There is a need for practical methods of reinforcer assessment that systematically track ongoing changes in clients' preferences. In this study, the effects of a time-efficient reinforcer assessment package were evaluated in a multiple baseline across 3 preschoolers with autism, comparing individualized item selections by experienced teachers with children's presession preferences for items of various sensory qualities. Systematic assessment of children's reinforcers for correct responding virtually eliminated nontargeted maladaptive behaviors, as well as yielding expected improvements in accuracy. The powerful side-effects of potent reinforcers underline the importance of increased attention to reinforcer assessment in research and practice.
需要有切实可行的强化物评估方法,以便系统地跟踪服务对象偏好的持续变化。在本研究中,对一种省时的强化物评估方案的效果进行了评估,该方案采用多基线设计,涉及3名患有自闭症的学龄前儿童,将经验丰富的教师进行的个性化项目选择与儿童课前对各种感官特性项目的偏好进行比较。对儿童正确反应的强化物进行系统评估,实际上消除了非目标性的适应不良行为,并在准确性方面产生了预期的改善。强效强化物的强大副作用凸显了在研究和实践中加强对强化物评估关注的重要性。
