Perceived distributions of the characteristics of in-group and out-group members: empirical evidence and a computer simulation 总被引:2,自引:0,他引:2
This research studied 2 properties of perceived distributions of the characteristics of social category members: the probability of differentiating (making distinctions) among category members and the perceived variability (variance) of category members. The results of 4 experiments supported the hypothesis that greater familiarity with a social group leads to greater perceived differentiation and variability regarding that group. In-group members formed more differentiated and variable distributions for groups defined by age and more differentiated distributions for groups defined by nationality. For gender (where students were roughly equally familiar with people of both genders), no in-group--out-group differences occurred. Also, students perceived greater differentiation and variability among classmates over the course of a semester. To explain these results, we developed PDIST, a multiple exemplar model that assumes that people form perceived distributions by activating a set of category exemplars and then judging the relative likelihoods of different feature values on the basis of the relative activation strengths of these feature values. The results of a computer simulation experiment indicated that PDIST is sufficient to explain the results of our 4 experiments. According to the perceived distributions formed by PDIST, increasing familiarity leads to greater differentiation and variability, has a concave impact, and has greater impact on differentiation than on variability. 相似文献

Psychoanalytic implications of anal characterology were operationalized, and an experimental situation devised to test hypotheses of various aspects of interpersonal behavior. Subjects selected for the study had been found to score either high or low on Kline's (Ai3) Anality Scale. Self-disclosure and disclosure reciprocity were shown to be negative functions of anality: productivity and superego measures were also shown to be functions of anality. Self-esteem and socio-economic status did not relate to anality levels, while the hypothesis linking anality with negativism was only partially confirmed. Implications for psychoanalytic and social psychology research are discussed. 相似文献

The general and deep dissatisfaction with the present-day status of health care is of such intensity that one speaks of a health care crisis. What is most disturbing to the physicians is that society directs its accusation mainly at the health care professional for being responsible for this crisis. If we want to abolish the crisis we must try to get a renewed look at its source, i.e., to answer the questions “where did health care go wrong primarily?” and “with whom lies the ultimate responsibility for health care?”. In the following discourse these questions are discussed. Based on the assumption that every human being is a free rational agent the ultimate health care responsibility is assigned to the citizen. Of course, whether such an approach will in fact solve the problems inherent in present-day health systems cannot be predicted. 相似文献

Anatomoclinical correlations of the aphasias as defined through computerized tomography: Exceptions 总被引:7,自引:0,他引:7
We have studied the frequency of exceptions to classical aphasia localizations in right-handed, literate, adult, native speakers of Italian with focal vascular left-hemisphere lesions, correlating clinical and computerized tomography data. Two hundred sixty-seven subjects were given computerized tomography (CT) examinations; lesions were mapped onto lateral diagrams and the sites of the lesions were defined. Patients were then classified as nonfluent aphasics, fluent aphasics, and nonaphasics. Patients with negative CT scans (n = 10) or only "deep" lesions (n = 50) were not studied for anatomoclinical correlations. Of the remaining 207 patients, 36 presented unexpected findings. There were seven cases of fluent aphasia and "anterior" CT lesions and six cases with nonfluent aphasia and "posterior" CT lesions among them. The significance of these findings is discussed. 相似文献

Conclusion Some have argued, following Stalnaker, that a plausible functionalist account of belief requires coarse-grained propositions. I have explored a class of functionalist accounts, and my argument has been that, in this class, there is no account which meetsall of the following conditions: it is plausible, noncircular, and allows for the validity of the argument to coarse-grained propositions. In producing this argument, I believe that I have shown that it might be open to a functionalist to adopt fine-grained propositions; thus, one might be a functionalist without holding that all mathematical beliefs are about strings of symbols (and that the belief that all bachelors are unmarried men is a belief about words).My project in this paper has been minimal in the following sense. I havenot argued thatno functionalist account of belief which meets the three conditions can be produced; rather, I have simply explored the inadequacies of certain sorts of accounts. I think that this is useful insofar as it makes clear the challenges to be met by an account of belief which can play the required role in the argument to coarse-grained propositions. It is compatible with my position that such an account is forthcoming, insofar as I have not produced a functionalist theory of belief which is clearly non-circular, plausible, and which yields fine-grained propositions. Of course, it is also compatible with my position that no plausible, non-circular functionalist account of belief of any sort can be produced. My argument has been that,if one construes such mental states as belief as functional states, no convincing argument has yet been produced that they require coarse-grained objects. 相似文献

Previous research has established that the facial displays of those who listen to stories are influenced by the social context in which this happens. H owever, experienced affect was not measured in these studies, and the story stimuli were not systematically manipulated. We report a study in which participants listened to stories that varied in rated funniness, and that were told by either a friend or a stranger via one of the following channels: Tape recorder, telephone, or face-to-face. D ependent measures included facial activity, subjective feelings, and social motives. We anticipated that facial displays would be influenced by story type and by social context, and that the former effects would be mediated by experienced affect, whereas the latter effects would be mediated by social motives. The funnier story elicited more smiling, but this was not mediated by experienced affect. Social context also influenced smiling, and this effect appeared to be mediated by social motives. 相似文献
