Media Internalization and Social Comparison as Predictors of Eating Pathology Among Latino Adolescents: The Moderating Effect of Gender and Generational Status

Using a sociocultural framework, this cross-sectional study examined eating pathology among 235 Latino adolescents from the Southwestern U.S. who differed in generational status. Participants completed self-report measures of media pressures, internalization, social comparison, and eating pathology. Overall, results revealed stronger relationships between these sociocultural variables and eating pathology for girls. Girls reported greater social comparison, thin-ideal pressure and internalization, and eating pathology than boys. Generational status was positively correlated with these sociocultural variables and eating pathology for girls only. Moderated hierarchical regression analyses indicated that athletic-ideal internalization was a key predictor of eating pathology for girls but not boys. Discussion highlights gender, more than generational status, as critical to a sociocultural framework for eating pathology among adolescent Latino Americans.     

The role of the dorsal CA1 and ventral CA1 in memory for the temporal order of a sequence of odors

Memory for the temporal order of a sequence of odors was assessed in male rats. A sequence of five odors mixed in sand was presented in digging cups one at a time to each rat in a sequence that varied on each trial. A reward was buried in each cup. Following the fifth odor, two of the previous five odors were presented simultaneously and the rat needed to choose the odor that occurred earliest in the sequence to receive a reward. Temporal separations of 1, 2, or 3 were used which represented the number of odors that occurred between the two odors in the sequence. Once pre-operative criterion was reached, rats received a control, dorsal CA1 (dCA1), or ventral CA1 (vCA1) lesion and were retested on the task. On post-operative trials, only the vCA1 group was impaired relative to both control and dCA1 groups. All groups of rats could discriminate between the odors. The data suggest that the vCA1, but not dorsal CA1, is involved in separating sensory events (odors) in time so that one odor can be remembered separate from another odor.     

The mental representation of music notation: notational audiation

This study investigated the mental representation of music notation. Notational audiation is the ability to internally "hear" the music one is reading before physically hearing it performed on an instrument. In earlier studies, the authors claimed that this process engages music imagery contingent on subvocal silent singing. This study refines the previously developed embedded melody task and further explores the phonatory nature of notational audiation with throat-audio and larynx-electromyography measurement. Experiment 1 corroborates previous findings and confirms that notational audiation is a process engaging kinesthetic-like covert excitation of the vocal folds linked to phonatory resources. Experiment 2 explores whether covert rehearsal with the mind's voice also involves actual motor processing systems and suggests that the mental representation of music notation cues manual motor imagery. Experiment 3 verifies findings of both Experiments 1 and 2 with a sample of professional drummers. The study points to the profound reliance on phonatory and manual motor processing--a dual-route stratagem--used during music reading. Further implications concern the integration of auditory and motor imagery in the brain and cross-modal encoding of a unisensory input.     

Meta-analysis of cognitive-behavioral interventions on HIV-positive persons' mental health and immune functioning.

OBJECTIVE: To evaluate the efficacy of cognitive-behavioral interventions (CBIs) for improving the mental health and immune functioning of people living with HIV (PLWH). DESIGN: Comprehensive searches of electronic databases from 1988 to 2005, hand searches of journals, reference lists of articles, and contacts with researchers. Meta-analytic approaches were used in synthesizing findings. MAIN OUTCOME MEASURES: Intervention effects on symptoms of depression, anxiety, and anger, stress, and CD4 cell counts were assessed. RESULTS: Data from 15 controlled trials were analyzed. Significant intervention effects were observed for improving symptoms of depression (d = 0.33), anxiety (d = 0.30), anger (d = 1.00), and stress (d = 0.43). There is limited evidence suggesting intervention effects on CD4 cell counts (d = 0.08). The aggregated effect size estimates for depression and anxiety were statistically significant in trials that provided stress management skills training and had more than 10 intervention sessions. CONCLUSION: CBIs are efficacious in improving various psychological states of PLWH. Future research should examine the relationship among interventions, psychological states, medication adherence, and immune functions, and identify other relevant factors associated with intervention effects.     

Effects of context on eye movements when reading about possible and impossible events

Plausibility violations resulting in impossible scenarios lead to earlier and longer lasting eye movement disruption than violations resulting in highly unlikely scenarios (K. Rayner, T. Warren, B. J. Juhasz, & S. P. Liversedge, 2004; T. Warren & K. McConnell, 2007). This could reflect either differences in the timing of availability of different kinds of information (e.g., selectional restrictions, world knowledge, and context) or differences in their relative power to guide semantic interpretation. The authors investigated eye movements to possible and impossible events in real-world and fantasy contexts to determine when contextual information influences detection of impossibility cued by a semantic mismatch between a verb and an argument. Gaze durations on a target word were longer to impossible events independent of context. However, a measure of the time elapsed from first fixating the target word to moving past it showed disruption only in the real-world context. These results suggest that contextual information did not eliminate initial disruption but moderated it quickly thereafter.     

Pragmatic Narratives of Hysterectomy Among Australian Women

Drawing on a qualitative study based on in-depth interviews with 30 rural and urban Australian women, we analyze their experiences of a hysterectomy for conditions other than cancer. Women were recruited via advertisements in community newspapers and the network sampling technique. The study aimed to identify the personal, social and medical factors that influenced their decision to undergo surgery and on their understandings of self following this procedure. Three common themes emerged: a negative response to a hysterectomy, ambivalence about it and a perceiving it as having a positive impact on the woman’s self. The latter pattern predominated, indicating that contrary to the medical rhetoric, women’s own accounts are different and relevant when counseling women about a hysterectomy.     

Sustaining Male Dominance in Interscholastic Athletics: A Case of Homologous Reproduction…or Not?

To establish if male hegemony continued to exist in high school athletics within the USA and to determine the extent that homologous reproduction (hiring people of the same gender) might be a contributing factor, the administrative structures of 480 high school athletic departments were analyzed. The gender of each school’s principal, athletic director, and coaches were collected from The National Directory of High School Coaches. Male hegemony was found to exist since men dominated both principal (76%) and athletic director (85%) positions, however evidence of homologous reproduction was only evident at the coaching level. The culture of hegemonic masculinity within athletics might be sustained more as a result of sex-role theory or gender-based schematic processing, rather than homologous reproduction.     

Employability of Genetic Counselors with a PhD in Genetic Counseling

The development of a PhD in genetic counseling has been discussed for more than 20 years, yet the perspectives of employers have not been assessed. The goal of this qualitative study was to gain an understanding of the employability of genetic counselors with a PhD in genetic counseling by conducting interviews with United States employers of genetic counselors. Study participants were categorized according to one of the following practice areas: academic, clinical, government, industry, laboratory, or research. All participants were responsible for hiring genetic counselors in their institutions. Of the 30 employers interviewed, 23 envisioned opportunities for individuals with a PhD degree in genetic counseling, particularly in academic and research settings. Performing research and having the ability to be a principal investigator on a grant was the primary role envisioned for these individuals by 22/30 participants. Employers expect individuals with a PhD in genetic counseling to perform different roles than MS genetic counselors with a master's degree. This study suggests there is an employment niche for individuals who have a PhD in genetic counseling that complements, and does not compete with, master's prepared genetic counselors.     

The effects of testosterone on cognition in elderly men: a review

In this article, the literature examining the relationship between testosterone and various cognitive domains in elderly men is reviewed. The review focuses on the role of endogenous testosterone levels and the effects of androgen depletion and replacement. The cognitive domains most commonly linked to testosterone include memory and visuospatial function. Indeed, the literature suggests that in certain conditions (ie, hypogonadism, cognitive impairment) testosterone levels may be significantly associated with memory and visuospatial function, but not other cognitive functions. Studies with larger sample sizes and more sensitive cognitive measures are indicated, as questions remain about the potential role of testosterone as a cognitive enhancer.
