Abstract

Synaesthesia is a multimodal phenomenon in which the activation of one sensory modality leads to an involuntary additional experience in another sensory modality. To date, normal multisensory processing has hardly been investigated in synaesthetes. In the present study we examine processes of audiovisual separation in synaesthesia by using a simultaneity judgement task. Subjects were asked to indicate whether an acoustic and a visual stimulus occurred simultaneously or not. Stimulus onset asynchronies (SOA) as well as the temporal order of the stimuli were systematically varied. Our results demonstrate that synaesthetes are better in separating auditory and visual events than control subjects, but only when vision leads.

联觉中的视听同时性判断

联觉是一种多模态现象，其中一种感觉模态的激活会导致另一种感觉模态出现不自主的额外体验。迄今为止，人们还很少研究联觉患者的正常多感官处理过程。在本研究中，我们通过同时性判断任务来研究联觉中的视听分离过程。受试者被要求指出声刺激和视刺激是否同时出现。刺激的起始不同步（SOA）以及刺激的时间顺序被系统地改变。我们的研究结果表明，联觉过敏者比对照组受试者更善于区分听觉和视觉事件，但仅限于视觉先行的情况。

期刊介绍： Multisensory Research is an interdisciplinary archival journal covering all aspects of multisensory processing including the control of action, cognition and attention. Research using any approach to increase our understanding of multisensory perceptual, behavioural, neural and computational mechanisms is encouraged. Empirical, neurophysiological, psychophysical, brain imaging, clinical, developmental, mathematical and computational analyses are welcome. Research will also be considered covering multisensory applications such as sensory substitution, crossmodal methods for delivering sensory information or multisensory approaches to robotics and engineering. Short communications and technical notes that draw attention to new developments will be included, as will reviews and commentaries on current issues. Special issues dealing with specific topics will be announced from time to time. Multisensory Research is a continuation of Seeing and Perceiving, and of Spatial Vision.
