名词具体性效应的眼动研究

通两个实验考察名词的具体性效应.实验一采用词汇判断法,考察名词的具体性效应.采用2（具体性：具体、抽象）×2（词频：高频、低频）的两因素被试内实验设计.结果表明：低频词存在具体性效应.实验二应用眼动技术,以EyelinkⅡ眼动仪为工具,考察在句子阅读中的名词具体性效应.实验为单因素被试内设计,自变量为句子中目标词的具体性.结果表明：在句子语境条件下,低频词也存在具体性效应,而且这种效应表现在低频词的晚期加工阶段.     

Disrupted attentional learning in high schizotypy: Evidence of aberrant salience

The relationship between learned variations in attention and schizotypy was examined in two experiments. In Experiment 1, participants low on a negative subscale of schizotypy exhibited an explicit bias in overt attention towards stimuli that were established as predictive of a trial outcome, relative to stimuli that were irrelevant. The same participants also showed a bias in learning about these stimuli when they presented in a novel context. Neither of these effects was observed in participants high in schizotypy. In Experiment 2, participants low on the negative subscale of schizotypy exhibited faster reaction times towards a target that was cued by a stimulus that had a history of predictive validity relative to a stimulus that had a history of irrelevance. Again, this effect was not present in participants high in schizotypy. These results imply a disruption in the normal allocation of attention to cues that have predictive significance in schizotypy.     

视听时、空一致性对Pip-and-Pop效应的影响

多感觉整合遵循空间原则和时间原则, 有研究表明Pip-and-Pop效应产生的原因是多感觉整合, 那么Pip-and-Pop效应是否同样遵循空间原则和时间原则呢?本研究采用动态视觉搜索范式, 通过两个眼动实验考察空间一致性(实验1)和时间一致性(实验2)对Pip-and-Pop效应的影响。结果发现：(1)当视觉目标颜色变化伴随一个同侧的听觉刺激时所产生的Pip-and-Pop效应最大, 对侧条件没有发现Pip-and-Pop效应。(2)视听刺激同时呈现所产生的Pip-and-Pop效应最大, 随视听刺激呈现时间间隔的增加Pip-and-Pop效应逐渐减弱直至消失。结果表明, 视听时、空一致性对Pip-and-Pop效应具有调节作用, 这为多感觉整合在产生Pip-and-Pop效应中的作用提供了证据。     

观看撕去标签的产品的心理反应:完形还是蔡格尼克?

产品包装标签是人们获取产品信息的最主要途径之一,而影视片段中常出现“去标签”处理的道具。本文以熟悉品牌的矿泉水为例,采用眼动分析法和问卷测量法结合的方式对有无产品标签的影响进行探究。结果表明:受众在观看影视片段中“去标签”处理的道具时的心理反应与完形理论中的知觉组织原则——闭合原则有关,为广告设计提供了新的观点和实证依据。     

视频教学中教师的眼神注视能否促进学习?

教师的眼神注视是在视频学习中重要但易被忽视的元素。以往理论存在两种对立的观点：其中准社会交往理论和社会代理理论支持教师的眼神注视促进学习; 而基于多媒体学习认知理论与认知负荷理论认为教师的眼神注视会阻碍学习效果。通过汇总以往实证研究得出如下结论：首先, 教师的眼神注视对学习效果具有小的促进效应, 即教师的眼神注视能够促进学习者的保持成绩(d_保持 = 0.41)和迁移成绩(d_迁移 = 0.39); 其次, 在主观体验上, 教师的眼神注视对准社会交往也具有小的促进效应(d_{准社会交往} = 0.35), 而教师的眼神注视对认知负荷影响十分微弱(d_认知负荷 = -0.02); 最后, 在对学习材料的注意加工上, 教师的眼神注视总体上影响比较微弱(d_注视时间 = 0.06, d_{首次注视时间} = -0.15)。未来研究需要对不同注视类型、先前知识经验、学习材料性质以及认知神经方法进一步探究。     

词频与阅读方式对词跨行呈现效应的影响

通过使用眼动追踪技术,采用2（呈现条件：同行呈现、跨行呈现）×2（词频：高频、低频）×2（阅读方式：朗读、默读）的被试内实验设计,探讨了词频和阅读方式对词跨行呈现效应的影响。结果发现,呈现条件、词频和阅读方式的主效应显著,跨行呈现、低频和朗读的凝视时间和总注视时间更长、总注视次数更多;呈现条件之间在凝视时间上的差异,高频词大于低频词;呈现条件之间在凝视时间和总注视次数上的差异,朗读大于默读。结果表明,词跨行呈现干扰了阅读,且这种干扰作用受词频和阅读方式的影响。     

Eye movement suppression interferes with construction of object-centered spatial reference frames in working memory

The brain’s frontal eye fields (FEF), responsible for eye movement control, are known to be involved in spatial working memory (WM).In a previous fMRI experiment (Wallentin, Roepstorff & Burgess, Neuropsychologia, 2008) it was found that FEF activation was primarily related to the formation of an object-centered, rather than egocentric, spatial reference frame. In this behavioral experiment we wanted to demonstrate a causal relationship between eye movement control and manipulation of spatial reference frames. Sixty-two participants recalled either spatial (“Was X in front of Y?”) or non-spatial (“Was X darker than Y?”) relations in a previously shown image containing two to four objects, each with an intrinsic orientation and unique luminance. During half of all recall trials a moving visual stimulus was presented, which participants had to ignore, thus suppressing eye movement. Response times were significantly slower for spatial relations with distraction while there was no effect on non-spatial relations. There was no effect on accuracy, i.e. WM maintenance. This is consistent with the hypothesis that in spatial representations the FEFs are involved in WM content manipulation, such as establishing an object-centered spatial frame of reference.     

The eyes know what you are thinking: eye movements as an objective measure of mind wandering

Paralleling the recent work by Reichle, Reineberg, and Schooler (2010), we explore the use of eye movements as an objective measure of mind wandering while participants performed a reading task. Participants were placed in a self-classified probe-caught mind wandering paradigm while their eye movements were recorded. They were randomly probed every 2–3 min and were required to indicate whether their mind had been wandering. The results show that eye movements were generally less complex when participants reported mind wandering episodes, with both duration and frequency of within-word regressions, for example, becoming significantly reduced. This is consistent with the theoretical claim that the cognitive processes that normally influence eye movements to enhance semantic processing during reading exert less control during mind wandering episodes.

平滑追踪眼动及其对运动物体时空特征表征和预测的影响

平滑追踪眼动是人们对环境中感兴趣的运动物体进行持续视觉追踪的一种眼动行为, 它受个体在其过程中获得的视觉信息和眼动反馈信息等感知觉因素, 以及心理表征和期待等高水平认知因素的影响。同时, 平滑追踪眼动过程影响着个体的预测性眼动追踪、追赶性眼跳、空间定位和接触时间估计等涉及运动物体时空特征表征和预测的行为。未来的研究应注意探讨在平滑追踪眼动过程中获得的感知觉信息和高水平认知因素对上述时空特征表征和预测行为的影响。
