This study used the Peabody Individual Achievement Test (PIAT) to assess reading and spelling skills in a normal control group (n = 100) and in patients having cerebral damage in the left hemisphere (LH; n = 86) or right hemisphere (RH; n = 76). Relative to the normals, both brain-damaged groups were impaired on PIAT Reading Comprehension and Spelling. Only the LH group was impaired on PIAT Reading Recognition. PIAT performances were strongly related to extent of brain damage within the left hemisphere, but not within the right. Similarly, whereas reading and spelling deficits were associated with temporal- and occipital-lobe involvement in the LH group, presence or absence of specific lobe involvement was unrelated to PIAT performance in the RH group. Relationships also were assessed between PIAT performances and demographic variables and the Average Impairment Rating from the Halstead-Reitan Battery.
本研究使用皮博迪个体成就测验（PIAT）来评估一个正常对照组（n = 100）以及左半球（LH；n = 86）或右半球（RH；n = 76）发生脑损伤的患者的阅读和拼写能力。相对于正常组，两个脑损伤组在PIAT阅读理解和拼写方面均受损。只有LH组在PIAT阅读识别方面受损。PIAT成绩与左半球内的脑损伤程度密切相关，但与右半球内的脑损伤程度无关。同样，虽然LH组的阅读和拼写缺陷与颞叶和枕叶受累有关，但特定脑叶是否受累与RH组的PIAT成绩无关。研究还评估了PIAT成绩与人口统计学变量以及霍尔斯特德 - 赖坦成套测验的平均损伤评分之间的关系。
