The temporal occurrence of a flash can be shifted towards a slightly offset sound (temporal ventriloquism). Here we examined whether four-dot masking is affected by this phenomenon. In Experiment 1, we demonstrate that there is release from four-dot masking if two sounds--one before the target and one after the mask--are presented at approximately 100 ms intervals rather than at approximately 0 ms intervals or a silent condition. In Experiment 2, we show that the release from masking originates from an alerting effect of the first sound, and a temporal ventriloquist effect from the first and second sounds that lengthened the perceived interval between target and mask, thereby leaving more time for the target to consolidate. Results thus show that sounds penetrate the visual system at more than one level.
闪光出现的时间可以向稍有偏移的声音方向偏移（时间性腹语术）。在此，我们研究了四点掩蔽是否受此现象影响。在实验1中，我们证明，如果以大约100毫秒的间隔而不是大约0毫秒的间隔或无声条件呈现两个声音——一个在目标之前，一个在掩蔽之后——四点掩蔽就会解除。在实验2中，我们表明，掩蔽的解除源于第一个声音的警觉效应，以及第一个和第二个声音产生的时间性腹语效应，这种效应延长了目标与掩蔽之间的感知间隔，从而为目标巩固留出了更多时间。结果因此表明，声音在不止一个层面穿透视觉系统。
