The literature on quantum logic emphasizes that the algebraic structures involved with orthodox quantum mechanics are non distributive. In this paper we develop a particular algebraic structure, the quasi-lattice ( \mathfrakI{\mathfrak{I}}-lattice), which can be modeled by an algebraic structure built in quasi-set theory \mathfrakQ{\mathfrak{Q}} . This structure is non distributive and involve indiscernible elements. Thus we show that in taking into account indiscernibility as a primitive concept, the quasi-lattice that ‘naturally’ arises is non distributive.  相似文献

The authors investigated how anxiety influences the use of contextual information in the resolution of ambiguity. Participants heard ambiguous homophones (threat/neutral, positive/neural, and neutral/neutral) with related contextual information. State anxiety was manipulated experimentally. The interpretations of anxious participants were influenced by context to a greater extent than those of control participants. Some mood-incongruent effects were observed where anxious participants were more likely to adopt neutral interpretations of potentially threatening stimuli. Effects were observed in a spelling task (Experiments 1 and 2) and in a lexical decision task (Experiment 3), with supraliminal, and subliminal presentation of contextual cues, and with 2 different anxiety-induction procedures. Results show how anxiety affects both the content and the process of resolution of ambiguity.  相似文献

Recently, several theories of decision making and probability judgment have been proposed that take into account ambiguity (Einhorn and Hogarth, 1985; Gardenfors and Sahlin, 1982). However, none of these theories explains exactly what the psychological causes of ambiguity are or addresses the issue of whether ambiguity effects are rational. In this paper, we define ambiguity as the subjective experience of missing information relevant to a prediction. We show how this definition can explain why ambiguity affects decisions in the ways it does. We argue that there are a variety of rational reasons ambiguity affects probability judgments and choices in the ways it does. However, we argue that the ambiguity effect does not cast doubt on the claim that utility theory is a standard of rational choice. Rather, we suggest that the effect of ambiguity on decisions highlights the fact that utility theory, like any normative model of decision making only prescribes the optimal decision, given what one knows.  相似文献

词汇歧义是语言的普遍现象。在汉语中, 歧义词的种类繁多, 是少数民族学生汉语学习困难的重要原因之一。通过两个实验, 考察在不同加工时间条件下维吾尔族和汉族的大学生在汉语歧义词消解中的语境促进效应及抑制效应。结果发现, 两个民族的大学生均出现了语境促进效应, 但在短时加工条件下, 汉族大学生的语境促进效应显著大于维吾尔族大学生, 在长时加工条件下, 两个民族的大学生的语境促进效应并无显著差异。在短时加工条件下, 仅汉族大学生可以有效地抑制无关信息的干扰; 在长时加工条件下, 两个民族的大学生均可以有效地抑制无关信息的干扰。整个研究表明, 在汉语歧义词消解中, 随着加工时间增加, 维吾尔族大学生的语境促进效应和对无关信息的抑制均可以达到与汉族大学生相近的水平。  相似文献

In the present study, we examined how morphemic ambiguity is resolved using the visual-world paradigm. Participants were presented with Chinese bimorphemic words containing an ambiguous morpheme (analogous to the suffix -er in teacher and taller) and performed a visual search task. Their eye-movement patterns during target detection showed that (1) without a prior context, the dominant meaning of an ambiguous morpheme was more available than the subordinate one; (2) with a dominant-biased prior context, the subordinate meaning was still activated; and (3) a subordinate-biased prior context could inhibit the dominant interpretation. Therefore, both the frequency of the intended meaning and the prior contextual biases play a role in morphemic ambiguity resolution. The results are discussed with reference to models of ambiguity resolution and recent proposals of the graded nature of morphological effects.  相似文献

Models of lexical ambiguity resolution posit a role for context, but this construct has remained relatively undefined in the literature. The present study isolated two different forms of contextual constraint and examined how these sources of information might differentiate between a selective access and a reordered access model of ambiguity processing. Eye movements were monitored as participants read passages that contained either a balanced or a biased ambiguous word. The sentence containing the ambiguous word was held constant and instantiated either the subordinate meaning (Experiment 1) or the dominant meaning (Experiment 2) through the use of local context. These sentences were embedded in passages in which the topic was consistent, inconsistent, or neutral with respect to the meaning biased by the critical sentence. Experiment 1 provided evidence suggesting that the subordinate meaning of an ambiguous word was not selectively accessed even when sentence and discourse topic information biased that meaning. The data from Experiment 2 provided evidence that even the dominant meaning was not selectively accessed. These contextual sources of information were evaluated in terms of the roles they play in models of lexical ambiguity resolution.  相似文献

句法歧义消解主要是指人们在面临多种句法分析可能性的情况下,句法分析器抑制不正确的句法分析而选择正确句法分析的认知过程。研究表明,该过程受到工作记忆、认知控制能力、语言分布频率、语境、韵律等因素的影响。为有效说明人们是如何完成句法歧义消解的,研究者们建构了诸如花园路径模型、约束满意理论、弱交互作用句法分析理论等相关模型。另外,基于脑成像技术研究表明,左侧额下回、左侧颞叶后部、中部和前部在句法消歧任务中都有显著激活。未来研究当围绕着句法消歧中的语义效应、句法和词汇歧义消解机制的异同、句法消歧中抑制能力的效应等方面展开。  相似文献

Because conflicts between personal and professional values can interfere with ethical decision making, a goal of counselor education must be helping students reconcile such conflicts. This article describes one counselor educator's experience teaching ethical decision making and the effects on student learning. Growth was observed in increased tolerance for ambiguity, awareness of how values influenced decision making, use of multiple factors in decision making, and emphasis on the welfare of clients. Implications for teaching and future research directions are discussed.  相似文献

Words are considered semantically ambiguous if they have more than one meaning and can be used in multiple contexts. A number of recent studies have provided objective ambiguity measures by using a corpus-based approach and have demonstrated ambiguity advantages in both naming and lexical decision tasks. Although the predictive power of objective ambiguity measures has been examined in several alphabetic language systems, the effects in logographic languages remain unclear. Moreover, most ambiguity measures do not explicitly address how the various contexts associated with a given word relate to each other. To explore these issues, we computed the contextual diversity (Adelman, Brown, & Quesada, Psychological Science, 17; 814–823, 2006) and semantic ambiguity (Hoffman, Lambon Ralph, & Rogers, Behavior Research Methods, 45; 718–730, 2013) of traditional Chinese single-character words based on the Academia Sinica Balanced Corpus, where contextual diversity was used to evaluate the present semantic space. We then derived a novel ambiguity measure, namely semantic variability, by computing the distance properties of the distinct clusters grouped by the contexts that contained a given word. We demonstrated that semantic variability was superior to semantic diversity in accounting for the variance in naming response times, suggesting that considering the substructure of the various contexts associated with a given word can provide a relatively fine scale of ambiguity information for a word. All of the context and ambiguity measures for 2,418 Chinese single-character words are provided as supplementary materials.  相似文献

After performing such solitary decision making tasks as the Iowa Gambling Task (IGT) and the Game of Dice Task (GDT), we expected that changes will occur in Extraversion trait measured by a short Hungarian Big Five Inventory (BFI). We also hypothesized that ego-resiliency (Block, 2002)—a dimension measuring the ability to adapt to situational demands—will be linked to the magnitude of Extraversion change. After a pre-task measurement of the Big Five traits and ego-resiliency, participants (N = 93) completed the IGT and the GDT tasks. After each task, they filled out the BFI again. Pre- and post-task Big Five trait values showed significant differences. Participants reported lower post task scores on the Extraversion dimension and the magnitude of Extraversion change between pre- and post-task measurements correlated with ego-resiliency. The results highlight some short term effects of contextual factors influencing self-characterizations in BFI dimensions. Especially, individuals with high ego-resiliency give characteristically more introverted self-characterization after solitary tasks. The present results show an example of how the interplay between contextual factors and ego-resiliency can modify self-characterization within a very short period of time.  相似文献

Previous psycholinguistic research has shown that a variety of contextual factors can influence the interpretation of syntactically ambiguous structures, but psycholinguistic experimentation inherently does not allow for the investigation of the role that these factors play in natural (uncontrolled) language use. We use regression modeling in conjunction with data from the British National Corpus to measure the amount and specificity of the information available for disambiguation in natural language use. We examine the Direct Object/Sentential Complement ambiguity and the closely related issue of complementizer use in sentential complements, and find that both ambiguity resolution and complementizer use can be predicted from contextual information.  相似文献

Imagine Heidegger in a township. Imagine you are able to translate his concept of ‘care’ to ‘the people’. Would they agree that in their ordinary experience people care? I argue not and contend that, instead, they would choose the term ‘struggle’. I analyse experiential aspects of ordinary life in the context of the township, which involves a significant part of people around the world, in order to argue that, at least in such contexts, it is a more common experience for people to struggle than to care. In this way I hope to show how a phenomenological analysis of everyday life experience such as Heidegger's can contribute to the understanding of contextual issues, but also how a context can induce the introduction of new concepts of thinking.  相似文献

In this paper we discuss the use of quantum mechanics to model psychological experiments, starting by sharply contrasting the need of these models to use quantum mechanical nonlocality instead of contextuality. We argue that contextuality, in the form of quantum interference, is the only relevant quantum feature used. Nonlocality does not play a role in those models. Since contextuality is also present in classical models, we propose that classical systems be used to reproduce the quantum models used. We also discuss how classical interference in the brain may lead to contextual processes, and what neural mechanisms may account for it.  相似文献

采用眼动技术,通过两个实验,考察藏-汉读者阅读汉语歧义句时的歧义效应以及语境在句子歧义消解中的作用。结果发现:藏-汉读者在阅读汉语歧义句时存在歧义效应; 语境对歧义消解起促进作用,表现为,当语境置于歧义句之前或语境意义偏向歧义句主要意思时,藏-汉读者对歧义句的加工更容易。并且,歧义效应和语境促进效应贯穿于早期阶段到晚期阶段的整个句子加工过程。  相似文献

In his book Mind and World (1994), John McDowell defends the Kantian position that the content of experience is conceptual. Without this Kantian assumption, he argues, it would be impossible to understand how experience may rationally constrain thought. But McDowell's Kantianism is either false or empty, and his view of the relation between mind and world cannot be stated without transcending the bounds of sense. McDowell's arguments supporting the Kantian thesis, which are very different from Kant's arguments, essentially involve a fallacy of ambiguity. In order to understand how thought may be rationally constrained by experience we should become empiricists.  相似文献

Previous research has shown that overhearing an errant rumor—either from an adult or from peers—about an earlier experience can lead children to make detailed false reports. This study investigates the extent to which such accounts are driven by changes in children’s memory representations or merely social demands that encourage the reporting of rumored information. This was accomplished by (a) using a warning manipulation that eliminated social pressures to report an earlier heard rumor and (b) examining the qualitative characteristics of children’s false narratives of a rumored-but-nonexperienced event. Findings indicated that overheard rumors can induce sensory and contextual characteristics in memory that can lead children to develop genuine false beliefs in seeing rumored-but-nonexperienced occurrences. Such constructive tendencies were especially likely among 3- and 4-year-olds (relative to 5- and 6-year-olds) and when rumors were picked up from peers during natural social interactions (relative to when they were planted by an adult).  相似文献

近10年以来, 一些学者基于量子理论研究思想与方法探索出了量子决策模型。由于该模型独特的理论结构, 它可被用于解释传统决策理论所难以解释的问题, 尤其是个体在不确定情况下的决策行为。该模型解释了诸如分离效应、分类决策的干涉效应以及合取谬误等传统决策模型很难解释的问题, 研究者已经证实其中一种称为量子问题等式的决策模型可以精确地预测决策中的顺序效应。作为一个有助于分析心理学中决策现象的新研究领域, 量子决策模型具有深入研究的理论意义和实践意义。  相似文献

Quantum mechanics, and classical mechanics, are framework theories that incorporate many different concrete theories which in general cannot be arranged in a neat hierarchy, but discussion of ‘the ontology of quantum mechanics’ tends to proceed as if quantum mechanics were a single concrete theory, specifically the physics of nonrelativistically moving point particles interacting by long-range forces. I survey the problems this causes and make some suggestions for how a more physically realistic perspective ought to influence the metaphysics of quantum mechanics.
