The interaction of light with surfaces results in a number of lighting effects that may serve as valuable visual cues. Previous research on shadows has shown them to be effective in determining the three-dimensional (3-D) layout of a scene, but interreflections have been ignored as cues for spatial layout. Interreflections as well as shadows may help to disambiguate the 3-D layout of objects by providing information about an object's contact with a surface. We generated computer images of a box on an extended textured ground plane that was either in contact with the ground or was slightly above the ground. Images were rendered for four conditions: (1) no shadow + no interreflection, (2) shadow only, (3) interreflection only, and (4) shadow + interreflection. A photometrically incorrect condition was also included. The participants rated the degree of contact for each image on a scale, which was used to generate receiver operating characteristic (ROC) curves and a measure of sensitivity. In the images with no shadows or interreflections, the participants performed at chance levels. Interreflections, shadows, and a combination of interreflections and shadows all resulted in high sensitivity for judging object contact. More important, information from shadows and interreflections can be combined, resulting in near-perfect judgment of surface contact. Interreflections and shadows can be effective cues for object contact. 相似文献

The Comprehensive Services Act for At Risk Youth and Families of Virginia (CSA), is a service, funding, and organizational reform initiative designed to improve the provision of child centered and family focused services within a community setting. We conducted this study in order to assess the feasibility of applying utilization management principles to the CSA in order to improve the appropriateness, quality, and cost effectiveness of this service delivery system. Data were gathered through focus groups, surveys, clinical profiling, and analysis of costs, and service utilization. While overall program costs increased since inception of the program, the costs per child served rose less than the rate of inflation. CSA appeared to be serving children with a high degree of emotional and behavioral difficulties. There was considerable variation among localities in placement patterns. A majority of survey and focus group respondents were willing to consider the application of utilization management principles to the CSA as long as decision making remained within localities. We concluded that there is a constructive role for utilization management approaches to improve the appropriateness and quality of services as well as enhancing efficiency in child mental health. 相似文献

Menopause is a normative life transition that is experienced by virtually all women, yet remains poorly understood. The dominance of the biomedical model results in a unidimensional definition of menopause as a biological event, ignoring the influence of cultural and psychosocial factors. Counselors who use an integrative approach can not only provide accurate biomedical information but also conceptualize menopause as a normative midlife transition. The purpose of this article is to provide a foundation in biomedical issues and to consider how these independently, and in interaction with cultural and psychosocial factors, influence the experience of menopause. 相似文献

We argue that consumers with high self-brand connections (SBC) respond to negative brand information as they do to personal failure — they experience a threat to their positive self-view. After viewing negative brand information, high (vs. low) SBC consumers reported lower state self-esteem. Consumers with high SBC also maintained favorable brand evaluations despite negative brand information. However, when they completed an unrelated self-affirmation task, they lowered their brand evaluations the same as low SBC consumers. This finding suggests that high SBC consumers' reluctance to lower brand evaluation might be driven by a motivation to protect the self rather than the brand. 相似文献

This cross-sectional study examined personal growth and meaning in life among mothers and grandmothers who recently went through major transitions in a woman’s life. It investigated the contribution of the internal resources of perception of self (self-esteem) and perceived characteristics of the situation (cognitive appraisal of threat, challenge, and self-efficacy) and the external resource of perceived social support, as well as two background variables: age, and frequency of meetings between mothers and grandmothers. Participants were 152 first-time mothers 6–24?months after delivery, and their own mothers who were first-time grandmothers (n?=?152). The results showed differential contributions to meaning in life and personal growth in the two generations, indicating that the proposed variables can indeed explain growth and meaning in life in these life stages. They reveal not only the similarities and differences between the response of mothers and grandmothers to these parallel life transitions, but also how information about one generation may help explain the response of the other. The different patterns of associations which emerged for growth and meaning in life are also discussed. 相似文献

In each of three experiments animals received blocking, A+ AX+, in which food was always presented after one stimulus, A, that was occasionally accompanied by another stimulus, X. They also received a simple discrimination, AX+ BX-, in which the presence and absence of food was signaled by two compounds that contained one unique cue, A or B, and one common cue, X. In each of these designs, X can be said to be redundant relative to A as a signal for food. Test trials at the end of training revealed that responding during X was stronger after blocking than after the simple discrimination. These results contradict predictions from theories of learning that assume changes in associative strength of a stimulus are determined by a global error term based on the outcome predicted by all the stimuli that are present for a conditioning trial. The results are interpreted, instead, by assuming either that animals store a memory of every trial to which they have been exposed, or that learning is governed by an error term based on the significance of individual stimuli. 相似文献

The authors examined postural asymmetries during quiet stance and while holding evenly or unevenly distributed loads. Right-hand dominant subjects preferentially loaded their right lower limb when holding no load or a load evenly distributed in both hands, but no differences in center of pressure (CoP) were observed between the left and right limbs. However, longer CoP displacement was observed under the preferentially loaded limb, which may reflect a functional asymmetry that allows quick movement of one limb in response to a potential perturbation. When a load was held only in the nondominant hand, sample entropy decreased in the left (loaded) limb but increased in the right (unloaded) limb, suggesting the unloaded foot compensated for a loss of control flexibility in the loaded foot. 相似文献

Recent reports on Religious Education (RE) in England and Wales highlight the need for guidance on pedagogy and learning. The RE-flect project addressed this by promoting the creation of metacognitively oriented learning environments in primary school RE classrooms. Six primary school teachers and 160 pupils (eight to 10 years of age) took part in the second year of this two year project. Meta-thinking, worldview and resources zones were created in each classroom. Attainment in RE and pupil perceptions of the learning environment were measured. Data from classroom observations, Worldview Profiles (WVP), and pupil and teacher interviews were analysed qualitatively. Results show an overall increase in attainment; a positive change in pupil perceptions of the learning environment; and the ability of pupils to reflect on and articulate their worldviews. Implications for RE curricular and pedagogy are discussed. 相似文献

Behavioral activation (BA) can be as effective as cognitive-behavioral therapy for the treatment of depression in adults, but to date there is little research with adolescents. This is problematic given the recognized need to increase access to evidence-based interventions for depression in young people. We have developed a new adaptation of brief Behavioral Activation (Lejuez, Hopko, Acierno, Daughters, & Pagoto, 2011) specifically for young people: Brief BA for depressed adolescents. In this paper, we use a case example with session-by-session measurement to show how a nonspecialist clinician can deliver this intervention successfully. We discuss the key themes arising from this training case, challenges the clinician faced, and how these were managed through training and supervision. 相似文献
