语义可逆的主动和被动语态句子的理解进行了测试，在一个定时的句子/图片验证任务。三套六个动词被确定为合并相关的分配名词的主题角色的代理意义的不同功能。正常对照组被试的反应时表现出动词组效应，在预测方向上，动词组之间的效应显著。一组没有句子理解障碍的失语症患者也表现出了动词集的显着效果，尽管反应时间长且变化不定。一组患有可逆性理解障碍的患者在筛选任务中表现出较弱的效果，主要是因为使用了忽略句子动词的一致反应偏差。主动/被动理解的实验治疗进行了两个后者的患者，一个病人达到上限后测试，和其他表现出显着的改善，但表现出残余的理解问题，表明跨动词集的差异。结果支持动词意义对正常和失语症句子理解的关键重要性。
Comprehension of semantically reversible active and passive voice sentences was tested in a timed sentence/picture verification task. Three sets of six verbs were identified that incorporated different features of meaning relevant to the assignment of nouns to the thematic role of agent. Normal control subjects showed an effect of verb set on their response times, with significant effects between sets in the predicted direction. A group of aphasic patients without sentence comprehension disorder also showed a significant effect of verb set despite long and variable response times. A group of patients with reversible comprehension disorder in screening tasks showed weaker effects, primarily because of the use of consistent response biases that ignored the sentence verb. An experimental treatment of active/passive comprehension was conducted with two of these latter patients; one patient reached ceiling in post-testing, and the other showed significant improvement but demonstrated residual comprehension problems that indicated differences across verb sets. Results support the critical importance of verb meaning to normal and aphasic sentence comprehension.
