In recent years, functional analysis methods have been extended to classroom settings; however, research has not evaluated the extent to which consequences presented during functional analysis are associated with problem behavior under naturalistic classroom conditions. Therefore, the purpose of this study was to determine whether the social consequences commonly manipulated in functional analyses occur in typical preschool classrooms. A total of 14 children attending preschool programs participated in the study. Data were collected on the occurrence of antecedent events (e.g., presentation of tasks), child behaviors (e.g., aggression), and teacher responses (e.g., delivery of attention). The probability of various teacher responses given child behavior was then calculated and compared to the response-independent probabilities of teacher responses. Attention was found to be the most common classroom consequence (100% of children), followed by material presentation (79% of children), and escape from instructional tasks (33% of children). Comparisons of conditional and response-independent probabilities showed that the probability of teacher attention increased given the occurrence of problem behavior for all children, suggesting that a contingency existed between these two events. Results suggest that functional analyses that test the effects of attention, escape, and access to materials on problem behavior may be appropriate for preschool settings.
近年来,功能分析方法已扩展到课堂环境;然而,研究尚未评估功能分析过程中呈现的后果与自然主义课堂条件下的问题行为之间的关联程度。因此,本研究的目的是确定功能分析中通常操纵的社会后果是否出现在典型的学前课堂中。共有14名参加学前教育项目的儿童参与了该研究。收集了关于先行事件(如任务呈现)、儿童行为(如攻击行为)和教师反应(如给予关注)发生情况的数据。然后计算了给定儿童行为时各种教师反应的概率,并将其与教师反应的独立于反应的概率进行比较。结果发现,关注是最常见的课堂后果(100%的儿童),其次是材料呈现(79%的儿童),以及逃避教学任务(33%的儿童)。条件概率和独立于反应的概率的比较表明,对于所有儿童,问题行为发生时教师给予关注的概率增加,这表明这两个事件之间存在一种偶然性。结果表明,测试关注、逃避和获得材料对问题行为影响的功能分析可能适用于学前教育环境。
