A theoretical approach to the understanding of human behavior in uncertain outcome situations is suggested, an approach which draws upon utility theory, decision-making theory, and statistical association theory. Experimental evidence supporting this approach as opposed to alternative approaches is summarized. Three different formalizations are presented, and a variety of experimental tests is suggested.This paper was written while the author was at the Center for Advanced Study in the Behavioral Sciences, and it has benefited greatly from discussions with many colleagues there. In particular, some of the features of Models I and II emerged from work with Robert P. Abelson, and Model III was developed to its present state partly as a result of consultations with Claude Shannon, and John C. Harsanyi (of the Department of Economics at Stanford University). The treatment of all three models was sharpened during many discussions with Robert M. Solow. 相似文献

Although cerebral anoxia is not thought to be responsible for triggering near-death experiences (NDEs), the issue is not so clear in the case of hypercapnia. Detection of normal blood gases in Michael Sabom's (1982) case study seems to be the major reply to suggestions that hypercapnia may have a causal role in NDEs. We argue, however, that routine arterial measures of blood gases are not a reliable indicator of cerebral levels. 相似文献

Previous studies of infants’ ability to integrate and to utilize relative motion as information for form in the absence of structural cues have primarily involved motions that are uniform in rate, direction, and path within the form to be constructed. In the present study, we examined infants’ ability to integrate relative motion information from motions that are nonuniform along these dimensions, and from this integrative process to construct a coherently rotating two-dimensional form. Infants’ ability to integrate nonuniform motion was measured with regard to their ability to discriminate the rotating form from a noncoherent control display containing the same absolute motions. The results showed that discrimination of the coherent and incoherent displays was not demonstrated until 7 months of age. Two additional experiments were conducted to rule out the possibility that this discrimination was based on the detection of local regions of coherence, rather than the perception of the global rotating form. In both experiments, the results did not support discrimination based exclusively on local cues alone. From the combined results of all three experiments, we conclude that infants demonstrate the capacity to integrate the information contained within nonuniform trajectories into a coherent structure by 7 months of age. 相似文献

On the basis of a conditioning analysis of the orientation-contingent color aftereffect (McCollough effect, ME), orientation stimuli become associated with simultaneously presented chromatic stimuli. This account suggests that decreasing the contingency between the grid orientation and color should decrease the strength of the aftereffect. Results of previous research indicate that decreasing the temporal contingency (by presenting homogeneous chromatic stimuli between presentations of chromatic grids) does not decrease the ME. However, it has been suggested that the appropriate contingency-degradation procedure would involve decreasing spatial (rather than temporal) contingency. That is, the illusion should be attenuated by extending the color beyond the confines of the grid. Contrary to this hypothesis, the results of the present experiments provide no evidence that decreasing the spatial contingency between grid and color decreases the ME; rather, the aftereffect is increased by such a manipulation. 相似文献

In the typical induction of the orientation-contingent color aftereffect (CCAE), the stimuli are composed of elements that differ in both color and luminance. Three experiments are reported that show that chromatic contrast between stimulus elements is insufficient for the induction of the orientation-CCAE and that luminance contrast is necessary. These experiments expand on previous research concerned with the role of luminance contrast in the induction of orientation-CCAEs by eliminating alternative explanations. 相似文献

The purpose of the current study was to examine the psychometric properties and clinical utility of the Scale for Suicide Ideation (SSI) for children. The SSI was administered to 100 children who were hospitalized. Data were not used from 13 subjects due to the presence of a psychotic disorder or IQ less than 70, leaving 87 participants. The SSI was examined regarding its internal consistency, concurrent validity, construct validity, and factor structure when used with children. Based on the findings, the SSI appears to have adequate psychometric properties and can be used by clinicians and researchers examining children in an inpatient setting. Recommendations for clinicians are included to help make the SSI more functional in use for children. 相似文献

In Biro and Siegel (1992) we argued that a theory of argumentation mustfully engage the normativity of judgments about arguments, and we developedsuch a theory. In this paper we further develop and defend our theory. 相似文献

Abstract— A conceptual model based on staffing theory was applied to previously collected survey data from a representative sample of American workers The model links organizational size, workload, work experience variables (felt responsibility and involvement, assessments of work associates), and work outcomes (job satisfaction, work self-esteem, stress symptoms) Path analyses indicated that the model fit data from all waged and salaried workers relatively well When the model was applied to subsamples of new and established employees and of employees from two contrasting occupational groups (professional-technical workers and operative workers), somewhat different patterns emerged The study illustrates the benefits of applying psychological theories across subdisciplines, as well as the limitations of generalizing research findings across different categories of workers We suggest that localized theories and fine-grained analyses of workplace events could help to make research more applicable to work settings 相似文献
