Abstract

Atypical sensory processing is now considered a diagnostic feature of autism. Although multisensory integration (MSI) may have cascading effects on the development of higher-level skills such as socio-communicative functioning, there is a clear lack of understanding of how autistic individuals integrate multiple sensory inputs. Multisensory dynamic information is a more ecological construct than static stimuli, reflecting naturalistic sensory experiences given that our environment involves moving stimulation of more than one sensory modality at a time. In particular, depth movement informs about crucial social (approaching to interact) and non-social (avoiding threats/collisions) information. As autistic characteristics are distributed on a spectrum over clinical and general populations, our work aimed to explore the multisensory integration of depth cues in the autistic personality spectrum, using a go/no-go detection task. The autistic profile of 38 participants from the general population was assessed using questionnaires extensively used in the literature. Participants performed a detection task of auditory and/or visual depth moving stimuli compared to static stimuli. We found that subjects with high-autistic traits overreacted to depth movement and exhibited faster reaction times to audiovisual cues, particularly when the audiovisual stimuli were looming and/or were presented at a fast speed. These results provide evidence of sensory particularities in people with high-autistic traits and suggest that low-level stages of multisensory integration could operate differently all along the autistic personality spectrum.

是什么使自闭症特征谱中对运动的检测不同?视听深度范式的证据。
非典型的感觉处理现在被认为是自闭症的一个诊断特征。尽管多感官整合(MSI)可能对社会交际功能等更高层次技能的发展产生级联效应,但对自闭症患者如何整合多种感官输入显然缺乏了解。多感官动态信息是一种比静态刺激更具生态性的结构,反映了自然的感官体验,因为我们的环境一次涉及多个感官模式的移动刺激。特别是,深度移动会告知关键的社交(接近互动)和非社交(避免威胁/碰撞)信息。由于自闭症特征在临床和普通人群中分布在一个谱上,我们的工作旨在探索自闭症人格谱中深度线索的多感官整合,使用去/不去检测任务。使用文献中广泛使用的问卷对来自普通人群的38名参与者的自闭症状况进行了评估。与静态刺激相比,参与者执行了听觉和/或视觉深度移动刺激的检测任务。我们发现,具有高度自闭症特征的受试者对深度运动反应过度,对视听线索的反应时间更快,尤其是当视听刺激迫在眉睫和/或以快速呈现时。这些结果为具有高度自闭症特征的人的感官特殊性提供了证据,并表明在自闭症人格谱中,多感官整合的低水平阶段可能会有不同的运作方式。

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.
