The present study examined temporal characteristics of monosyllabic, bisyallabic, and trisyllabic words in Thai to evaluate timing control at the word level in brain-damaged patients. Subjects included young and old normal adults, right hemisphere patients, and left hemisphere nonfluent and fluent aphasic patients. Utterances were produced at a conversational speaking rate. Results indicated that, on an absolute or relative measurement scale, magnitude of the shortening effect on nonfinal syllables in polysyllabic words was significantly smaller in left nonfluent aphasics than in other groups. In trisyllabic words, duration of the penultimate syllable for left fluent aphasics was also significantly longer than that of normals. Left nonfluent and fluent aphasics were significantly more variable than other speakers in their production of bisyllabic and trisyllabic words. Findings are discussed in relation to issues pertaining to the nature of timing deficits in nonfluent and fluent aphasic patients.
本研究考察了泰语中单音节、双音节和三音节词的时间特征，以评估脑损伤患者在词层面的时间控制。受试者包括年轻和年长的正常成年人、右半球患者以及左半球非流畅性和流畅性失语症患者。言语以对话语速产生。结果表明，在绝对或相对测量尺度上，左半球非流畅性失语症患者多音节词中非末音节的缩短效应幅度显著小于其他组。在三音节词中，左半球流畅性失语症患者倒数第二个音节的时长也显著长于正常人。左半球非流畅性和流畅性失语症患者在双音节和三音节词的产出方面比其他说话者的变异性显著更大。研究结果围绕非流畅性和流畅性失语症患者时间缺陷的本质相关问题展开讨论。
