探讨状态焦虑对回溯式时距判断的影响, 并检测记忆偏向与认知评价在其中的中介和调节作用。实验1招募大学生60人, 随机分为高、低状态焦虑组, 采用情绪诱导程序诱导高、低状态焦虑; 采用口头估计任务测量回溯式时距判断, 考察高、低状态焦虑诱导后的回溯式时距判断差异。实验2在实验1的基础上, 招募大学生60人, 增加自由回忆任务测量记忆偏向, 考察状态焦虑对回溯式时距判断的影响中记忆偏向的中介作用。实验3在实验1和实验2的基础上, 招募大学生90人, 增加视觉模拟心境量表测量认知评价, 考察状态焦虑对回溯式时距判断的影响, 并检测认知评价与记忆偏向在其中的作用。结果发现:(1)在回溯式时距判断中, 高状态焦虑比低状态焦虑更高估时距; (2)在状态焦虑对回溯式时距判断的影响中, 记忆偏向具有中介作用; (3)在状态焦虑对回溯式时距判断的影响中, 认知评价和记忆偏向存在有调节的中介作用:只有当认知评价得分较低时, 即对于认为焦虑对身体健康有害程度较低的个体而言, 在状态焦虑影响回溯式时距判断中, 记忆偏向具有完全中介作用, 即状态焦虑只通过记忆偏向影响回溯式时距判断。研究结果揭示了焦虑个体回溯式时距判断的内部过程, 验证了注意闸门模型中有关用于计时的记忆资源越多对于时距越高估的假设, 丰富了焦虑通过记忆偏向影响回溯式时距判断的解释视角, 为通过调整认知评价改善焦虑个体时距偏差提供了重要参考。  相似文献

This paper examines the effect of uncertainty and inconsistency on the judgment of human performance. The results indicate that the effect of inconsistency on judgment is not mediated by subjective uncertainty. We find that both the level and the extremity of judgment decrease with uncertainty. These effects are explained, respectively, by uncertainty aversion and by regressiveness. We also find that both the level and the extremity of judgment of human performance increase with inconsistency. These effects are explained by reliance on integration rules in which judgment is based primarily on some aspects of the information, while other aspects are, to some extent, ignored.  相似文献

The present study investigates how individuals distribute their attentional resources between a prospective memory task and an ongoing task. Therefore, metacognitive expectations about the attentional demands of the prospective-memory task were manipulated while the factual demands were held constant. In Experiments 1a and 1b, we found attentional costs from a prospective-memory task with low factual demands to be significantly reduced when information about the low to-be-expected demands were provided, while prospective-memory performance remained largely unaffected. In Experiment 2, attentional monitoring in a more demanding prospective-memory task also varied with information about the to-be-expected demands (high vs. low) and again there were no equivalent changes in prospective-memory performance. These findings suggest that attention–allocation strategies of prospective memory rely on metacognitive expectations about prospective-memory task demands. Furthermore, the results suggest that attentional monitoring is only functional for prospective memory to the extent to which anticipated task demands reflect objective task demands.  相似文献

The role of the right posterior parietal cortex in temporal order judgment   总被引:1,自引:0,他引:1  
Woo SH  Kim KH  Lee KM 《Brain and cognition》2009,69(2):337-343
Perceived order of two consecutive stimuli may not correspond to the order of their physical onsets. Such a disagreement presumably results from a difference in the speed of stimulus processing toward central decision mechanisms. Since previous evidence suggests that the right posterior parietal cortex (PPC) plays a role in modulating the processing speed of a visual target, we applied single-pulse TMS over the region in 14 normal subjects, while they judged the temporal order of two consecutive visual stimuli. Stimulus-onset-asynchrony (SOA) randomly varied between -100 and 100 ms in 20-ms steps (with a positive SOA when a target appeared on the right hemi-field before the other on the left), and a point of subjective simultaneity was measured for individual subjects. TMS stimulation was time-locked at 50, 100, 150, and 200 ms after the onset of the first stimulus, and results in trials with TMS on right PPC were compared with those in trials without TMS. TMS over the right PPC delayed the detection of a visual target in the contralateral, i.e., left hemi-field by 24 (+/-7 SE) ms and 16 (+/-4 SE) ms, when the stimulation was given at 50 and 100 ms after the first target onset. In contrast, TMS on the left PPC was not effective. These results show that the right PPC is important in a timely detection of a target appearing on the left visual field, especially in competition with another target simultaneously appearing in the opposite field.  相似文献

Stimulus contrast and duration effects on visual temporal integration and order judgment were examined in a unified paradigm. Stimulus onset asynchrony was governed by the duration of the first stimulus in Experiment 1, and by the interstimulus interval in Experiment 2. In Experiment 1, integration and order uncertainty increased when a low contrast stimulus followed a high contrast stimulus, but only when the second stimulus was 20 or 30 ms. At 10 ms duration of the second stimulus, integration and uncertainty decreased. Temporal order judgments at all durations of the second stimulus were better for a low contrast stimulus following a high contrast one. By contrast, in Experiment 2, a low contrast stimulus following a high contrast stimulus consistently produced higher integration rates, order uncertainty, and lower order accuracy. Contrast and duration thus interacted, breaking correspondence between integration and order perception. The results are interpreted in a tentative conceptual framework.  相似文献

Abstract:  This paper proposed two types of fuzzy set models for ambiguous comparative judgments, which did not always hold transitivity and comparability properties. The first type of model was a fuzzy theoretical extension of the additive difference model for preference that was used to explain ambiguous preference strength. The second was a fuzzy logic model for explaining ambiguous preference in which preference strength was bounded, such as a probability measure. In both models, multi-attribute weighting parameters and all attribute values were assumed to be asymmetric fuzzy L-R numbers. For each model, a method of parameter estimation using fuzzy regression analysis was proposed. Numerical examples were also provided for comparison. Finally, the theoretical and practical implications of the proposed models were discussed.  相似文献

注意一直是时间知觉研究的一个重要问题。本文综述了研究已经取得一些较为一致的结果:在双任务程序中对时间任务的注意越多,时距估计越准确;在单一任务中对目标刺激的时间属性注意越多,对该刺激的持续时距估计越准确;在时间导向任务中,个体可以有效地、主动把注意导向未来的某段时距,那么将对出现在那个时刻的刺激做出更好的反应。最后,讨论了现有研究中存在的、以及今后研究中需要着重考虑的问题。  相似文献

Body dissatisfaction and adolescent self-esteem: prospective findings   总被引:1,自引:3,他引:1  
Tiggemann M 《Body image》2005,2(2):129-135
The aim of the study was to investigate prospectively the direction of the relationship between adolescent girls’ body dissatisfaction and self-esteem. Participants were 242 female high school students who completed questionnaires at two points in time, separated by 2 years. The questionnaire contained measures of weight (BMI), body dissatisfaction (perceived overweight, figure dissatisfaction, weight satisfaction) and self-esteem. Initial body dissatisfaction predicted self-esteem at Time 1 and Time 2, and initial self-esteem predicted body dissatisfaction at Time 1 and Time 2. However, linear panel analysis (regression analyses controlling for Time 1 variables) found that aspects of Time 1 weight and body dissatisfaction predicted change in self-esteem, but not vice versa. It was concluded that young girls with heavier actual weight and perceptions of being overweight were particularly vulnerable to developing low self-esteem.  相似文献

We explored the nature of focal versus nonfocal event-based prospective memory retrieval. In the context of a lexical decision task, people received an intention to respond to a single word (focal) in one condition and to a category label (nonfocal) for the other condition. Participants experienced both conditions, and their order was manipulated. The focal instruction condition was a single word presented multiple times. In Experiment 1, the stimuli in the nonfocal condition were different exemplars from a category, each presented once. In the nonfocal condition retrieval was poorer and reaction times were slower during the ongoing task as compared to the focal condition, replicating prior findings. In Experiment 2, the stimulus in the nonfocal condition was a single category exemplar repeated multiple times. When this single-exemplar nonfocal condition followed in time the single-item focal condition, focal versus nonfocal performance was virtually indistinguishable. These results demonstrate that people can modify their stimulus processing and expectations in event-based prospective memory tasks based on experience with the nature of prospective cues and with the ongoing task.  相似文献

To evaluate the extent to which the models of moral judgment advanced by Kohlberg (1984) and by Gilligan (1982, 1988) are able to account for real-life moral judgment, we investigated the relation of sex and type of moral dilemma to moral stage and moral orientation. Eighty young adult men and women made moral judgments about two hypothetical Kohlberg dilemmas, two real-life antisocial dilemmas, and two real-life prosocial dilemmas. We failed to find any sex differences in moral judgment. Moral stage and moral orientation varied across the three types of dilemma. Kohlberg's dilemmas pulled for justice-oriented Stage 4 moral judgments, real-life prosocial dilemmas pulled for care-oriented Stage 3 moral judgments, and real-life antisocial dilemmas pulled for justice-oriented Stage 2 moral judgments. The content of moral judgments was related to their structure. There was a positive relation between stage of moral judgment on Kohlberg dilemmas and on real-life dilemmas. The implications of these findings for a new, more interactional, model of real-life moral judgment are discussed.  相似文献

It is known that concurrent non-temporal tasks shorten reproduced temporal durations in prospective duration judgments. Two experiments were carried out, one comparing a concurrent temporal task to a minimally demanding concurrent task (Experiment 1) and one comparing an executive concurrent (Simon) task with a less demanding non-executive concurrent task (Experiment 2). An effect of the concurrent task type on temporal reproductions was found. Furthermore, a duration length effect was found, where longer durations were underestimated more than shorter durations. This effect tended to be stronger for the experiments that included a concurrent task that demanded high attention.  相似文献

透镜模型强调线索的有效性是人格判断准确的重要条件。已有研究表明, 文字信息, 语音内容, 面孔图片, 反映不同情境的视频片段以及面对面交流涉及的言语、非言语信息在人格判断过程中发挥着重要作用。另一方面, 网络背景下常规的文字、视频信息等同样能够有效反映个体的人格特质, 而与人格特质密切相关的网络语言、表情的使用, 状态更新与点赞等特殊线索的有效性也值得深入探究。未来对人格判断线索的研究应加强现实生活情境以提高研究的生态效度, 考虑不同线索间的相互比较以考察线索有效性的适用条件, 深入探究网络情境中个体行为线索的有效性。  相似文献

This work investigates how we process and represent event duration in on-line language comprehension. Specifically, it examines how events of different duration are processed and what type of knowledge underlies their representations. Studies 1–4 examined verbs and phrases in different contexts. They showed that durative events took longer to process than non-durative events and that the duration attributed to the stimulus events correlated with on-line processing times. Studies 5 and 6 indicated that durative events occur in semantically more diverse contexts and elicit semantically more diverse associations than non-durative events. Semantic and contextual diversity also correlated with attributed durations and processing times. Results indicate that (a) event-specific durations are computed on-line from multiple unfolding cues, (b) processing cost and duration representations emerge from semantic and contextual diversity reflecting our experience, and (c) key components of duration representations may be situation-specific knowledge of causal and contingency relations between events.  相似文献

The influence of hierarchy on probability judgment   总被引:6,自引:0,他引:6  
Lagnado DA  Shanks DR 《Cognition》2003,89(2):157-178
Consider the task of predicting which soccer team will win the next World Cup. The bookmakers may judge Brazil to be the team most likely to win, but also judge it most likely that a European rather than a Latin American team will win. This is an example of a non-aligned hierarchy structure: the most probable event at the subordinate level (Brazil wins) appears to be inconsistent with the most probable event at the superordinate level (a European team wins). In this paper we exploit such structures to investigate how people make predictions based on uncertain hierarchical knowledge. We distinguish between aligned and non-aligned environments, and conjecture that people assume alignment. Participants were exposed to a non-aligned training set in which the most probable superordinate category predicted one outcome, whereas the most probable subordinate category predicted a different outcome. In the test phase participants allowed their initial probability judgments about category membership to shift their final ratings of the probability of the outcome, even though all judgments were made on the basis of the same statistical data. In effect people were primed to focus on the most likely path in an inference tree, and neglect alternative paths. These results highlight the importance of the level at which statistical data are represented, and suggest that when faced with hierarchical inference problems people adopt a simplifying heuristic that assumes alignment.  相似文献

This paper examines (a) whether people are less accurate in judging choice time as choice tasks involve more choice options, more choice information, or a combination of both and (b) whether people with a higher tendency to look for the best option in choice making (maximizers) have less accurate duration judgments of choice time as compared to people who are more easily settling for a choice outcome that is satisfactory (satisficers). A multilevel analysis is used to explore the relationships of interest using data collected through a series of choice tasks. In general, the results suggest that people seem to misjudge time durations when making choices. Moreover, empirical evidence demonstrates that people with an outspoken tendency to maximize in choice making do not differ significantly in estimating choice time accurately as compared to people who experience almost no need to maximize.  相似文献

Perceptual grouping is crucial to distinguish objects from their background. Recent studies have shown that observers can detect an object that does not have any unique qualities other than unique temporal properties. A crucial question is whether focused attention is needed for this type of grouping. In two visual search experiments, we show that searching for an object defined by temporal grouping can occur in parallel. These findings suggest that focused attention is not needed for temporal grouping to occur. It is proposed that temporal grouping may occur because the neurons representing the changing object elements adopt firing frequencies that cause the visual system to bind these elements together without the need for focused attention.  相似文献

We investigated the role of honour concerns in mediating the effect of nationality and gender on the reported intensity of anger and shame in reaction to insult vignettes. Spain, an honour culture, and The Netherlands, where honour is of less central significance, were selected for comparison. A total of 260 (125 Dutch, 135 Spanish) persons participated in the research. Participants completed a measure of honour concerns and answered questions about emotional reactions of anger and shame to vignettes depicting insults in which type of threat was manipulated. It was found that Spanish participants responded especially intensely to insults that threaten family honour, and that this effect of nationality on emotional reactions to threats to family honour was mediated by individual differences in concern for family honour.  相似文献

Exploring emotions, in terms of their evolutionary origin; their basic neurobiological substratum, and their functional significance in autonomous agents, we propose a model of minimal functionality of emotions. Our aim is to provide a naturalized explanation - mostly based on an interactivist model of emergent representation and appraisal theory of emotions - concerning basic aesthetic emotions in the formation of aesthetic judgment. We suggest two processes the Cognitive Variables Subsystem (CVS) which is fundamental for the accomplishment of the function of heuristic learning; and Aesthetic Appraisal Subsystem (AAS) which primarily affects the elicitation of aesthetic emotional meanings. These two subsystems (CVS and AAS) are organizationally connected and affect the action readiness of the autonomous agent. More specifically, we consider the emotional outcome of these two subsystems as a functional indication that strengthens or weakens the anticipation for the resolution of the dynamic uncertainty that emerges in the particular interaction.  相似文献

Mou Zongsan incorrectly uses Kant’s practical reason to interpret Confucianism. The saying that “what is it that we have in common in our minds? It is the li 理 (principles) and the yi 义 (righteousness)” reveals how Mencius explains the origin of li and yi through a theory of common sense. In “the li and the yi please our minds, just as the flesh of beef and mutton and pork please our mouths,” “please” is used twice, proving aesthetic judgment is necessary to understanding Mencius. An analysis of Zhu Xi and Wang Yangming’s ideas will show that Confucianism should be interpreted by appealing to aesthetic judgment, and a discussion of Kant’s theory of judgment and Gadamer’s critique of Kant’s theory will support the same point. The conclusion is that Chinese moral philosophy should be interpreted through aesthetic judgment.  相似文献
