Despite widespread use of mental health testimony in cases where violence risk is at issue, relatively little is known about the impact of such information on juror decision-making. This study addressed the effects of testimony based on three types of risk assessment instrument or method (clinical opinion, actuarial assessment, and ratings of psychopathy) to examine whether they would have differential impact on jurors' perceptions of the defendant. In a mock sexually violent predator civil commitment trial, 172 undergraduates were presented a case summary that included prosecution and defense expert testimony related to violence risk based on one of the three methods noted above. Consistent with earlier research, the hypothesis that a defendant described as a "high risk psychopath" by the prosecution would be judged more severely than a defendant judged as "high risk" based on other evaluation procedures was supported, but only among female jurors. Unlike prior studies, little support was found for the hypothesis that clinical opinion testimony would be more influential than actuarially based testimony for either gender. Mechanisms that may underlie the observed gender differences are discussed, as are the potential implications of these findings for civil commitment proceedings. 相似文献

The goal of the present studies was to construct and validate a short form of the 50-item Smoking Consequences Questionnaire (SCQ; T.H. Brandon & T. B. Baker, 1991), a measure of smoking outcome expectancies. In Study 1, a 21-item short form (S-SCQ) was derived from a sample of 107 young adults previously treated for substance abuse. In Study 2, the measure was cross-validated on 125 adolescents in treatment for substance abuse. Confirmatory factor analyses revealed good model fit and factorial invariance for the 4 S-SCQ subscales across both samples. Validation analyses on each sample found that subscale scores generally correlated significantly with smoking-related variables. The present studies provide initial evidence for the utility of the S-SCQ when used with young adults and adolescents. 相似文献

Spatial diagram representations such as hierarchies, matrices, and networks are important tools for thinking. Our data suggest that college students possess abstract schemas for these representations that include at least rudimentary information about their applicability conditions. In Experiment 1, subjects were better able to select the appropriate spatial diagram representation for a problem when cued to use general category information in memory about those representations than when cued to use specific example problems given during the experiment. The results of Experiment 2 showed that the superior performance in the general category condition was not based on a comparison of the test problems with examples in memory. The results of Experiment 3 showed that the superior performance was not due to learning that occurred during the experiment or to transfer appropriate processing. The General Discussion section considers the nature of students' representation schemas and the question of why college students have only rudimentary schemas for common and widely applicable diagrammatic representations. 相似文献

The experience of mixed emotions increases with age. Socioemotional selectivity theory suggests that mixed emotions are associated with shifting time horizons. Theoretically, perceived constraints on future time increase appreciation for life, which, in turn, elicits positive emotions such as happiness. Yet, the very same temporal constraints heighten awareness that these positive experiences come to an end, thus yielding mixed emotional states. In 2 studies, the authors examined the link between the awareness of anticipated endings and mixed emotional experience. In Study 1, participants repeatedly imagined being in a meaningful location. Participants in the experimental condition imagined being in the meaningful location for the final time. Only participants who imagined "last times" at meaningful locations experienced more mixed emotions. In Study 2, college seniors reported their emotions on graduation day. Mixed emotions were higher when participants were reminded of the ending that they were experiencing. Findings suggest that poignancy is an emotional experience associated with meaningful endings. 相似文献

Child‐directed teaching and social learning at 18 months of age: evidence from Yucatec Mayan and US infants 下载免费PDF全文
In several previous studies, 18‐month‐old infants who were directly addressed demonstrated more robust imitative behaviors than infants who simply observed another's actions, leading theorists to suggest that child‐directed interactions carried unique informational value. However, these data came exclusively from cultural communities where direct teaching is commonplace, raising the possibility that the findings reflect regularities in infants' social experiences rather than responses to innate or a priori learning mechanisms. The current studies consider infants' imitative learning from child‐directed teaching and observed interaction in two cultural communities, a Yucatec Mayan village where infants have been described as experiencing relatively limited direct instruction (Study 1) and a US city where infants are regularly directly engaged (Study 2). Eighteen‐month‐old infants from each community participated in a within‐subjects study design where they were directly taught to use novel objects on one day and observed actors using different objects on another day. Mayan infants showed relative increases in imitative behaviors on their second visit to the lab as compared to their first visit, but there was no effect of condition. US infants showed no difference in imitative behavior in the child‐directed vs. observed conditions; however, infants who were directly addressed on their first visit showed significantly higher overall imitation rates than infants who observed on their first visit. Together, these findings call into question the idea that child‐directed teaching holds automatic or universal informational value. 相似文献

Abstract Two studies examined the association of gender and occupational group (nursing versus non-nursing) with perceived risk of abuse (sexual harassment and verbal and physical abuse) as well as the relationship of perceived abuse risk with burnout and sense of community. Study 1, comprising of two settings (tertiary care hospital, N = 3,062; psychiatric hospital, N = 383), found gender and occupational group associated with perceived risk of abuse (women felt greater risk than men; nurses felt greater risk than non-nurses). It also found a gender/occupational group interaction. Study 2, conducted at an Irish tertiary care hospital (N = 892), found nurses felt at greater risk for all three types of abuse than did non-nurses. Further, women perceived themselves at greater risk for sexual harassment and verbal abuse than did men; the study found no gender difference regarding physical abuse. The analysis identified a gender/occupational group interaction for sexual harassment. The study considers methods of reducing perceived risk in regard to the research literature on abuse at work. 相似文献

What's parenting got to do with it: emotional autonomy and brain and behavioral responses to emotional conflict in children and adolescents 下载免费PDF全文

Healthy parenting may be protective against the development of emotional psychopathology, particularly for children reared in stressful environments. Little is known, however, about the brain and behavioral mechanisms underlying this association, particularly during childhood and adolescence, when emotional disorders frequently emerge. Here, we demonstrate that psychological control, a parenting strategy known to limit socioemotional development in children, is associated with altered brain and behavioral responses to emotional conflict in 27 at‐risk (urban, lower income) youth, ages 9–16. In particular, youth reporting higher parental psychological control demonstrated lower activity in the left anterior insula, a brain area involved in emotion conflict processing, and submitted faster but less accurate behavioral responses—possibly reflecting an avoidant pattern. Effects were not replicated for parental care, and did not generalize to an analogous nonemotional conflict task. We also find evidence that behavioral responses to emotional conflict bridge the previously reported link between parental overcontrol and anxiety in children. Effects of psychological control may reflect a parenting style that limits opportunities to practice self‐regulation when faced with emotionally charged situations. Results support the notion that parenting strategies that facilitate appropriate amounts of socioemotional competence and autonomy in children may be protective against social and emotional difficulties. 相似文献

In this study we explored the views of Mental Health professionals and general practitioners (GPs) regarding spiritual care and the effect of personal and cultural background on their views. Data were collected through anonymous questionnaires posted to hospital nursing and medical staff at Hollins Park Hospital, Warrington, UK, and to all GPs within the hospital catchments area. Forty-five percent of GPs, 33% of psychiatrists, and 76% of nursing staff (p < 0.05) felt strongly that human beings are made up of spirit as well as body. More nurses felt that spiritual care is equally as important as other forms of care (52%) compared with psychiatrists (33%) and GPs (29%). A higher percentage of nursing than medical staff had previous training in this area and were more likely than medical staff to consider themselves appropriate to give spiritual advice. A total of 20% of GPs and 33% of psychiatric staff stated the need for training in this area and GPs especially felt they lacked time. Professionals’ views are influenced by cultural and religious backgrounds, with significantly more non-UK born respondents feeling strongly that human beings all have a spiritual component. Many doctors do not consider spiritual care has a role for them to be involved in and many feel too pressured in daily life to take this on. Nurses are more inclined to take a holistic approach to care in this respect. Some people with mental health problems have spiritual care needs and we should be aware of this as an important facet to therapy. 相似文献
