被诊断为自闭症的儿童和发育正常的儿童，在年龄和一般能力上相匹配，在两个独立的实验中进行了一系列视觉搜索任务的测试。自闭症儿童在困难的视觉搜索任务中表现得比正常发育的儿童好。无论目标是由单个特征还是由多个特征的组合唯一定义，只要天花板效应不掩盖差异，都会出现这种结果。自闭症患者的上级视觉搜索表现可以被视为类似于自闭症患者的增强独特项目检测的其他报告。独特的项目检测自闭症的机制进行了讨论，提出参与正常的视觉搜索性能。
Children with a diagnosis of autism and normally developing children, matched for age and general ability, were tested on a series of visual search tasks in 2 separate experiments. The children with autism performed better than the normally developing children on difficult visual search tasks. This result occurred regardless of whether the target was uniquely defined by a single feature or a conjunction of features, as long as ceiling effects did not mask the difference. Superior visual search performance in autism can be seen as analogous to other reports of enhanced unique item detection in autism. Unique item detection in autism is discussed in the light of mechanisms proposed to be involved in normal visual search performance.
