There have been some observations to indicate that waiting for a shock is stressful, that the coining of an anticipated shock can serve as a tension reliever, and that failure to obtain an anticipated shock is more stressful than being shocked. Based on these observations, the following hypotheses were tested. If it is true that failure to receive shock is more stressful than the shock itself, it should be possible to train an animal to bring on a shock that had failed to come when anticipated. If a period of anticipating shock is stressful, and shock serves as a reliever of the stress, it should be possible to train an animal to perform a response instrumental to bringing on the shock sooner. Results indicated that shock does seem to serve as a reliever, that waiting for shock is stressful, but that failure to receive an anticipated shock under these circumstances is not more stressful than the shock itself. In addition, it was found that subjects learned to produce shock instrumentally if the shock was inevitable and could thus be brought about sooner. Results were inconclusive, though generally negative, on the issue of whether S’s would produce an avoidable shock that had failed to come when anticipated.  相似文献

We evaluated the usefulness of 2 assessments to guide treatment selection for individuals whose prior functional analysis indicated that automatic reinforcement maintained their problem behavior. In the 1st assessment, we compared levels of problem behavior during a noncontingent play condition and an alone or ignore condition. In the 2nd, we assessed participants’ relative preferences for automatic reinforcement and social reinforcers in a concurrent‐operants arrangement. We used the results of these 2 assessments to assign 5 participants to a treatment based on noncontingent access to social reinforcers or to a treatment based on differential access to social reinforcers. We conducted monthly probes with the participants over 10 to 12 months to evaluate the effects of the treatment procedures. All participants showed reductions in problem behavior over this period.  相似文献

We investigated the association between cultural worldviews and climate change risk perceptions, support for climate friendly policies and climate change mitigation behaviours in a large Chinese sample. Items from Dake's cultural theory scales and Kahan's cultural cognition scale were presented to a Qualtrics online panel consisting of 515 Mandarin‐speaking residents of Beijing. A series of factor analyses revealed that the combined item sets were best represented by four‐dimensions: hierarchism, individualism, egalitarianism and fatalism. Mediation analysis revealed that respondents with egalitarian and non‐fatalist worldviews perceived greater risk associated with climate change, which in turn predicted greater support for policies to manage climate change and increased mitigation behaviour. In addition, respondents who scored high on individualism were less likely to support climate change policies, but this effect was not mediated by risk perceptions. Overall, our results suggest cultural worldviews may influence policy support both directly and indirectly through risk perceptions.  相似文献

In an assessment of the Alcohol Myopia Theory (AMT), the effects of alcohol on an eyewitness's recall of high‐salience and low‐salience details were investigated. In a laboratory, Study 1 participants watched a staged videoed theft whilst either sober (control or placebo), above (MBAC = 0.09%) or below (MBAC = 0.06%) the UK drink‐drive limit. A week later, a free recall and recognition tests were completed. Intoxication was not found to reduce recall accuracy using either recall task. In Study 2, whilst on a night out, participants watched the videoed theft with high (MBAC = 0.14%) or low (MBAC = 0.05%) blood alcohol concentrations (BACs). A week later, the free recall and recognition tests were attempted. High BACs were seen to impair recall when memory was assessed through free recall but not with the recognition test. Neither study found the attention narrowing predicted by AMT using either recall technique, although poor recall for low‐salience details in all groups may have contributed to this result.

We follow Bender et al.’s (Religion on the Edge: De‐Centering and Recentering the Sociology of Religion) call to study religion “on the edge” by looking at the work of chaplains, religious professionals who work outside of congregations. Rather than studying chaplains within a single type of institution—the military, healthcare, or other sectors—we shift the unit of analysis to geography, asking where chaplains in Greater Boston worked between 1945 and the present. Based on coverage in the Boston Globe, we find that chaplains, mostly men, worked across Greater Boston between 1945 and 2015. The majority were Catholic with frequent minorities of Protestants and Jews, and—after 1995—a few Buddhists, Muslims, and Humanists. Most worked in higher education, healthcare, and prisons. While much of the chaplains’ work seems improvisational and varied, we identify services related to ceremonies, bearing witness, and working around death as common occurrences across the venues where chaplains worked. To the extent that these patterns are evident in other cities, they suggest that chaplains have regularly been a quiet part of the religious landscape, that they are a consistent part of the institutional field, and that their work has more commonalities across sectors than previous studies suggest.  相似文献

Research on cumulative risk is growing, however, little work has occurred in low- or middle-income countries, and few studies have focused on processes linking risk to outcomes. This study explored relations between components of cumulative risk and adjustment in a sample of 324 South African youth (M age?=?13.11 years; SD?=?1.54 years; 65% female; 56% Black/African; 14% Colored; 23% Indian; 7% White), and tested competing models of emotion dysregulation as a mediator or moderator of risk—adjustment links. Data was collected from youth and their female caregivers during home interviews. Structural equation models and regression analyses accounting for age and sex contributions revealed that emotion dysregulation mediated associations between sociodemographic risk and internalizing symptoms, externalizing problem behavior, and drug use severity, and moderated links between psychosocial risk and internalizing symptoms and externalizing problem behavior. For the mediator models, sociodemographic risk was associated with impaired emotion regulation, which in turn was linked with heightened adjustment difficulties. For the moderator models, psychosocial risk was linked with adjustment problems only when emotion dysregulation was high. These data indicate the importance of disentangling components of cumulative risk. Future research within the South African cultural context might build on these findings by adapting and testing school- or family-based prevention or intervention programs that include modules on emotion regulation.  相似文献

Objective: This study investigates the impact of HIV diagnosis on subjective social status and if changes are linked to health outcomes.

Design: Two measures of subjective social status, socio-economic and standing in the community were examined in 342 Australian HIV-positive gay men in 2014. Participants recalled ratings at diagnosis were compared with current ratings.

Main outcome measures: Self-reported mental (psychological distress, self-esteem, positive mental health and satisfaction with life) and physical health (self-rated health, CD4 count, viral load).

Results: Half of the participants reported improvements in subjective socio-economic status (59%) or standing in the community (52%) since diagnosis, yet one quarter reported socio-economic status (25%) or standing in the community had decreased (23%). Increases in either measure of subjective social status were linked to higher self-esteem, positive mental health, satisfaction with life and better self-rated health. Decreases in subjective social status, however, were strongly linked to poorer outcomes on all mental health measures. Decreases in standing in the community were also associated with poorer physical self-rated health.

Conclusion: Most participants reported their subjective social status were the same or better since diagnosis. Changes in subjective social status following diagnosis were strongly linked to mental health outcomes. Those who reported a decrease in subjective social status were particularly vulnerable to mental health problems.  相似文献
