How does social essentialism affect the development of inter‐group relations?

Psychological essentialism is a pervasive conceptual bias to view categories as reflecting something deep, stable, and informative about their members. Scholars from diverse disciplines have long theorized that psychological essentialism has negative ramifications for inter‐group relations, yet little previous empirical work has experimentally tested the social implications of essentialist beliefs. Three studies (N = 127, ages 4.5–6) found that experimentally inducing essentialist beliefs about a novel social category led children to share fewer resources with category members, but did not lead to the out‐group dislike that defines social prejudice. These findings indicate that essentialism negatively influences some key components of inter‐group relations, but does not lead directly to the development of prejudice.     

An evaluation of crisis hotline outcomes. Part 2: Suicidal callers

In this study we evaluated the effectiveness of telephone crisis services/hotlines, examining proximal outcomes as measured by changes in callers' suicide state from the beginning to the end of their calls to eight centers in the U.S. and again within 3 weeks of their calls. Between March 2003 and July 2004, 1,085 suicide callers were assessed during their calls and 380 (35.0%) participated in the follow-up assessment. Several key findings emerged. Seriously suicidal individuals reached out to telephone crisis services. Significant decreases in suicidality were found during the course of the telephone session, with continuing decreases in hopelessness and psychological pain in the following weeks. A caller's intent to die at the end of the call was the most potent predictor of subsequent suicidality. The need to heighten outreach strategies and improve referrals is highlighted.     

A Social Ecological Conceptual Framework for Understanding Adolescent Health Literacy in the Health Education Classroom

With the rising concern over chronic health conditions and their prevention and management, health literacy is emerging as an important public health issue. As with the development of other forms of literacy, the ability for students to be able to access, understand, evaluate and communicate health information is a skill best developed during their years of public schooling. Health education curricula offer one approach to develop health literacy, yet little is known about its influence on neither students nor their experiences within an educational context. In this article, we describe our experience applying a social ecological model to investigating the implementation of a health education curriculum in four high schools in British Columbia, Canada. We used the model to guide a conceptual understanding of health literacy, develop research questions, select data collection strategies, and interpret the findings. Reflections and recommendations for using the model are offered.     

Family dynamics as predictors of infant disposition

In this longitudinal study of mothers, their families, and their infants, both discriminant and regression analyses showed that prenatal reports of family dynamics predicted infant disposition at 8 months with considerable accuracy. The most important predictive component was organization and consistency within the family unit as well as the dependability of other family members. Possible mechanisms by which family dynamics might affect the infant's developing disposition are discussed.     

Normative Social Role Concepts in Early Childhood

The current studies (N = 255, children ages 4–5 and adults) explore patterns of age‐related continuity and change in conceptual representations of social role categories (e.g., “scientist”). In Study 1, young children's judgments of category membership were shaped by both category labels and category‐normative traits, and the two were dissociable, indicating that even young children's conceptual representations for some social categories have a “dual character.” In Study 2, when labels and traits were contrasted, adults and children based their category‐based induction decisions on category‐normative traits rather than labels. Study 3 confirmed that children reason based on category‐normative traits because they view them as an obligatory part of category membership. In contrast, adults in this study viewed the category‐normative traits as informative on their own (not only as a cue to obligations). Implications for continuity and change in representations of social role categories will be discussed.     

A Review of: “The Fundamentals of Brain Development: Integrating Nature and Nurture. By Joan Stiles.”

Reviews the book The Fundamentals of Brain Development: Integrating Nature and Nurture by Joan Stiles. This volume examines the complex interactions between inheritance and experience by detailing the hows and whys of brain development from conception through adolescence. Weaving together evidence from neuroscience, embryology, genetics, physiology, and psychology, Stiles presents a tour-de-force guide of the metamorphoses that take place in the creation of the mammalian brain—metamorphoses that are often overlooked or misunderstood by an analysis of behavior alone. Throughout, many surprising and counterintuitive findings are set forth. The volume provides a stunning, in-depth, biologically based way of thinking about innateness, learning, and experience for a broader psychology audience.
