Relatively little is known about the time course of access to the lexical representations of verbs in agrammatic aphasia and its effects on the prediction and integration of the verb's arguments. The present study used visual-world eyetracking to test whether verb meaning can be used by agrammatic aphasic individuals to predict and facilitate the integration of a subsequent noun argument. Nine adults with agrammatic aphasia and ten age-matched controls participated in the study. In Experiment 1, participants viewed arrays of four objects (e.g., jar, plate, stick, pencil) while listening to sentences containing either a restrictive verb that was semantically compatible only with the target object or an unrestrictive verb compatible with all four objects (e.g., Susan will open/break the jar). For both participant groups, the restrictive condition elicited more fixations to the target object immediately after the verb. Experiment 2 differed from Experiment 1 in that the auditory sentences presented were incomplete (e.g., Susan will open/break the…). For controls, restrictive verbs elicited more target fixations immediately after the verb; however, the effects of verb type were noted downstream from the verb for the aphasic listeners. The results suggest that individuals with agrammatic aphasia have preserved ability to use verb information to facilitate integration of overt arguments, but prediction of upcoming arguments is impaired. Impaired lexical-semantic prediction processes may be caused by damage to the left inferior frontal gyrus, which has been argued to support higher-level lexical processes.

动词意义对失语症词汇整合的影响:来自眼球追踪的证据

对于语法性失语症中动词词汇表征的获取时间过程及其对动词论点的预测和整合的影响,我们知之甚少。本研究使用视觉世界眼动追踪来测试语法失语症患者是否可以使用动词含义来预测和促进后续名词论证的整合。九名患有语法性失语症的成年人和十名年龄匹配的对照参加了这项研究。在实验 1 中,参与者在听包含仅与目标对象语义兼容的限制性动词或与所有四个对象兼容的非限制性动词(例如,苏珊将打开/打破罐子)。对于两个参与者群体,限制性条件在动词之后立即引起对目标对象的更多注视。实验 2 与实验 1 的不同之处在于呈现的听觉句子是不完整的(例如,苏珊会打开/打破……)。对于对照,限制性动词在动词后立即引起更多的目标注视;然而,对于失语症听众来说,动词类型的影响在​​动词的下游被注意到。结果表明,语法性失语症患者保留了使用动词信息促进公开论点整合的能力,但对即将发生的论点的预测会受损。受损的词汇语义预测过程可能是由左额下回受损引起的,这被认为支持更高级别的词汇过程。
