This study was designed to examine the relationship between cognitive functioning of Down's syndrome subjects as measured by the Bayley Scales of Infant Development and their symbolic play level. Subjects ranged in chronological age from 20 to 53 months and in mental age from 12 to 26 months. Each child was seen at home with the mother or primary caretaker present. A 1/2-hour play session was videotaped, followed by administration of the Bayley Mental Scale and Infant Behavior Record. Analysis of play behavior supported a 4-level scale. Symbolic play level was more highly correlated with mental age than with chronological age. Performance on the Infant Behavior Record was also highly correlated with symbolic play level.
本研究旨在通过贝利婴儿发展量表测量唐氏综合征受试者的认知功能与其象征性游戏水平之间的关系。受试者的实际年龄在20至53个月之间，心理年龄在12至26个月之间。每个孩子在母亲或主要照顾者在场的情况下在家中接受观察。进行了一场半小时的游戏环节并录像，随后进行贝利智力量表和婴儿行为记录测试。对游戏行为的分析支持了一个四级量表。象征性游戏水平与心理年龄的相关性高于与实际年龄的相关性。婴儿行为记录的表现也与象征性游戏水平高度相关。
