General activity subsequent to reward (R) and nonreward (N) was monitored at 5-sec intervals with a stabilimeter in the runway goal box. Activity of never-rewarded control Ss was also measured. In Expt 1 it was found that the frustration effect (difference between N- and R-trial activities) disappeared after about 40 sec of goal box confinement. This disappearance of the frustration effect was due to activity increase on R trials rather than activity decrease on N trials as a function of time. Comparison of N-trial activity with control group activity indicated that frustration does not dissipate within 60 sec. Expt 2 investigated activity following reward and nonreward as a function of reward magnitude. Evidence from these experiments suggests that the late R-trial activity increase results from frustration, possibly conditioned to apparatus cues on N trials. 相似文献

The reply to the commentaries discusses the challenges of treating sexual disgust from the perspective of comparative-integrative psychoanalysis. My paper tried to weave in the oedipal, the adaptationist perspective of research on disgust by evolutionary developmental psychologists, and the psychoeducational into more standard psychoanalytic ways of thinking about and working with sexual disgust that tend to neglect those viewpoints. How does one bring in a fresh perspective without throwing out the baby with the bathwater? 相似文献

Disaster recovery work increases risk for mental health problems, yet the mechanisms underlying this association are unclear. We explored links from recovery work to post‐traumatic stress (PTS), major depression (MD), and generalized anxiety disorder (GAD) symptoms through physical health symptoms and household income in the aftermath of the Deepwater Horizon oil spill. As part of the NIEHS GuLF STUDY, participants (N = 10,141) reported on cleanup work activities, spill‐related physical health symptoms, and household income at baseline, and mental health symptoms an average of 14.69 weeks (SD = 16.79) thereafter. Cleanup work participation was associated with higher physical health symptoms, which in turn were associated with higher PTS, MD, and GAD symptoms. Similar pattern of results were found in models including workers only and investigating the influence of longer work duration and higher work‐related oil exposure on mental health symptoms. In addition, longer worker duration and higher work‐related oil exposure were associated with higher household income, which in turn was associated with lower MD and GAD symptoms. These findings suggest that physical health symptoms contribute to workers’ risk for mental health symptoms, while higher household income, potentially from more extensive work, might mitigate risk. 相似文献

Data for 422 methadone treatment clients in the National Treatment Improvement Evaluation Study (NTIES) were analyzed. Clients maintained continuously in methadone treatment for longer than 12 months and clients who leftbetween 3–12 months were compared with clients treated for less than 3 months. Additionally, clients treated for 3–12 months who had short follow-up periods (6-month average) were compared with 3–12-month clients with long follow-up periods (11-month average). Positive treatment outcomes includinglower drug use, reduced risk of viral infectionand sexually transmitted disease (through needle sharing and multiple sex partners), and less criminality wereassociated with both longer duration treatment and shorter follow-up periods. The findings suggested that continuous methadone treatment of 12 or more months is optimal, whereas stays of less than3 months may be ineffective. Furthermore, stays of 3–12 months are likelyto be beneficial over a relatively short time span, for example 6 months. 相似文献

Recent advances in theory and research on the relations among mental simulation, affect, and personality are summarized and combined. Research has shown that (a) affect and mental simulations can influence each other, (b) mental simulations can serve diverse self-motives, and (c) personality characteristics are related to divergent functions of mental simulations. Findings in these three areas are synthesized into a conceptual framework on the basis of three attributes of mental simulations: (a) time, whether simulations are prospective or retrospective; (b) direction, whether simulations are upward or downward; and (c) focus, whether simulations are contrasted or assimilated. This integrated framework not only may enable a greater understanding of existing findings, but also suggests novel and unique predictions for future research on understanding personality processes, automaticity in simulations, and coping with life events. 相似文献
