The face in the crowd effect unconfounded: happy faces, not angry faces, are more efficiently detected in single- and multiple-target visual search tasks

Is it easier to detect angry or happy facial expressions in crowds of faces? The present studies used several variations of the visual search task to assess whether people selectively attend to expressive faces. Contrary to widely cited studies (e.g., ?hman, Lundqvist, & Esteves, 2001) that suggest angry faces "pop out" of crowds, our review of the literature found inconsistent evidence for the effect and suggested that low-level visual confounds could not be ruled out as the driving force behind the anger superiority effect. We then conducted 7 experiments, carefully designed to eliminate many of the confounding variables present in past demonstrations. These experiments showed no evidence that angry faces popped out of crowds or even that they were efficiently detected. These experiments instead revealed a search asymmetry favoring happy faces. Moreover, in contrast to most previous studies, the happiness superiority effect was shown to be robust even when obvious perceptual confounds--like the contrast of white exposed teeth that are typically displayed in smiling faces--were eliminated in the happy targets. Rather than attribute this effect to the existence of innate happiness detectors, we speculate that the human expression of happiness has evolved to be more visually discriminable because its communicative intent is less ambiguous than other facial expressions.     

Motor timing deficits in children with Attention-Deficit/Hyperactivity disorder

Children with Attention-Deficit/Hyperactivity Disorder (ADHD) are thought to have fundamental deficits in the allocation of attention for information processing. Furthermore, it is believed that these children possess a fundamental difficulty in motoric timing, an assertion that has been explored recently in adults and children. In the present study we extend this recent work by fully exploring the classic Wing and Kristofferson (1973) analysis of timing with typically developing children (n=24) and children with ADHD (n=27). We provide clear evidence that not only do children with ADHD have an overall timing deficit, they also time less consistently when using a similar strategy to typically developing children. The use of the Wing and Kristofferson approach to timing, we argue, will result in the discovery of robust ADHD-related timing differences across a variety of situations.     

Iona College Community Centered Family Health History Project: Lessons Learned from Student Focus Groups

The Community Centered Family Health History project was initiated to create accessible family health history tools produced by and for the community. The project goal was to promote increased community engagement in health education by encouraging conversations among family members that would translate knowledge of family health history into healthy lifestyle choices. As one of seven community partners, Iona College participated in customizing and beta-testing the Does It Run in the Family? toolkit. Twenty-nine college students were engaged to recruit three relatives related by blood to provide feedback on the utility of the toolkit. The toolkit consists of two booklets—“A Guide to Family Health History” and “A Guide to Understanding Genetics and Health”—explaining the importance of knowing and talking about health within the family as well as basics about how conditions are passed down through generations. Twenty-two of the twenty-nine students participated in focus groups to discuss their reactions to participation in the project. Students in the focus group reported that the study participants—students and their family members—found the toolkit to be user friendly and the experience a valuable one that prompted many to take positive steps toward good health.     

Suicide Ideation and Attempts among Inhalant Users: Results from the National Epidemiologic Survey on Alcohol and Related Conditions

Few studies have examined associations of inhalant use and inhalant use disorders (IUDs) to suicide ideation and attempts. We investigated these relationships in the largest comorbidity survey conducted in the United States. Suicidal ideation was significantly more prevalent among inhalant users than nonusers and severity of inhalant use problems was positively related to suicidal ideation. Among persons with IUDs, 67.4% had thought about committing suicide and 20.2% had attempted suicide. Multivariate logistic regression analyses indicated that respondents with IUDs reported significantly higher levels of suicide ideation than inhalant nonusers. Inhalant use is associated with significantly increased risk for suicide ideation, especially among women and persons with DSM‐IV IUDs.     

Student Agency in Literacy: Validation of the Student Agency Profile (StAP)

Abstract

There have been recent calls to support student agency in the field of literacy. Agency, which we define in the context of schooling, is a multidimensional construct where individuals exert influence and create opportunities in the learning context through intentions, decisions, and actions. We propose highlighting agency as an interconnected construct, which includes self-perception as readers and writers, intentionality, choice-making, persistence, and interactiveness. Elementary students (n?=?1,726) completed surveys of their agency along with standardized literacy assessments. Statistical analyses largely aligned with the hypothesized dimensions of agency. Relationships to student literacy achievement were stronger in grades 3^rd–5^th than in 1^st–2^nd grades. Discussion highlights how elementary students have a voice in their agency as it pertains to literacy. Implications for future research and practice are discussed.
