客体及其位置记忆的眼动研究(中文)

In this paper we briefly describe preliminary data from two experiments that we have carried out to investigate the relationship between visual encoding and memory for objects and their locations within scenes. In these experiments, we recorded participants′ eye movements as they viewed a photograph of a cubicle with 12 objects positioned pseudo-randomly on a desk and shelves. After viewing the photograph, participants were taken to the actual cubicle where they undertook two memory tests. Participants were asked to identify the 12 target objects(from the photograph)presented amongst 12 distractors. They were then required to place each of the objects in the location that they occupied in the photograph. These tests assessed participants′ memory for identity of the objects and their locations. In Experiment 1, we assessed the influence of the encoding period and the test delay on object identity and location memory. In Experiment 2 we manipulated scanning behaviour during encoding by "boxing"some of the objects in the photo. We showed that using boxes to change eye movement behaviour during encoding directly affected the nature of memory for the scene. The results of these studies indicate a fundamental relationship between visual encoding and memory for objects and their locations. We explain our findings in terms of the Visual Memory Model(Hollingworth & Henderson, 2002).     

泰文和中文阅读过程中的眼动控制(中文)

This paper analyses some aspects of the eye movement behaviour of readers of Thai and Chinese. The main focus is on readers′landing site distributions on words and how these are affected by the lack of clear word boundary information due to the absence of inter-word spaces. Empirical evidence from Thai and Chinese readers suggest that readers can relatively accurately target word centres. We make the case that this accuracy can be accounted for by a default targetting model(effectively, the prior landing site distribution, in Bayesian terms)modulated by statistical cues about word beginnings available from word-initial character frequencies.     

语言期望概率、不确定性输入及其对阅读的眼动研究启示(中文)

One nearly ubiquitous assumption in models of linguistic comprehension and of eye movement control in reading alike is of partial modularization between word-level and sentence-level processing: that the outcome of word recognition, and thus the input to sentence-level comprehension, is a categorial representation. Yet such a partial modularization throws away residual uncertainty regarding word identity that might potentially be of value to the comprehender further downstream in the sentence. Here I describe a line of research combining computational modeling with experimental eye-tracking work to explore the consequences of removing this partial modularity assumption.     

视觉选择过程中眼跳与注意关系的理论进展

视觉选择的过程包含两种途径:眼跳行动和注意转移,两者对于视觉选择目标物的加工都有促进作用。鉴于此,视觉研究领域产生大量关于二者关联如何的实验研究,大部分研究者认为眼跳和注意转移存在密切联系。该文将关于两者关系的重要理论进行了综合阐述和简要比较,主要介绍五种理论假说:眼动准备假说、动前假说、顺序注意模型、视觉注意模型和竞争整合模型。     

空格在文本阅读中的作用

本文总结空格在文本阅读中作用的相关研究, 主要包括以下内容: (1)删除或替代有空格文本中的空格, 对阅读产生的干扰作用; (2)在无空格的文本中插入空格, 对阅读产生一定的促进作用, 空格在汉语阅读中的作用受被试阅读经验、阅读方式和空格大小等因素影响; (3)被试母语和第二语言呈现方式的一致性会影响空格在第二语言阅读中的作用; (4)今后应结合眼动控制理论, 从注视点落点位置和熟悉性等方面开展研究。     

词汇获得年龄效应的眼动研究

采用两个实验考察了获得年龄因素在汉语词汇识别中的作用。实验一采用经典的词汇判断任务考察了获得年龄和词频因素在词汇判断中的作用,结果发现获得年龄和词频两个因素均影响词汇识别。实验二采用阅读句子任务,通过实时记录的眼动追踪技术进一步考察了在有语境的情况下,获得年龄和词频因素在词汇加工中的作用。结果发现,在阅读句子任务中,词汇获得年龄和词频因素都在词汇加工中起作用,二者存在交互作用,晚获得词存在词频效应。两个实验的结果均支持了在汉语词汇识别中,存在获得年龄效应。     

前分类声音存储器对声调和情绪韵律的加工

采用系列位置回忆任务, 探讨作为声调语言的汉语普通话中声调及情绪信息是否具有近因及后缀效应, 从而揭示同为超音段信息的声调和情绪韵律在前分类声音存储器(Precategorical Acoustic Storage, PAS)中是否具有单独的表征, 及该表征可能受到哪些因素的影响。实验一和二分别考察了声调是否具有近因和后缀效应, 实验三和四分别考察了情绪信息是否具有近因和后缀效应。实验结果发现两者均在PAS存储器中有单独的表征, 但这种表征会受到一些因素的影响, 且受影响的方式不一样。研究结果表明作为超音段信息的声调和情绪信息在表征上的不稳定性和脆弱性, 及在短时记忆加工过程中的特殊性。     

汉语句子理解中句法启动机制的眼动和ERP研究

语言产生的句法启动效应在近20年得到较深入研究。那么, 语言理解和语言产生中, 句法启动效应具有相同的加工机制吗？近些年, 研究者考察了印欧语系语言理解中的启动效应, 但还存在较多争论。这究竟是句法效应, 还是策略或者语义效应, 是词汇驱动还是词汇独立的？而且, 这是人类语言理解的语系特性还是普遍特性？单独采用行为技术、眼动技术或者ERP技术很难为这些争论提供坚实的实验证据和较深入的理论解释。鉴于此, 本项目拟采用眼动和ERP结合的技术, 从心理学、语言学和认知神经科学等多学科交叉的视角考查汉语句子理解的句法启动效应。通过分析眼动和ERP实验提供的一致性和差异性证据, 本项目力图阐明和揭示汉语句子理解中句法启动效应的认知特点和机制, 检验内隐学习理论和论元结构理论在解释句法启动效应时的适用性。     

初中二年级学生字词阅读知觉广度的眼动研究

采用眼动研究中经典的移动窗口技术范式探讨中学生字词阅读知觉广度。通过两个实验分别对17名初中二学生和12名初中二学生进行了汉语字、词阅读知觉广度的眼动研究。实验1结果表明,初中二年级学生字窗口条件下的阅读知觉广度为注视点左侧1个单字到右侧2个单字的范围;实验2结果表明,双字词窗口条件下的阅读知觉广度为注视点左侧1个双字词到右侧1个双字词的范围。本研究推论汉语阅读过程进行的是词单元加工,而不是单字。
