目的：检查习得年龄 (AOA) 和习得渠道（AC；印刷体、口语、手语）的主观估计对感知体验差异显着的人群内部和人群之间单词接触差异的敏感性。方法：50 名早发性耳聋参与者和 50 名听力正常的参与者根据主观 AOA 和 AC 评分了 175 个单词。使用标准化阅读和词汇测试收集其他数据。结果：早发性耳聋参与者比听力正常的参与者（M = 8.5 年）认为单词学习晚（M = 10 年），F (1, 99) = 28.59，p < .01。 AOA 的组平均项目评分在各组之间高度相关 (r = .971)，并且与习得的规范顺序高度相关（聋人：r = .950，听力：r = .946）。各组的 AC 评分不同（听力：印刷= 30％，口语= 70％，手语= 0％；聋人：印刷= 45％，口语= 38％，手语= 17％）。结论：主观AOA和AC测量对组间和组内词汇体验差异很敏感。结果表明，这些主观测量可以作为词汇发展直接测量的代理，用于对患有语前发作性耳聋的成人词汇知识的研究。
Purpose: Sensitivity of subjective estimates of age of acquisition (AOA) and acquisition channel (AC; printed, spoken, signed) to differences in word exposure within and between populations that differ dramatically in perceptual experience was examined.Methods: Fifty participants with early-onset deafness and 50 participants with normal hearing rated 175 words in terms of subjective AOA and AC. Additional data were collected using a standardized test of reading and vocabulary.Results: Participants with early-onset deafness rated words as learned later (M = 10 years) than did participants with normal hearing (M = 8.5 years), F (1, 99) = 28.59, p < .01. Group-averaged item ratings of AOA were highly correlated across the groups (r = .971) and with normative order of acquisition (deaf: r = .950, hearing: r = .946). The groups differed in their ratings of AC (hearing: printed = 30%, spoken = 70%, signed = 0%; deaf: printed = 45%, spoken = 38%, signed = 17%).Conclusions: Subjective AOA and AC measures are sensitive to between- and within-group differences in word experience. The results demonstrate that these subjective measures can be applied as proxies for direct measures of lexical development in studies of lexical knowledge in adults with prelingual onset deafness.
