该领域缺乏评估幼儿言语感知的有效且可靠的方法，导致在理解言语感知如何发展方面存在明显差距，并且用于评估幼儿感官辅助益处的临床工具有限。这项调查的目的是通过修改“更改/不更改”程序来评估幼儿的语音歧视。通过重复测量和析因设计相结合的方法，评估了听力正常的 2 岁和 3 岁儿童对声学上不同（“容易”）和相似（“困难”）语音对比的辨别能力。性能以 d’ 为单位进行衡量。使用重复测量方差分析、计划的事后测试和相关分析，检查了对比难度和年龄的影响，以及重测可靠性。在所有年龄段中，简单对比 (M=2.53) 的识别效果均优于硬对比 (M=1.72) (p < .0001)。年龄最大的儿童组 (M=3.13) 比最小的儿童组 (M=1.04; p < .0001) 和中年儿童组 (M=2.20; p = .037) 更好地辨别对比，而中年儿童组又比最小的儿童更好地辨别对比 (p = .010)。重测可靠性非常出色（r = .886，p < .0001）。几乎90%的孩子都达到了教学标准。绝大多数人表现出了使用修改后的程序进行测试并区分对比的能力。少数没有这样做的人年龄在 2.5 岁及以下。所实施的修改至少初步导致了对这一年轻儿童组的造影难度和年龄可靠且敏感的程序，这表明这些修改适合该年龄组。随着进一步的发展，该程序有望用于被认为在快速语音编码方面存在核心缺陷的临床人群，例如听力损失或特定语言障碍的儿童、阅读困难的儿童以及第二语言学习者。
Valid and reliable methods for assessing speech perception in toddlers are lacking in the field, leading to conspicuous gaps in understanding how speech perception develops and limited clinical tools for assessing sensory aid benefit in toddlers. The objective of this investigation was to evaluate speech-sound discrimination in toddlers using modifications to the Change/No-Change procedure. Normal-hearing 2- and 3-year-olds’ discrimination of acoustically dissimilar (“easy”) and similar (“hard”) speech-sound contrasts were evaluated in a combined repeated measures and factorial design. Performance was measured in d’. Effects of contrast difficulty and age were examined, as was test-retest reliability, using repeated measures ANOVAs, planned post-hoc tests, and correlation analyses. The easy contrast (M=2.53) was discriminated better than the hard contrast (M=1.72) across all ages (p < .0001). The oldest group of children (M=3.13) discriminated the contrasts better than youngest (M=1.04; p < .0001) and the mid-age children (M=2.20; p = .037), who in turn discriminated the contrasts better than the youngest children (p = .010). Test-retest reliability was excellent (r = .886, p < .0001). Almost 90% of the children met the teaching criterion. The vast majority demonstrated the ability to be tested with the modified procedure and discriminated the contrasts. The few who did not were 2.5 years of age and younger. The modifications implemented resulted, at least preliminarily, in a procedure that is reliable and sensitive to contrast difficulty and age in this young group of children, suggesting that these modifications are appropriate for this age group. With further development, the procedure holds promise for use in clinical populations who are believed to have core deficits in rapid phonological encoding, such as children with hearing loss or specific language impairment, children who are struggling to read, and second-language learners.
