认知系统的一个基本任务是优先处理行为相关的感官输入，而不考虑不相关的输入。在一项对神经型参与者（n = 179）的研究中，我们利用了一个简短的侧翼干扰任务，同时改变视觉显示的感知负荷。通常，增加感知负载（即，具有更大数量的搜索项）减少了来自竞争的外围干扰物的干扰。我们发现，个人得分高于平均水平的自闭症谱系商（AQ）表现出更强的干扰，在高知觉负荷比个人低于平均AQ分数。这与最近在患有自闭症谱系疾病的个体中的发现一致，并支持自闭症大脑的认知方式反映在整个人群中更广泛的表型中的观点。
A fundamental task of the cognitive system is to prioritize behaviourally relevant sensory inputs for processing at the expense of irrelevant inputs. In a study of neurotypical participants (n = 179), we utilized a brief flanker interference task while varying the perceptual load of the visual display. Typically, increasing perceptual load (i.e., with greater numbers of search items) reduces interference from a competing peripheral distractor. We show that individuals who score above average on the Autism Spectrum Quotient (AQ) show stronger interference at high perceptual load than individuals with below-average AQ scores. This is consistent with recent findings in individuals with autism spectrum conditions, and supports the idea that the cognitive style of the autistic brain is reflected in a broader phenotype across the population.
