The relation between abnormal stereotyped behaviors and abnormal focused affections (i.e., abnormally consistent preferences for specific objects, symbols, and/or physical locations) was examined in 20 children with developmental disabilities. Results indicated that (a) all children who exhibited abnormal focused affections exhibited stereotypies; (b) abnormal focused affections could be studied reliably in individuals with developmental disabilities through the use of direct time-sampling observations, naturalistic observations, and informant reports; and (c) developmental age was significantly related to the frequency of (and the number of different) stereotyped behaviors and the frequency of nonstereotyped (i.e., developmentally appropriate) behaviors exhibited across the sample. Results also provide preliminary support for the notion of a general stereotyped behavioral repertoire in individuals with developmental disabilities.
在20名发育障碍儿童中，研究了异常刻板行为与异常专注情感（即对特定物体、符号和/或物理位置异常一致的偏好）之间的关系。结果表明：（a）所有表现出异常专注情感的儿童都表现出刻板行为；（b）通过直接时间抽样观察、自然观察和信息提供者报告，可以在发育障碍个体中可靠地研究异常专注情感；（c）发育年龄与整个样本中表现出的刻板行为的频率（以及不同刻板行为的数量）和非刻板行为（即发育适当行为）的频率显著相关。研究结果还为发育障碍个体存在一般刻板行为模式这一观点提供了初步支持。
