Quantitative as well as qualitative aspects of the social behaviour of a group of autistic children (n = 20) and a group of primary school children (n = 20) were studied by means of an ethological method. Principal components analysis of the behaviour protocols made clear that the social behaviour of autistic children was less well organized, lacked the factor 'inferential behaviour' and was characterized by a factor 'stereotyped behaviour'. Although the autistic group showed less eye contact than the normal group, no further signs of any particular social avoidance tendency was found.
采用行为学方法对一组自闭症儿童（n = 20）和一组小学生（n = 20）的社会行为的定量和定性方面进行了研究。对行为记录进行主成分分析表明，自闭症儿童的社会行为组织性较差，缺乏“推理行为”因素，其特征是存在“刻板行为”因素。尽管自闭症组的眼神交流比正常组少，但未发现任何特殊社会回避倾向的进一步迹象。
