The purpose of this study was to examine memory abilities of aphasic individuals in relation to site of neurological lesion. Fourteen individuals with stroke-induced aphasia (7 with anterior lesions; 7 with posterior lesions) and 14 demographically matched control subjects were given selected tests of short-term memory (STM) and long-term memory (LTM). Stroke patients were impaired relative to control subjects on tests of verbal memory, with greater impairment of LTM associated with anterior lesions and greater impairment of STM associated with posterior lesions. Verbal memory performance did not correlate highly with language ability, and did not appear to be simply a consequence of language impairment. Executive control deficits were postulated as explanatory of the LTM impairment associated with anterior lesions.
本研究的目的是检验失语症患者的记忆能力与神经损伤部位之间的关系。对14名中风所致失语症患者（7例为前部损伤；7例为后部损伤）和14名人口统计学匹配的对照受试者进行了短期记忆（STM）和长期记忆（LTM）的选定测试。在言语记忆测试中，中风患者相对于对照受试者存在损伤，其中前部损伤与LTM损伤更大相关，而后部损伤与STM损伤更大相关。言语记忆表现与语言能力的相关性不高，似乎并非仅仅是语言损伤的结果。推测执行控制缺陷可解释与前部损伤相关的LTM损伤。
