The effects of increased information redundancy on word retrieval in aphasic patients was investigated in this study. Protocols involved combining five types of cues commonly utilized in aphasia management into eight pairs, each of which could be presented simultaneously. The resulting cue combinations were presented to 16 anterior lesion aphasic subjects who manifested mild to severe word-finding difficulty. All of the combinations were effective in facilitating picture-naming performance, with the severe group demonstrating the most dramatic improvement when simultaneous prompts were utilized. A cueing hierarchy incorporating increased stimulus redundancy is supported.
本研究调查了信息冗余增加对失语症患者词汇检索的影响。实验方案包括将失语症治疗中常用的五种线索组合成八对，每对线索可同时呈现。将由此产生的线索组合呈现给16名有前部病变的失语症受试者，这些受试者表现出轻度至重度的找词困难。所有组合都能有效促进图片命名表现，其中重度组在使用同步提示时改善最为显著。支持包含增加刺激冗余的线索分级体系。
