The Cornell Institute for Research on Children (CIRC) is an intellectual infrastructure funded by the National Science Foundation under the aegis of the Children's Research Initiative, which was spearheaded by Rodney R. Cocking. Cocking's vision of integrated developmental science is an integral part of CIRC's philosophy. CIRC aims to integrate knowledge and paradigms from a variety of fields (e.g., developmental psychology, economics, neuroscience, and pediatrics), which take different perspectives on similar issues (e.g., the effects of toxins on cognitive development), making it explicitly interdisciplinary. The object of CIRC studies is to apply research findings to social policy. To accomplish this, CIRC provides resources to enable teams of scholars from diverse fields to collaborate on policy-relevant questions. CIRC's approach begins by asking policy-makers to define questions for researchers to address, then shepherds the process by which scholars from various relevant disciplines are commissioned to work as a team to answer such questions. To demonstrate the strengths of this approach we describe the six components that comprise CIRC and provide an actual example of a project that CIRC has commissioned as well as a hypothetical example of a project that CIRC could undertake. This article is a progress report, written in an effort to disseminate information about CIRC's agenda.  相似文献

We describe the historic and current use of brief experimental analysis procedures in outpatient clinic and home settings. We discuss some applications of the designs and suggest design modifications for improving internal validity. We describe our application of the designs to longitudinal, in-home programs for children with severe behavior disorders and demonstrate how related versions of brief experimental analysis procedures can be linked to form a more comprehensive evaluation.  相似文献

This study examined group identification and situational ambiguity as moderators of attributions to discrimination and self-esteem following negative feedback. As predicted, high gender-identified women made more discrimination attributions than low identified women when situational prejudice cues were ambiguous, but not when prejudice cues were absent or overt. Also as predicted, women exposed to overt prejudice cues had higher self-esteem than those exposed to ambiguous cues or no prejudice cues. The relationship between discrimination attributions and self-esteem was positive among women exposed to overt prejudice but negative among those exposed to no prejudice. Across conditions, however, the more that women discounted ability as a cause of their negative feedback (i.e., blamed discrimination more than ability), the higher their self-esteem. Results qualify and extend prior research and demonstrate that personal and situational factors moderate both the tendency to make attributions to discrimination and the consequences of those attributions for self-esteem.  相似文献

Pornography use, preference for “porn‐like” sex, masturbation, and sexual and relationship satisfaction were assessed among two samples of men (NStudy 1 = 326, NStudy 2 = 335). Frequent pornography use was associated with sexual dissatisfaction, greater preference for porn‐like sex, and more frequent masturbation in both studies. Pornography use was associated with relationship dissatisfaction in Study 2 only. The data did not support the notion that pornography negatively impacts sexual or relationship satisfaction via preference for porn‐like sex. In fact, it may bolster sexual satisfaction by promoting sexual variety. The data were consistent with a model in which pornography negatively, indirectly affects sexual and relationship satisfaction via masturbation frequency. Pornography use may have multiple opposing influences on sexual satisfaction.  相似文献

This article presents reflections on the seven articles included in this special series. The classification of school attendance problems (SAPs) based on structured checklists of SAP types (school refusal, truancy, school withdrawal, and school exclusion) together with functional analysis opens the way for establishing norms and social referents. We discuss how authorized nonattendance can also be problematic if it is persistent, and that it is important to take this type of SAP into account if the field is to effectively understand and respond to the complex range of bio-psycho-socio-cultural determinants of absenteeism. We highlight other gaps in the current literature, one of which is the lack of attention to evidence-based prevention and early intervention strategies. Avenues for future research are suggested, with emphasis on the need for pragmatic approaches to address the complexities of SAPs. Promising work is beginning to address the SAPs that are prevalent in special populations such as those with autism spectrum disorder. Overall, our reflections highlight the incremental changes that have characterized the field, exemplified by this series of articles, and the promise of transformational change in tackling the major challenge of SAPs as research in the field continues.  相似文献

Three experiments used appetitive conditioning with rats to examine the involvement of elemental and configural processes in positive and negative patterning discriminations. The first experiment demonstrated that negative and, to some extent, positive patterning discriminations were learned more rapidly when these discriminations consisted of stimulus elements that had previously been the reinforced as opposed to the non-reinforced elements of a simple discrimination. Experiment 2 revealed an excitatory summation effect during the early phase of negative patterning learning that depended upon discrimination pretraining. The final experiment demonstrated faster discrimination learning between the compound and the less salient, rather than the more salient, element of an instrumental patterning task. The present set of results were interpreted as reflecting the possibility, consistent with connectionist theory, that internal representations of the conditioned stimuli change over the course of a patterning discrimination.  相似文献

This article examines the psychological impact of participating in sigmoidoscopy screening for colorectal cancer prevention. The 1st study examined psychological well-being at 3 months, in relation to screening outcome, in 4,153 individuals. The 2nd study used longitudinal data to examine changes in psychological functioning from before to after screening in relation both to screening outcome and baseline indicators of vulnerability. There were few psychological differences between those who had received negative results or had polyps detected. These findings were confirmed in the longitudinal study, which also found no evidence for vulnerability to adverse effects among those who were initially most anxious or who perceived their risk of cancer to be higher. The longitudinal data suggested that screening might produce transient positive effects.  相似文献
