Cancellation tests have been widely used in clinical practice and in research to evaluate visuospatial attention, visual scanning patterns, and neglect problems. The aim of the present work is to present a visualized interface for the visuospatial attentional assessment system that can be employed to monitor and analyze attention performance and the search strategies used during visuospatial processing of target cancellation. We introduce a pattern identification mechanism for visual search patterns and report our findings from examining the visual search performance and patterns. We also present a comparison of results across various cancellation tests and age groups. The present study demonstrates that our system can obtain more processing data about spatiotemporal features of visual search than can conventional tests. 相似文献

In the present article, a new software is introduced that allows the recording and analyzing of eye- and mouse-tracking data
from slideshow-based experiments in parallel. The Open Gaze and Mouse Analyzer (OGAMA) is written in C#.NET and has been released
as an open-source project. Its main features include slide-show design, the recording of gaze and mouse data, database-driven
preprocessing and filtering of gaze and mouse data, the creation of attention maps, areas-of-interest definition, and replay.
Eyetracking and/or presentation soft- and hardware recordings in ASCII format can be imported. Data output is provided that
can be used directly with different statistical software packages. Because it is open source, one can easily adapt it to suit
one’s needs. 相似文献

公共领域中的集群效能研究述评 总被引:1,自引:0,他引:1
公共领域中的集群效能是指公众通过分享所在地区的公共信任和社会凝聚力, 从而对于共同努力实现所在地区特定目标的一种集体信念和预期。公共领域中的集群效能有其独特的测量方法和研究结论, 集群效能的相关前因变量可以分为社会认同、社会经济地位和社会参与, 集群效能的相关影响作用研究可以分为公共安全、政治行为、公共卫生三个领域内的研究。文章最后指出未来在公共领域中集群效能研究有必要加强作用机制、动态变化等方面的探讨。 相似文献

进化动机影响社会认知的研究关注社会认知的起源、机能及影响。进化动机影响社会认知的一般特点有(1)特殊性, 如成功地解决求偶问题的机制不能用来解决身体危险有关的问题, (2)灵活性, 如不同类别的环境线索自动地激活与线索类别有关的社会信息。借用传统的社会认知研究方法, 研究者发现特定的线索会启动相应的进化动机(如面孔吸引力启动人们的求偶动机), 进化动机激活后就能引导人们加工有利于这种动机(或目标)实现的信息(如性别相关的风险信息等)。未来的进化动机影响社会认知的研究可以结合积极心理学(positive psychology)与具身认知(embodied cognition)的理论假设, 以产生更有价值的研究成果。 相似文献

This paper deals with optimal partitioning of limited testing time in order to achieve maximum total test score. Nonlinear
optimization theory was used to analyze this problem. A general case using a generic item response model is first presented.
A special case that applies a response time model proposed by Wang and Hanson (2005) is also presented. Theoretical properties
of the optimal solution are derived. Their practical implications to optimal test-taking strategies are also discussed. The
theoretical properties are in general agreement with the conventional advice to the examinees on pacing strategy. 相似文献

语音回路与阅读理解关系的眼动研究 总被引:4,自引:0,他引:4
语音回路是工作记忆中的一个重要成分。由于工作记忆在言语理解中有重要作用,所以负责加工语音信息的语音回路可能也和阅读理解有密切关系。但是,迄今为止直接研究语音回路影响阅读理解的研究不是很多,而且得出的结论也不太一致。研究使用眼动分析方法探讨语音回路与汉语阅读理解的关系。研究采用抑制发音和错误干扰相结合的范式考查正常条件下和抑制发音条件下的阅读特点的差别性。结果表明:(1)在一般阅读难度情况下,语音回路会延缓阅读速度;(2)两种阅读条件下都出现了同音效应,即同音字的首次注视时间、总注视时间都比非同音字短;(3)语音在汉语阅读的早期就发挥了作用,而且同音字错误比非同音字错误更容易被恢复 相似文献

Quantum dynamics of human decision-making 总被引:2,自引:0,他引:2
Jerome R. Busemeyer Zheng Wang James T. Townsend 《Journal of mathematical psychology》2006,50(3):220-241
A quantum dynamic model of decision-making is presented, and it is compared with a previously established Markov model. Both the quantum and the Markov models are formulated as random walk decision processes, but the probabilistic principles differ between the two approaches. Quantum dynamics describe the evolution of complex valued probability amplitudes over time, whereas Markov models describe the evolution of real valued probabilities over time. Quantum dynamics generate interference effects, which are not possible with Markov models. An interference effect occurs when the probability of the union of two possible paths is smaller than each individual path alone. The choice probabilities and distribution of choice response time for the quantum model are derived, and the predictions are contrasted with the Markov model. 相似文献

Culture and the Development of Self-Knowledge 总被引:3,自引:0,他引:3
Qi Wang 《Current directions in psychological science》2006,15(4):182-187
ABSTRACT— Although a great deal of work in the past decades has shown cultural variations in self-knowledge among adults, not until recently have researchers started to examine developmental processes and mechanisms that give rise to the variations. I discuss our research on the development of two kinds of self-knowledge: autobiographical memory and self-concept. Our findings indicate that children develop culture-specific self-knowledge early in life; the two kinds of self-knowledge reinforce each other at both individual and cultural levels; and early narrative practices constitute an important resource from which children draw cultural views about the self to incorporate into their self-understanding and remembering. 相似文献
