摘　　要：目的通过分析被试对横向平行线段的知觉,研究横向平行错觉的行为表现和眼动模式。方法本研究分为2个实验,实验一向25名被试呈现横向平行线段,要求选出较长的线段。实验二在实验一的基础上采用眼动技术,分析25名被试知觉横向平行线段时的注视次数和注视时间。结果 (1)被试在平行线段长度相等时,判断上方更长的反应率为62.8%,显著高于理论反应率50%;(2)被试对上方线段的注视次数和注视时间均显著大于下方线段。结论 (1)横向平行错觉是一种新的错觉,表现为等长的横向平行线段知觉为上方线段更长;(2)横向平行错觉的眼动模式表现为被试将的注视点集中到上方线段,因此认为上方线段更长。Objective Investigate the behavioral expression and the oculomotor mechanism of horizontally parallel lines illusion by analyzing the perception of horizontal parallel lines. Methods Experiment one required 25 subjects to choose the longer line between two horizontal parallel lines. Experiment two used eye tracking technique to explore the oculomotor mechanism of horizontally parallel lines illusion by analyzing numbers of fixation and fixation duration. Results （ 1 ） When lines were at the same length,the response rate （the percentage of trials on which subjects per- ceived the one above longer） was 62.8% that is higher than the random level （50%）. （2） Numbers of fixation points and fixation duration of the line above were significantly more/longer than the one below. Conclusion （ 1 ） This study discovered the illusion of horizontally parallel lines ： the one above of two horizontally parallel lines of the same length is perceived longer. （2） The oculomotor mechanism of horizontal parallel lines illusion was that subjects usually deploy more attention resources to the line above, thus perceiving it longer.
