本研究以22名3岁至5岁的口吃儿童和22名非口吃儿童为被试，研究了习得年龄和重复启动对图片命名延迟和错误的影响。孩子们参加了一个计算机化的图片命名任务，他们命名的早期和晚期收购（AoA）的话在两个连续阶段的图片。研究结果显示，所有儿童的图片命名lavery和错误减少重复启动后，并在响应早期AoA的话相对于晚AoA的话。两个谈话者组的儿童的AoA和重复启动效应相似，但有一个例外。也就是说，CWS受益显着更多，在减少错误方面，比CWNS从重复启动晚AoA的话。此外，CWNS表现出显着的语言速度和词汇量之间的正相关，但CWS没有。这些研究结果表明：（a）CWS的语义-语音联系可能不如CWNS那么强，（B）现有的词汇测量方法可能不够敏感，无法在语言产生的词汇相关方面区分CWS和CWNS。教育目标：在阅读本文后，学习者将能够：（a）描述重复启动和词汇习得年龄在言语产生中的作用;（B）总结口吃儿童和不口吃儿童在计算机图形命名任务中的表现相似性和差异;以及（c）将本研究的结果与该领域以往的工作进行比较。(c)2008年爱思唯尔公司All rights reserved.
The effects of age of acquisition and repetition priming on picture naming latencies and errors were studied in 22 children who stutter (CWS) and 22 children who do not stutter (CWNS) between the ages of 3; 1 and 5;7. Children participated in a computerized picture naming task where they named pictures of both early and late acquired (AoA) words in two consecutive stages. Findings revealed that all children's picture naming latencies and errors were reduced following repetition priming and in response to early AoA words relative to late AoA words. AoA and repetition priming effects were similar for children in both talker groups, with one exception. Namely, CWS benefitted significantly more, in terms of error reduction, than CWNS from repetition priming for late AoA words. In addition, CWNS exhibited a significant, positive association between linguistic speed and measures of vocabulary, but CWS did not. These findings were taken to suggest that the (a) semantic-phonological connections of CWS may not be as strong as those of CWNS, and (b) existing lexical measures may not be sensitive enough to differentiate CWS from CWNS in lexically related aspects of language production.Educational objectives: After reading this article, the learner will be able to: (a) describe the effects of repetition priming and age of word acquisition in speech production; (b) summarize the performance similarities and differences of children who stutter and children who do not stutter on a computerized picture naming task; and (c) compare the results of the present study with previous work in this area.
