左右结构单字词(2R词)中的部件和双字词(2C词)中的字都是构词成分。有研究表明,在词汇判断任务中,部件的相对位置影响2R词的识别,字的相对位置却不影响2C词的识别。在其他任务中,2R词中部件的相对位置信息似乎也是可以忽视的。
词是语义表征的基本单位。和启动词汇判断任务相比,启动语义归类任务可能更有利于测量启动刺激和目标刺激间的语义联系。我们采用启动语义归类任务对大学生进行了两项实验研究,并对同一目标词使用了三种启动刺激:和目标词所指事物同属一概念范畴的样例词(语义启动)、语义启动的逆序非词和目标词的逆序非词。
结果发现,不论2R词还是2C词,三种启动刺激对被试判断目标词所指事物是否有生命性的反应有显著性影响,而且,三种启动刺激在启动效应大小上没有显著性差异。这意味着,在激活有无生命概念表征的时候,指具体事物的单双字词有相似性。
结论是,在2R词和2C词识别的早期阶段,熟练读者对词及其构成成分语义信息的提取是同时进行的,构成成分的位置信息不重要。毕竟2R词和2C词结构成分的相对位置是固定的,因此未来需要探究2R词和2C词成分位置信息何时得以加工。 相似文献

加强医疗资源整合 发展医院优势学科 总被引:1,自引:1,他引:0
科学合理地实施医疗资源整合,是现代医院管理者要完成的重要课题。其主要形式有:成立技术协作组,设立独立专科,建立专科技术中心。医疗资源整合不是形式上的算术叠加,而是将管理理念与医院实际相结合,对医院人、财、物等进行有效地调整和组合,使其产生最大的综合效益。科学的论证、有力的政策机制和有效的管理手段是医疗资源整合成功的可靠保证。 相似文献

We argue that moral judgment studies currently conducted utilizing virtual reality (VR) devices must confront a dilemma as a result of how virtual environments are designed and how those environments are experienced. We first begin by describing the contexts present in paradigmatic cases of naturalistic moral judgments. We then compare these contexts to current traditional (vignette-based) and VR-based moral judgment research. We show that, contra to paradigmatic cases, vignette-based and VR-based moral judgment research often fails to accurately model the situational features of paradigmatic moral judgments. In particular, we compare and contrast six recent VR studies to support our view that only simulations high in context-realism and perspectival-fidelity can produce “virtually-real experiences.” After analyzing the constituents of a virtually-real experience, we go on to propose guidelines for the creation of VR studies. These guidelines serve two purposes. First, we aim to increase the ecological validity of such studies to advance our understanding of moral judgments. Second, we believe that such guidelines should inform how Institutional Review Boards assess VR research. We show that our guidelines are urgently needed, given the current lax review standards in place. 相似文献

在动作事件的再认记忆中,被试操作后的记忆成绩优于单纯的词语记忆(SPT效应)。人们认为操作促进了回想加工,而熟悉性是否对SPT效应起作用仍然存在分歧。研究采用无线索回忆再认范式,考察了信息提取失败时熟悉性对SPT效应的作用。结果显示:(1)SPT和VT两种编码都引发了稳定的无线索回忆再认效应(RWCR效应)。(2)与VT编码相比,SPT编码引发更强的熟悉性加工,表现出无线索回忆再认的记忆优势。上述结果表明,即使无法正确提取细节信息,在SPT编码中被试凭借熟悉性辨认的能力仍然高于VT编码。该结果从信息提取失败的视角为熟悉性对SPT效应的作用提供了更为直接的证据。 相似文献

Abstract: Six undergraduates were exposed to a fixed‐ratio schedule with an instruction to respond slowly and to a differential‐reinforcement‐of‐low‐rate schedule with an instruction to respond rapidly when a white circle was presented on a display monitor. When a yellow circle was presented, however, the subjects were exposed to the fixed‐ratio schedule with the instruction to respond rapidly and to the differential‐reinforcement‐of‐low‐rate schedule with the instruction to respond slowly. Following this, a fixed‐interval schedule was in effect during those stimuli and instructions. Under the white circle, response rates were higher with the instruction to respond slowly than with the instruction to respond rapidly during the fixed‐interval schedule. Such control by instructions was not observed under the yellow circle. A previous study examined establishment of novel instructional control by between‐subject comparisons and found that for three of four subjects ( Okouchi, 1999 ). In contrast, the present results demonstrate the instructional control through within‐subject comparisons for all six subjects. 相似文献

The paper presents an infinite hierarchy of sound and complete axiomatic systems for Two-Dimensional Modal Tense Logic with Historical Necessity, Agents and Acts. A main novelty of these logics is their capacity to represent formally (i) basic action-sentences asserting that such and such an act is performed/omitted by an agent, as well as (ii) causative action-sentences asserting that by performing/omitting a certain act, an agent causes that such and such a state-of-affairs is realized (e.g. comes about/ceases/remains/remains absent). We illustrate how the formal machinery of our systems can be used to reconstruct a number of interesting ideas in the Logic of Agency and Action that have been proposed by authors like von Wright, von Kutschera, Belnap and Segerberg. 相似文献

This study investigated the relationship between supervisor job experience and ratings of the importance of eight skill components for performing subordinates' jobs. When examining these correlations, statistical control was utilized to ensure that supervisor and subordinate characteristics confounded with supervisor job experience were not affecting hypothesized relationships. As predicted, there were statistically significant positive correlations between supervisor job experience and ratings on 6 of the 8 components. Also as predicted, controlling for the characteristics confounded with supervisor job experience made a substantial difference in results; 13 of the 16 correlations using statistical control significantly differed from correlations that did not. This illustrates that future research on SME characteristics should consider controlling variables confounded with the focal characteristic(s) under study in order to more thoroughly understand characteristic–rating relationships. Implications of these findings for research and practice are discussed and suggestions for future research are offered. 相似文献

This paper is a modification of Nicola Guarino and Christopher Welty's conception of the subsumption relation. Guarino and Welty require that that whether one property may subsume the other should depend on the modal metaproperties of those properties. I argue that the part of their account that concerns the metaproperty carrying a criterion of identity is essentially flawed. Subsequently, I propose to constrain the subsumption relation not, as Guarino and Welty require, by means of incompatible criteria of absolute identity but by means of incompatible criteria of relative identity. After discussing the benefits of applying relative identity in ontological investigations I provide a formal framework in which to prove a counterpart of the identity criteria constraint.This revised version was published online in October 2005 with corrections to the Cover Date. 相似文献
