This study examined the effect of increasing visual perceptual load on auditory awareness for social and non-social stimuli in adolescents with autism spectrum disorder (ASD, n = 63) and typically developing (TD, n = 62) adolescents. Using an inattentional deafness paradigm, a socially meaningful ('Hi') or a non-social (neutral tone) critical stimulus (CS) was unexpectedly presented under high and low load. For the social CS both groups continued to show high awareness rates as load increased. Awareness rates for the non-social stimulus were reduced when load increased for the TD, but not the ASD group. The findings indicate enhanced capacity for non-social stimuli in ASD compared to TD, and a special attentional status for social stimuli in the TD group.
本研究考察了增加视觉感知负荷对自闭症谱系障碍（ASD，n=63）和典型发育（TD，n=62）青少年对社会和非社会刺激的听觉意识的影响。使用非注意聋范式，在高负荷和低负荷下意外呈现具有社会意义的（“嗨”）或非社会（中性音调）关键刺激（CS）。对于社会 CS，两组随着负荷的增加继续表现出高意识率。对于 TD 组，当负荷增加时，非社会刺激的意识率降低，但 ASD 组则不然。研究结果表明，与 TD 相比，ASD 对非社会刺激的容量增强，而 TD 组对社会刺激则具有特殊的注意力状态。
