与失语症患者和非脑损伤说话者的主语亲属相比，跨语言处理客体亲属的需求更大，这一发现在相对化的最低限度方法中得到了解释。基于这一解释，这种不对称性被归因于在客体亲属中移动的元素与其提取位置之间的一个元素，而不是在主体亲属中。此外，已经提出，如果介入的元素和移动的元素在其内部特征结构上不同，则有利于对象关系的处理。本研究通过将视觉世界眼球跟踪方法与听觉指称识别任务相结合，在德语失语症患者和一组对照参与者中调查了这些预测。我们的结果支持相对化的最小化方法。具体地说，特征的清晰度在失语症中被显示为调节效应的发生。我们认为，由于加工能力的降低，失语症患者需要更高程度的特征相异度来区分客体亲属中的移动者和介入者，以克服他们的句法缺陷。(C)2017爱思唯尔有限公司。保留所有权利。
The cross-linguistic finding of greater demands in processing object relatives as compared to subject relatives in individuals with aphasia and non-brain-damaged speakers has been explained within the Relativized Minimality approach. Based on this account, the asymmetry is attributed to an element intervening between the moved element and its extraction site in object relatives, but not in subject relatives. Moreover, it has been proposed that processing of object relatives is facilitated if the intervening and the moved elements differ in their internal feature structure. The present study investigates these predictions in German-speaking individuals with aphasia and a group of control participants by combining the visual world eye-tracking methodology with an auditory referent identification task. Our results provide support for the Relativized Minimality approach. Particularly, the degree of featural distinctness was shown to modulate the occurrence of the effects in aphasia. We claim that, due to reduced processing capacities, individuals with aphasia need a higher degree of featural dissimilarity to distinguish the moved from the intervening element in object relatives to overcome their syntactic deficit.
