There were two aims of this study. The first was to compare indirect inferencing abilities by nine right hemisphere brain-damaged (RHD) adults with 18 matched normal controls. The second purpose was to determine the best condition in which to present information to the RHD individuals for the purpose of forming these inferences. Three conditions were evaluated: (1) Auditory-Only, (2) Orthographic-Only, and (3) Combined Auditory/Orthographic. It was hypothesized that right hemisphere damaged persons would perform most successfully when the materials (narrative paragraphs) were presented using the combined condition. Both groups performed significantly better in the combined Auditory/Orthographic condition. There were no significant differences in the performances of the RHD group as compared to the normal controls. This suggested that the RHD group did not exhibit an inference impairment on this type of linguistic task.
本研究有两个目的。第一个目的是比较9名右脑损伤（RHD）成年人与18名匹配的正常对照组的间接推理能力。第二个目的是确定向RHD个体呈现信息以形成这些推理的最佳条件。评估了三种条件：（1）仅听觉，（2）仅正字法，以及（3）听觉/正字法结合。研究假设，当使用听觉/正字法结合的条件呈现材料（叙述段落）时，右脑损伤者的表现最为成功。两组在听觉/正字法结合的条件下表现都明显更好。与正常对照组相比，RHD组的表现没有显著差异。这表明RHD组在这类语言任务中没有表现出推理障碍。
