Preference for social gaze as well as the percentage occurrence of social gaze, nonverbal social avoidance, and nonverbal repetitive behaviors were examined in autistic and nonautistic prepubertal males with the fragile X syndrome (fra[X]) during social interaction with a parent or stranger. Comparison groups were nonhandicapped, Down syndrome, atypical pervasive developmental disorder, and autistic males. The subjects with fra(X) and the nonhandicapped and Down syndrome control subjects discriminated parent from stranger as evidenced by their avoidance behavior. The overall percentage of avoidance was higher, however, for both parent and stranger, among the males with fra(X). Autistic and atypical groups without fra(X) failed to discriminate parent from stranger in their avoidance behavior. Possible explanations for these group differences in terms of language level or degree of language demand were ruled out. Implications for research concerning the relations among fra(X), autism, and mental retardation were discussed.
在患有脆性X综合征（fra[X]）的青春期前自闭症和非自闭症男性与父母或陌生人进行社交互动时，研究了他们对社交注视的偏好以及社交注视、非言语社交回避和非言语重复行为的出现百分比。对照组为非残疾、唐氏综合征、非典型广泛性发育障碍和自闭症男性。患有fra(X)的受试者以及非残疾和唐氏综合征对照受试者通过回避行为区分了父母和陌生人。然而，在患有fra(X)的男性中，无论是对父母还是对陌生人，总体回避百分比都更高。没有fra(X)的自闭症和非典型组在回避行为中未能区分父母和陌生人。排除了根据语言水平或语言需求程度对这些组间差异的可能解释。讨论了关于fra(X)、自闭症和智力迟钝之间关系的研究意义。
