| 摘 要： | 在视听交互环境中,当视觉和听觉掩蔽刺激同时感知时,对视听觉的相互作用及掩蔽变化问题进行了实验研究。将视听交互场景按注意状态分类,实验测量了不同场景中视觉和听觉掩蔽阈值的变化,讨论了不同视觉和听觉掩蔽刺激的相互影响。实验结果发现对比单任务实验的阈值,不同视听交互环境中视觉和听觉的掩蔽阈值会产生相应变化。由实验结果可以推论视听交互环境中注意分配影响视觉和听觉掩蔽效应,并且视听掩蔽刺激的相互作用会进一步影响视觉和听觉唤起的注意。

| Abstract: | The visual and auditory masking variations are discussed when visual and auditory stimulus are perceived simultaneously.The visual-auditory interaction conditions are labeled using the attention conditions.Then the change of masking threshold is to be tested and measured.The interaction between visual and auditory masking is discussed. It is found that the masking thresholds would be changed in the visual-auditory interaction condition compared to the visual or auditory tasks only.Based on the study,it could be concluded that the visual and auditory masking effect would be influenced by attention variation in visual-auditory interaction.The aroused attention would be interfered by interaction between visual and auditory masking stimulus. |
