Information processing biases and panic disorder: relationships among cognitive and symptom measures

To test cognitive models of panic disorder, a range of information processing biases were examined among persons with panic disorder (N=43) and healthy control participants (N=38). Evidence for automatic associations in memory was assessed using the Implicit Association Test, interference effects related to attention biases were assessed using a modified supraliminal Stroop task, and interpretation biases were assessed using the Brief Body Sensations Interpretation Questionnaire. In addition, the relationship between information processing biases and clinical markers of panic (including affective, behavioral, and cognitive symptom measures) was investigated, along with the relationships among biases. Results indicated more threat biases among the panic (relative to control) group on each of the information processing measures, providing some of the first evidence for an implicit measure of panic associations. Further, structural equation modeling indicated that the information processing bias measures were each unique predictors of panic symptoms, but that the bias indicators did not relate to one another. These findings suggest that cognitive factors may independently predict panic symptoms, but not covary. Results are discussed in terms of their support for cognitive models of panic and the potential for automatic versus strategic processing differences across the tasks to explain the low relationships across the biases.     

I am going to gag: Disgust cognitions in spider and blood-injury-injection fears

There is mounting evidence that disgust plays an important role in certain anxiety disorders, yet little is known about disgust's cognitive component. The current study introduces a measure of cognitions associated with disgust and contamination to assess the role of disgust-specific primary and secondary appraisals in phobic responding. A multi-modal assessment of blood-injury-injection (BII) and spider phobia was conducted using BII (N=29) and spider (N=30) fearful groups, and a non-fearful control group (N=30). The Disgust Cognitions scale showed good reliability and validity, and distinguished among the groups. For example, relative to the other groups, the spider fear group reported higher disgust cognitions following presentation of a live spider, whereas the BII Fear group reported higher disgust cognitions following a surgery video. Moreover, the scale was associated with multiple phobic indicators (behavioral avoidance, subjective distress, symptom endorsement), suggesting cognitions may be critical to understanding how disgust contributes to anxiety disorders.     

Differences in Black and White American College Students�� Attitudes Toward Lesbians and Gay Men

Differences in attitudes toward lesbians and gay men (ATLGM) held by Black and White Americans have rarely been studied systematically despite anecdotal evidence suggesting that Black Americans may be less accepting of lesbians and gay men than are White Americans. We tested the hypothesis that Black American??s ATLGM would be less positive than White Americans?? using data collected from 60 Black (36 female, 24 male) and 62 White (25 female, 37 male) students from a public university in the Midwestern United Sates. We found that Black students held generally neutral ATLGM whereas White students?? attitudes were slightly positive. This difference was mediated by racial group differences in right-wing authoritarianism.     

On diffusion and interfacial enrichment of boron in the Laves phase: an in situ TEM-heat-treatment study on newly developed 3Co–3W–9Cr steel

Using in situ transmission-electron-microscopy (TEM) heating and subsequent energy-filtered TEM (EF-TEM) and high-resolution-TEM (HR-TEM) analysis on a newly developed 3Co–3W–9Cr steel, enrichment of boron at the Fe₂W and matrix interface has been studied for the first time. The heat treatment has been carried out at a temperature of 770°C. From the EF-TEM analysis, it is confirmed that a stacking-fault-assisted diffusion mechanism is responsible for enrichment of boron at the interface. From the HR-TEM study, it is ascertained that the diffusion behaviour of boron in the Laves phase and the extent of the enrichment at the interface is dependent on the amount of stacking faults in the Laves phase.     

Diagnostic and Assessment Findings: A Bridge to Academic Planning for Children with Autism Spectrum Disorders

Increasing numbers of children diagnosed and treated for autism spectrum disorders (ASDs) has impacted both neuropsychologists and educators. Though both play key evaluative and treatment roles, there is no available method or process in place enabling the translation of the neuropsychological report recommendations into a format educational teams can easily use, leading to a gap between neuropsychological recommendations and educational planning. In the following, we review the areas evaluated by a neuropsychologist when assessing a child with an ASD, discuss the domains targeted by educational teams when designing an educational plan, and then present a process that has met with some success creating a "bridge" between the diagnostic/assessment process and the subsequent academic planning. Though presented in the context of ASD, the process described can be used by neuropsychologists for various populations to facilitate partnerships with educators that result in improved care for the child.
