Human intuition is a rich and useful guide to uncertain events in the environment but suffers from probabilistic incoherence in the technical sense. Developing methods for extracting a coherent body of judgement that is maximally consistent with a person's intuition is a challenging task for cognitive psychology, and also relevant to the construction of artificial expert systems. The present article motivates this problem, and outlines one approach to it. 相似文献

Summary feedback involves withholding feedback from subjects until the last trial in a block is completed, and then presenting feedback about each trial. A variation of this method, called average feedback (Young & Schmidt, 1992), presents subjects with only the mean of the trial block. We investigated whether these methods have similar effects on acquisition and retention of a simple motor skill. Five groups of subjects (n = 16 per group) performed 60 acquisition trials of an aiming task involving both spatial and temporal accuracy. We presented average and summary feedback based on either 5-trial blocks or 15-trial blocks and compared these schedules with every-trial feedback. During acquisition, all groups improved with practice, with a slight tendency for the every-trial condition to have less absolute error than the longer summary and average conditions. Analysis of delayed no-feedback retention tests, however, revealed a strong advantage for the 5-trial summary and average conditions compared with the every-trial condition. In addition, we found that for long blocks of acquisition trials without augmented feedback, the performance variability of those trials was associated with retention performance. Results are discussed in terms of how these different manipulations may make feedback less useful during acquisition, but foster the use of certain information processing activities that enhance overall learning. 相似文献

Single-route models attribute stimulus-response compatibility effects to the difficulty of translation from stimulus to response. Dual-route models propose that compatibility effects reflect in part an additional direct, or automatic, activation route. Selected findings from three lines of research are reported that converge to provide evidence consistent with the view that the automatic activation route plays a role in compatibility effects. The data suggest that the activation produced via this route by relevant stimulus attributes influences response selection only when all mappings of stimuli to responses are known to be compatible. 相似文献

内部分配改革的职务评价技术探新 总被引:4,自引:0,他引:4
建立工资标准系统的关键是确定职务工资率。职务间可比价值成分变异越大,对确定职务工资率的贡献也越大。根据以上研究设想采用方差分析方法进行职务评价。评价步骤包括:职务描述;对职务要素作主成分分析;对职务样本作聚类分析和判别分析;通过方差分析为可比价值各成分建构权重系数ωi。ωi‘满足:(1)ωi≥0;(2)Σωi=1;(3)ωi,间可直接比较;(4)ωi的大小与对应的可比价值成分变异一致。最后将职务评价值线性变换为工资率。在线性方程中配一个常数。和调节系数α以适合组织的管理约束条件。配合两个企业内部分配改革的研究结果显示了方差分析法的有效性和实用性。 相似文献

ABSTRACT Two experiments investigated claims for the efficacy of self-deceptive coping (e.g., Sackeim, 1983, 1988). In Study I the performance of self-deceivers on solvable anagrams was found to he remarkably poor relative to that of non-self-deceivers after both groups were exposed to unsolvable problems. The starkly unambiguous failure experience may have precluded self-deception. Therefore, in Study 2 participants were exposed to unsolvable problems either with or without an excuse. Self-deceivers who encountered failure with an excuse subsequently performed much better on the solvable tasks than those without an excuse. These findings suggest that the use of self-deception following threat is constrained by the availability of contextual ambiguity (e.g., excuses). The effect of the excuse was not related to participants' mood or attributions for performance. 相似文献

The essay centers on Gödel's views on the place of our intuitive concept of time in philosophy and in physics. It presents my interpretation of his work on the theory of relativity, his observations on the relationship between Einstein's theory and Kantian philosophy, as well as some of the scattered remarks in his conversations with me in the seventies — namely, those on the philosophies of Leibniz, Hegel and Husserl — as a successor of Kant — in relation to their conceptions of time.For the physical world, the four dimensions are natural. But for the mind, there is no such natural coordinate system; time is the only natural frame of reference.Gödel, conversation on 15.3.72 相似文献

Causal attributions (i.e., locus, stability, globality) and responsibility attributions (i.e., bad intent, selfish motivation, blame) were assessed in the spouses of 27 depressed psychiatric inpatients and 30 nondepressed dyads to test predictions derived from Hooley's (1987) symptom-controllability model of marital distress. Results indicated that (1) depressed patients and their spouses were less dyadically adjusted than nondepressed spouses, (2) causal and responsibility attributions about depressive behaviors predicted lower dyadic adjustment, and (3) attributions of causality mediated the relationship between group status (depressed or nondepressed) and dyadic adjustment among spouses who had higher expectations for their partner to change. Results suggest that among spouses with a high expectancy for change, depression may be a risk factor for marital distress. 相似文献

DSM-based research on comorbidity has suggested thatdepression andpersonality disorder frequently occur together and that the combination of syndromes is associated with a poor response to treatment for depression. The present study was designed to explore the effect of comorbid Axis II pathology for a sample of 45 inpatients who received treatment for major depression. Both categorical and dimensional ratings of personality disorder were used in the statistical analysis. Positive categorical diagnosis of Cluster C (anxious-avoidant) disorder, as well as higher dimensional rating of Cluster A (odd-eccentric) pathology, was predictive of a poor response to treatment (p<.05), as measured by change in pre-post clinical ratings on the Montgomery-Asberg Depression Rating Scale. These results were construed as indicative of a significant Axis II comorbidity effect in the context of an inpatient, multimodal treatment setting for depression. The results also spotlight the influence of techniques of measurement in determining the outcome of statistical analysis. 相似文献
