Unusually low voice volume was identified by teachers as a significant impediment to the academic and social progress of two preschool students. A simple operant shaping procedure was conducted by teachers to increase voice volume using a voice-activated apparatus with attractive visual display. Setting generalization of volume increases to the classroom was achieved and maintained at one- and four-month follow-ups.
教师们发现,异常低沉的音量严重阻碍了两名学龄前儿童在学业和社交方面的进步。教师们采用了一种简单的操作性塑造程序,使用带有吸引人的视觉展示的语音激活设备来提高音量。音量的增加在课堂环境中得到了泛化,并在1个月和4个月的随访中得以维持。
