Howard, A. L., Robinson, M., Smith, G. J., Ambrosini, G. L., Piek, J. P., & Oddy, W. H. (2011). ADHD is associated with a “western” dietary pattern in adolescents. Journal of Attention Disorders, 15, 403-411.
Objective: To examine the relationship between dietary patterns and ADHD in a population-based cohort of adolescents. Method: The Raine Study is a prospective study following 2,868 live births. At the 14-year follow-up, the authors collected detailed adolescent dietary data, allowing for the determination of major dietary patterns using factor analysis. ADHD diagnoses were recorded according to International Classification of Deiseases, 9th Revision coding conventions. Logistic regression was used to assess the relationship between scores for major dietary pattern and ADHD diagnoses. Results: Data were available for 1,799 adolescents, and a total of 115 adolescents had an ADHD diagnosis. Two major dietary patterns were identified: “Western” and “Healthy.” A higher score for the Western dietary pattern was associated with ADHD diagnosis (odds ratio = 2.21, 95% confidence interval = 1.18, 4.13) after adjusting for known confounding factors from pregnancy to 14 years. ADHD diagnosis was not associated with the “Healthy” dietary pattern. Conclusion: A Western-style diet may be associated with ADHD.
Wirth, J. H., Sacco, D. F., Hugenberg, K., & Williams, K. D. (2010). Eye gaze as relational evaluation: Averted eye gaze leads to feelings of ostracism and relational devaluation. Personality and Social Psychology Bulletin, 36, 869-882.
Eye gaze is often a signal of interest and, when noticed by others, leads to mutual and directional gaze. However, averting one’s eye gaze toward an individual has the potential to convey a strong interpersonal evaluation. The averting of eye gaze is the most frequently used nonverbal cue to indicate the silent treatment, a form of ostracism. The authors argue that eye gaze can signal the relational value felt toward another person. In three studies, participants visualized interacting with an individual displaying averted or direct eye gaze. Compared to receiving direct eye contact, participants receiving averted eye gaze felt ostracized, signaled by thwarted basic need satisfaction, reduced explicit and implicit self-esteem, lowered relational value, and increased temptations to act aggressively toward the interaction partner.
Weisz, C., & Wood, L. F. (2005). Social identity support and friendship outcomes: A longitudinal study predicting who will be friends and best friends 4 years later. Journal of Social and Personal Relationships, 22, 416-432.
This longitudinal study tested the hypothesis that social identity support would predict the long-term status of first-year college friendships. Social identity support refers to perceived support for valued aspects of the self that are related to identification with social groups, categories, and roles. First-year undergraduates (N = 100) reported levels of closeness, contact, general support, and social identity support for new same-sex friendships. Logistic regression analyses indicated, as expected, that social identity support predicted whether or not a new friend would be a best friend 4 years later, after controlling for initial levels of closeness, contact, and general relationship-specific social support. Social identity support, however, did not predict status as a mere friend at follow-up. The results regarding best friend status suggest that social identity support may be a unique form of social support that contributes to the development of close relationships.
