Each of 4 groups (N: 5) of normal-hearing young adults responded to the consonant-vowel-consonant-vowel Nonsense Syllable Test (Edgerton and Danhauer, 1979). Groups I and II on any one day for 5 consecutive days received one presentation of both Lists A and B at 16 and at 56 db re individual SRT, with (Group II) or without (Group I) visual reinforcement as to the correctness of the response. Groups III and IV received 15 randomizations of List A (non-reinforced) in a single session at 16 or 56 db SL, respectively. S's were tested individually diotically; verbal responses were phonetically transcribed using both audio and visual cues, and were scored phonetically. There were no significant differences in means between Groups I vs II as a result of reinforcement, but differences were noted in both groups for presentation levels and trials (days). No practice effects were noted in Groups III and IV. The NST may be used for multiple administrations within a single session, as in deriving performance-intensity functions, or in hearing aid evaluations, without biases due to practice.
4组(每组n = 5)听力正常的年轻成年人对辅音-元音-辅音-元音无意义音节测试(埃杰顿和丹豪尔,1979年)做出反应。第一组和第二组在任何一天连续5天,分别在高于个体言语接受阈16分贝和56分贝的强度下,各接受一次A表和B表的测试,其中第二组有(对反应正确性的)视觉强化,第一组没有。第三组和第四组分别在高于听阈级16分贝或56分贝的强度下,在单次测试中接受A表的15次随机测试(无强化)。受试者通过双耳分别接受测试;言语反应通过音频和视觉线索进行语音转录,并进行语音评分。强化与否导致第一组和第二组之间的均值无显著差异,但两组在测试强度和测试次数(天数)方面存在差异。第三组和第四组未发现练习效应。无意义音节测试可在单次测试中多次使用,如用于推导性能-强度函数或进行助听器评估,而不会因练习产生偏差。
