Why is it so hard to change? The role of self-integrity threat and affirmation in weight loss

People are frequently dissatisfied with their body weight. Messages alleging that lower weight is esthetically preferable, healthier, and achievable likely trigger chronic self-integrity threat, the sense that one's personal adequacy is in doubt. We examined whether self-integrity threat, which creates stress and pressure to restore self-integrity, contributes to the challenges of weight and behavior change. Weight-dissatisfied women completed in-lab tasks including a values affirmation manipulation and two-month follow-up. Affirmed women lost weight relative to controls, replicating previous research. Effects were primarily among those with higher initial body masses. Affirmed higher-weighted women also ate more healthful foods compared to unhealthful foods in self-reports and observation. Affirmed participants reported increased exercise, and an exploratory measure showed that their cortisol awakening responses synchronized with their coping needs, suggesting more adaptive physiological function. Results suggest that self-integrity threat is an under-recognized barrier to change, and reducing it can support healthy changes.     

Gruesomeness conveys formidability: Perpetrators of gratuitously grisly acts are conceptualized as larger,stronger, and more likely to win

While associated with extreme terrorist organizations in modern times, extensive accounts of grisly acts of violence exist in the archeological, historical, and ethnographic records. Though reasons for this dramatic form of violence are multifaceted and diverse, one possibility is that violence beyond what is required to win a conflict is a method by which violent actors communicate to others that they are formidable opponents. The formidability representation hypothesis predicts that formidability is cognitively represented using the dimensions of envisioned bodily size and strength. We tested the informational ramifications of gruesome acts using two vignette studies depicting individuals who either did or did not grievously damage the corpse of a deceased foe. Participants rated the individual's height, bodily size, and strength, as well as his aggressiveness, motivation, and the capacity to vanquish opponents in future conflicts. Results indicate that, as predicted, committing gruesome acts of violence enhances perceptions of formidability as measured both by envisioned bodily size and strength and expectations regarding the outcomes of agonistic conflicts. Moreover, the gruesome actor was perceived as more aggressive and more motivated to overcome his enemies, and this mediated the increase in conceptualized size and strength. These results both provide further evidence for the formidability representation hypothesis and support the thesis that overtly grisly violence is tactically employed, in part, because it conveys information about the perpetrator's formidability.     

Do performance avoidance goals moderate the effect of different types of stereotype threat on women’s math performance?

Stereotype threat is considered to be a robust effect that explains persistent gender gaps in math performance and scientific career trajectories. Some evidence suggests stereotype threat effects are buffered by adoption of performance avoidance goals (Chalabaev, Major, Sarrazin, & Cury, 2012). With 590 American female participants, we closely replicated Chalabaev et al. (2012). Results showed no significant main or interaction effects for stereotype threat or performance avoidance goals, despite multiple controls. We conclude that effects of stereotype threat might be smaller than typically reported and find limited evidence for moderation by avoidance achievement goals. Accordingly, stereotype threat might not be a major part of the explanation for the gender gap in math performance, consistent with recent meta-analyses (Flore & Wicherts, 2015).     

Threat perception distortions and psychopathological symptoms in typically developing children

This study examined relationships between symptoms of anxiety, aggression, and depression, on the one hand, and threat perception distortions, on the other hand. A large sample of typically developing children aged 8–12 years (N=157) were interviewed with an instrument for assessing the main types of childhood psychopathology, and were then exposed to a series of ambiguous vignettes in order to measure threat perception. As all measures were obtained twice, some 8 weeks apart, it was also possible to study prospective relationships between threat perception distortions and psychopathological symptoms. Results showed that threat perception was associated with a broad range of psychopathological symptoms, although the connection with anxiety was the most robust. No support was found for the notion that threat perception scores were predictive for the persistence of psychopathological symptoms during the 8‐weeks period. Copyright © 2005 John Wiley & Sons, Ltd.
