Abstract The created co‐creator theology states that human beings have the purpose of creating the most wholesome future possible for our species and the global ecosystem. I evaluate the human aspect of this theology by asking whether it is possible for human beings to do this. Do we have sufficient knowledge? Can we be motivated to do what is necessary to create a wholesome future for ourselves and our planet? We do not at present have sufficient knowledge, but there is reason to believe that with further scientific research we will be able to acquire it. The more difficult question is whether we can be motivated to cooperate on the scale necessary to fulfill this purpose. Evolutionary theories of human sociality, altruism, and cooperation are reviewed. I conclude that it is possible for human beings to fulfill the purpose defined for us by the created cocreator concept, but doing this will not be easy. 相似文献

We investigated the effects of secrecy regarding their mothers' incarceration and social support on behavioral problems in a group of 116 children (aged 6–13 years, M = 9.00). Children with low levels of social support had more externalizing and internalizing problems, and children who had experienced more life stressors reported more internalizing problems. Significant interactions indicated that both externalizing and internalizing problem scores were higher for children whose social support was poor and secrecy scores were low. Our findings suggest that for children already suffering from little or no support from key people, having little or no constraints regarding talking about mothers' incarceration places children at risk for developing behavioral problems. We discuss explanations for the findings and implications for caregivers. 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

This study examined the impact of a cognitive behavioral intervention for nonadherent adolescents with type 1 diabetes. Six youths having problems following the diabetes regimen received training in cognitive restructuring and problem solving during individual sessions. A multiple baseline design across participants was used. Treatment effectiveness was assessed through 24-hr recall adherence interviews with adolescents and frequency of testing data was downloaded from glucose meters. Data was also collected for diabetes-specific stress. Five youths displayed improvement on at least one self-care behavior. Furthermore, the results suggest that the cognitive behavioral intervention was effective in diminishing diabetes-related stress in two participants. Cognitive behavioral interventions show promise for increasing self-care behaviors among nonadherent youths with type 1 diabetes. However, individual youths varied in their response to treatment. Further research is needed in developing procedures to better meet the needs of youths, improve youth participation, and enhance treatment effectiveness. 相似文献

Four studies demonstrated robust within‐ and between‐subject differences in willingness‐to‐pay (WTP) and willingness‐to‐accept (WTA) measures of the value of lottery tickets. Buyers and sellers attended to different numerical cues and interpreted the same numbers differently when setting these two kinds of monetary values. Affective influences appeared to guide the valuation process. Buyers with stronger positive feelings about owning a ticket were willing to pay more for a ticket; sellers with stronger negative feelings about no longer having a ticket required a greater minimum payment in exchange for their ticket. In addition, the WTA/WTP disparity tended to be greater for more affectively‐laden lottery tickets. The results suggest that WTA and WTP prices are constructed using salient numerical cues and affective feelings. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

In recent years, behavior analysts have lamented a disconnection between applied research and practice. In their book, Treatments That Work: Empirically Supported Strategies for Managing Child Behavior Problems, Christophersen and Mortweet (2001) have attempted to bridge this gap for medical and behavioral health providers alike by describing empirically supported treatments, derived from behavior therapy and its application, that are specifically designed for challenging problems commonly seen in typical children. The book is clearly intended for both primary care physicians and behavior therapists, and in this article, we review the extent to which the book meets the needs of each. Discussion centers on the extent to which the book can meet the need for both technical precision and conceptual breadth in training of behavior therapists. We conclude that, in making explicit the connections between research and practice, the authors have provided a useful clinical teaching tool and have also raised important questions about how best to establish collaborative relationships with physicians and promote the use of behavioral technology in primary care. 相似文献

Frequent emesis can cause substantial deleterious effects to a child's health and environment. We conducted a functional analysis of a 3‐year‐old girl's self‐induced emesis and confirmed that emesis was maintained by automatic reinforcement. In a reversal design, we evaluated the efficacy of implementing response blocking at 100% and 50% treatment integrity levels on both attempts and successful production of emesis. One hundred percent blocking, but not 50% blocking, was successful in reducing attempts and emesis below baseline levels. 相似文献

DEVELOPMENTAL BIOLOGY,NATURAL SELECTION,AND THE CONCEPTUAL BOUNDARIES OF THE MODERN EVOLUTIONARY SYNTHESIS 下载免费PDF全文
Using the evolution of the stickleback family of subarctic fish as a touchstone, we explore the effect of new discoveries about regulatory genetics, developmental plasticity, and epigenetic inheritance on the conceptual foundations of the Modern Evolutionary Synthesis. Identifying the creativity of natural selection as the hallmark of the Modern Synthesis, we show that since its inception its adherents have pursued a variety of research projects that at first seemed to conflict with its principles, but were accommodated. We situate challenges coming from developmental biology in a dialectic between innovation and tradition, suggesting on the basis of past episodes that even if developmental plasticity and epigenetic inheritance are aligned with its principles the Modern Synthesis (and its image in the public reception of evolution) will be significantly affected. 相似文献

Working memory (WM) and behavioral inhibition impairments have garnered significant attention as candidate core features, endophenotypes, and/or associated neurocognitive deficits of attention-deficit/hyperactivity disorder (ADHD). The relationship between ADHD-related WM and inhibition deficits remains relatively unclear, however, with inferences about the constructs’ directional relationship stemming predominantly from correlational research. The current study utilized a dual-task paradigm to experimentally examine the relationship between ADHD-related WM and behavioral inhibition deficits. A total of 31 boys (15 ADHD and 16 typically developing [TD]) aged 8–12 years completed WM (1-back and 2-back), behavioral inhibition (stop-signal task [SST]), and dual-condition (1-back/SST and 2-back/SST) experimental tasks. Children with ADHD exhibited significant, large-magnitude WM deficits for the 1-back condition but were not significantly different from children in the TD group for the 2-back, 1-back/SST, and 2-back/SST conditions. Children with ADHD also exhibited significant inhibition deficits for the SST, 1-back/SST, and 2-back/SST conditions, but the within-group effect was not significant. The findings suggest that ADHD-related stop-signal demands are upstream, or compete for, resources involved in controlled-focused attention and/or other central executive (CE), WM processes. 相似文献
