In this article, we sought to isolate the processing demands of combining the concepts of modifier‐noun phrases from those of other language comprehension processes. Probe reaction time (RT) was used as an indication of the processing resources required for combining concepts. Phrase frequency (as measured by Google hit rates) was used as a metric of the degree of conceptual combination required for each phrase. Participants were asked to interpret modifier‐noun phrases using a sense‐nonsense decision (Experiment 1) and a phrase meaning access task (Experiment 2). Experiment 2 also used a lexical decision task to activate the word's individual meanings. Regression analyses for both experiments indicated that phrase frequency (indicating novelty) predicts a significant portion of the probe RT variance, such that low‐frequency phrases required more processing resources than high‐frequency phrases, when controlling for associative strength, word frequency, letter length, and lexical‐semantic activation. Overall, this study indicates that conceptual combination requires processing resources beyond those of other language processes. 相似文献

A reaction-time measure of attention was employed during five segments of a simultaneous dart throw: premovement decision, immediately after recoil was begun, maximum recoil, immediately after forward movement was begun, and after release of the dart. Reaction time was significantly longer when the stimulus was presented during the first or second segment than during later segments. Reaction time during premovement was not consistently greater than that immediately after movement was begun, indicating that information is being sampled at a high rate after movement commences. It appears that monitoring of proprioceptive feedback after movement has begun, and initiation of corrective submovements, is necessary for skillful performance of dart throwing. 相似文献

空间再定向是指迷失方向的个体在空间中重新确定自己方位并找回迷失方向前丢失或被隐藏物体的能力.几何模块理论、适应性结合理论和视觉图像匹配理论都能够对儿童空间再定向做出一定解释,但三者之间互不相容,并存在局限:解释不了语言对整合几何和非几何信息的影响、环境空间大小和参照系选择对再定向的影响以及空间再定向中性别差异的现象.今后研究应注意实验的生态效应、空间条件的规则性、几何信息的直接性与间接性以及对三个理论的整合. 相似文献

各种心理调查、心理实验中, 数据的缺失随处可见。由于数据缺失, 给概化理论分析非平衡数据的方差分量带来一系列问题。基于概化理论框架下, 运用Matlab 7.0软件, 自编程序模拟产生随机双面交叉设计p×i×r缺失数据, 比较和探讨公式法、REML法、拆分法和MCMC法在估计各个方差分量上的性能优劣。结果表明:(1) MCMC方法估计随机双面交叉设计p×i×r缺失数据方差分量, 较其它3种方法表现出更强的优势; (2) 题目和评分者是缺失数据方差分量估计重要的影响因素。 相似文献

Theories of embodied cognition hold that the conceptual system uses perceptual simulations for the purposes of representation. A strong prediction is that perceptual phenomena should emerge in conceptual processing, and, in support, previous research has shown that switching modalities from one trial to the next incurs a processing cost during conceptual tasks. However, to date, such research has been limited by its reliance on the retrieval of familiar concepts. We therefore examined concept creation by asking participants to interpret modality-specific compound phrases (i.e., conceptual combinations). Results show that modality switching costs emerge during the creation of new conceptual entities: People are slower to simulate a novel concept (e.g., auditory jingling onion) when their attention has already been engaged by a different modality in simulating a familiar concept (e.g., visual shiny penny). Furthermore, these costs cannot be accounted for by linguistic factors alone. Rather, our findings support the embodied view that concept creation, as well as retrieval, requires situated perceptual simulation. 相似文献

Raising the quality of life for each individual has been approved by Saeima (Parliament) of Latvia as the basic goal for development
of the country. Several valuable factors – welfare, security, sustainability – forms human's quality of life in the broader
sense of this concept. As a multi-dimensional issue quality of life in Latvia's case depends on a series of closely linked
both internal and external domains. Approved growth model for Latvia defines that the main resource to achieve increasing
quality of life is the collective knowledge and wisdom of Latvia's inhabitants, and the ability of each individual to make
use of this resource. General inclusion of all residents of the country becomes a principal precondition for improvement of
the quality of life. In achieving our goal we must make use of coordinated and balanced development of each domain of quality
of life, taking into account the unity of activities and following the boundary spanning principle. Practical activities have
been started to implement the model. 相似文献

包含评分者侧面的测验通常不符合任意一种概化理论设计,因此从概化理论的角度来看这类测验下的数据应属于缺失数据,而决定缺失结构的就是测验的评分方案。用R软件模拟出三种评分方案下的数据,并比较传统法、评价法和拆分法在各评分方案下的估计效果,结果表明:(1)传统法估计准确性较差;(2)评分者一致性较高时,适宜用评价法进行估计;(3)拆分法的估计结果最准确,仅在固定评分者评分方案下需注意评分者与考生数量之比,该比值小于等于0.0047 时估计结果较为准确。 相似文献

Panpsychism claims that each fundamental entity is conscious, but then faces the problem of how such entities combine to make up our ordinary consciousness. In this paper, I show how panpsychism can avoid this so-called combination problem by taking seriously plural collective properties at the fundamental level. 相似文献

We investigated the extent to which a complex finger sequence impacts on hand switching costs in a sequential action. Response component latencies (premotor, motor, and movement) were compared in no-switch (same finger performed the action of pressing and reaching) and switch conditions (pressing with one finger and completing the reaching action with the homologous finger from the other hand). Results showed that the switch condition presented longer latency for premotor and movement components. For the motor component, however, switch condition was faster. This expands the previous literature investigating switching costs using simple finger movements in more complex tasks. A mechanical explanation of the interplay between response subcomponents is provided to explain the inversion of response pattern for the motor component. 相似文献

核苷类似物治疗慢性乙型肝炎中的耐药及治疗决策 总被引:1,自引:0,他引:1
尽管核苷类药物做为慢性乙型肝炎抗病毒治疗的一线用药广泛应用于临床多年,但随着用药时间的延长,治疗过程中出现了耐药这个极具挑战性的问题。核苷类药物的联合治疗或许能阻止或延缓耐药发生。 相似文献
