Event-related potentials were measured to investigate the role of visual spatial attention mechanisms in conflict processing.
We suggested that a more difficult target selection leads to stronger attentional top-down control, thereby reducing the effects
of arising conflicts. This hypothesis was tested by varying the selection difficulty in a location negative priming (NP) paradigm.
The difficult task resulted in prolonged responses as compared to the easy task. A behavioral NP effect was only evident in
the easy task. Psychophysiologically the easy task was associated with reduced parietal N1, enhanced frontocentral N2 and
N2pc components and a prolonged P3 latency for the conflict as compared to the control condition. The N2pc effect was also
obvious in the difficult task. Additionally frontocentral N2 amplitudes increased and latencies of N2pc and P3 were delayed
compared to the easy task. The differences at frontocentral and parietal electrodes are consistent with previous studies ascribing
activity in the prefrontal and parietal cortex as the source of top-down attentional control. Thus, we propose that stronger
cognitive control is involved in the difficult task, resulting in a reduced behavioral NP conflict. 相似文献

Jerry is a personal essay in which the author examines his relationship with a friend of the past 11 years. The author draws
parallels between their outwardly very different lives and suggests how personal love and spiritual grace have unexpectedly
crept in to influence both of them. 相似文献

Previous studies have shown that children retreat from argument-structure overgeneralization errors (e.g., * Don't giggle me ) by inferring that frequently encountered verbs are unlikely to be grammatical in unattested constructions, and by making use of syntax-semantics correspondences (e.g., verbs denoting internally caused actions such as giggling cannot normally be used causatively). The present study tested a new account based on a unitary learning mechanism that combines both of these processes. Seventy-two participants (ages 5–6, 9–10, and adults) rated overgeneralization errors with higher (* The funny man's joke giggled Bart ) and lower (* The funny man giggled Bart ) degrees of direct external causation. The errors with more-direct causation were rated as less unacceptable than those with less-direct causation. This finding is consistent with the new account, under which children acquire—in an incremental and probabilistic fashion—the meaning of particular constructions (e.g., transitive causative = direct external causation) and particular verbs, rejecting generalizations where the incompatibility between the two is too great. 相似文献

Several driving simulators have been developed which range in complexity from PC based driving tasks to advanced "real world" simulators. The AusEd driving simulator is a PC based task, which was designed to be conducive to and test for driver fatigue. This paper describes the AusEd driving simulator in detail, including the technical requirements, hardware, screen and file outputs, and analysis software. Some aspects of the test are standardized, while others can be modified to suit the experimental situation. The AusEd driving simulator is sensitive to performance decrement from driver fatigue in the laboratory setting, potentially making it useful as a laboratory or office based test for driver fatigue risk management. However, more research is still needed to correlate laboratory based simulator performance with real world driving performance and outcomes. 相似文献

Coloring only a single letter in the Stroop task can result in a reduction or elimination of Stroop interference. The present experiments were designed to test whether this modulation of Stroop interference occurs at all letter positions. Specifically, we investigated whether Stroop interference was reduced when the colored letter occupied the optimal viewing position (OVP). The experiments show that Stroop interference is not reduced at the OVP (Experiment 1) and that Stroop interference at the OVP is significantly greater than at other letter positions (Experiments 1 and 2). This finding has important theoretical and methodological consequences for studies of automatic processing in visual word recognition. 相似文献

In this paper, I defend the claim that an object can have a property only if it exists from two arguments, both of which turn
on how to understand Plantinga’s notion of the α-transform of a property.

For years, the authors of the best-selling guide to India, Lonely Planet, has shaped the perspectives of many travellers. This article considers how religion is constructed as a category and how it is made relevant to travellers. I argue that ‘religion’ comes in two versions, one pertaining to the Indian hosts and one to travellers. Religion is based on tradition, faith and historical institutions, whose members, rituals and sacred sites are of interest to travellers. Spirituality has to do with the personal development of travellers and is exclusively referred to as philosophy. 相似文献

当前大多数融合反应时的IRT模型仅适用于0-1评分数据资料,极大的限制了IRT反应时模型在实际中的应用。本文在传统的二级计分反应时IRT模型基础上,拟开发一种多级评分反应时模型。在层次建模框架下,分别采用拓广分部评分模型(GPCM)和对数正态模型构建融合反应时的多级评分IRT模型(本文记为JRT-GPCM),并采用全息贝叶斯MCMC算法实现新模型的参数估计。为验证新开发的JRT-GPCM模型的可行性及其在实践中的应用,本文开展了两项研究:研究1为模拟实验研究,研究2为新模型在大五人格-神经质分量表中的应用。研究1结果表明,JRT-GPCM模型的估计精度较高,且具有较好的稳健性。研究2表明,被试的潜在特质与作答速度具有一定的正相关,且本研究结果支持Ferrando和Lorenzo-Seva(2007)提出的“距离-困难度假设”,即当被试的潜在特质与项目的难度阈限距离越远,那么被试会花费更多的时间对项目进行作答。总之,本研究为拓展反应时信息在心理测量及教育中的应用提供新的方法支持。 相似文献

The Continuity Test is the principle that a proposed distribution of resources is wrong if it treats someone as disadvantaged when they don't see it that way themselves, for example by offering compensation for features that they do not themselves regard as handicaps. This principle — which is most prominently developed in Ronald Dworkin's defence of his theory of distributive justice — is an attractive one for a liberal to endorse as part of her theory of distributive justice and disadvantage. In this article, I play out some of its implications, and show that in its basic form the Continuity Test is inconsistent. It relies on a tacit commitment to the protection of autonomy, understood to consist in an agent deciding for herself what is valuable and living her life in accordance with that decision. A contradiction arises when we consider factors which are putatively disadvantaging by dint of threatening individual autonomy construed in this way. I argue that the problem can be resolved by embracing a more explicit commitment to the protection (and perhaps promotion) of individual autonomy. This implies a constrained version of the Continuity Test, thereby salvaging most of the intuitions which lead people to endorse the Test. It also gives us the wherewithal to sketch an interesting and novel theory of distributive justice, with individual autonomy at its core. 相似文献
