高中二年级学生中文阅读知觉广度的眼动研究

采用“呈现随眼动变化技术”对高中二年级学生中文阅读的知觉广度进行了眼动研究。结果发现,高中二年级学生的阅读知觉广度具有不对称性,大约为注视点左侧一个或两个汉字到注视点右侧三个或四个汉字的空间;高中二年级学生在正常阅读中的眼跳距离约为三个汉字的空间,在连续注视的过程中知觉广度有较小范围的重叠。     

算术应用题表征策略的眼动研究

采用EyelinkⅡ眼动记录仪,以21名大学生为被试,探讨了大学生解决三步比较应用题的表征策略。实验设计为2(正确率:高、低)×2(题型:一致、不一致)×2(无关信息:插入、未插入)的三因素混合实验。结果表明:(1)大学生被试解三步式比较应用题存在直译策略和问题模型策略;(2)解题正确率高者解难度较大的应用题时倾向于对应用题情境进行加工,即采用问题模型策略,正确率低者未表现出这一倾向,往往采用直译策略。     

中文阅读过程中字形快速启动的眼动研究

以字形相似的汉字为启动字,探讨字形信息激活在汉字识别中的时间进程。实验1采用命名任务考察三种启动时间条件下是否存在字形启动效应,结果发现当启动时间为35ms时,出现稳定的字形启动效应。实验2采用眼动记录法考察阅读过程中的快速启动,结果在三种启动时间条件下均未发现显著的启动效应。     

中文词汇切分对眼动数据的影响

该研究使用眼动研究中的“边界”技术范式,材料中的关键词为前两个字为双字词的三字词,如“服务员”,和非三字词,如“服务体”,考察可能存在的中文词汇切分策略对眼动时间指标的影响。实验使用2×2被试内设计,第一个因素是三字词的词频：高频和低频,第二个因素为不同词频条件下的非三字词基线。实验结果是三字词预视条件下的注视时间短于非三字词预视条件下的注视时间。结果表明自然阅读中的词汇切分策略确实存在,并且可以在眼动的时间指标上表现出来,结果还暗示在词汇切分过程中,读者在心理词典中对三字词的搜索是必需的过程。     

What the eyes already ‘know’: using eye movement measurement to tap into children's implicit numerical magnitude representations

To date, a number of studies have demonstrated the existence of mismatches between children's implicit and explicit knowledge at certain points in development that become manifest by their gestures and gaze orientation in different problem solving contexts. Stimulated by this research, we used eye movement measurement to investigate the development of basic knowledge about numerical magnitude in primary school children. Sixty‐six children from grades one to three (i.e. 6–9 years) were presented with two parallel versions of a number line estimation task of which one was restricted to behavioural measures, whereas the other included the recording of eye movement data. The results of the eye movement experiment indicate a quantitative increase as well as a qualitative change in children's implicit knowledge about numerical magnitudes in this age group that precedes the overt, that is, behavioural, demonstration of explicit numerical knowledge. The finding that children's eye movements reveal substantially more about the presence of implicit precursors of later explicit knowledge in the numerical domain than classical approaches suggests further exploration of eye movement measurement as a potential early assessment tool of individual achievement levels in numerical processing.

听觉诱发表象的眼动机制

视觉心理表象是一种基于过去经验的自上而下的加工过程,它是信息表征的一种形式.以往的研究主要采用视觉来诱发表象,但是这很难排除视觉后像的干扰,而且与表象“自上而下”的加工过程不一致.听觉诱发表象很好地解决了视觉后像的干扰问题,也更吻合表象“自上而下”的加工过程,因为被试产生的表象是基于自己过去的经验,从自身出发,主动加工的结果.采用实验法,考察通过听觉通道诱发表象眼动的情况,使用眼动仪记录被试的眼动轨迹.结果发现：（1）不管是运动还是静止的物体,都能诱发表象,在表象时存在眼动行为.（2）运动的物体诱发眼动的程度更大.（3）眼动影响表象的建构,在表象建构中起机能性作用.     

大学生恋爱决策中的内隐与外显线索偏好的研究

本研究旨在探索大学生恋爱决策中的内隐和外显线索的偏好差异。研究一在访谈和问卷调查的基础上,筛选出大学生在恋爱决策中关注的十四条线索,并让38名男性和52名女性大学生对这些线索进行重要性评分,从而比较不同性别的被试在线索重要性上的差异,结果显示不同性别的大学生在品行、个人修养、性格、职业、经济条件、家庭背景和学历这些线索上有显著差异;研究二分别选取了男性和女性大学生最为关注的前八条线索,并通过眼动仪探索被试进行恋爱决策时的内隐线索排序,与通过自陈问卷获得的外显线索排序进行比较,旨在探索被试的内隐与外显线索的重要性排序差异。研究二采用恋爱6个月以上关系稳定的眼动被试群体。结果显示,对于不同性别的被试,其内隐与外显条件下在某些线索重要性方面的排序上存在显著差异;女性被试的平均注视时间排序和对线索重要性排序在某些线索上也存在显著差异,而不同性别的被试对某些线索上的平均瞳孔大小排序上也和内隐线索重要性的排序上存在显著差异。     

The Confusion of Fear and Surprise: A Developmental Study of the Perceptual-Attentional Limitation Hypothesis Using Eye Movements

The goal of the present study was to test the Perceptual-Attentional Limitation Hypothesis in children and adults by manipulating the distinctiveness between expressions and recording eye movements. Children 3–5 and 9–11 years old as well as adults were presented pairs of expressions and required to identify a target emotion. Children 3–5 years old were less accurate than those 9–11 years old and adults. All children viewed pictures longer than adults but did not spend more time attending to the relevant cues. For all participants, accuracy for the recognition of fear was lower than for surprise when the distinctive cue was in the brow only. They also took longer and spent more time in both the mouth and brow zones than when a cue was in the mouth or both areas. Adults and children 9–11 years old made more comparisons between the expressions when fear comprised a single distinctive cue in the brow than when the distinctive cue was in the mouth only or when both cues were present. Children 3–5 years old made more comparisons for brow only than both. The results of the present study extend on the Perceptual-Attentional Limitation Hypothesis showing an importance of both decoder and stimuli, and an interaction between decoder and stimuli characteristics.     

词素位置概率在中文阅读中的作用：词汇判断和眼动研究

中文词切分的认知机制一直是心理语言学关注的焦点问题之一,研究发现中文读者可使用词素位置概率等语言学线索帮助词切分,而首、尾词素位置概率的重要程度以往研究观点并不一致。本研究通过词汇判断和眼动实验,考察中文读者对首、尾词素位置概率的利用情况。实验1a和1b采用词汇判断任务,考察在不同词频条件下词首与词尾词素位置概率对词汇识别的影响。在错误率和反应时指标上,高频词条件下词首与词尾词素位置概率效应不显著;低频词条件下词首词素位置概率效应显著,词尾词素位置概率效应不显著。实验2a和2b采用句子阅读任务,考察在自然阅读情境中被试对词素位置概率的运用。在凝视时间、回视路径时间和总注视时间指标上,低频词条件下词首词素位置概率效应显著,词尾词素位置概率效应不显著。高频词条件下词首与词尾词素位置概率效应均不显著。词汇判断和眼动证据共同表明,词素位置概率信息是中文读者重要的语言词切分线索,且与词尾词素位置概率相比,词首词素位置概率在词汇切分与识别过程中发挥的作用更大。同时,词素位置概率线索的运用会受到词频的影响,研究结果支持复合词加工的混合通达表征模型。
