This study extends an operant methodology for the analysis of variables which control aberrant responses displayed by mentally handicapped people. The proportion of time spent in individual, stereotyped topographies by three profoundly mentally handicapped subjects was observed by momentary time-sampling whilst they were repeatedly exposed to four analogue environments: Alone, Social Disapproval, Academic Demand and Unstructured Play. Two of the three subjects showed replicable effects of the analogue environments. One subject showed evidence of an interaction between stereotyped topography and type of analogue environment. This study shows that the operant methodology of Iwata et al. (1982), originally developed with self-injurious responses, can be successfully refined and extended to the analysis of a wider range of aberrant topographies.
本研究扩展了一种操作性方法，用于分析控制智力障碍者所表现出的异常反应的变量。通过瞬间时间抽样观察了三名重度智力障碍受试者在个体、刻板行为模式中所花费的时间比例，在此期间，他们反复接触四种模拟环境：独处、社会不认可、学业要求和无组织游戏。三名受试者中有两名显示出模拟环境的可重复效应。一名受试者显示出刻板行为模式与模拟环境类型之间存在相互作用的证据。本研究表明，Iwata等人（1982年）最初用于自我伤害反应的操作性方法可以成功地得到完善并扩展，以分析更广泛的异常行为模式。
