Site visits in interfaith and religious studies pedagogy: Reflections on visiting a Hindu temple in central Pennsylvania

Site visits provide an irreplaceable learning experience to students in both religious studies and the emerging field of interfaith studies. The conceptual core of this thesis is the claim, drawn from feminist epistemology, that an embodied pedagogy – a pedagogy which engages students not only intellectually, but as embodied beings who inhabit a space, engage in physical activities, and undergo various sensory experiences – is ultimately more enriching than a pedagogy centered exclusively in the classroom. Factors that make a site visit a successful instance of embodied pedagogy include the provision of sufficient context to students in advance for them to understand and appreciate the experience, an opportunity afterward to reflect on this experience in an intentional way, ensuring the site and the community whose space it is are treated with proper respect, and ensuring that the religious sensibilities of one's students are also similarly respected.     

Flexible attention allocation to visual and auditory working memory tasks: manipulating reward induces a trade-off

Prominent roles for general attention resources are posited in many models of working memory, but the manner in which these can be allocated differs between models or is not sufficiently specified. We varied the payoffs for correct responses in two temporally-overlapping recognition tasks, a visual array comparison task and a tone sequence comparison task. In the critical conditions, an increase in reward for one task corresponded to a decrease in reward for the concurrent task, but memory load remained constant. Our results show patterns of interference consistent with a trade-off between the tasks, suggesting that a shared resource can be flexibly divided, rather than only fully allotted to either of the tasks. Our findings support a role for a domain-general resource in models of working memory, and furthermore suggest that this resource is flexibly divisible.     

Psychometric properties of an adult ADHD diagnostic interview

Although research has been conducted to support the psychometric properties of rating scales used to assess ADHD in adults, little work has been published examining semi-structured interviews to assess ADHD in adults. The present study examined the test-retest reliability and concurrent validity of the Conners Adult ADHD Diagnostic Interview for Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) in a sample (N = 30) of patients referred to an outpatient clinic. Kappa statistics for individual symptoms of inattention and hyperactivity-impulsivity were in the fair to good range for current report and retrospective childhood report. Kappa values for overall diagnosis, which included all DSM-IV symptoms, were fair for both current (adult) ADHD diagnosis (kappa = .67) and childhood report (kappa = .69). Concurrent validity was demonstrated for adult hyperactive-impulsive symptoms and child inattentive symptoms. The findings are discussed in the context of overall issues pertaining to adult ADHD assessment.     

A metric for the cognitive map: found at last?

A network of brain areas collectively represent location, but the underlying nature of this "cognitive map" has remained elusive. A recent study reports that the activity patterns of some entorhinal cortical neurons form a remarkably regular array of evenly spaced peaks across the surface of the environment. These "grid cells" might be the basis of a metric used for calculating position, and their discovery could greatly advance our understanding of how navigational computations are performed.     

The cognitivist's revenge?

The recent articles by F. Mechsner (2004) and his colleagues (F. Mechsner, D. Kerzel, G. Knoblich, & W. Prinz, 2001) have once again fuelled the cognition vs. motor debate. In this commentary, the author takes an historical perspective and argues that Mechsner' stance represents just another phase in this continuing dialogue. Finally, the value of such false dichotomies in the progress of the field is questioned.     

Visual prosody and speech intelligibility: head movement improves auditory speech perception

People naturally move their heads when they speak, and our study shows that this rhythmic head motion conveys linguistic information. Three-dimensional head and face motion and the acoustics of a talker producing Japanese sentences were recorded and analyzed. The head movement correlated strongly with the pitch (fundamental frequency) and amplitude of the talker's voice. In a perception study, Japanese subjects viewed realistic talking-head animations based on these movement recordings in a speech-in-noise task. The animations allowed the head motion to be manipulated without changing other characteristics of the visual or acoustic speech. Subjects correctly identified more syllables when natural head motion was present in the animation than when it was eliminated or distorted. These results suggest that nonverbal gestures such as head movements play a more direct role in the perception of speech than previously known.     

Eating Disorders in Men: Current Considerations

Over the past two decades, there has been a change in the way men think about their bodies. The media portrays images of men with muscular bodies and a six pack abdomen. These images can create body dissatisfaction in males. With the change in the way that the media and society in the United States look at men, so has the drive for men to achieve this ideal body image. Eating disorders, body dysmorphia, and strict exercise and diet regimens seem to plague young men as do the images in advertisements. Although eating disorders in men are similar to what women experience, men seem to strive for more body mass whereas women try to obtain thinness. Gay men and heterosexual men seem to experience eating disorders in the same way although there are differences between how they perceive their bodies. This paper outlines how the media contributes to body dissatisfaction in men. In addition to understanding how the media affects men, it is important to review and possibly revise out understanding of eating disorders and body dysmorphia symptoms to gain a solid understanding of how these symptoms appear in men today.     

Continuous Performance Test Performance in a Normative Epidemiological Sample

A 14-min continuous performance test (CPT) requiring a high rate of responding was administered to a probability-weighted random sample of 816 9–17-year-old children drawn from a population of 17,117 children in an ongoing epidemiological and longitudinal study in Western North Carolina. Systematic main effects of improved performance with older age were found in this age range for all variables, including reaction time (RT), RT standard error, errors of omission, errors of commission, and signal detection parameters (d' and ). Significant gender main effects included more impulsive errors, less variability, and faster RT by males, with no interactions between age and gender. There were no main effects of ethnicity or interactions of ethnicity with age and/or gender. Large main effects of interstimulus interval (ISI; 1, 2, or 4-s intervals) and time block were present for most CPT performance measures. The normative data from the CPT should provide a useful framework for interpreting similar data in future studies of child and adolescent psychopathology.
