Resident-generated versus instructor-generated cases in ethics and professionalism training

Background  

The emphasis on ethics and professionalism in medical education continues to increase. Indeed, in the United States the ACGME will require residency programs to include professionalism training in all curricula by 2007. Most courses focus on cases generated by the course instructors rather than on cases generated by the trainees. To date, however, there has been no assessment of the utility of these two case discussion formats. In order to determine the utility of instructor-generated cases (IGCs) versus resident-generated cases (RGCs) in ethics and professionalism training, the author developed an innovative course that included both case formats. The IGCs were landmark cases and cases from the experience of the course instructors, while the RGCs were selected by the residents themselves. Residents were then surveyed to assess the strengths and weaknesses of each format.     

Stressing the group: social identity and the unfolding dynamics of responses to stress

Participants in the British Broadcasting Corporation (BBC) prison study were randomly assigned to high-status (guard) and low-status (prisoner) groups. Structural interventions increased the prisoners' sense of shared group identity and their willingness to challenge the power of the guards. Psychometric, physiological, behavioral, and observational data support the hypothesis that identity-based processes also affected participants' experience of stress. As prisoners' sense of shared identity increased, they provided each other with more social support and effectively resisted the adverse effects of situational stressors. As guards' sense of shared identity declined, they provided each other with less support and succumbed to stressors. Findings support an integrated social identity model of stress that addresses intragroup and intergroup dynamics of the stress process.     

A first examination of the relationships between primed subconscious goals, assigned conscious goals, and task performance

The authors conducted 2 studies of subconscious goal motivation. First, the authors ran a pilot study to establish the effects of priming of subconscious goals on a performance task frequently used in goal setting research. Second, the authors conducted the main study in which the authors examined the effects of both priming of subconscious goals and assigned conscious goals on the same performance task. The authors found significant main effects of both manipulations and a significant interaction between subconscious and conscious goals. The effects of conscious difficult and do-best goals were enhanced by subconscious goals, although conscious easy goals were not affected. All effects from the main study still held after 1 day.     

Three-month-olds' visual preference for faces and its underlying visual processing mechanisms

This study was aimed at investigating the face preference phenomenon and its underlying mechanisms at 3 months of age. Using an eye-tracker apparatus, Experiment 1 demonstrated that 3-month-olds prefer natural face images to unnatural ones, replicating and extending previous evidence obtained with schematic facelike stimuli. Experiments 2 and 3 showed that the general mechanisms that induce face preference in newborns could not explain the same phenomenon at 3 months of age, when infants are attracted by perceptual cues more specific to faces. This suggests that signs of a process of cognitive specialization are already present in 3-month-olds' visual behavior toward faces.     

A chimpanzee (Pan troglodytes) analogue of cross-national generalization of personality structure: zoological parks and an African sanctuary

Six personality factors, including five resembling the human Big Five, had previously been identified in a separate group of zoo-housed chimpanzees. Comparability of chimpanzee personality factor structure was examined in two highly contrasting habitats: zoos and a large African sanctuary. Questionnaires for the zoo chimpanzees were in English, while most for the chimpanzees in the sanctuary were in French. Differences between the two settings were sufficiently extensive to make them analogous to cross-national human personality studies. Internal consistencies for five of the six factors did not differ between the two samples. The patterns of correlations between the unit-weighted factors were also similar for the two samples. Data from these two samples were pooled and factor analyzed. The resulting factor structure was then rotated to the factor structure described in the original study of chimpanzee personality. Dominance, Extraversion, Dependability, and Agreeableness had high congruences. Emotionality and Openness did not, but the items that had the highest loadings were consistent with the factors' definitions. Finally, sex and age effects for all factors generalized across habitats.     

Effect of color schemes and environmental sensitivity on job satisfaction and perceived performance

Effects of interior office color and individual stimulus screening ability, i.e. instinctive perceptual filtering of irrelevant stimuli, on perceived performance and job satisfaction were examined on various outcome measures over a 4-day work week in a laboratory setting. Workers performed specific tasks and worked regular hours for 4 consecutive days in the same office. They were separated into three groups according to their ability to ignore irrelevant stimuli in the interior space. Those in the white and predominantly blue-green offices reported higher perceived job performance and satisfaction than those in the predominantly red office regardless of stimulus screening ability. Workers with high to moderate stimulus screening ability indicated greater perceived performance and job satisfaction than did workers with low stimulus screening ability. Results for color schemes are discussed in terms of preference and social expectations.     

Family Support and Mental Health in Pregnant Women Experiencing Interpersonal Partner Violence: An Analysis of Ethnic Differences

This study investigated the relationship between family support and mental health in a community sample of pregnant women experiencing interpersonal partner violence (IPV). This study also examined how family support may differentially affect mental health in Black and White women experiencing IPV. A total of 110 participants (32 Black and 78 White) were obtained from the first time period of a longitudinal study examining the effects of domestic violence on women. The model was supported (χ² = 142.55; df = 72, p > .001, RMSEA = .07). Black women had better mental health than White women. However, ethnicity was not a significant predictor of family support. Implications from this study highlight the need for further research on the role of family support in the lives of physically abused women as well as the need to incorporate cross cultural perspectives when examining this issue.     

Colour, polarity, disparity, and texture contributions to motion segregation

We measured how different cues are combined in motion-segregation processes by using motion stimuli where randomly distributed target dots were organised in global revolving motion while the remaining noise dots performed random motion. Target dots were cued with a different colour, polarity, disparity depth, or texture orientation than the noise dots, or they were the same as the noise dots. The stimuli were presented with a prolonged static cue preview which provided position cues to target dots or, briefly with static pre-target and post-target noise frames, which provided false position cues (no preview). All cues efficiently facilitated global motion segregation in cued-preview conditions. Colour completely failed to facilitate global motion segregation in no-preview conditions. Polarity and disparity facilitated segregation in no-preview conditions, although sensitivities were lower than in the preview conditions. Remarkably, texture orientation largely facilitated motion segregation by the same amount in both cued-preview and no-preview conditions. So, colour provides only position cues to the motion-segregation task whereas texture orientation, disparity, and to a lesser extent polarity are integrated with the segregation process.
