A simple questionnaire can change everything: Are strategy choices in coordination games stable?

This paper presents results from an experiment designed to study the effect of self reporting risk preferences on strategy choices made in a subsequently played 2x2 coordination game. The main finding is that the act of answering a questionnaire about one's own risk preferences significantly alters strategic behavior. Within a best response correspondence framework, this result can be explained by a change in either risk preferences or beliefs. We find that self reporting risk preferences induces an increase in subjects' risk aversion while keeping their beliefs unchanged. Our findings raise some questions about the stability of strategy choices in coordination games. --coordination game,questionnaire,risk preferences,beliefs,best response correspondence

Does Yoga Aid in the Reduction of Short-Term Anxiety in Adult Female Breast Cancer Patients?

OBJECTIVE: The objective of this selective EBM review is to determine whether or not yoga aids in the reduction of short-term anxiety in adult female breast cancer patients. STUDY DESIGN: Review of three English language primary studies, published between 2007 and 2010. DATA SOURCES: Two randomized controlled trials (RCTs) and one before and after comparison study were found using PubMed, Medline, and OVID. These studies analyzed yoga intervention in adult female breast cancer patients suffering from anxiolytic effects. OUTCOMES MEASURED: The main outcomes measured were anxiety state level and symptom severity and distress experienced by patients through use of the State Trait Anxiety Inventory (STAI) and subjective symptom checklist. The tools used to assess significance of outcomes measured were p-values, change in mean from baseline, ANOVA F-score, and t-values. RESULTS:All three trials showed a significant decrease in anxiety levels after yoga-based intervention. When yoga intervention was employed in the Raghavenedra et al study, a significant decrease in anxiety levels were found (t-value = -5.18, p CONCLUSIONS: The results of the RCTs and before and after comparison study, demonstrate the yoga practice to be an effective treatment for reducing anxiety in adult female breast cancer patients. The implementation of yoga intervention into the lives of cancer patients results in a reduction of stress and chemotherapy-related symptoms, further reducing anxiety levels. Further research is needed to determine length, intensity, and specific yoga asanas that may yield maximum results and relief from anxiety

Objectification theory predicts college women’s attitudes toward cosmetic surgery

This study investigated cosmetic surgery attitudes within the framework of objectification theory. One hundred predominantlyWhite, British undergraduate women completed self-report measures of impression management, global selfesteem, interpersonal sexual objectification, self-surveillance, body shame, and three components of cosmetic surgery attitudes. As expected, each of the objectification theory variables predicted greater consideration of having cosmetic surgery in the future. Also, as expected, sexual objectification and body shame uniquely predicted socialmotives for cosmetic surgery, whereas self-surveillance uniquely predicted intrapersonal motives for cosmetic surgery. These findings suggest that women’s acceptance of cosmetic surgery as a way to manipulate physical appearance can be partially explained by the degree to which they view themselves through the lenses of sexual and self-objectification
