To determine if choroidal melanoma patients want cytogenetic prognostic information. Ninety-nine choroidal melanoma patients completed a questionnaire regarding their opinions about receiving prognostic information. The perceived usefulness of prognostic information was evaluated in patients who had undergone cytogenetic testing. Depressive symptoms, quality of life, and interest in supportive counseling during test receipt were assessed. Ninety-seven percent of respondents reported that they would have wanted prognostic information at the time of their treatment and 98% of respondents reported that supportive counseling should be offered when prognostic information is given. Patients who had received a more favorable prognostic result were more likely to endorse the usefulness of cytogenetic testing than were patients who had received a less favorable prognostic result. Psychological status did not vary significantly as a function of cytogenetic test result. Prognostic information was important to patients with choroidal melanoma, even in the absence of prophylactic measures which might improve prognosis.  相似文献

The accuracy of first impressions was examined by investigating judged construct (negative affect, positive affect, the Big five personality variables, intelligence), exposure time (5, 20, 45, 60, and 300 s), and slice location (beginning, middle, end). Three hundred and thirty four judges rated 30 targets. Accuracy was defined as the correlation between a judge’s ratings and the target’s criterion scores on the same construct. Negative affect, extraversion, conscientiousness, and intelligence were judged moderately well after 5-s exposures; however, positive affect, neuroticism, openness, and agreeableness required more exposure time to achieve similar levels of accuracy. Overall, accuracy increased with exposure time, judgments based on later segments of the 5-min interactions were more accurate, and 60 s yielded the optimal ratio between accuracy and slice length. Results suggest that accuracy of first impressions depends on the type of judgment made, amount of exposure, and temporal location of the slice of judged social behavior.  相似文献

What does it mean to have empathy within a late capitalist world? What does it mean to practise solidarity in a time of common sense individualism? In this piece, I reflect upon the deeply tragic case of Jean Charles de Menezes, a Brazilian immigrant who was brutally murdered by the British police in the wake of the London bombing. Drawing upon concepts from psychoanalysis and critical psychology, I discuss the affective and emotive nature of the case. I argue that the case offers insight into the irrational nature of `terror' used to explain state-led violence in a time of mass Islamophobic paranoia. I further argue that the emotive nature of the political is consistently disavowed in order to consolidate the face of the nation state as a white, western, masculinist, rational one. Finally, I offer thoughts on what this case might tell us about the interrelationship between discourses of `race,' racism, and citizenship within our contemporary political moment. Rather than being used to support succinct political and theoretical categories of identity politics, the death of Jean Charles de Menezes is an example of the urgent necessity for solidarity to be formed between marginalized bodies. The persistence of state-led murders, justified and legislated by the newest `N word' of the decade – `terrorist' – requires theoretical endeavours that transcend disciplinary boundaries and political action that transcends bodies.  相似文献

Previous studies have shown that people develop expectations about the taste and effects of consumed substances and that those expectations can guide future behavior, cognitions, and affect. Identifying expectancies for the taste of both low- and high-fat foods is important in determining people's reactions to changes in their diets. Study 1 was designed to determine the existence of expectancies for the taste of low-and high-fat foods and the effects of these expectations on food consumption and preference. Ninety-seven subjects tasted a bowl of ice cream and rated the taste on taste judgment forms. The fat content of the ice cream (high- versus low-fat) and the expectancy of high- versus low-fat content were independently manipulated using a balanced placebo design. Expectancy affected the consumption of ice cream under most circumstances: For women who received high-fat ice cream and for men, regardless of the ice cream received, consumption was higher when high-fat ice cream was expected than when low-fat ice cream was expected. Study 2 was designed to investigate the effects of educating individuals about the diet-cancer link on consumption and preference. Receiving information about diet and cancer, especially when the information was personalized, decreased overall consumption and reported preference. Current levels of daily fat consumption also affected laboratory consumption and preference. This study has several implications for interventions to lower dietary fat.  相似文献

Adolescence is a critical developmental period marked by an increase in risk behaviors, including nonsuicidal self‐injury (NSSI). Heightened reward‐related brain activation and relatively limited recruitment of prefrontal regions contribute to the initiation of risky behaviors in adolescence. However, neural reward processing has not been examined among adolescents who are at risk for future engagement for NSSI specifically, but who have yet to actually engage in this behavior. In the current fMRI study (N = 71), we hypothesized that altered reward processing would be associated with adolescents' thoughts of NSSI. Results showed that NSSI youth exhibited heightened activation in the bilateral putamen in response to a monetary reward. This pattern of findings suggests that heightened neural sensitivity to reward is associated with thoughts of NSSI in early adolescence. Implications for prevention are discussed.  相似文献

This study investigated hope as a mediator between children’s bullying involvement and emotional difficulties in a sample of 1,060 school‐age children (Grades 3–6). Results from structural equation modeling suggested that victimization leads to emotional difficulties both directly and indirectly through hope. Perpetration was indirectly associated with emotional difficulties. Findings highlight the role of children’s cognitive‐motivational process for emotional well‐being in response to bullying involvement. Implications for counseling interventions are discussed.  相似文献

Temporal structure reveals the potential adaptive strategies employed during upper extremity movements. The authors compared the temporal structure of upper extremity joints under 3 different reaching conditions: preferred speed, fast speed, and reaching with rhythmic auditory cues in 10 individuals poststroke. They also investigated the temporal structure of these 3 reaching conditions in 8 healthy controls to aid in the interpretation of the observed patterns in the poststroke cohort. Approximate entropy (ApEn) was used to measure the temporal structure of the upper extremity joints. ApEn was similar between conditions in controls. After stroke, ApEn was significantly higher for shoulder, elbow, and wrist both at fast speed and with rhythmic cues compared with preferred speed. ApEn at index finger was significantly higher only with rhythmic cues compared with preferred speed. The authors propose that practice reaching at faster speed and with rhythmic cues as a component of rehabilitation interventions may enhance adaptability after stroke.  相似文献

Parent ratings of ADHD and ODD symptoms depicted in written vignettes were examined for negative halo effects. Participants were 82 parents of children ages 6–12. Both unidirectional and bidirectional halo effects were found but to a lesser extent than in similar studies with teacher and college student raters. Specifically, parents were more likely to: (a) rate a child as inattentive in the presence of hyperactivity symptoms; (b) more likely to rate a child as oppositional in the presence of inattention and hyperactivity symptoms; and (c) more likely to rate a child as inattentive and hyperactive in the presence of oppositionality symptoms. Several specific symptoms were also found to be particularly susceptible to halo effects. Results suggest that parents may be more discerning raters of disruptive behavior disorders than teachers or college students and less prone to negative halo effects. Implications for clinical practice and future research directions are discussed.  相似文献
