Lightness constancy requires that a surface retain its lightness not only when the illumination is changed but also when the surface is moved from one background to another. Occlusion of one surface by another frequently results in a retinal juxtaposition of patches under different illuminations. At such edges, retinal luminance ratios can be much higher than in scenes with a single illumination. We demonstrate that such retinal adjacencies can produce failures of lightness constancy. We argue that they are responsible for departures from perfect lightness constancy in two prior experiments that examined the effects of depth relations on lightness constancy. 相似文献

Fodor and others who think that scientific, computational psychology will vindicate commonsense belief-desire psychology have maintained that belief can be identified with the explicit storage of a token with appropriate content. I review and develop problems for the explicit storage view and show that a more plausible account identifies belief with the disposition to use a token with appropriate content in explicit reasoning and planning processes and as a basis for action. I argue that this type of inner disposition account will also apply to most other common sense attitudes. The result is a realism about commonsense belief-desire psychology that is more modest than Fodor's: While such inner dispositions probably do exist, these states will probably not be the main focus of scientific psychological theories. 相似文献

Utilized a pattern-based approach to discover the different constellations of perceived social transactions separately for family and peer systems and explored the risk and protective functions of these microsystem profiles for both depression and antisocial behavior among a sample of ethnically and racially diverse urban adolescents living in poverty. Measures of perceived social support, involvement and hassles with family and peers, as well as perceived social acceptance and peers' values were entered into two sets of iterative cluster analyses to identify distinct profiles of family and peer transactions. From each of the perceived family and peer transactional analyses, six replicated profiles emerged. Several of the profiles were consistent with expectations from prior literature such as Enmeshing families and Rejecting peer networks, while others were novel and intriguing such as Entangling peers. Family profiles were consistent in their risk and protective associations for both depression and antisocial behavior, while the peer profiles varied in their effects for each developmental outcome. For example, the Rejecting peer profile placed adolescents at increased risk for depression but protected them from antisocial behavior. Implications for future research and preventive intervention are discussed. 相似文献

Examined relationships among negative life events, four locus of control attributions (Internality, Powerful Others, Chance, and God Control), and psychological distress for Korean American versus Caucasian American Protestants. Negative events and Powerful Others beliefs were positively related to distress, whereas Internality was negatively related to distress. Ethnicity and God Control interacted: The relationship between God Control beliefs and anxiety was negative for Caucasians but positive for Koreans. Three-way interactions (Ethnicity × Locus of Control × Negative Events) also emerged. As Caucasians' Powerful Others beliefs increased, the positive relationship between negative events and depression became stronger; Koreans' Powerful Others beliefs had no such effect. As Caucasians' God Control beliefs increased, the negative event–depression relationship changed from positive to negative; the reverse was true for Koreans. Findings support the value of assessing ethnoculture and religiousness in stressful life events research. 相似文献

“Historical hostility” may function as a psychological factor in the lives of African Americans in the United States. Historical hostility is a pattern of responses that many African Americans exhibit, which may stem from their prolonged subjection to inferior treatment in American society. Strategies for addressing historical hostility in African Americans are provided. 相似文献

Widespread collection and use of identifiable information can promote social goods while, at the same time, infringing on personal privacy. Information systems are developing within the context of a fundamental transformation in the organization, delivery, and financing of health care. Changes in the health care system include rapid development of employer-sponsored health coverage, managed care organizations, and integrated delivery systems. These complex, multifaceted arrangements for delivering and paying for health care require ever-more-sophisticated information systems that facilitate extensive sharing of personal data. Systemic flows of sensitive health information occur both vertically and horizontally among employers, hospitals, insurers, laboratories, and suppliers. Beyond this complex web of vertical and horizontal sharing are the multiple demands for information management, quality assurance, research, governmental regulation, and public health. Theoretical problems exist with the law and ethics of informational privacy. The traditional method of exercising control over personal health information is through informed consent. Informed consent, however, within a modern health information infrastructure becomes highly complex. In this kind of environment, the doctrine of informed consent is flawed and does not provide sufficient control over personal information to assure adequate protection of privacy. 相似文献

This paper concerns the problem of teaching people with intellectual handicaps to respond reliably to spoken words and other auditory instructional stimuli. We describe how microcomputer technology can be applied to implement effective auditory stimulus control shaping methods. With hardware and software currently available, it is now possible to adapt procedures that have been previously successful in stimulus control programming with visual stimuli. We describe several techniques for programming gradual stimulus changes (e.g., stimulus fading, stimulus shaping) to promote auditory discrimination learning. Teaching studies with two individuals with severe mental retardation provide illustrative applications and data supporting the feasibility and potential utility of auditory stimulus control shaping methodology. 相似文献
