The influence of three features of manual signs (iconicity, motoric complexity, linguistic function) on their successful acquisition by aphasic subjects was investigated. 12 severe chronic aphasic subjects were presented 37 signs in a training program for the production of manual signs. Analysis indicates that the three signs features affected the successful acquisition of signs. As a group the subjects acquired a larger percentage of high and medium iconic than of low iconic signs; a larger percentage of low and medium motorically complex signs than high; and a larger percentage of verb than noun or adjective signs. The implications of these findings with regard to selecting a manual sign vocabulary for training are discussed.
研究了手势语的三个特征（象似性、动作复杂性、语言功能）对失语症患者成功习得手势语的影响。在一个用于手势语产出的训练项目中，向12名严重慢性失语症患者展示了37种手势。分析表明，这三个手势特征影响了手势的成功习得。总体而言，患者习得的高象似性和中等象似性手势的比例高于低象似性手势；低动作复杂性和中等动作复杂性手势的比例高于高动作复杂性手势；动词手势的习得比例高于名词或形容词手势。讨论了这些发现对于选择用于训练的手势语词汇的意义。
