The "face in the crowd effect" refers to the finding that threatening or angry faces are detected more efficiently among a crowd of distractor faces than happy or nonthreatening faces. Work establishing this effect has primarily utilized schematic stimuli and efforts to extend the effect to real faces have yielded inconsistent results. The failure to consistently translate the effect from schematic to human faces raises questions about its ecological validity. The present study assessed the face in the crowd effect using a visual search paradigm that placed veridical faces, verified to exemplify prototypical emotional expressions, within heterogeneous crowds. Results confirmed that angry faces were found more quickly and accurately than happy expressions in crowds of both neutral and emotional distractors. These results are the first to extend the face in the crowd effect beyond homogenous crowds to more ecologically valid conditions and thus provide compelling evidence for its legitimacy as a naturalistic phenomenon.
A voluntary hospitalist service at a community-based teaching hospital produced reductions in length of stay and costs that became statistically significant in the second year of use. A mortality benefit extending beyond hospitalization was noted in both years. Future investigations are needed to understand the ways in which hospitalists increase clinical efficiency and appear to improve the quality of care.
To assess the ability of food frequency methods to measure current dietary calcium intake in elderly women, the authors administered two types of food frequency instruments to 37 randomly selected women who attended two senior citizens centers in San Francisco, and they compared those responses to seven-day food records. A 34-item food frequency instrument (with portion sizes rated as small, medium, or large) correlated well (r = 0.76) with the estimated calcium intake from seven-day records. Limiting the instrument to the top 15, 10, or five foods that contribute to dietary calcium intake had little effect on this correlation (r = 076, 0.75, and 0.67, respectively). Rating all portions as "medium" reduced these correlations somewhat. An 18-item instrument, which asks respondents to rate portion sizes in ounces or cups, did not correlate as well with the seven-day records (r = 0.49). The authors conclude that brief food frequency instruments which rate portion sizes on a simple qualitative scale may be suitable for many clinical uses and adequate for some types of epidemiologic studies of calcium intake in elderly women.
Background The expectation for graduate medical education programs to ensure that trainees are progressing toward competence for unsupervised practice prompted requirements for a committee to make decisions regarding residents' progress, termed a clinical competency committee (CCC). The literature on the composition of these committees and how they share information and render decisions can inform the work of CCCs by highlighting vulnerabilities and best practices.
Interprofessional team care by learners was effective in improving quality of care for adult patients with diabetes treated in general medicine clinics. The chronic illness framework resulted in more appropriate health care utilization.
Institutions orient resident performance review toward problem identification; a developmental approach is uncommon. Clarifying the purpose of resident performance review and employing efficient information systems that synthesize performance data and engage residents and faculty in purposeful feedback discussions could enable the meaningful implementation of milestones-based assessment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
