摘要
针对视听交互同时感知外界信息时视觉掩蔽效应的变化情况,设计4组实验进行分析讨论。视听注意属性是影响掩蔽效应的两个因素,实验采用这两个因素析因设计。实验发现,视觉掩蔽结果在视听双通道和单通道中有明显的差别。视觉注意属性对视觉掩蔽造成显著的变化,使视觉掩蔽发生区域趋于扩展或缩小,不同的视听注意属性使视觉掩蔽判断的反应时间明显延长。
In this paper, four group visual masking experiments are designed under different visual-auditory attention property. Attention property of visual and auditory is set as two factors which would influence visual masking. Factorial analysis experiment is designed. The result points out that the visual masking has obvious influence in visual-auditory attention compared with in visual only mode. Visual attention property changes visual masking clearly by extending or reducing visual masking region. Besides, visual reaction time is changed by attention property.
