Previous studies have found reduced leftward bias of facial processing in individuals with Autism Spectrum Disorder (ASD). However, it is not clear whether they manifest a leftward bias in general visual processing. To shed light on this issue, the current study used the manual line bisection task to assess children 5 to 15 years of age with ASD as well as typically developing (TD) children. Results showed that children with ASD, similar to TD children, demonstrate a leftward bias in general visual processing, especially for bisecting long lines (≧ 80 mm). In both groups, participant performance in line bisection was affected by the hand used, the length of the line, the cueing symbol, and the location of the symbol. The ASD group showed a rightward bias when bisecting short lines (30 mm) with their left hands, which slightly differed from the TD group. These results indicate that while ASD individuals and TD individuals share a similar leftward bias in general visual processing, when using their left hands to bisect short lines, ASD individuals may show an atypical bias pattern.
先前的研究发现，自闭症谱系障碍（ASD）个体的面部处理存在左偏减少。然而，目前尚不清楚他们是否在一般视觉处理中表现出左偏。为了阐明这个问题，本研究使用手动线二分任务评估了 5 至 15 岁的 ASD 儿童以及典型发育（TD）儿童。结果表明，ASD 儿童与 TD 儿童一样，在一般视觉处理中表现出左偏，尤其是在平分长线段（≧80mm）时。在两组中，参与者在线二分任务中的表现受到使用的手、线的长度、提示符号以及符号位置的影响。当 ASD 组用左手平分 30mm 的短线时，表现出右偏，这与 TD 组略有不同。这些结果表明，尽管 ASD 个体和 TD 个体在一般视觉处理中具有相似的左偏，但当他们用左手平分短线时，ASD 个体可能表现出异常的偏倚模式。
