Happé（1996）解释说，最近的一项发现表明，自闭症患者不易产生错觉，这是在较低水平的处理过程中，“中枢一致性较弱”的一种表现。我们用一种更精密的方法研究了这一现象。在实验1中，患有自闭症、自闭症综合征、中度学习困难和典型发育的个体调整了某些比较线和圆圈，使它们在四种视错觉中看起来大小相同。除了一个小的例外，自闭症和艾伯格综合征的参与者在幻觉条件下的判断中表现出系统性的偏见。这种程度与控制参与者没有什么不同。在第二个实验中，参与者对刺激做出口头判断的任务也得到了类似的发现。结果表明，自闭症患者视觉处理的低水平连贯性是完整的。
A recent finding that individuals with autism are not susceptible to illusions has been explained by Happé (1996) as a sign of "weak central coherence" at lower levels of processing. We investigated the phenomenon with a more sophisticated measure. In Experiment 1, individuals with autism, Asperger's syndrome, moderate learning difficulties, and typical development adjusted certain comparison lines and circles to make them appear to be the same size in four visual illusions. With a minor exception, the participants with autism and Asperger's syndrome evinced a systematic bias in their judgements in the illusion condition. The extent of this was no different from control participants. In a second experiment, a similar finding was obtained in a task where participants made verbal judgements about the stimuli. The results suggest that lower-level coherence in visual processing in autism is intact.
