A functional analysis for a boy with Down syndrome and autism suggested that vocal stereotypy was maintained by automatic reinforcement. The analysis also showed that instructions and noncontingent attention suppressed vocal stereotypy. A treatment package consisting of noncontingent attention, contingent demands, and response cost effectively reduced vocal stereotypy. The treatment package remained effective even when noncontingent attention was removed, making the procedure easier to implement. Also, the presence of the therapist in the room with the participant was faded systematically. After completion of fading, vocal stereotypy remained low during conditions similar to the no-consequence phase of the functional analysis.
对一名患有唐氏综合征和自闭症的男孩进行的功能分析表明，发声刻板行为是由自动强化维持的。该分析还表明，指令和非依随注意可抑制发声刻板行为。由非依随注意、依随要求和反应代价组成的治疗方案有效地减少了发声刻板行为。即使去除了非依随注意，该治疗方案仍然有效，使得该程序更易于实施。此外，治疗师与参与者在房间里的存在被系统地淡化。淡化完成后，在类似于功能分析的无结果阶段的条件下，发声刻板行为仍然很低。
