A total of 24 institutionalized retarded children, 12 mongoloid (Down's syndrome) and 12 nonmongoloid, were observed in dyadic interaction with peers in a free-play situation, and a number of specific peer-social and non-social behaviors were recorded as they occurred. Differences between mongoloid and nonmongoloid Ss were most apparent on several social behavior categories which support the stereotypic conception of mongoloids as more sociable, gregarious, etc. Differences were most apparent for the mongoloid boys. The possible influence of tranquilizer drugs and cottage placements on the observed differences was discussed.
共有24名被收容的智障儿童参与了此次研究，其中12名患有唐氏综合征（先天愚型），另外12名没有患唐氏综合征。在自由玩耍情境下，观察他们与同伴的二元互动，并记录下出现的一些特定的同伴社交和非社交行为。患唐氏综合征和未患唐氏综合征的受试者之间的差异在几个社交行为类别上最为明显，这些差异支持了将患唐氏综合征者视为更善于社交、群居等的刻板观念。这种差异在患唐氏综合征的男孩中最为明显。文中还讨论了镇静药物和家庭安置对观察到的差异可能产生的影响。
