听标对视觉预警信息注意加工的影响

Influence of Auditory Icons on the Attentional Processing of Visual Warning Icons

目的:本研究旨在考察听标对视觉预警信息注意加工的影响。方法:包括两个实验,实验1以30名大学生为被试使用点探测范式,实验2以38名大学生为被试使用视觉搜索范式。结果:点探测任务的结果显示,在注意的早期加工阶段,同步呈现的听标会诱发被试对视觉预警标识的注意偏向,但这一现象并未出现在注意的晚期加工阶段。视觉搜索任务的结果显示,延后出现的听标会加快视觉预警标识的搜索速度。结论:在不同的任务中,不同呈现时间的听标对视觉预警标识的注意具有正向促进作用。

Objective:The present study explored the influence of auditory icons on the attentional processing of visual warning icons.Methods:Experiment 1 adopted the dot-probe paradigm.In Experiment 1,thirty college students were re⁃cruited.Experiment 2 adopted visual search paradigm.Thirty-eight college students participated in Experiment 2.Re⁃sults:The results of dot-probe task showed that,the simultaneously presented auditory icons induced the participants’at⁃tention bias towards the visual warning icons in the early stage of attentional processing,while no such phenomenon was found in the late stage of attentional processing.The results of visual search task revealed that the delayed presentation of the auditory icons reduced the reaction time in search of the visual warning icons.Conclusion:In different tasks,auditory icons presented at different times could positively promote the attention of visual warning icons.
