【摘要】：伪忽视(pseudoneglect)是指健康个体在空间注意上所存在的轻微左偏现象。常用线段平分任务和灰度标尺任务来研究[18],其中阅读方向对伪忽视的影响存在的争论最多。研究者一致认为从左往右的阅读者存在左偏现象,而从右往左的阅读者出现三种结果:(1)出现右偏;(2)出现左偏现象;(3)没有偏向。本研究在此基础上进行完善并进一步研究伪忽视现象。本研究使用加拿大SR公司生产的Eyelink-2000型眼动仪,以母语为维吾尔语的维-汉双语大学生为被试,采用线条平分任务和场景图片任务,分别设计了四个实验来研究。实验一:研究维-汉双语者优势浏览方向与语言经历和水平之间的关系。结果表明优势浏览方向从右往左的百分率与中文经历和英语经历有显著得负高相关。且从右往左优势浏览方向的百分率与中文水平呈负的中等相关、与英文水平呈负的低相关。从右往左优势浏览方向的百分率与维吾尔语水平、维吾尔语经历呈负低相关。实验二:研究维-汉双语者优势浏览方向在线条平分任务上对伪忽视的影响以及线条平分任务中线条的长度、位置对伪忽视的影响。结果表明优势浏览方向从左往右的被试在线条平分任务上偏向左侧,优势浏览方向从右往左的被试在线条平分任务上向右偏。优势浏览方向从右往左的被试出现了线条的位置效应。而从左往右优势浏览方向的被试在当线条在屏幕的左侧时左偏程度最小。线条在屏幕的中心和右侧时偏差程度没有显著的变化。两种优势浏览方向的被试均不存在线条的长度效应。实验三:研究维-汉双语者的优势浏览方向对伪忽视在场景知觉上的影响,结果表明不同优势浏览方向的被试首次扫描均从图片的右侧开始扫描。随后的扫描会出现随窗口的变化而变化。在总的扫描次数上,不同优势浏览方向的被试对图片左侧有不同频率的扫描,但均对图片右侧的扫描多于图片左侧。实验四:伪忽视是否可以移动窗口的设置来改变,通过再次对线条平分来检验改变的效果;伪忽视可以通过移动窗口的不对称设计进行改变,但改变的效果没有达到显著差异。在本实验设计下得出以下结论:(1)不同阅读方向的语言文字接触频率和语言水平均会影响优势浏览方向的形成。(2)优势浏览方向会影响伪忽视现象,即优势浏览方向从左往右的被试会出现左偏,而从右往左的被试会出现右偏。线条位置会影响伪忽视,主要表现在优势浏览方向从右往左的被试中,但线条长度不影响伪忽视。(3)不同优势浏览方向的被试均从图片的右侧开始扫描。在总的扫描次数上,不同优势浏览方向的被试对图片左侧有不同频率的扫描,但均对图片右侧的扫描多于图片左侧。(4)设置不对称窗口可以改变伪忽视,左右设置窗口分别对被试的左右偏有显著的加强,但左设置窗口对被试的右偏及右设置窗口对被试左偏的改变没有达到显著效果。
[Abstract]:Pseudoneglect is a slight left-leaning phenomenon in spatial attention of healthy individuals. Line segment task and gray scale task are commonly used to study [18], in which the effect of reading direction on pseudo-neglect is the most controversial. The researchers agree that the readers from left to right have left deviations, while readers from right to left have three results: 1) and 2) the phenomenon of left deviation. This study is based on the improvement and further study of the phenomenon of pseudo-neglect. In this study, four experiments were designed using Eyelink-2000 eye movement instrument produced by SR Company of Canada, Uygur native language Uygur bilingual Uygur students as subjects, line division task and scene picture task. Experiment 1: to study the relationship between the dominant browsing direction and language experience and level of Uighur-Chinese bilinguals. The results showed that the percentage of dominant browsing direction from right to left was significantly negatively correlated with Chinese and English experience. The percentage of dominant browse direction from right to left is negatively correlated with Chinese level and low with English level. The percentage of dominant browsing direction from right to left was negatively correlated with Uygur language level. Experiment 2: the influence of dominant browsing direction of Uighur-Chinese bilinguals on pseudo-neglect in line partition task and the influence of line length and position on pseudo-neglect were studied. The results showed that the dominant browsing direction from left to right tilted to the left on the line equal task, and the dominant browsing direction from right to left shifted to the right on the line equal task. The dominant browse direction from right to left subjects appeared line position effect. The subjects with dominant left-to-right browsing direction had the least left deviation when the lines were on the left side of the screen. There is no significant change in the deviation between the center and right side of the screen. There was no line length effect in the two dominant browsing directions. Experiment 3: the effect of the dominant browsing direction of Uighur-Chinese bilinguals on the perception of pseudo-neglect was studied. The results showed that the subjects with different dominant browsing directions were scanned from the right side of the picture for the first time. Subsequent scans will vary with the window. In the total scanning times, the subjects with different dominant browsing directions scanned the left side of the picture at different frequencies, but they scanned more on the right side of the picture than on the left side of the picture. Experiment 4: whether pseudo-neglect can change the setting of moving window, and test the effect of change by dividing the lines equally again; pseudo-neglect can be changed by the asymmetric design of moving window, but the effect of change has not reached significant difference. In this experimental design, the following conclusions are drawn: 1) the frequency of language contact and language proficiency in different reading directions will affect the formation of dominant browsing direction. That is, the dominant browsing direction from left to right will appear left deviation, and from right to left participants will appear right deviation. Line position affects pseudo-neglect, mainly in the subjects whose dominant browsing direction is from right to left, but line length does not affect pseudo-neglect. 3) all the subjects with different dominant browsing directions scan from the right side of the picture. In the total scanning times, the subjects with different dominant browsing directions had different frequency of scanning on the left side of the picture, but they all had more scanning on the right side of the picture than on the left side of the picture. 4) setting an asymmetrical window could change the pseudo-neglect. The left and right setting windows significantly strengthened the left and right deviations of the subjects, but the changes of the left and right setting windows to the left deviations of the subjects were not significant.
