One hundred twelve airline passengers reporting their luggage lost to the baggage retrieval service in a major international airport were interviewed after their interaction with an airline agent. Participants were asked to rate their emotional state before and after the interaction with the agent and to provide information on how they had appraised the situation. The data are interpreted with respect to (1) type and intensity of the emotions felt in this situation, (2) appraisal theory predictions of emotion elicitation and differentiation, and (3) emotional change in the course of the interaction following reappraisal of the situation. 相似文献

How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation. 相似文献

This study of kindergarten-aged hyperactive children evaluated the effects of three modes of treatment in relation to an untreated control group. The treatments were administered over a 3-month period and included cognitive behavior modification, methylphenidate, and the two treatments combined. A follow-up assessment was done approximately 1 year later at the end of the first grade. Analyses of psychological, rating scale observational, and interview data showed that hyperactive children became less symptomatic over time;the data did not provide evidence indicating that any of the treatments studied was more effective than any other or than no treatment at all.This research was supported by grants from the Ontario Mental Health Foundation (Grant No. 701-76/78) and The Hospital for Sick Children Foundation (Grant No. 77-22). The authors wish to thank Mr. Syl Sauro, of the Etobicoke Board of Education, and Mrs. M. Stijovic, of the Etobicoke Community Health Department, for their cooperation. 相似文献

Despite a renewed interest in the philosophical prehistory of logical empiricism, several texts by prominent figures such as, e.g., Moritz Schlick and Hans Reichenbach, published in non-standard journals, have escaped the notice of scholars. Here, a hitherto virtually unknown but significant review of Moritz Schlick's influential book Allgemeine Erkenntnislehre [1st ed. 1918] written by Hans Reichenbach in 1919/20 is reprinted together with comments about its background and the later development, relying on and citing from the unpublished correspondence between Schlick and Reichenbach in 1920. Since they later became the leading figures in the so called Vienna and Berlin circles respectively, this episode marks an important stage in the gradual emancipation of scientific philosophy from its (neo)Kantian roots. 相似文献

Several studies of choice behavior (risk taking) in achievement-oriented situations are reanalyzed. The usual ways of pooling all choices over trials and subjects conceal the series of subjects' decisions and the dynamics inherent in these decisions. A basic strategy of subjects in an achievement-oriented choice situation seems to be to start with an easy task, choose a more difficult one whenever you succeed, and stay mostly at the same difficulty level whenever you fail. A computer model, in which such simple assumptions are made, generates preference functions over the order of difficulty levels that are indistinguishable from those found in empirical studies. It is concluded that the study of choice behavior in achievement-oriented situations should be based on the analysis of the series of single decisions by one subject. For this we need models that allow the predictions of such decisions and the prediction of action-controlling cognitions and emotions. 相似文献
