作者们采用三择一程序成功地测定了儿童的听阈,所得到的结果支持了前人关于幼童听觉灵敏度偏低的观察,并提供了关于学习迟钝儿童听觉灵敏度偏低的证据。作者们共选择了5组受试对象:6岁和10岁的正常儿童组,6岁和10岁的学习迟钝的儿童组,每组各18人,以及成年人组,共4人。各儿童组每人用5天参加5轮测试,成年人组每人两天参加两轮测试。作者们所设计的三择一程序概述如下:在受试者的前面设一显示屏,可以分别显示“1”、
Using a one-of-three procedure, the authors successfully measured children’s hearing thresholds, and the results supported previous observations of under-sensitivity in young children and provided evidence of low hearing sensitivity in children with learning-impaired hearing. The authors selected five groups of subjects: normal children aged 6 and 10, unlearning children aged 6 and 10, 18 in each group, and 4 in adults. Each child group participated in 5 rounds of testing for 5 days per person, and the adult group participated in two rounds of testing for two days per person. The three options and one program that the authors designed are summarized as follows: A display is located in front of the subject, which can display “1”, "
