双加工理论认为熟悉性和回想是情景记忆的两个独立过程,其重要证据是ERP研究中FN400和LPC可以分别指示熟悉性和回想。但也有研究证明FN400是概念启动和熟悉性共同作用的结果,而LPC也不能准确的反映回想加工,因此,将其作为双加工理论证据的可靠性需进一步讨论。未来需进一步明确概念启动和熟悉性影响FN400的前提条件,并在提高生态效度和控制额外变量的同时明晰LPC的指向性,同时探究熟悉性和回想在再认过程中的具体作用方式。 相似文献

不断加剧的经济不平等问题对个体和社会有着巨大危害,然而人们对经济不平等却有着较高的容忍性。基于个体心理的研究证据,本文提出认知和动机双重路径模型来解释个体容忍和支持经济不平等问题。在认知路径上,个体倾向于低估当前社会的经济不平等程度和将经济不平等评价为公平的;在动机路径上,个体预期经济不平等将带来自我利益的增加。未来研究应进一步整合多重心理机制间的关系,并探索有效干预手段以增加人们对减少经济不平等的支持。 相似文献

为了研究眼跳的双相调节理论是否适用于人类的视觉系统,本研究测量了人类被试对分别呈现在三种眼跳时间段(基线、眼跳抑制和眼跳增强)内的光栅的朝向辨别准确率。研究发现:相对于光栅呈现在基线时间段内,被试对呈现在抑制(或增强)时间段内的光栅的朝向辨别准确率显著地更低(或更高)(实验1);另外,只有使用低或中等空间频率光栅作为测试刺激时,才有这种双相调节作用(实验2)。这些结果表明:人类的视觉系统在眼跳过程中存在双相调节机制,并且这种双相调节机制具有刺激选择性。 相似文献

This article examines the life stories of two young Polish women who have faced severe marginalization and homelessness. The main aim of this article is to investigate how the notions of (in)visibility and (im)mobility are shaping participants' everyday lives and life stories they tell. Using concepts drawn from social sciences, as well as cultural and literary studies, this article attempts to reconstruct the narrative frameworks of their life stories. Marzena's story is a non-linear collection of adventures reminiscent of a picaresque novel, but with fractured agency, which leaves her powerless and restlessly moving around the city. Angelika, on the other hand, is trapped in a two-room dilapidated house with no running water, located in a rural part of Poland. Her narrative resembles a telenovela with melodramatic plot twists, romance and hard-to-believe revelations about the narrator's true self; further, it is a purposeful journey in search for happiness and fortune. Surprisingly, Marzena's mobility makes it unlikely for her to overcome homelessness, while the stranded Angelika finds the resilience necessary to improve her life. The proposed analysis contributes to a deeper understanding of women's experiences of homelessness and demonstrates the need to regard housing exclusion also as a biographical process. 相似文献

A screening decision is about whether a candidate fails to meet a decision maker's criteria and must be rejected, or whether it meets the criteria and can be accepted. Image theory contends that screening decisions are based on a simple, noncompensatory process that focuses solely upon the candidate's negative attributes. This contention has received empirical support in a job screening context in which students role-played a hypothetical person seeking a job. But how robust is image theory's prediction? The present work was done in the context of professional auditors screening prospective clients. The client screening context is a particularly interesting setting to test the implications of image theory. If auditors reject clients with negative attributes, as predicted by image theory, this will indicate that some clients are being denied access to a socially useful service. Further, auditors can accept prospective clients with negative attributes and simply adjust the audit plan and fees to compensate for the client's riskiness. Thus, it is not clear that the preliminary findings obtained in a job screening context will generalize to the audit context. On the other hand, results consistent with the image theory prediction would suggest a robust theory. Even in the client screening context, where auditors used their own criteria to screen prospective clients, we found overwhelming support for image theory's view of screening. The results indicate the potential payoffs of image theory as a robust framework to address audit and other substantive problems. Implications of a noncompensatory, negative oriented, client screening strategy are discussed. 相似文献

An explanation-approach within the frame of a universal and integrating theory of aggression is favored for understanding the effects of exposure to violence. Kornadt's Motivation Theory of Aggression is used to generate several hypotheses concerning the effects of aggressive movies on a viewer's expectancy-value-cognitions and these are tested in an experiment. The experiment suggests that aggressive stimulation is able to change aggression-related expectancy-value-cognitions in an aggression-facilitating direction. Based on these results, an attempt is made to explain increases in the aggression of viewers in terms of the Motivation Theory of Aggression. © 1993 Wiley-Liss, Inc. 相似文献

Research indicates that selecting a strategy to best exploit a new technology is a complex decision-making process. The task involves making a series of decisions with multiple alternatives, each to be evaluated by multiple criteria whose values have high levels of uncertainty. This paper presents a methodology for modelling a new technology decision using decision trees and an optimizing algorithm. A problem of a mining company considering the adoption of new technology is used to illustrate the decision-making task and modelling methodology. A numerical solution to the case demonstrates the potential of the optimizing technique in strategy selection. 相似文献

Preferences are often represented in terms of a function, in the deterministic case as well as in the probabilistic case. In the present paper we develop a new numerical representation of preference structures for which the strict preference relation (P) is without circuit but not necessarily transitive. Moreover, we investigate the consequences of the representation for the usual preference structures. In particular, we propose new formulations for the numerical representation of the interval order structure. 相似文献
