摘　　要：采用比较视觉搜索任务和眼动追踪技术,通过增加组成图片的图形数量和改变不同图形的特征属性,考察比较视觉搜索任务是否遵循工作记忆最小化原则以及图形特征加工的优先性问题。结果表明图形数量的增加不影响平均每次注视的图形数量,被试平均每次注视1.65个图形,即比较视觉搜索任务仍遵循工作记忆最小化原则。不同图形中颜色和形状都不同的注视时间最短,颜色不同和形状不同在注视时间上差异不显著,表明比较视觉搜索任务中特征维度数量比特征性质在引导注意上具有优先性。事先不规定搜索路径的情况下,被试主要采用系统搜索策略完成比较搜索任务。We manipulated the display size and object identities to investigate whether the comparative search task follows minimal use of working memory and priority for processing features using eye tracking. The number of fixations per scene glance suggested that on average, 1.65 objects per fixation were encoded and maintained in visual working memory despite increased display size. color-only and shape-only trials, and no difference demonstrated that the number of features is of greater Fixation times were shorter for redundant trials than for between color-only and shape-only trials. These results attentional priority than feature characteristics. Participants mostly used systematic search strategy to complete the tasks when they were provided no instruction the visual-spatial processing strategy they were to employ. regarding
