This study examines the public's and physicians' willingness to support deception of insurance companies in order to obtain necessary healthcare services and how this support varies based on perceptions of physicians' time pressures. Based on surveys of 700 prospective jurors and 1617 physicians, the public was more than twice as likely as physicians to sanction deception (26% versus 11%) and half as likely to believe that physicians have adequate time to appeal coverage decisions (22% versus 59%). The odds of public support for deception compared to that of physicians rose from 2.48 to 4.64 after controlling for differences in time perception. These findings highlight the ethical challenge facing physicians and patients in balancing patient advocacy with honesty in the setting of limited societal resources. 相似文献
In real scenes, surfaces in different depth planes often differ in the luminance and chromatic content of their illumination. Scene segmentation is therefore an important issue when considering the compensation of illumination changes in our visual perception (lightness and colour constancy). Chromatic adaptation is an important sensory component of colour constancy and has been shown to be linked to the two-dimensional spatial structure of a scene (Werner, 2003 Vision Research 43 1611 - 1623). Here, the question is posed whether this cooperation also extends to the organisation of a scene in depth. The influence of depth on colour constancy was tested by introducing stereo disparity, whereby the test patch and background were perceived in either the same or one of five different depth planes (1.9-57 min of arc). There were no additional cues to depth such as shadows or specular highlights. For consistent illumination changes, colour constancy was reduced when the test patch and background were separated in depth, indicating a reduction of contextual influences. An interaction was found between the influences of stereo depth and spatial frequency on colour constancy. In the case of an inconsistent illumination change, colour constancy was reduced if the test patch and background were in the same depth plane (2-D condition), but not if they were separated in depth (3-D condition). Furthermore, colour constancy was slightly better in the 3-D inconsistent condition than in the 2-D inconsistent condition. It is concluded that depth segmentation supports colour constancy in scenes with inconsistent illumination changes. Processes of depth segmentation are implemented at an early sensory stage of colour constancy, and they define visual regions within which the effects of illuminant changes are discounted for separately. The results support recent models that posit such implementation of scene segmentation in colour constancy. 相似文献
Processes of self-concept immunization are introduced as a way of reconciling self-concept protection against threatening information with the necessity of acknowledging own failure or losses. Self-immunization works by adaptively changing the subjective operationalization of personal traits, such that skills that individuals believe themselves to be good at are conceived as highly diagnostic, whereas skills that persons do not believe they possess are considered less diagnostic. Three studies are presented to investigate this stabilizing process. Correlational as well as experimental and longitudinal data support the assumption that self-immunization stabilizes central and abstract aspects of the self-concept without ignoring negative information on concrete skills. 相似文献

Two field experiments compared the persuasive impact of communications delivered face-to-face, by telephone, or by letter. In both studies, letters did not differ from faccto-face contacts but telephone calls were less effective. In the second experiment, personalness interacted with communication medium such that addressing subjects by name reduced the impact of face-to-face encounters, increased that of letters, and had no effect on phone calls. A third sample of subjects rated the appropriateness of name usage by salespeople, indicating a salesperson should give his own name but was inappropriately personal when calling the subject by name. The findings support the notion that varying media and name usage varies the psychological distance between communicator and recipient. At appropriate psychological distances, communicators and communications have optimum effectiveness; at too great or too little distance, they lose impact. Thus, not only is selection of proper medium important to communicators but how the medium is used can affect impact. 相似文献
Three models of conditional discrimination learning by pigeons are described: stimulus configuration learning, the multiple-rule model, and concept learning. A review of the literature reveals that true concept learning is not characteristic of the behavior of pigeons in matching-to-sample, oddity-from-sample, or symbolic matching studies. Instead, pigeons learn a set of sample-specific SD rules. Transfer of the discrimination to novel stimuli, at least along the hue dimension, is predicted by a “coding hypothesis”, which holds that pigeons make a unique, but usually unobserved response, R1, to each sample, and that the comparison stimulus chosen depends on which R1 was emitted in the presence of the sample. Convincing evidence is found that pigeons do code sample hues, but there is little evidence that allows one to infer that the “coding event” must have behavioral properties. Parameters of the conditional discrimination paradigm are identified, and it is shown that by appropriate parametric manipulation, a variety of analogous tasks may be generated for both human and animal subjects. The tasks make possible the comparative study of complex learning, attention, memory, and information processing, with the added advantage that behavior processes may be compared systematically across tasks. 相似文献
Average opponent chromatic response functions are presented for use in quantitative models of color perception. Theoretical transformations of photopigment input are related to opponent channel activity. Opponent chromatic activity is, in turn, used to describe a theoretical huenaming curve for an average observer. 相似文献
