Abstract

Abstract: In current research, EyeLink Ⅱ eye tracker was used to explore the eccentricity effect in pro- and antisaccade tasks of university students, which means the systematical influences on saccade performance of the eccentricity of target stimulus in saccadic

Key words: saccade, prosaccade; antisaccade, eccentricity effect

摘要： 采用完全被试内设计，控制了眼跳任务类型（朝向眼跳、反向眼跳）和目标偏心距水平，考察了大学生在两种眼跳任务中的偏心距效应，即目标刺激相对于屏幕中心的距离对于眼跳过程的影响。研究结果发现：（1）反向眼跳任务中的首次眼跳方向错误率显著高于朝向眼跳，眼跳潜伏期也显著较长。（2）在朝向和反向眼跳过程中，都出现了目标的偏心距效应，即随着目标偏心距的增大，眼跳潜伏期缩短，眼跳落点视角增大。
