本研究旨在探讨特殊语言障碍儿童词汇学习障碍的成因。参与者包括40名7-8岁的参与者，其中一半被诊断为SLI，另一半具有正常的语言技能。我们测试了语音信息的初始编码对单词学习的贡献以及与长期记忆的联系的假设。儿童参加了一个基于计算机的快速映射任务，操纵单词长度和语音定位概率来解决的假设。这项任务有一个承认和生产的组成部分。使用混合ANOVA和事后检验分析数据。结果表明，SLI儿童的主要问题是与初始编码，与有限的能力的影响。没有强有力的证据表明长期记忆的具体缺陷。我们能够确定哪些方面的词汇学习是最有问题的SLI儿童在快速映射。这些发现可能使临床医生将干预重点放在已知的薄弱领域。未来的方向包括将这些发现扩展到慢速映射场景。
The purpose of this study was to determine which factors contribute to the lexical learning deficits of children with Specific Language Impairment (SLI). Participants included 40 7-8-year old participants, half of whom were diagnosed with SLI and half of whom had normal language skills. We tested hypotheses about the contributions to word learning of the initial encoding of phonological information and the link to long-term memory. Children took part in a computer-based fast-mapping task which manipulated word length and phonotactic probability to address the hypotheses. The task had a recognition and a production component. Data were analyzed using mixed ANOVAs with post-hoc testing. Results indicate that the main problem for children with SLI is with initial encoding, with implications for limited capacity. There was not strong evidence for specific deficits in the link to long term memory. We were able to ascertain which aspects of lexical learning are most problematic for children with SLI in terms of fast-mapping. These findings may allow clinicians to focus intervention on known areas of weakness. Future directions include extending these findings to slow mapping scenarios.
