The current study investigates the influence of phonological neighborhoods on the accuracy of speech production in aphasia by examining errors produced in both spontaneous and structured speech tasks. Characteristics of the phonological neighborhoods of spontaneously produced aphasic errors are compared to the neighborhood characteristics of correctly produced targets in a picture description task. Accuracy of picture naming is also examined with reference to the phonological neighborhood characteristics of the stimuli. Results show that frequency of occurrence and neighborhood density play a facilitative role in speech production, replicating findings from recent studies with normal subjects. It is argued that the results are most parsimoniously explained within an interactive activation framework of lexical access.
本研究通过检查自发和结构化言语任务中产生的错误，探讨语音邻域对失语症患者言语产生准确性的影响。将自发产生的失语症错误的语音邻域特征与图片描述任务中正确产生的目标的邻域特征进行比较。还参照刺激的语音邻域特征检查图片命名的准确性。结果表明，出现频率和邻域密度在言语产生中起促进作用，这与最近对正常受试者的研究结果一致。有人认为，在词汇通达的交互式激活框架内，这些结果得到了最简洁的解释。
