Nonambiguous idiom comprehension was assessed in 15 right brain-damaged (RBD) and 12 left brain-damaged (LBD) aphasic patients by means of a string-to-picture matching task. Idiom comprehension was found to be severely impaired with a bias toward literal interpretation. The RBD patients, though impaired, performed significantly better than LBD patients; their performance was correlated with visuospatial abilities and was significantly affected by lesion site. The results of this study suggest that the performance of RBD patients in the comprehension of idiomatic sentences may be affected by (a) an involvement of the frontal lobe and/or (b) visuospatial deficits that may impair their performance on the picture-matching task.
通过一项字符串与图片匹配任务，对15名右脑损伤（RBD）失语患者和12名左脑损伤（LBD）失语患者的明确习语理解能力进行了评估。结果发现，习语理解能力严重受损，且偏向于字面解释。RBD患者虽有损伤，但表现明显优于LBD患者；他们的表现与视觉空间能力相关，且受损伤部位的显著影响。本研究结果表明，RBD患者在理解习语句子方面的表现可能受到以下因素的影响：（a）额叶的参与和/或（b）视觉空间缺陷，这可能会损害他们在图片匹配任务中的表现。
