We have proposed a novel interactive procedure for performing decision analysis, called Robust Interactive Decision Analysis (RID), which permits a decision maker (DM) to voluntarily and interactively express strong (viz, sure) binary preferences for actions, partial decision functions, and full decision functions, and only imprecise probability and utility function assessments. These serve as INPUTS TO operators to prune the state probability space and decision space until an optimal choice strategy is obtained. The viability of the RID approach depends on a DM's ability to provide such information consistently and meaningfully. On a limited scale we experimentally investigate the behavioral implications of the RID method in order to ascertain its potential operational feasibility and viability. More specifically, we examine whether a DM can (1) express strong preferences between pairs of vectors of unconditional and conditional payoffs or utilities consistently; (2) provide imprecise (ordinal and interval) state probabilities that are individually as well as mutually consistent with the state probabilities imputed from the expressed strong preferences. The results show that a DM can provide strong individually and mutually consistent preference and ordinal probability information. Moreover, most individuals also appear to be able to provide interval probabilities that are individually and mutually consistent with their strong preference inputs. However, the several violations observed, our small sample size, and the limited scope of our investigation suggest that further experimentation is needed to determine whether and/or how such inputs should be elicited. Overall, the results indicate that the RID method is behaviorally viable. 相似文献

Correspondences between verbal responding (saying) and nonverbal responding (doing) may be organized in terms of the classes of verbal/nonverbal relations into which particular instances of verbal/nonverbal response sequences can enter. Contingency spaces, which display relations among events in terms of the probability of one event given or not given another, have been useful in analyses of nonverbal behavior. We derive a taxonomy of verbal/nonverbal behavior relations from a contingency space that takes into account two conditional probabilities: the probability of a nonverbal response given a verbal response and that probability given the absence of the verbal response. For example, positive correspondence may be said to exist as a response class when the probability of doing is high given saying but is otherwise low. Criteria for other generalized classes, including negative correspondence, follow from this analysis. 相似文献

New theological understanding can emerge with the advancement of scientific knowledge and the use of new concepts, or older concepts in new ways. Here, the authors present a proposal to extend the concept of “rescue and recovery” found in the United Nations Law of the High Seas, off-world and within a broader purview of other intelligent and self-aware species that humans may someday encounter. The notion of a morality that extends to off-world species is not new, but in this analysis, rescue and recovery become an imperative when any intelligent and self-aware species is in harm's way. Rescue and recovery encompass a necessary action component except perhaps in those cases where rescuers are in danger. The authors explore three biblical examples of rescue and recovery to derive a fundamental meaning of the concept. 相似文献

比较研究-影响中美儿童计算能力差异的认知因素 总被引:2,自引:0,他引:2
本研究要确定中美儿童基本计算技能的差异是否与他们使用的解题策略和基本加工过程的速度有关。为此,对中美两国的一年级儿童进行了书面计算能力测验,以及一组计算机呈现的加法作业。中国儿童在计算能力测验上表现出3:1的操作优势。中美儿童使用的解题策略种类一样,但是,中国儿童在策略综合运用的发展程度上超过美国儿童,检索策略的加工速度也超过美国儿童。显然,策略运用和加工速度的差异促成了中国儿童在计算能力测验上的优势. 相似文献

该文提出了计量测验效度的一种统一方法。首先,根据测量目标由测验编制者提出一组可能的线性拟合模型,拟合模型的集合称作“测量目标结构空间”。然后运用实证性因素分析对各个假设的拟合模型进行多方面的拟合良好性检验。若其中的某一假设模型能最优地拟合预测资料,则该模型中的公共因素的方差总贡献与观测变量的总方差的比就可定义为该测验的效度 相似文献

Polly Young-Eisendrath 《The Journal of analytical psychology》1997,42(4):637-652
Introducing the basic assumptions of constructivism as a philosophical position, this paper illustrates how Jung's psychology - especially complex, archetype and transcendent function - is consonant with constructivism. Further, the paper explores some clinical implications of constructivism by reviewing the problems of chronic projective-identification in a stalemated analytic case, drawing on the contributions of Winnicott, Ogden and Modell in expanding our understanding of, and facility with, the transcendent function. 相似文献

运用规则空间模型识别解题中的认知错误 总被引:13,自引:1,他引:12
运用规则空间模型识别学生解题中的认知错误,该模型将认知心理学,项目反应理论和数据库的代数理论相结合,将被试的二值反应模式映射为笛卡尔乘积空间的一组序偶,然后计算被试和错误规则在该空间的代表性位置之间的马氏距离,并通过贝叶斯决策准则划分被试的错误类型,根据644名中学生对30个数学题目的反应,识别出其中86%的学生可以被划分人18种认知错误类型中。 相似文献

An alternating least squares method for iteratively fitting the longitudinal reduced-rank regression model is proposed. The method uses ordinary least squares and majorization substeps to estimate the unknown parameters in the system and measurement equations of the model. In an example with cross-sectional data, it is shown how the results conform closely to results from eigenanalysis. Optimal scaling of nominal and ordinal variables is added in a third substep, and illustrated with two examples involving cross-sectional and longitudinal data.Financial support by the Institute for Traffic Safety Research (SWOV) in Leidschendam, The Netherlands is gratefully acknowledged. 相似文献

采用事件相关电位(ERP)技术考察了情绪语音影响面孔表情识别的时间进程。通过设置效价一致或不一致的“语音-面孔”对,要求被试判断情绪语音和面孔表情的效价是否一致。行为结果显示,被试对效价一致的“语音-面孔”对的反应更快。ERP结果显示,在70-130ms和220-450ms,不一致条件下的面孔表情比一致条件诱发了更负的波形;在450-750ms,不一致条件下的面孔表情比一致条件诱发更正的后正成分。说明情绪语音对面孔表情识别的多个阶段产生了跨通道影响。 相似文献
