The role of articulation in verbal short-term memory was investigated in two anarthric patients, C.M. and F.C., both showing normal comprehension for written and spoken language, above average intelligence and visuo-spatial abilities. Based on experimental results, we propose that subvocal articulation might be impaired in anarthric patients in different ways, according to the site of lesion: in 'locked-in' patients only the articulatory rehearsal processes necessary to enhance memory performances is involved, while in cortical anarthric patients the lesion affects the articulatory recoding processes involved in transferring visually presented material into an articulatory form for better retention.
在两位失语症患者C.M.和F.C.身上研究了言语清晰度在言语短期记忆中的作用,这两位患者对书面和口头语言的理解均正常,智力和视觉空间能力高于平均水平。基于实验结果,我们提出,根据病变部位不同,失语症患者的默读清晰度可能会以不同方式受损:在“闭锁综合征”患者中,仅涉及增强记忆表现所需的发音复述过程,而在皮质性失语症患者中,病变会影响将视觉呈现的材料转换为发音形式以更好保留所涉及的发音重新编码过程。
