We evaluated the accuracy of peer ratings of roommates’ personality characteristics, against roommate self-ratings, as a function of rating domain observability. Instead of the usual ratings of broad personality traits, however, our domains represented peer ratings of narrow exemplars of personality traits. Specifically, we compared roommate ratings on (a) observable trait-related behaviors with (b) unobservable trait-related attitudes or beliefs. We observed greater self-peer agreement in rating behaviors, in general, than in rating beliefs. We also observed greater tendency of raters to adopt an assumed similarity heuristic when judging their roommates’ attitudes and beliefs than their behaviors. We discuss the contribution of these findings to understanding the determinants of accuracy in personality judgments and developing best practices for personality assessment.  相似文献

For many decisions we make, we are more likely to receive feedback about some outcomes than about others, and thus we must operate under conditions of asymmetric partial feedback. In this paper, we examine the effects of asymmetric partial feedback on decision making across three experiments. Experiment 1 examines the effects of four partial feedback schedules on decision making in a single‐attribute auditory detection task. Experiment 2 examines these same schedules in the context of a simulated experiment in which virtual participants perform a multi‐attribute choice task. Experiment 3 then examines effects of one partial feedback schedule representative of a real‐world decision‐making domain (personnel selection) using an ecologically informed multi‐attribute choice task. All three experiments reveal that asymmetric partial feedback primarily impacts on response‐bias, a parameter of signal detection theory. These findings can be explained in terms of decision makers' attempts to maximize accuracy and the fact that shifts in response‐bias will, under partial feedback, produce misleading impressions of greater accuracy.

Decision makers use confirmatory search strategies in judgment tasks. As a result of this, their attention towards task‐relevant cues is biased in favor of cues supporting available responses. Changing these responses can alter the cues used in the judgment task and, subsequently, alter beliefs. We use this mechanism to predict and explain the emergence of the asymmetric dominance effect in judgment. In four sets of experiments, we document systematic changes in belief, as dominated options are added to the response set. These effects emerge for a number of naturalistic judgment tasks and are mediated by the increased accessibility of decoy‐supporting cues. Finally, these effects can be eliminated when the decision maker's attention is drawn towards the cues supporting the non‐dominant response. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

Perceived similarity is influenced by both taxonomic and thematic relations. Assessing taxonomic relations requires comparing individual features of objects whereas assessing thematic relations requires exploring how objects functionally interact. These processes appear to relate to different thinking styles: abstract thinking and a global focus may be required to explore functional interactions whereas attention to detail and a local focus may be required to compare specific features. In four experiments we explored this idea by assessing whether a preference for taxonomic or thematic relations could be created by inducing a local or global perceptual processing style. Experiments 1–3 primed processing style via a perceptual task and used a choice task to examine preference for taxonomic (versus thematic) relations. Experiment 4 induced processing style and examined the effect on similarity ratings for pairs of taxonomic and thematically related items. In all cases processing style influenced preference for taxonomic/thematic relations.  相似文献

People believe that they have shared an identical subjective experience—that they have I-shared—when they react identically and simultaneously to the same stimulus. Despite growing evidence for I-sharing, researchers have yet to ask whether simultaneity really makes a difference. We test the importance of simultaneity for I-sharing effects. Participants played prisoner’s dilemma with someone who shared their subjective self, their objective self, or neither. Some participants learned this information immediately; others, after a short delay. Time delay decreased cooperation in the subjective similarity condition, but not in the objective similarity or neither conditions. These findings underscore the importance of simultaneity for I-sharing effects and highlight the implications of I-sharing for cooperation and self-interested behavior.  相似文献

This work introduces a methodology to find solutions corresponding to different purposes in a multiple attribute decision‐making problem under fuzzy environment. The discernment of purpose‐based solutions becomes important when the problem is defined vaguely and solution is targeted to heterogeneous population. Depending on the purpose, for which the solution is sought, the attributes are identified and weighted in an appropriate proportion. The level of similarity between a pair of attributes plays an important role to determine the aggregated value of attributes specific to a purpose. Our work determines the similarity levels between a pair of attributes by calculating their maximum attainability in presence of each other. The achievement of an attribute in presence of another is represented as a fuzzy set in the unit interval. The crisp equivalents of the fuzzy sets in the unit interval are used to define their simultaneous satisfaction denoted as 1‐step relation. The 1‐step relation is extended to (m‐1)‐step relation to calculate the degree of attainability of the same pair of attributes in the presence of m (all) attributes. The different levels of (m‐1)‐step relations generate several partitions of the attributes corresponding to multiple purposes in the multiple attribute decision‐making problems. The degree of fulfilment of the purposes in the alternatives are numerically derived by first taking weighted average of attributes within the equivalence classes of a partition and then aggregating the values corresponding to equivalence classes through ordered weighted averaging. The methodology is illustrated with a numerical example. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

In the field of eye tracking, scanpath analysis can reflect the sequential and temporal properties of the cognitive process. However, the advantages of scanpath analysis have not yet been utilized in the study of risky decision making. We explored the methodological applicability of scanpath analysis to test models of risky decision making by analyzing published data from the eye‐tracking studies of Su et al. (2013); Wang and Li (2012), and Sun, Rao, Zhou, and Li (2014). These studies used a proportion task, an outcome‐matched presentation condition, and a multiple‐play condition as the baseline for comparison with information search and processing in the risky decision‐making condition. We found that (i) the similarity scores of the intra‐conditions were significantly higher than those of the inter‐condition; (ii) the scanpaths of the two conditions were separable; and (iii) based on an inspection of typical trials, the patterns of the scanpaths differed between the two conditions. These findings suggest that scanpath analysis is reliable and valid for examining the process of risky decision making. In line with the findings of the three original studies, our results indicate that risky decision making is unlikely to be based on a weighting and summing process, as hypothesized by the family of expectation models. The findings highlight a new methodological direction for research on decision making. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

Copycats often choose brand names that mimic perceptual, conceptual, or both elements of leading brand names. Yet little is known about how perceptual and conceptual similarities of a copycat interact to affect consumers' evaluations, especially in logographic language systems (e.g., Chinese). Three laboratory experiments demonstrate that perceptual similarity alone leads to negative evaluations of copycat brand names; this negative effect, however, can be mitigated when conceptual similarity is added. The underlying mechanism for this effect can be traced to consumers' persuasion knowledge. Perceptual (vs. conceptual) similarity activates consumers' persuasion knowledge about the insincere motives of the copycat brand, which in turn shapes their brand evaluations. However, this effect can become less prominent when conceptual similarity is added because it alleviates use of persuasion knowledge, or when a consumer is in a happy mood because it neutralizes persuasion knowledge. These findings shed light on how different types of copycat strategies interact to affect copycat brand name evaluations and offer important implications for marketing practice.

The maximum cardinality subset selection problem requires finding the largest possible subset from a set of objects, such that one or more conditions are satisfied. An important extension of this problem is to extract multiple subsets, where the addition of one more object to a larger subset would always be preferred to increases in the size of one or more smaller subsets. We refer to this as the multiple subset maximum cardinality selection problem (MSMCSP). A recently published branch‐and‐bound algorithm solves the MSMCSP as a partitioning problem. Unfortunately, the computational requirement associated with the algorithm is often enormous, thus rendering the method infeasible from a practical standpoint. In this paper, we present an alternative approach that successively solves a series of binary integer linear programs to obtain a globally optimal solution to the MSMCSP. Computational comparisons of the methods using published similarity data for 45 food items reveal that the proposed sequential method is computationally far more efficient than the branch‐and‐bound approach.  相似文献

Abstract : This research examined how domestic consumers respond to an advertisement using brand popularity in a foreign market. By using structural equation modeling, it shows that the consumers’ response can change as a function of three characteristics of brand popularity in a foreign market: (a) expertise of foreign consumers, (b) similarity between domestic consumers and foreign consumers, and (c) animosity to a foreign country. Meanwhile, the similarity effect is found to be stronger for high‐preference heterogeneity than low‐preference heterogeneity. This research documents the importance of understanding the underlying mechanism to determine the effects of brand popularity in a foreign market on brand attitude and purchase intention.  相似文献
