尽管听觉刺激不直接传递与视觉刺激相关的信息，但听觉刺激往往能提高视觉检测和识别性能。听觉刺激经常根据感官输入的可靠性改变视觉感知，视觉和听觉信息相互补偿其他感官领域的模糊性。知觉加工具有半球不对称的特点。虽然左半球更多地参与语言处理，但右半球主导空间处理。在此背景下，我们假设在目标识别任务中，听觉促进效应存在于右视野，而在目标定位任务中，听觉促进效应也存在于左视野。在本研究中，我们使用双流快速串行视觉呈现来进行目标识别和定位任务。当将两个目标嵌入到快速串行视觉呈现流中时，第二目标的目标检测或识别性能通常低于第一目标；这种缺陷就是众所周知的“注意力闪烁”。结果表明，当视觉刺激出现在右侧视野时，听觉刺激提高了流内第二目标的识别能力，而在左侧视野中则没有。当视觉刺激出现在左视野时，听觉刺激能提高第二目标定位的表现。在知觉加工中观察到听觉促进效应，这取决于半球专业化。我们的研究结果表明，在刺激被投射的侧视觉半球和可能受益于听觉提示的视觉判断之间存在分离。
Even though auditory stimuli do not directly convey information related to visual stimuli, they often improve visual detection and identification performance. Auditory stimuli often alter visual perception depending on the reliability of the sensory input, with visual and auditory information reciprocally compensating for ambiguity in the other sensory domain. Perceptual processing is characterized by hemispheric asymmetry. While the left hemisphere is more involved in linguistic processing, the right hemisphere dominates spatial processing. In this context, we hypothesized that an auditory facilitation effect in the right visual field for the target identification task, and a similar effect would be observed in the left visual field for the target localization task. In the present study, we conducted target identification and localization tasks using a dual-stream rapid serial visual presentation. When two targets are embedded in a rapid serial visual presentation stream, the target detection or discrimination performance for the second target is generally lower than for the first target; this deficit is well known as attentional blink. Our results indicate that auditory stimuli improved target identification performance for the second target within the stream when visual stimuli were presented in the right, but not the left visual field. In contrast, auditory stimuli improved second target localization performance when visual stimuli were presented in the left visual field. An auditory facilitation effect was observed in perceptual processing, depending on the hemispheric specialization. Our results demonstrate a dissociation between the lateral visual hemifield in which a stimulus is projected and the kind of visual judgment that may benefit from the presentation of an auditory cue.
