Differences in audiovisual integration are commonly observed in autism. Temporal binding windows (TBWs) of audiovisual speech can be trained (i.e., narrowed) in non-autistic adults; this study evaluated a computer-based perceptual training in autistic youth and assessed whether treatment outcomes varied according to individual characteristics. Thirty autistic youth aged 8-21 were randomly assigned to a brief perceptual training (n = 15) or a control condition (n = 15). At post-test, the perceptual training group did not differ, on average, on TBWs for trained and untrained stimuli and perception of the McGurk illusion compared to the control group. The training benefited youth with higher language and nonverbal IQ scores; the training caused widened TBWs in youth with co-occurring cognitive and language impairments.
自闭症患者的视听整合通常存在差异。非自闭症成年人的视听言语的时窗（TBW）可以通过训练（即变窄）；本研究评估了针对自闭症青年的基于计算机的感知训练，并评估了治疗效果是否因个体特征而异。30 名 8-21 岁的自闭症青年被随机分配到短暂的感知训练组（n = 15）或对照组（n = 15）。在测试后，与对照组相比，感知训练组在训练和未训练刺激的 TBW 以及对 McGurk 错觉的感知方面平均没有差异。该训练对语言和非语言智商得分较高的青年有益；该训练导致同时存在认知和语言障碍的青年的 TBW 变宽。
