非预想刺激的颜色和形状特征对无意视盲的影响

摘要

When engaged in a visual task, people often negelect unexpected stimulus that appearing in the visual field. This phenomenon is called inattentional blindness. In this study, we examine the influence of the unexpected stimulus＂ color and shape on inattent%当人们专注于某件事时往往会忽略出现在眼前的其他事物，这一现象被称为“无意视盲”（inattentional blindness）。通过采用持续的动态实验范式并调控任务相关维度和任务无关维度，考察了非预想刺激的颜色和形状特征对无意视盲的影响，实验结果显示：（1）当任务相关维度是颜色、任务无关维度为形状时，颜色一致条件比不一致条件更容易觉察到非预想刺激“十”；（2）当任务相关维度是形状、任务无关维度是颜色时．形状一致性、颜色一致性对无意视盲无显著影响。结果表明，非预想刺激的颜色和形状特征对无意视盲产生影响，且
