Thinness and eating expectancies predict subsequent binge-eating and purging behavior among adolescent girls

One's expectancies for reinforcement from eating or from thinness are thought to represent summaries of one's eating-related learning history and to thus influence the development of binge-eating and purging behavior. In a 3-year longitudinal study, the authors tested this hypothesis and the hypothesis that binge eating also influences subsequent expectancy development. The authors used trajectory analysis to identify groups of middle school girls who followed different trajectories of binge eating, purging, eating expectancies, and thinness expectancies. Initial eating and thinness reinforcement expectancies identified girls whose binge eating and purging increased during middle school, and expectancies differentiated girls who began these problem behaviors from girls who did not. Initial binge-eating scores differentiated among eating expectancy developmental trajectories. The onset of most behaviors can be understood in terms of learned expectancies for reinforcement from these behaviors. The same model can be applied to the risk for eating disorders.     

To Use or Not to Use: The Prenatal Genetic Technology/Worry Conundrum

We conducted an exploratory, qualitative study investigating the factors influencing the use of genetic counseling and prenatal genetic testing for two groups: pregnant women 35 years of age and over (AMA) at the time of delivery and pregnant women with an abnormal maternal serum triple screen (MSAFP3). The convenience sample consisted of 25 semistructured interviews of women/couples and 50 observations of genetic counseling sessions. Worry turned out to be the most important variable influencing decision making about prenatal genetic testing and was greater in the MSAFP3 group than in the AMA group. The women in the AMA group appeared to assign the risk of having a child with Down syndrome to their age category rather than to themselves individually, whereas, the risk perception for women with an abnormal MSAFP3 appeared to have shifted from a general population risk for pregnant women to an individual, personal risk. There was a general lack of understanding and also more misinformation about the MSAFP3 screen compared to amniocentesis. Women in both groups were torn between fear of an invasive test and worry about the health of their fetus for the rest of their pregnancy if they did not undergo amniocentesis.     

Adolescent Perception of Peer Success: A Gendered Perspective over Time

Adolescent males and females (grades 6–12) (n = 552) were presented with nine brief vignettes from the Teen Apperception Scale, describing high-achieving hypothetical female (or male) peers, across nine domains: leadership, academics, athleticism (two), musicianship, art, popularity, humor, and multitalentedness. Teens rated likability, popularity, and attractiveness of vignette subjects in each domain. The sample was roughly evenly divided by gender (47% male and 53% female); students ranged in age from 11 to 18 years. The sample was ethnically diverse, and the socioeconomic status of the students' families ranged from lower middle to upper middle class. MANOVA analyses showed female vignette subjects to be rated significantly higher than male subjects by both genders and all grade groupings, at p < .0001 overall, and at values ranging from p < .05 to p < .0001 for six of nine subscales. Results are contrasted with those from highly similar studies 30 years ago, and used to reflect a possible shift in attitudes toward high achievement in women.     

Examining the Role of Implicit Emotional Judgments in Social Anxiety and Experiential Avoidance

This study sought to examine the relationship of implicit emotional judgments with experiential avoidance (EA) and social anxiety. A sample of 61 college students completed the Emotional Judgment – Implicit Relational Assessment Procedure (EJ-IRAP) as well as a public speaking challenge. Implicit judgments were related to greater self-reported EA, anxiety sensitivity, emotional judgments and social anxiety as well as lower performance ratings and willingness in the public speaking challenge. Effects differed by trial type with “Anxiety is bad” biases related to greater EA/anxiety, while “calm is bad” biases related to lower EA/anxiety (“Good” biases were generally unrelated to outcomes). Implicit emotional judgments moderated the relationship of heart rate during the speech with speech time and willingness, such that increases in heart rate were only related to lower speech time and willingness among those high in implicit judgments. Implicit judgments predicted social anxiety above and beyond self-report EA measures. Implicit emotional judgments appear to have a functional role in EA and anxiety that warrants further research.     

Properties,laws, and worlds

Jonathan Schaffer argues against a necessary connection between properties and laws. He takes this to be a question of what possible worlds we ought to countenance in our best theories of modality, counterfactuals, etc. In doing so, he unfairly rigs the game in favor of contingentism. I argue that the necessitarian can resist Schaffer’s conclusion while accepting his key premise that our best theories of modality, counterfactuals, etc. require a very wide range of things called ‘possible worlds’. However, the necessitarian can and should insist that, in many cases, these worlds are not metaphysically possible. I will further argue that, having taken such a stance, the necessitarian has additional resources to respond to Schaffer’s other arguments against the view.     

Teacher implementation of precorrection and praise statements in Head Start classrooms as a component of a program-wide system of positive behavior support

Although research has clearly supported the use of school-wide positive behavior support (PBS) in elementary school settings, data-based research has not been conducted to support program-wide PBS in early childhood settings. The purpose of this study was to specifically support teachers’ use of universal features of program-wide PBS and to determine whether increases in the use of positive teacher behaviors, including precorrection and praise, were functionally related to decreases in students’ problem behavior. Using a multiple baseline design, three teachers were introduced to an intervention to increase their use of precorrections and specific behavioral praise statements. A relationship was established between the three teachers’ use of key features of program-wide PBS and the reduction of students’ problem behavior in a small group setting. However, findings should be viewed as tentative and future research should explore the relative influence of each of the intervention components on preschool students’ behavior.     

Linking team resources to work-family enrichment and satisfaction

Work-family scholars now recognize the potential positive effects of participation in one life domain (i.e., work or family) on performance in other life domains. We examined how employees might benefit from team resources, which are highly relevant to the modern workplace, in both work and nonwork domains via work-family enrichment. Using the Resource-Gain-Development model (Wayne, Grzywacz, Carlson, & Kacmar, 2007), we explored how team resources contribute to enrichment and resulting project and family satisfaction. Using multilevel structural equation modeling (ML-SEM) to analyze student data (N = 344) across multiple class projects, we demonstrated that individuals with team resources were more likely to experience both work-to-family and family-to-work enrichment. Further, enrichment mediated the relationship between team resources and satisfaction with the originating domain.
