The present study was designed to provide empirical evidence for an assumed order sequence of five behavioral strategies in 75 severely and profoundly retarded adults. A behavioral strategy was defined as a set of task-related behaviors each of which is controlled by the same stimulus properties of the materials. Four sets of tasks were used to measure four of the five strategies. Multiple presentation modes were employed to enhance the Ss' understanding of the demand characteristics of the tasks. A scalogram analysis revealed that the four sets of items met the requirements for a cumulative scale. Additional analyses were performed to identify individual items measuring a specific behavioral strategy. The obtained results indicated that most items measured one strategy although not always the one for which they were designed. The additional value of the described classification system over other, more traditional measures, is discussed.
本研究旨在为75名重度和极重度智力迟钝成年人的五种行为策略的假定顺序提供实证依据。行为策略被定义为一组与任务相关的行为，其中每一种行为都受材料相同刺激特性的控制。四组任务用于测量五种策略中的四种。采用多种呈现模式来增强受试者对任务需求特征的理解。量表分析表明，这四组项目符合累积量表的要求。还进行了额外的分析，以识别测量特定行为策略的单个项目。所得结果表明，大多数项目测量的是一种策略，尽管并不总是它们所设计测量的那种策略。文中讨论了所描述的分类系统相对于其他更传统测量方法的附加价值。
