Influence of positive affect on the subjective utility of gains and losses: it is just not worth the risk 总被引:5,自引:0,他引:5
A modification of the procedure originally used by Davidson, Suppes, and Siegel (1956) to measure subjective utility was used to study the influence of positive affect on individuals' perceived value (utility) functions. Results indicated, as expected, that persons in whom positive affect had been induced showed a more negative subjective utility for losses than did controls. This indicates that losses seem worse to people who are feeling happy than to those in a control condition. The subjective utility functions of the two groups did not differ as much, however, when people were considering potential gain. Thus, at least in the situation tested in this study, potential gains did not seem to be more appealing (nor less so) for affect subjects than they did for controls. These findings are discussed in relation to theoretical issues in decision making and work suggesting that positive affect can promote increased sensitivity to losses in situations of potential meaningful loss. 相似文献

The standpoint of realism has been widely used to argue in favour of, or against, particular physical theories. An analysis is made of the adequacy of such arguments, taking an argument by Einstein as a starting point.Some reflexions are given on relativism and invariance. Invariances can be seen as generators of both regularity and paradox in physics.Work on this paper was supported by the Swedish Natural Science Research Council (contract no. F-TV 4775-300). 相似文献

The paper deals with the problem of axiomatizing a system 1 of discrete tense logic, where one thinks of time as the set Z of all the integers together with the operations +1 (immediate successor) and -1 (immediate predecessor). 1 is like the Segerberg-Sundholm system W1 in working with so-called infinitary inference rules; on the other hand, it differs from W1 with respect to (i) proof-theoretical setting, (ii) presence of past tense operators and a now operator, and, most importantly, with respect to (iii) the presence in of so-called systematic frame constants, which are meant to hold at exactly one point in a temporal structure and to enable us to express the irreflexivity of such structures. Those frame constants will be seen to play a paramount role in our axiomatization of 1.The present contribution reports research done under the auspices of the Swedish Council for Research in the Humanities and the Social Sciences (HSFR), project On the Legal Concepts of Rights and Duties: an Analysis Based on Deontic and Causal Conditional Logic.

Summary Methods for the measurement of time-errors (TEs) in the comparison of successive stimulus magnitudes are discussed. Combining a Thurstonian scaling method with the assumption of a fixed subjective width of the equal category, independent of stimulus level, a ratio scale for subjective differences within pairs of successive stimuli is derived. In a tone duration comparison experiment, with the TE defined in the terms of these subjective duration differences, data from four experimental groups were compared, the groups using different modes of judging and responding. Only minor effects of this factor were found, and hence it is concluded that the TE is a true perceptual phenomenon rather than an effect of response bias, criterion bias, or mediating verbal responses to the absolute level of stimulation. The quantitative results are interpreted in terms of a general model for the comparison of successive stimuli, employing the concepts of adaptation and differential weighting of sensation magnitudes.This investigation was supported by grants to the author from the University of Stockholm and from the Swedish Office of Administrative Rationalization and Economy (for computer time), and by grants to Mats Björkman and Hannes Eisler from the Swedish Council for Social Science Research, whose free consultation service at the Department of Statistics, University of Stockholm, also benefited the author. 相似文献

In a double-blind experiment, human males (n = 27) were given either testosterone (40 mg/day), placebo, or no treatment, over a one week period. Subjective and observer assessed mood estimations were conducted before and after treatment. Testosterone levels in saliva were measured with radioimmunoassay. The results revealed a significant placebo effect [c. f. Medicine and Science in Sports 4: 124–126]: After treatment, the placebo group scored higher than both the testosterone and the control group on self-estimated anger, irritation, impulsivity, and frustration. Observer-estimated mood yielded similar results. The lack of a placebo effect in the testosterone group is intriguing, and may be due to secondary effects caused by suppression of the body's own testosterone production, since recorded non-protein bound testosterone did not significantly rise due to treatment. The resultss suggest that androgen usage causes expectations, rather than an actual increase of aggressiveness. © 1994 Wiley-Liss, Inc. 相似文献

The aim of this study was to identify reliable and valid subgroups of spinal pain patients, using data from the Swedish version of the Multidimensional Pain Inventory (MPI-S). A second aim was to test the generalisability of the three patient profiles described in earlier studies on the MPI ("adaptive coper", "dysfunctional" and "interpersonally distressed" patients). The study base consisted of two samples of individuals suffering from long-term, non-specific spinal pain and the results were validated across these samples. Cluster analysis was used to detect distinct groups of patients and the validity of these subgroups was evaluated on variables not used to generate the cluster solution. One subgroup was characterised by lower pain severity, lower interference with everyday activities, lower affective distress and higher life control than the other two subgroups. This patient profile was similar to the MPI adaptive coper patients. A second subgroup resembled the dysfunctional patient profile, thus displaying a worse adjustment to chronic pain than the AC patients. The third patient group reported significantly lower levels of social support from "significant others" than the other subgroups. This patient profile was similar to that of the interpersonally distressed patient group. Taken together, the results support the reliability, validity and generalisability of three subgroups of chronic pain patients derived from the MPI-S. 相似文献

Sandal, G. M. Bye, H. H. & Pallesen, S. (2012). Personality trait inferences of Turkish immigrant and neutral targets: An experimental study. Scandinavian Journal of Psychology 53, 528–533. The study investigated whether personality traits attributed to immigrant targets differ from personality inferences made for a neutral target, and whether trait attributions differ for assimilated and integrated immigrant targets. Participants (n = 340) were randomized to one of three conditions in which they read the same story about a person, but where the person was described as either: (a) an assimilated Turkish immigrant; (b) an integrated Turkish immigrant; or (c) neutral (no nationality or religious practice indicated). Subsequently, they rated the personality of the described person on the NEO‐Five Factor Inventory (observer rating version) and completed the Balanced Inventory of Desirable Responding (Impression Management scale) with reference to themselves. Both immigrant targets were rated as significantly higher on extraversion and lower on neuroticism than the neutral target. The integrated target was rated as more open than the neutral target, and as higher than the assimilated target on neuroticism when controlling for impression management. 相似文献

A self-determination theory perspective on motivation assumes that basic need support is a prerequisite for motivation, achievement, and well-being in several domains of life. In the present cross-sectional study, a representative sample of 2.594 Norwegian students in their final year of lower secondary education and their first year of upper secondary education responded to a survey measuring the students’ perceptions of their teachers’ autonomy support, the students’ personal achievement goals, perceived school performance, and life satisfaction. The purpose was to investigate the structural relation between these variables, as well as grade level and gender differences. The results showed that all achievement goals (mastery, performance approach and performance avoidance) were positively predicted by autonomy support. Perceived school performance and life satisfaction were predicted by autonomy support and achievement goals, but there were some grade and gender specific relations. Furthermore, students in their first year of upper secondary education had a higher mean level of all motivational variables. Finally, mastery goals were more important for girls than boys, whereas performance goals were more important for boys than girls. In conclusion, both academic achievement (perceived school performance) and life satisfaction may be considered as important indicators of adjustment to life, and they are related to the students’ perception of teachers’ autonomy support as well as the students’ own motivation for learning. However, the mean level of these variables is partly accounted for by grade level and gender. 相似文献
