We examine a distinctive kind of problem for decision theory, involving what we call discontinuity at infinity. Roughly, it arises when an infinite sequence of choices, each apparently sanctioned by plausible principles, converges to a ‘limit choice’ whose utility is much lower than the limit approached by the utilities of the choices in the sequence. We give examples of this phenomenon, focusing on Arntzenius et al.’s Satan’s apple, and give a general characterization of it. In these examples, repeated dominance reasoning (a paradigm of rationality) apparently gives rise to a situation closely analogous to having intransitive preferences (a paradigm of irrationality). Indeed, the agents in these examples are vulnerable to a money pump set-up despite having preferences that exhibit no obvious defect of rationality. We explore several putative solutions to such problems, particularly those that appeal to binding and to deliberative dynamics. We consider the prospects for these solutions, concluding that if they fail, the examples show that money pump arguments are invalid. 相似文献

Motivational approaches to depression emphasize the role of dysfunctional motivational dynamics, particularly diminished reward and incentive processes associated with anhedonia. A study examined how anhedonic depressive symptoms, measured continuously across a wide range of severity, influenced the physiological mobilization of effort during a cognitive task. Using motivational intensity theory as a guide, we expected that the diminished incentive value associated with anhedonic depressive symptoms would reduce effort during a “do your best” challenge (also known as an unfixed or self-paced challenge), in which effort is a function of the value of achieving the task’s goal. Using impedance cardiography, two cardiac autonomic responses were assessed: pre-ejection period (PEP), a measure of sympathetic activity and our primary measure of interest, and respiratory sinus arrhythmia (RSA), a measure of parasympathetic activity. As expected, PEP slowed from baseline to task as anhedonic depressive symptoms increased (as measured with the Depression Anxiety Stress Scale), indicating diminished effort-related sympathetic activity. No significant effects appeared for RSA. The findings support motivational intensity theory as a translational model of effort processes in depression and clarify some inconsistent effects of depressive symptoms on effort-related physiology found in past work. 相似文献

The current study examined dimensions of perfectionism, stress, hopelessness, and suicidality in a sample of adolescent psychiatric patients diagnosed with depression. This study evaluated the unique contribution of perfectionism in predicting suicidality after considering other predictors (i.e., hopelessness, depression) and it also examined the diathesis-stress model of perfectionism and suicide. A sample of 55 adolescents (41 females, mean age = 15.53, 25.5 % ethnic/racial minorities) who were psychiatric patients completed measures including the Child-Adolescent Perfectionism Scale, subjective and objective indices of life stress, daily hassles, depression, hopelessness, suicide ideation, prior attempts and suicide potential. In addition, other informants (i.e., adolescents’ parents) completed a diagnostic interview and an interview assessing major stressful experiences. Socially prescribed perfectionism (i.e., the perception that others require perfection of oneself) predicted concurrent levels of suicide potential and this association with suicide potential held even after controlling for the variances accounted for by depression and hopelessness. Hierarchical regression analyses provided partial support for the diathesis-stress model, that is, socially prescribed perfectionism interacted with daily hassles to predict concurrent suicide potential even after controlling for depression, hopelessness, and prior suicide attempt. Together, these findings suggest that socially prescribed perfectionism acts as a vulnerability factor that is predictive of suicide potential or risk among clinically depressed adolescents. 相似文献

Two different types of ruminative coping, depressive rumination and grief rumination, negatively influence bereavement outcome. Although grief-specific rumination is likely to be relevant in the bereavement context no internationally validated scale to measure grief rumination exists. Therefore, the current contribution aims to validate the Utrecht Grief Rumination Scale (UGRS), a scale developed to measure grief-specific rumination, in an English sample. Psychometric properties of the English UGRS were compared with those in a Dutch sample. 204 British adults (89 % women, 11 % men), bereaved on average 16 months ago, and 316 Dutch adults (88 % women, 12 % men), bereaved on average 12 months ago, filled out online questionnaires. Different types of rumination (grief rumination, brooding, reflection, trait rumination) and symptoms of psychopathology (anxiety, depression, complicated grief) were measured. A correlated five factor model provided the best fit for the UGRS. Multi-group comparisons showed that the factor structures of the English and Dutch version of the UGRS were highly similar across language groups. The UGRS showed excellent reliability. Results further supported the construct, convergent, divergent and concurrent validity of the English UGRS. The psychometric properties of the Dutch UGRS corroborated these findings. The UGRS appears a valid instrument to assess grief-specific rumination in international research and may have potential applicability as a clinical instrument to assess rumination in individuals with problematic grief. 相似文献

Sustainable solutions to the access to mental health care problems are complex and must address both the availability of mental health care resources and the acceptability of those resources to consumers. The purpose of this study was to determine how to address the acceptability problem by learning from medical and mental health care providers what mental health therapists need to know to be successful in providing care in rural communities. Using a qualitative design, focus groups were conducted in three rural communities (<2,500) with medical and mental health care providers practicing in these communities. Data were analyzed using inductive qualitative methods. Results indicate that in addition to sound clinical skill, mental health therapists should (A) be sensitive to the culture of the rural community in which they are working and (B) practice in a way that accommodates to the care culture of the community. The latter includes spending time with patients commensurate with what is expected by other providers, engaging in generalist practice, and collaborating with local providers in patient care. An important implication of these results is that mental health care must be acceptable to both the residents of the community and the gatekeepers to health care. 相似文献

We examined the impact that measurement artifacts (antithetical items that overlap counterproductive work behavior (CWB), agreement response, halo in supervisor ratings) in organizational citizenship behavior (OCB) measures has on observed relationships between OCB and 15 predictors. Respondents were 146 employees and their supervisors who completed surveys that included OCB measures with and without artifacts. Predictors (conscientiousness, emotional stability, empathy, distributive justice, procedural justice, role ambiguity, role conflict, leader–member exchange, affective organizational commitment, job satisfaction, negative and positive emotion, turnover intention, CWB, and task performance) were chosen that related to OCB in prior meta-analyses. Results with the OCB scale with artifacts were consistent with meta-analyses, whereas results with the artifact-controlled OCB scale were not, suggesting that accepted conclusions about OCB’s relationships with many other variables should be reexamined. 相似文献

Background
Non-suicidal self-injury (NSSI) starts in adolescence and decreases during young adulthood. Despite a high prevalence among adolescents only a few therapeutic interventions directly addressing adolescents exist.Aim
By connecting music therapy with elements from behavioral therapy an attempt was made to create a therapeutic program which is attractive to adolescents.Material and methods
A pilot trial of the program “Stop cutting - rock!” was conducted with 12 adolescent females with a mean age of 15.15 years (standard deviation SD ±1.34). The study aimed to compare the frequency of NSSI throughout the treatment phase as well as a pre-post comparison of depression scores.Results
The results showed a trend towards a decreasing frequency of NSSI. Depression scores decreased significantly between the assessment before therapy and at a 3-month follow-up after the end of the therapy.Conclusion
The positive feedback concerning music therapeutic elements points to the attractiveness of the approach. By integrating multimodal therapeutic strategies it seems possible to create an individually tailored intervention for adolescents with NSSI. 相似文献999.

The current study examined interactive effects among personality and job stressors in predicting employees' engagement in counterproductive work behavior (CWB) defined as behavior that harms organizations or people in organizations. Survey data were collected from 932 employees and results showed significant negative relationships of agreeableness, conscientiousness, and emotional stability with CWB directed at organizations (CWB‐O) and people (CWB‐P), and significant positive relationships of interpersonal conflict and organizational constraints with CWB‐O and CWB‐P. Further, it was found that the positive relationships of interpersonal conflict with CWB‐O and CWB‐P were strongest for people of low emotional stability–low agreeableness among all emotional stability–agreeableness combinations, and that the positive relationships of organizational constraints with CWB‐O and CWB‐P were strongest for people of high emotional stability–low conscientiousness among all emotional stability–conscientiousness combinations. 相似文献
