This study examined gestalt perception in high-functioning autism (HFA) and its relation to tasks indicative of local visual processing. Data on of gestalt perception, visual illusions (VI), hierarchical letters (HL), Block Design (BD) and the Embedded Figures Test (EFT) were collected in adult males with HFA, schizophrenia, depression and normative controls. Individuals with HFA processed gestalt stimuli less in accord with gestalt laws, particularly regarding the principle of similarity. Gestalt processing correlated positively with global processing of the HL. EFT and BD performance correlated negatively with VI susceptibility in HFA. All clinical groups succumbed less to VI than the normative sample. Results suggest decreased gestalt perception in HFA, being associated with a more general local visual processing bias.
本研究考察了高功能自闭症（HFA）患者的格式塔知觉及其与局部视觉加工相关任务的关系。收集了患有HFA、精神分裂症、抑郁症的成年男性以及正常对照组在格式塔知觉、视觉错觉（VI）、分层字母（HL）、积木设计（BD）和镶嵌图形测验（EFT）方面的数据。HFA患者对格式塔刺激的加工不太符合格式塔法则，尤其是在相似性原则方面。格式塔加工与HL的整体加工呈正相关。在HFA患者中，EFT和BD表现与VI易感性呈负相关。所有临床组比正常样本更不易受VI影响。结果表明，HFA患者的格式塔知觉下降，这与更普遍的局部视觉加工偏向有关。
