The Protective Role of Teacher Preference for At‐Risk Children's Social Status

Aggressive behaviors have been associated with social costs (e.g., rejection) and benefits (e.g., popularity) in previous studies. The current study sought to examine the moderating effect of teacher preference on the association between distinct forms of aggressive behavior (i.e., physical aggression and relational aggression) and social status (i.e., rejection and popularity), and to explore whether these associations differed for boys and girls. Fourth and fifth grade students (N = 193) completed peer nomination procedures to assess rejection and aggressive behavior and teachers provided self‐reports of their preferences for their students. Findings indicated that relationally aggressive girls were more likely to be popular with their peers when their teachers also liked them. In addition, both relationally and physically aggressive girls were less likely to be rejected by their peers when their teachers liked them. Although physical aggression was most strongly associated with rejection among boys whose teachers liked them, relational aggression predicted popularity among boys whose teachers disliked them. Results suggest that teacher preferences may be a particularly important factor contributing to both physically and relationally aggressive children's social status (e.g., rejection and popularity), especially for girls.

Linguistic correlates of social anxiety disorder

The goal of this study was to examine the linguistic correlates of social anxiety disorder (SAD). Twenty-four individuals with SAD (8 of them with a generalised subtype) and 21 non-anxious controls were asked to give speeches in front of an audience. The transcribed speeches were examined for the frequency of negations, I-statements, we-statements, negative emotion words, and positive emotion words. During their speech, individuals with either SAD subtype used positive emotion words more often than controls. No significant differences were observed in the other linguistic categories. These results are discussed in the context of evolutionary and cognitive perspectives of SAD.     

Making decisions about now and later: Development of future-oriented self-control

This study explored factors underlying preschoolers’ ability to make future-oriented choices. In a delay-of-gratification choice task, quantity and visibility of the reward was systematically varied. Participants included 90 typically developing children aged 2–4 years. Children made more choices to delay gratification as the quantity of the reward increased from 1 to 4 stickers, but covering the reward did not have an effect. The study extends previous findings on delay of gratification choice tasks in suggesting a developmental pattern beginning with an early appearing “hot” motivational system. Having children think about the present self versus the future self presumably activates a second “cool” representational system. Age differences in the development of this system and its integration with the motivational system may be at the heart of the “U” shaped function observed in the present work, one in which simpler abilities underlying self-control develop in parallel and integrate to produce more complex behaviour. The study thus contributes to our understanding of the development of future-oriented self-control, a milestone central to socialization and the definition of the self.     

Somatoform Disorder: Treatment Utilization and Cost by Mental Health Professions

Administrative data from Cigna for 149 somatoform cases were analyzed to determine the cost, number of sessions, dropout rates, and recidivism rates. Comparisons on these outcomes were made between medical doctors, psychologists, master’s nurses, master’s social workers, marriage and family therapists, and professional counselors. Recidivism rates and number of sessions are higher than for other mental health problems. There were no significant difference in total cost by profession, but did indicate a significant difference in cost per session for MDs. Analyses indicate that masters and doctoral level providers produced the same drop out and recidivism rates.     

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.     

Fuzzy sets to describe driver behavior in the dilemma zone of high-speed signalized intersections

The Type II dilemma zone describes a segment of road on the approach to a signalized intersection where, if occupied by a motorist presented with the circular yellow indication, is likely to result in a motorist having difficulty deciding to stop at the stop line or proceed through the intersection. This phenomenon results in increased frequency of three failure conditions: rear-end collision at the stop line (excessive deceleration rates), the more severe right-angle crashes in the intersections, and left-turn head-on collisions (both resulting from incorrect estimates of clearance time). A more effective boundary definition for Type II dilemma zones could contribute to the safe design of signalized intersections. The prevailing approaches to dilemma zone delineation include the consideration of the vehicle’s travel time to the stop line or the driver’s likelihood of stopping at a particular distance from the stop line. The imprecision of the driver’s perception of speed and distance suggest that fuzzy logic may contribute to the identification of the Type II dilemma zone boundaries. A fuzzy logic (FL) model was constructed and validated from driver’s empirically observed behavior at high-speed signalized intersections. The research resulted in an increased understanding of the phenomenon which, when applied to the timing of signals and the placement of vehicle detection, can improve the overall safety of signalized intersections.     

There are stable individual differences in performance variability, both from moment to moment and from day to day

Individual differences in decision speed have been regarded as direct reflections of a "primitive" functional neurophysiological characteristic, which affects performance on all cognitive tasks and so may be regarded as the "biological basis of intelligence", or of age-related changes in mental abilities. More detailed analyses show that variability within an experimental session (WSV) is a stable individual difference characteristic and that mean choice reaction times (CRTs) are gross summary statistics that reflect variability, rather than maximum speed of performance. A total of 98 people aged from 60 to 80 years completed 36 weekly sessions on six different letter categorization tasks. After effects of practice and of circadian variability had been eliminated, individuals with lower scores on the Cattell Culture Fair intelligence test had slower CRTs and greater WSV on all tasks. A simulation study showed that the greater WSVs of low Cattell scorers led directly to the significantly greater variability of their mean CRTs from session to session. However because CRTs on tasks co-varied from session to session it was apparent that, besides being affected by WSV, individuals' between-session variabilities (BSVs) also vary because of state changes that affect their performance from day to day. It seems that both variability in performance from trial to trial during a session and variability in average performance from day to day are correlated, stable, individual difference characteristics that vary inversely with intelligence test performance. Methodological consequences of these results for interpretations of age-related cognitive changes, for variability between as well as within individuals, for individual differences in decision speed, and for circadian variability in performance are discussed.
