Abstract

We compared the effects of extinction (EXT) and fixed-time (FT) schedules as treatment for severe problem behavior displayed by 3 individuals with developmental disabilities. First, functional analyses identified the reinforcers maintaining aberrant behavior for all 3 individuals. Next, EXT and FT schedules were compared using a multielement design. During EXT, the reinforcer maintaining problem behavior was withheld. During FT, the reinforcers were presented response independently at preset intervals. Results showed that FT schedules were generally more effective than EXT schedules in reducing aberrant behavior. FT schedules may be used in situations when extinction-induced phenomena are problematic.

摘要

我们比较了消退(EXT)和固定时间(FT)程序作为治疗3名发育障碍个体所表现出的严重问题行为的效果。首先,功能分析确定了维持所有3名个体异常行为的强化物。接下来,使用多元素设计比较EXT和FT程序。在EXT期间,维持问题行为的强化物被扣留。在FT期间,强化物在预设间隔独立于反应呈现。结果表明,FT程序在减少异常行为方面通常比EXT程序更有效。当消退诱导的现象存在问题时,FT程序可用于相关情况。
