To investigate the relationship between success in the acquisition of signs and the degree of severity of aphasic impairment 12 chronic severely aphasic subjects participated in a training program for the acquisition of a vocabulary of manual signs. The results demonstrate a clear and significant relationship between severity of aphasia and success in the acquisition and generalization of manual signs. The results also indicate that there may be a threshold of severity of aphasia below which acquisition is negligible. Discussion is presented relative to the theoretical, clinical, and methodological implications of these findings.
为了研究手势习得的成功与失语症损伤严重程度之间的关系，12名慢性重度失语症患者参与了一项手势词汇习得的训练项目。结果表明，失语症的严重程度与手势习得及泛化的成功之间存在明确且显著的关系。结果还表明，可能存在一个失语症严重程度的阈值，低于该阈值，习得效果可忽略不计。文中针对这些发现的理论、临床和方法学意义进行了讨论。
