N200, N250r, and N400 event-related brain potentials reveal three loci of repetition priming for familiar names

The authors assessed immediate repetition effects on event-related potentials (ERPs) while participants performed familiarity decisions for written personal names. For immediately repeated familiar names, the authors observed 3 distinct ERP modulations. At 180-220 ms, a posterior N200 effect occurred for names preceded by same-font primes only. In addition, an increased left temporal negativity (N250r, 220-300 ms) and a reduced central-parietal negativity (N400, 300-400 ms) were seen both for same-font and different-font repetitions. In a 2nd experiment, when names were preceded by either their corresponding face or the face of a different celebrity, only the N400 effect was preserved. These findings suggest that the N200, N250r, and N400 effects reflect facilitated processing at font-specific featural, lexical, and semantic levels of processing, respectively.     

Confirmatory factor analysis of the WMS-III in patients with temporal lobe epilepsy

Five competing models specifying the factor structure underlying the Wechsler Memory Scale-Third Edition (D. Wechsler, 1997b) primary subtest scores were evaluated in a sample of patients with intractable temporal lobe epilepsy (N = 254). Models specifying separate immediate and delayed constructs resulted in inadmissible parameter estimates and model specification error. There were negligible goodness-of-fit differences between a 3-factor model of working memory, auditory memory, and visual memory and a nested--more parsimonious--2-factor model of working memory and general memory. The results suggest that specifying a separate visual memory factor provides little advantage for this sample--an unexpected finding in a population with lateralized dysfunction, for which one might have predicted separate auditory and visual memory dimensions.     

Social psychology of mental health: the social structure and personality perspective

Previous research has revealed a persistent association between social structure and mental health. However, most researchers have focused only on the psychological and psychosocial aspects of that relationship. The present paper indicates the need to include the social and structural bases of distress in our theoretical models. Starting from a general social and psychological model, our research considered the role of several social, environmental, and structural variables (social position, social stressors, and social integration), psychological factors (self-esteem), and psychosocial variables (perceived social support). The theoretical model was tested working with a group of Spanish participants (N = 401) that covered a range of social positions. The results obtained using structural equation modeling support our model, showing the relevant role played by psychosocial, psychological and social, and structural factors. Implications for theory and intervention are discussed.     

A Lay Perspective on the Accuracy of Eyewitness Testimony1

To understand more about what laypeople think they “know” about eyewitness testimony, 276 jury-eligible university students were asked to indicate what factors they believe affect the accuracy of eyewitness testimony. In contrast to the large proportion of eyewitness-memory research that concerns system variables, the lay respondents overwhelmingly generated factors related to estimator variables, while system-variable factors such as police questioning and identification procedures were rarely mentioned. Respondents also reported that their own common sense and everyday life experiences were their most important sources of information about the accuracy of eyewitness testimony. Not only do these results clarify the need for further research on the lay perspective of eyewitness testimony, but they also provide some insight into the way in which many jurors might approach cases involving eyewitness evidence.     

Adaptation and vulnerability in high-risk adolescents: An examination of environmental mediators

The relationship of characteristics of the social environment to the adaptation of adolescents from high-risk predisposing environments was examined. Specifically, the degree to which adolescents' perceptions of various dimensions of their family and school environment as well as sources of social support related to differential levels of personal well-being and academic adjustment was explored. Multiple regression analyses revealed differences in the salience of the dimensions of the social environment as a function of the particular sphere of functioning under consideration. Implications of the findings for developing a model for understanding the relative vulnerability of individuals at risk as well as of the design of preventive interventions are discussed.     

WHO FILLS OUT A LESBIAN QUESTIONNAIRE?

Most research on lesbians has used self-report questionnaires, and assumed that respondents who complete a lesbian questionnaire self-identify as lesbians and engage in sexual relationships with women. The present study examined the degree to which 2,393 women who answered a Lesbian Wellness Survey are distributed on five aspects of lesbian sexuality and the coming-out process. The five aspects were: (a) Sexual Orientation (numerical rating of sexual identity from exclusively lesbian/gay to exclusively heterosexual); (b) Years Out (length of time of self-identity as lesbian/gay/bisexual); (c) Outness/Disclosure (amount of disclosure of sexual orientation to others); (d) Sexual Experience (proportion of sexual relationships with women); and (e) Lesbian Activities (extent of participation in lesbian community events). Mild but significant correlations were found among these dimensions, indicating that being lesbian is not a homogeneous experience. Closer examination by the demographic characteristics of race/ethnicity and age revealed a diversity of experience. African American, Native American, and Latina respondents had moderate correlations among these aspects of lesbian experience, whereas White and Asian American respondents evidenced only mild or nonsignificant correlations. The results indicate that researchers who are studying one aspect of the lesbian experience (e.g., outness to others) need to ensure that they are not assuming such behavior based on other dimensions (such as frequent participation in lesbian community activities or years of being out), especially among White and Asian American lesbians.     

Entre Nosotros: Exploring Latino Diversity in Family Therapy Literature

The term Latino is often used to describe a largely diverse group of individuals living in the United States. This very broad term minimizes within-group differences due to race, ethnicity, class, country of origin and impact of immigration. We conducted a content analysis of 78 articles from peer reviewed journals in the fields of family therapy and family studies focused on Latinos, published from 2000 to May 2010, to challenge the Theoretical Myth of Sameness. We describe our evaluation and offer a culturally sensitive clinical and research approach with Latinos.
