视觉干扰干扰触觉时序判断（TOJ）在适度短的刺激起始时间（SOA）在典型的发展中国家的参与者。将橡胶手以向前的方向呈现给参与者的手增强了这种效果，而以相反的方向呈现则减弱了这种效果。自闭症谱系障碍（ASD）的个体具有非典型的多感觉处理，然而，在ASD的非典型多感觉处理的干扰的影响仍然不清楚。在这项研究中，我们研究了视觉干扰对ASD患者触觉TOJ的影响。在一个不透明的盒子里，两个连续的触觉刺激被传递到参与者右手的食指和无名指。将橡胶手以向前或反向的方向放置在盒子上。同时，由橡胶手手指上的发光二极管提供的视觉刺激以一致或不一致的顺序传递。参与者被要求判断触觉刺激的时间顺序，而不管视觉干扰。在没有视觉刺激的情况下，与典型的开发（TD）控制相比，ASD的参与者倾向于判断同时刺激作为无名指在触觉TOJ期间首先受到刺激，一致的视觉刺激消除了偏见。当提供不一致的视觉刺激时，ASD参与者的判断明显逆转，无论橡胶手的方向如何。研究结果表明，有相当大的影响，视觉干扰的触觉TOJ在个人与ASD。
Visual distractors interfere with tactile temporal order judgment (TOJ) at moderately short stimulus onset asynchronies (SOAs) in typically developing participants. Presentation of a rubber hand in a forward direction to the participant’s hand enhances this effect, while that in an inverted direction weakens the effect. Individuals with autism spectrum disorder (ASD) have atypical multisensory processing; however, effects of interferences on atypical multisensory processing in ASD remain unclear. In this study, we examined the effects of visual interference on tactile TOJ in individuals with ASD. Two successive tactile stimuli were delivered to the index and ring fingers of a participant’s right hand in an opaque box. A rubber hand was placed on the box in a forward or inverted direction. Concurrently, visual stimuli provided by light-emitting diodes on the fingers of the rubber hand were delivered in a congruent or incongruent order. Participants were required to judge the temporal order of the tactile stimuli regardless of visual distractors. In the absence of a visual stimulus, participants with ASD tended to judge the simultaneous stimuli as the ring finger being stimulated first during tactile TOJ compared with typically developing (TD) controls, and congruent visual stimuli eliminated the bias. When incongruent visual stimuli were delivered, judgment was notably reversed in participants with ASD, regardless of the direction of the rubber hand. The findings demonstrate that there are considerable effects of visual interferences on tactile TOJ in individuals with ASD.
