This paper examines two dimensions of concurrent verbal protocol validity. First, whether verbalization affects process and outcome (reactivity) was examined by comparing concurrent verbal protocol traces with those from a computer search process tracing method, the latter being a complete trace of information acquisition from experimental materials. Earlier findings that verbalization affects time were confirmed. However, verbalization did not affect amount and pattern of acquisition or accuracy of judgments. Second, whether concurrent verbal protocols are complete was examined by comparing concurrent verbal protocol and computer traces that were simultaneously obtained in a treatment in which subjects verbalized as they acquired information from the computer. The verbal traces less completely captured information acquisition behavior than computer search. This suggests that, although concurrent verbal protocols provide greater insight into decision behavior than computer search, the latter is a more reliable information-acquisition trace. Thus, if information acquisition is of primary interest and if computer search activities can be naturally integrated into performing the primary task, computer search is preferred to concurrent verbal protocols. However, if information use or retrieval from long-term memory is of primary interest, concurrent verbal protocols are preferred to computer search. Finally, this paper examined whether the simultaneous use of concurrent verbal protocols and computer search provides traces of information acquisition and use that are as complete as when each method is independently applied. Although computer search tended to limit subjects verbalizations of evaluative operators, this effect may be eliminated by practice on the computer prior to collecting data. 相似文献

It is well known that the lexicographic aggregation of complete preorders gives a complete preorder. Unfortunately, this property is no longer true when the lexicographic rule is applied to semiorders. In this paper we study some ways of defining a lexicographic aggregation of semiorders and the properties of the resulting structures. 相似文献

Sense of agency (SoA) describes the experience of being the author of an action. Cue integration approaches divide SoA into an implicit level, mostly relying on prospective sensorimotor signals, and an explicit level, resulting from an integration of sensorimotor and contextual cues based on their reliability. Integration mechanisms at each level and the contribution of implicit to explicit SoA remain underspecified. In a task of movements with visual outcomes, we tested the effect of social context (contextual cue) and sensory prediction congruency (retrospective sensorimotor cue) over implicit (intentional binding) and explicit (verbal judgments) SoA. Our results suggest that prospective sensorimotor cues determine implicit SoA. At the explicit level, retrospective sensorimotor cues and contextual cues are partly integrated in an additive way, but contextual cues can also act as a heuristic if sensorimotor cues are highly unreliable. We also found no significant association between implicit and explicit SoA. 相似文献

We present a theory of decision by sampling (DbS) in which, in contrast with traditional models, there are no underlying psychoeconomic scales. Instead, we assume that an attribute's subjective value is constructed from a series of binary, ordinal comparisons to a sample of attribute values drawn from memory and is its rank within the sample. We assume that the sample reflects both the immediate distribution of attribute values from the current decision's context and also the background, real-world distribution of attribute values. DbS accounts for concave utility functions; losses looming larger than gains; hyperbolic temporal discounting; and the overestimation of small probabilities and the underestimation of large probabilities. 相似文献

The group therapist often and perhaps necessarily personifies Incohesion and displays its predominant defenses of contact-shunning Aggregation, and merger-hungry Massification. Hence, I am I:A/M. In Hopper's group example, and in each of three of this author's groups, the therapist displayed aggregative and massified defenses, countertansferential duals of basic assumptive transferences. In any therapeutic interaction, it is possible to find elements of incohesion, dependency, pairing, and fight/flight. The incohesion concept has significant clinical utility. A theoretical question remains, whether Hopper's proposed axis of experience and defense merits the special status, basic assumption, or whether incohesion may be collapsed into the existing triad of basic assumptions. 相似文献

There is a contemporary conflict between individualistic andcommunitarian conceptions of rationality. Robert Goodin describes it asa conflict between an enlightenment individualistic conception of a``sovereign artificer'' and ``a socially unencumbered self'' ascontrasted with the communitarian conception of a ``socially embeddedself'' whose identity is formed by his or her community. Should wejustify and explain rationality individualistically or socially? This isa false dilemma when consensus is reached by a model articulated byKeith Lehrer and Carl Wagner. According to this model, the consensusresults from the positive weights individuals give to others and use tocontinually average and, thus, aggregate their allocations. Aggregationconverges toward a consensus in which the social preference and theindividual preferences become identical. The truth of communitarianismis to be found in the aggregate and the truth of individualism in theaggregation. The original conflict dissolves in rational consensus. 相似文献

We investigate under what conditions a given set of collective judgments can arise from a specific voting procedure. In order
to answer this question, we introduce a language similar to modal logic for reasoning about judgment aggregation procedures.
In this language, the formula
expresses that is collectively accepted, or that is a group judgment based on voting. Different judgment aggregation procedures may be underlying the group decision making.
Here we investigate majority voting, where holds if a majority of individuals accepts, consensus voting, where holds if all individuals accept, and dictatorship. We provide complete axiomatizations for judgment sets arising from all three aggregation procedures. 相似文献

Two studies examined a novel prediction of the causal Bayes net approach to judgments under uncertainty, namely that causal knowledge affects the interpretation of statistical evidence obtained over multiple observations. Participants estimated the conditional probability of an uncertain event (breast cancer) given information about the base rate, hit rate (probability of a positive mammogram given cancer) and false positive rate (probability of a positive mammogram in the absence of cancer). Conditional probability estimates were made after observing one or two positive mammograms. Participants exhibited a causal stability effect: there was a smaller increase in estimates of the probability of cancer over multiple positive mammograms when a causal explanation of false positives was provided. This was the case when the judgments were made by different participants (Experiment 1) or by the same participants (Experiment 2). These results show that identical patterns of observed events can lead to different estimates of event probability depending on beliefs about the generative causes of the observations. 相似文献

IntroductionThe traditional approach to value judgments involves determining the position of an individual on a scale designed to evaluate the underlying mechanisms and dimensions of judgments.ObjectiveThe purpose of this study was to develop and validate a scale among a general population and to apply it to individuals particularly affected by, or directly involved in, acts of transgression.MethodThe scale comprises three types of behavior involving an expression of personal values (atypism or idiosyncratic behavior) or a violation of moral or conventional standards. Subjects were asked to assess a range of actions and behaviors on three dimensions (Likert format): seriousness, excusability and rejection of the transgressor.Results and conclusionAs predicted, factor analysis shows a clear hierarchy of values. The results demonstrate the multidimensional nature of the instrument and indicate good reliability. Tolerance and severity indices were developed to understand the underlying dynamics of social and moral judgments. The study found that inmates’ judgments of violations and transgressions differed in some respects from the judgments made by the general population. The influence of context and the role of group membership as an explanatory factor are examined from the point of view of the identity strategies used. 相似文献
