The question addressed in this study is whether experts are better calibrated than lay people. We investigated how well people are calibrated when they assess the probabilities of card combinations in the game of blackjack. Three groups of subjects were used: professional dealers, statistical experts, and control subjects. The results showed that experience and statistical expertise do not make people better calibrated in this task. It is argued that the concept of calibration is not wholly appropriate to describe the obtained deviations from the normatively correct responses. This is illustrated by a discriminant analysis performed on the signed deviation scores, which resulted in an almost perfect separation of the three groups, although they were overlapping with respect to calibration. 相似文献

The aim of this paper is to describe a study which investigated the influence of organizational factors on job involvement and specialization involvement. It was hypothesized that rank, self-expression, participation in decision making, and career factors affect job and specialization involvement. The independent variables were chosen by considering an extension of Schein's (1971, Journal of Applied Behavioral Science, 7, 401–426) “career cone” concept. The hypotheses were tested using a sample of Australian Army officers (N = 384) in a questionnaire survey. The results showed that job involvement is associated primarily with self-expression, although the latter is influenced in turn by participation in decision making, and that specialization involvement is associated with both self-expression and career factors. Rank does not affect either involvement variable. It was concluded that Schein's concept is a useful guide to theory and research on career attitudes. The results support the proposition that job and specialization involvement are distinct constructs. Implications for organizations are discussed. 相似文献

Situational performance constraints, task interest, and pay contingencies were manipulated in a laboratory study in order to investigate the cognitive mechanisms associated with the previously observed detrimental effects of constraints on affective task reactions. It was hypothesized that feelings of task competence and self-determination would account for both the direct and the interactive effects of constraints on motivation and satisfaction. The results of the study indicated that despite the fact that participants' performance was being constrained and they were aware of these constraints, the mere presence of the constraints alone failed to result in lower levels of satisfaction or motivation on a proofreading task. Post hoc analyses suggested that the constraints, in fact, led to negative affective task reactions when they also reduced participants' feelings of competence and self-determination. Interestingly, participants' generalized locus of control was associated with such effects. Internals tended to maintain stronger feelings of competence and self-determination than externals in the presence of constraints, thereby also maintaining greater motivation and satisfaction. 相似文献

In this paper I formulate an approach for evaluating probabilistic forecasts in terms of signal detection theory. Signal detection theory provides a powerful perspective for this type of problem, and a rich empirical background including methodological tools as well as an extensive body of research in many domains. I propose procedures which emphasize the maximization of expected utility for the decision maker who uses the forecasts. Further, I suggest approaches to obtaining indices of calibration and resolution within this framework. I also present arguments that the proposed indices will exhibit the same basic properties as do decompositions of Brier's (1950, Monthly Weather Review, 78, 1–3) mean probability score. However, the properties may be reflected in different ways, and hence, the present methods may lead to different conclusions about forecasting ability. Finally, I argue that the use of an expected utility loss function makes this approach more appropriate for practical applications as well as for theoretical research than other procedures with more arbitrary loss functions. 相似文献

The present study, employing a 2 × 2 true-experimental design and regression analyses assessed the main and interactive effects of feedback consistency (consistent vs inconsistent), and feedback favorability (acceptable vs superior), for feedback given at two time periods on measures of perceived feedback accuracy and self-perceived task competence. Among the study's findings were that (a) the perceived accuracy of feedback at the second period was a function of the favorability of feedback received at the first time period, (b) the self-perceived task competence levels of subjects were jointly determined by the favorability of feedback received at both time periods, and (c) the perceived accuracy of feedback was a function of its consistency. Organizational implications of the study's results are offered. 相似文献

An assessment instrument was developed to measure children's perceptions of stressors in their lives, as well as their experiences and emotional reactions to these stressors. Two approaches from the adult literature, major life events and daily hassles, were compared for children. In addition, a comparison between children's and professionals' ratings of the severity of various stressors was made, as well as an examination of the relationship of experience and self-reported reaction to children's ratings. Results indicate that children's ratings of the severity of stressors do differ from adults', particularly when children have experienced the stressor. Further investigation in the study of childhood stress incorporating children's perceptions is proposed. 相似文献

Early accounts of intentional forgetting relied exclusively on mechanisms that operate at encoding. The results of more recent experiments indicate that memory-retrieval inhibition also is involved, thus linking waking intentional forgetting with hypnotic amnesia. The present Experiment 1 was designed to provide further support for the retrieval-inhibition hypothesis by testing four alternative explanations for some of the recent results. Experiment 2 examined the role of word affect in both intentional forgetting and unintentional forgetting to evaluate theoretical interpretations of the retrieval mechanisms thought to be involved. Unintentional forgetting of negative words was consistent with a repression-like interpretation, whereas intentional forgetting of negative words appeared to be limited by sensitization. Personality correlates of the recall results were identified and were found to be in support of these interpretations. 相似文献

This paper tests a meta-model of youthful marijuana use on students in Grades 11, 12 and 13. Although the specific models for each grade varied in detail, all followed a meta-model making the following assumptions: (1) that use or nonuse of marijuana depends primarily on attitude towards use; (2) that attitude largely reflects the perceived functional and dysfunctional consequences of use; and (3) that what people perceive as functional or dysfunctional depends on relevant personality characteristics. All three models showed satisfactory goodness-of-fit in terms of nonsignificant overidentification tests (minimum P > 0.25) and small discrepancies between observed correlations and the corresponding theoretically implied correlations. A notable feature of the Grade 13 data in contrast to those for Grade 12 and previously reported findings was the seeming unimportance of the perceived value of marijuana use for gaining acceptance from peers. It was suggested that this might reflect the selective survival into Grade 13 in the sampled community of more independently-oriented students. 相似文献

Personnel representatives (N = 52) were shown one of four videotaped job interviews in which the verbal content of the 16-min interview was identical, but the interviewee's nonverbal behavior was manipulated. A “low nonverbal” interviewee was defined by minimal eye contact, low energy level, lack of affect and voice modulation, and a lack of speech fluency. The “high nonverbal” interviewee demonstrated the opposite behavior on each of these components. The subjects were asked to rate the videotaped candidates on dimensions previously identified as critical in influencing a job interviewer's decisions. Nonverbal behavior was found to have a significant effect on almost every rating made by subjects in this study. After reviewing the entire 16-min interview, 23 of the 26 subjects who saw the “high nonverbal” candidate would have invited him/her for a second interview. All 26 of the subjects who saw the “low nonverbal” candidate would not have recommended a second interview. 相似文献
