The relationships existing between measures of disfluency and measures of word-retrieval ability in adult anomic aphasic and adult non-brain-damaged subjects were investigated. Subjects produced single-word naming responses for pictured stimuli consisting of objects, colors, and actions. The obtained number of correct naming responses and word-retrieval latency measurements were related to the number and types of disfluencies present in the subjects' connected speech samples. The major findings of the investigation include the following: (a) the anomic subject group presented significantly more disfluencies than did the nonaphasic group; (b) the number of disfluencies increased as word-retrieval difficulty increased for the anomic subjects; (c) when word-retrieval difficulty was measured by the number of correct responses those anomic subjects who tended to be most disfluent and to have the greatest word-retrieval difficulty also tended to have the highest proportions of those disfluencies most likely to be considered "stutterings" (part-word repetitions, vocal segregate repetitions, and prolongations) and the lowest proportions of hesitations; and (d) the proportion of stutterings increased as the total number of disfluencies increased for anomic and for nonaphasic subjects. Implications of results for testing of aphasic patients are discussed.
研究了成年失语症患者和成年非脑损伤受试者中言语不流畅性测量指标与词汇检索能力测量指标之间的关系。受试者对由物体、颜色和动作组成的图片刺激做出单字命名反应。获得的正确命名反应数量和词汇检索潜伏期测量结果与受试者连贯言语样本中出现的不流畅性数量和类型相关。该研究的主要发现如下：(a) 失语症受试者组比非失语症组表现出明显更多的不流畅性；(b) 对于失语症受试者，随着词汇检索难度的增加，不流畅性数量也增加；(c) 当通过正确反应数量来衡量词汇检索难度时，那些最容易出现言语不流畅且词汇检索难度最大的失语症受试者，其最有可能被视为“口吃”（单词部分重复、语音分隔重复和延长）的不流畅性比例也最高，而犹豫的比例最低；(d) 对于失语症和非失语症受试者，口吃的比例随着不流畅性总数的增加而增加。讨论了研究结果对失语症患者测试的意义。
