single letters and strings

One would expect that a lifetime of experience recognizing letters would have an important influence on the visual system. Surprisingly, there is limited evidence of a specific neural response to letters over visual control stimuli. We measured brain activation during a sequential matching task using isolated characters (Roman letters, digits, and Chinese characters) and strings of characters. We localized the visual word form area (VWFA) by contrasting the response to pseudowords against that for letter strings, but this region did not show any other sign of visual specialization for letters. In addition, a left fusiform area posterior to the VWFA was selective for letter strings, whereas a more anterior left fusiform region showed selectivity for single letters. The results of different analyses using both large regions of interest and inspections of individual patterns of response reveal a dissociation between selectivity for letter strings and selectivity for single letters. The results suggest that reading experience fine-tunes visual representations at different levels of processing. An important conclusion is that the processing of nonpronounceable letter strings cannot be assumed to be equivalent to single-letter perception.     

Expertise training with novel objects leads to left-lateralized facelike electrophysiological responses

Scalp event-related potentials (ERPs) in humans indicate that face and object processing differ approximately 170 ms following stimulus presentation, at the point of the N170 occipitotemporal component. The N170 is delayed and enhanced to inverted faces but not to inverted objects. We tested whether this inversion effect reflects early mechanisms exclusive to faces or whether it generalizes to other stimuli as a function of visual expertise. ERPs to upright and inverted faces and novel objects (Greebles) were recorded in 10 participants before and after 2 weeks of expertise training with Greebles. The N170 component was observed for both faces and Greebles. The results are consistent with previous reports in that the N170 was delayed and enhanced for inverted faces at recording sites in both hemispheres. For Greebles, the same effect of inversion was observed only for experts, primarily in the left hemisphere. These results suggest that the mechanisms underlying the electrophysiological face-inversion effect extend to visually homogeneous nonface object categories, at least in the left hemisphere, but only when such mechanisms are recruited by expertise.     

When intuition fails to align with data: A reply to Rossion (2013)

Holistic processing, a hallmark of face perception, is often measured in the so-called composite paradigm, in which participants are asked to match part of a stimulus while ignoring another part. In prior work, we recommended against the use of one version of the composite task we call the partial design, on the basis of confounds with response biases. Rossion wrote a lengthy piece that reviews the work that he has published using this design, raising a large number of criticisms, both about an alternative measure of holistic processing that we have used and advocated (which we call the complete design) and about our work in general. In this reply, we have limited our discussion to those issues that would be relevant to a researcher looking to decide which version of this composite paradigm to use, as we doubt a comprehensive reply would be of significant interest outside a very small circle.     

The contribution of social rank and attachment theory to depression in a non clinical sample of adolescents

This study explores the relative contribution of the overall quality of attachment to the mother, to the father and to peers (Inventory of Parent and Peer Attachment scales), the style of attachment towards peers (Attachment Questionnaire for Children scale), the social rank variables (submissive behavior and social comparison), and sex and age variables in predicting the depression score (Center of Epidemiological Studies Depression Scale) on a non-psychiatric sample of 13-18 year old adolescents (n = 225). Results of our integrated model (adjusted R-Square of .50) show that attachment variables (overall quality of attachment to the father and to the mother), social rank variables (social comparison and submissive behavior), age and sex are important in predicting depressive symptoms during adolescence. Moreover, the attachment to peers variables (quality of attachment to peers, secure and ambivalent style of attachment) and sex are mediated by the social rank variables (social comparison and submissive behavior).     

Indecision on decisional separability

The theoretical framework of General Recognition Theory (GRT; Ashby & Townsend, Psychological Review, 93, 154-179, 1986) coupled with the empirical analysis tools of Multidimensional Signal Detection Analysis (MSDA; Kadlec & Townsend, Multidimensional models of perception and recognition, pp. 181-228, 1992) have become one important method for assessing dimensional interactions in perceptual decision-making. In this article, we critically examine MSDA and characterize cases where it is unable to discriminate two kinds of dimensional interactions: perceptual separability and decisional separability. We performed simulations with known instances of violations of perceptual or decisional separability, applied MSDA to the data generated by these simulations, and evaluated MSDA on its ability to accurately characterize the perceptual versus decisional source of these simulated dimensional interactions. Critical cases of violations of perceptual separability are often mischaracterized by MSDA as violations of decisional separability.
