对计算机辅助言语知觉评估(Caspa)测试中记录的刺激进行表间等价性和短期练习效果评估。对20名听力正常的成年人进行了20个列表，每个列表包含10个辅音-元音-辅音单词。这些列表是在50dBSPL(LEQ)下，在存在频谱匹配的稳态噪声(55dBSPL)的情况下提供的。第一个列表的音素再认分数显著低于第二个列表至第二十个列表，表明练习效果不大。其中4个列表(3、6、7和16)的音素分数显著高于其余16个列表的分数约10个百分点。消除列表间差异的影响将基于单一列表的测试分数的95%可信区间从18.4个百分点降低到16.1个百分点。虽然列表间的差异对置信限只有很小的影响，但一些临床医生可能希望通过将列表3、6、7和16排除在测试之外来消除它们。这里观察到的练习效果可以通过在开始测试之前执行一个10个单词的练习列表来消除。
Interlist equivalency and short-term practice effects were evaluated for the recorded stimuli of the Computer-Assisted Speech Perception Assessment (CASPA) Test. Twenty lists, each consisting of 10 consonant-vowel-consonant words, were administered to 20 adults with normal hearing. The lists were presented at 50 dB SPL (Leq) in the presence of spectrally matched steady-state noise (55 dB SPL Leq). Phoneme recognition scores for the first list presented were significantly lower than for the second through the twentieth list presented, indicating a small practice effect. Phoneme scores for 4 of the lists (3, 6, 7, and 16) were significantly higher than scores for the remaining 16 lists by approximately 10 percentage points. Eliminating the effects of interlist differences reduced the 95 percent confidence interval of a test score based on a single list from 18.4 to 16.1 percentage points. Although interlist differences have only a small effect on confidence limits, some clinicians may wish to eliminate them by excluding lists 3, 6, 7, and 16 from the test. The practice effect observed here can be eliminated by administering one 10-word practice list before beginning the test.
