Stereotypical behavior maintained by automatic reinforcement often does not result in harm but may be undesirable in some situations. In the current investigation, participants were 2 individuals who engaged in nonharmful stereotypical responses shown in an analogue functional analysis to be insensitive to social contingencies. After bringing these responses under stimulus control using differential punishment, both participants learned a mand to terminate punishment for stereotypy. We also assessed whether the mand could be brought under stimulus control.  相似文献

ABSTRACT One hundred twenty‐five astronaut autobiographies, interviews, and oral histories were content analyzed and scored for references to values ( Schwartz, 1992 ). The current study extended methods tested in 2 pilot studies of space veterans from many nations, of both sexes, and with different experiences within the history of human spaceflight. Value references reflected a high degree of concern with individualism, with Achievement, Enjoyment, and Self‐direction ranked highest. There were relatively few value differences across demographic categories, demonstrating the impact of the spaceflight experience. After returning, the astronauts showed increased concern with Universalism, Spirituality, and Power (social recognition), a broadened set of references to values oriented toward the collective good.  相似文献

Authors explored whether the dose-response relationship evident in PTSD also applied to cases of vicarious trauma and, if so, which variables serve to moderate such reactions. This study examined the surveyed responses of emergency care workers in a group geographically near the September 11, 2001 New York terrorist site, comparing the results to a group of emergency care workers geographically distant from the terrorist site. Study results lend support to the presence of a dose-response relationship within vicarious traumatization. Specific variables associated with higher distress levels for practitioners included the discipline of the practitioner, treating an injured victim, and personally knowing a victim of the New York terrorist attacks. Past training related to vicarious traumatization was not associated with lower distress levels for practitioners. In addition, practitioners' awareness and interest in psychological issues related to trauma appear to have been enhanced by geographic proximity to the New York terrorist attacks.  相似文献

Many healthcare professionals argue that mental health assessment should be routinely incorporated into young adults' medical health care. This project is an evaluation of the Behavioral Health Screening Measure (BHSM) that could be integrated into a primary healthcare setting to aid in the identification of mental illness in young adults. First, Receiver Operating Characteristics analysis was used to calculate a cutoff score that distinguishes a sample of 134 young adult outpatients and 233 young adult nonpatients. Second, a sample of 120 young adults that completed BHSM was divided into two groups by using the cutoff score. Analyses suggested that the two groups had significantly different scores on various measures of depression, anxiety, and general well-being. Results suggest that BHSM would be a valid screening instrument for detecting emotional problems in young adults.  相似文献

Choice experiments are used to assess consumer preferences and willingness‐to‐pay (WTP) for different food attributes worldwide. These studies also include credence attributes which are the product attributes that are not immediately observable to consumers without appropriate information and labelling, such as animal welfare, food safety, and social responsibility. Although choice experiment application has considered many of these attributes, studies focused on social responsibility are scant. Building on previous work comparing developed and developing countries, this paper focuses on WTP estimation for social responsibility. Surveys of fruit and vegetable consumers were conducted in United Kingdom (UK), Japan, India, and Indonesia in 2015. Results indicate WTP for an increase from minimum to improved standard for social responsibility ranges from 16% to 30% (median), and 6% to 26% (median) from improved to a high standard. Premiums vary between countries but, overall, demonstrate the significant importance of social responsibility consideration in consumer choices. Significant differences on WTP were observed between Japan and other countries, as well as between UK and Indonesia for the improved social responsibility standard, and across UK, Indonesia, and India for the high standard. Findings contribute to increasing understanding of consumer preferences across countries, revealing significant preference heterogeneity towards social responsibility.  相似文献

The authors tested whether physical self-concept and self-esteem would mediate cross-sectional relations of physical activity and sport participation with depression symptoms among 1,250 girls in 12th grade. There was a strong positive relation between global physical self-concept and self-esteem and a moderate inverse relation between self-esteem and depression symptoms. Physical activity and sport participation each had an indirect, positive relation with global physical self-concept that was independent of objective measures of cardiorespiratory fitness and body fatness. These correlational findings provide initial evidence suggesting that physical activity and sport participation might reduce depression risk among adolescent girls by unique, positive influences on physical self-concept that operate independently of fitness, body mass index, and perceptions of sports competence, body fat, and appearance.  相似文献
