The current study examined eye movement control in autistic (ASD) children. Simple targets were presented in isolation, or with central, parafoveal, or peripheral distractors synchronously. Sixteen children with ASD (47-81 months) and nineteen age and IQ matched typically developing children were instructed to look to the target as accurately and quickly as possible. Both groups showed high proportions (40%) of saccadic errors towards parafoveal and peripheral distractors. For correctly executed eye movements to the targets, centrally presented distractors produced the longest latencies (time taken to initiate eye movements), followed by parafoveal and peripheral distractor conditions. Central distractors had a greater effect in the ASD group, indicating evidence for potential atypical voluntary attentional control in ASD children.
本研究考察了自闭症（ASD）儿童的眼球运动控制。简单的目标单独呈现，或与中央、旁中央或外周分心物同步呈现。16 名 ASD 儿童（47-81 个月）和 19 名年龄和智商匹配的正常发育儿童被指示尽可能准确和快速地注视目标。两组儿童的旁中央和外周分心物的扫视错误率都很高（40%）。对于正确执行的眼动到目标，中央呈现的分心物产生的潜伏期最长（开始眼动所需的时间），其次是旁中央和外周分心物条件。中央分心物对 ASD 组的影响更大，表明 ASD 儿童可能存在非典型的自愿注意力控制。
