If the members of a functional response class occur in a predictable order, a response-class hierarchy is said to exist. Although this topic has received some attention in the applied literature, it remains relatively understudied. The purpose of the current investigation was to develop an analogue model of a response-class hierarchy. Children with and without developmental disabilities were first taught three responses in an attempt to develop a functional response class ordered along the dimension of response effort (Experiment 1). Following response-class development, an extinction analysis was used to determine whether the responses were hierarchically related (Experiment 2). Results of Experiment 1 indicated that a functional response class was developed, and that there was a relation between response rate and effort for the established response class. Results of Experiment 2 indicated that a response-class hierarchy existed within the previously developed response classes for 3 of 4 participants.
如果功能性反应类别的成员按可预测的顺序出现，则称存在反应类别层次结构。尽管该主题在应用文献中已受到一些关注，但仍相对研究不足。当前调查的目的是开发一个反应类别层次结构的模拟模型。首先对有和没有发育障碍的儿童进行三种反应的训练，试图建立一个沿反应努力维度排序的功能性反应类别（实验1）。在反应类别形成之后，采用消退分析来确定这些反应是否具有层次关系（实验2）。实验1的结果表明已建立了一个功能性反应类别，并且已建立的反应类别在反应率和努力程度之间存在关联。实验2的结果表明，在之前为4名参与者中的3名所建立的反应类别中存在反应类别层次结构。
