Hemispheric resource availability influences face perception: a multiple resource approach to social perception.

Two experiments tested the hypothesis that social perception recruits distinct limited-capacity processing resources that are distinguished by the cerebral hemispheres. To test this hypothesis, social perception efficiency was assessed after relevant hemispheric processing resources were depleted. In Experiment 1 prime faces were unilaterally presented for 30 ms, after which centrally presented target faces were categorised by sex. In Experiment 2 prime faces were unilaterally presented for 80 ms after which centrally presented target faces were categorised by fame. Results showed that sex categorisation was slower after primes were presented in the right versus left visual field, and that fame categorisation was slower after familiar primes were presented in the left versus right visual field. The results support a multiple resource account of social perception in which the availability of resources distributed across the cerebral hemispheres influences social perception.

Improving Resilience and Combating Burnout in US Army Health Care Teams.

INTRODUCTION: In 2015, the Army Office of the Surgeon General adapted a Veterans Health Administration course for health care teams to implement holistic health practices to improve the resiliency of health care teams and patient care. The Army course Move to Health was piloted in health care teams at 8 military clinics. During the 20-hour course, health care teams learned techniques to improve their resiliency and created action plans to incorporate holistic health into the workplace, a known factor in decreasing burnout. METHODS: A process and outcome evaluation of this course was conducted using a within-group design. Surveys were administered to health care teams at precourse and 2-month follow-up, and 186 participants completed both surveys. RESULTS: Burnout among team members did not significantly change from precourse (52%, n = 96) to follow-up (48%, n = 90). At follow-up, team members described using resiliency building strategies for self-care, significantly improved their self-efficacy to treat patients holistically in the patient-centered care home model, and reported increased satisfaction with patient centered care home (all are p < 0.01). However, 70% (n = 131) of team members reported that they had not completed action plan implementation and did not report improved job satisfaction. DISCUSSION: Informed by the literature, Move to Health combines an individual resiliency intervention with organizational change, facilitating action plans to mitigate burnout. This manuscript explores potential reasons for why burnout did not significantly change within the 2-month period following the intervention. Reducing burnout among health care teams is vital to ensure that optimal health care is provided to the military and its beneficiaries.

An Evaluation of Army Wellness Center Clients' Health-Related Outcomes.

PURPOSE: To examine whether Army community members participating in a best-practice based workplace health promotion program (WHPP) experience goal-moderated improvements in health-related outcomes. DESIGN: Pretest/posttest outcome evaluation examining an autonomously participating client cohort over 1 year. SETTING: Army Wellness Center facilities on 19 Army installations. PARTICIPANTS: Army community members sample (N = 5703), mostly Active Duty Soldiers (64%). INTERVENTION: Assessment of health risks with feedback, health assessments, health education classes, and health coaching sessions conducted by health educators at a recommended frequency of once a month for 3 to 12 months. MEASURES: Initial and follow-up outcome assessments of body mass index (BMI), body fat, cardiorespiratory fitness, blood pressure, and perceived stress. ANALYSIS: Mixed model linear regression testing for goal-moderated improvements in outcomes. RESULTS: Clients experienced significant improvements in body fat (-2% change), perceived stress (-6% to -12% change), cardiorespiratory fitness (+6% change), and blood pressure (-1% change) regardless of health-related goal. Only clients with a weight loss goal experienced BMI improvement (-1% change). Follow-up outcome assessment rates ranged from 44% (N = 2509) for BMI to 6% (N = 342) for perceived stress. CONCLUSION: Army Wellness Center clients with at least 1 follow-up outcome assessment experienced improvements in military readiness correlates and chronic disease risk factors. Evaluation design and follow-up-related limitations notwithstanding results suggest that best practices in WHPPs can effectively serve a globally distributed military force.

A Tobacco-Free Medical Campus Policy is Associated With Decreased Secondhand Smoke Exposure and Increased Satisfaction Among Military Medical Employees: Results of a Mixed-Methods Evaluation.

INTRODUCTION: Tobacco control is an ongoing concern for the U.S. Army. Although tobacco use is currently prohibited within all military hospitals and clinics, known as military treatment facilities (MTFs), no such facility had implemented a tobacco-free medical campus (TFMC) policy before 2012. This evaluation examined the effects of one Army installation's TFMC policy implementation at its medical facilities. MATERIALS AND METHODS: Online questionnaires were distributed to medical campus employees, including Active Duty Soldiers, civilians, and contractors, before policy implementation (N = 1,210) and 12 months following policy implementation (N = 1,147). Chi-square analyses, independent t tests, and logistic regression models were utilized to examine pretest/post-test changes in employees' secondhand smoke (SHS) exposure; tobacco use, motivation to quit, and cessation; and health outcomes. Twenty-three focus groups, interviews, and informal discussions with 65 employees and patients were conducted 13 months after initial policy implementation to capture both the intended and unintended policy effects. RESULTS: After controlling for demographic characteristics, the study found that employees had more than twice the odds of exposure to SHS in the workplace at baseline than at 12-month follow-up (odds ratio: 2.06, 95% confidence interval: 1.73-2.46, p < 0.001). Employees also reported a lower prevalence of diagnosis with chronic bronchitis (p < 0.05) at follow up compared to baseline. Although the mean number of sick days taken for respiratory illness decreased over time, results were not significant after controlling for demographic factors. No significant differences existed in tobacco-use prevalence or quit rates among tobacco users over time. Employees reported significantly higher levels of satisfaction with a TFMC policy than the original policy (p < 0.001) though this finding was moderated by smoker status such that smokers reported lower levels of satisfaction with the policy over time. Qualitative findings revealed that the most common policy effect was that the policy caused smokers to change the location of where they used tobacco to off campus. Findings further revealed several unintended policy effects, including safety concerns and greater visibility of smokers in front of the MTF. CONCLUSION: The first Army MTF TFMC policy was associated with reported reductions in SHS exposure and improvements in some short-term health outcomes. The policy had no observed association with tobacco-use prevalence, motivation to quit, or cessation at 12-month follow-up. Focus group participants discussed several positive and negative policy effects. These policies should be expanded and studied in more depth across military installations, and policy makers should plan mitigation strategies to reduce unintended effects. This is an important step in military tobacco control, but additional efforts will be necessary to curb tobacco use within this population.

Resource Dependent Effects During Sex Categorization.

The limited capacity of face perception resources in the left cerebral hemisphere was examined using a sex categorization task. One study tested the hypothesis that sex categorization is impeded whenever feature extraction resources in the left hemisphere are simultaneously being utilized by another task. This hypothesis was tested by presenting prime faces for either 32 ms or 320 ms to either the left or right visual-field just before centrally presented target faces were categorized by sex. Results showed that sex categorization was slower after prime faces were presented for 32 ms in the right visual-field compared to the left visual-field. This difference was not found after the 320 ms prime length. The results are interpreted in the context of a neurocognitive model of social perception and suggest that efficient sex categorization depends, in part, on the availability of facial feature extraction resources in the left hemisphere.
