Semantic cueing effects on word retrieval in aphasic patients with lexical retrieval deficit.

We examined lexical access in word production, focusing on lexical retrieval deficit in aphasic patients. These patients were asked to name one picture at a time and we investigated how semantic cueing affected their ability to retrieve the word. When the subjects experienced a retrieval failure, they were presented with one type of cue, and then they tried to name the target picture again. Four types of cues were used: phonological, semantic related, semantic category member, and baseline cue. Both phonological and semantically related cues improved performance. In contrast, category member cues had no effects on releasing the retrieval block. These results can be explained by an interactive activation model in word production (Dell & O'Seaghdha, 1991).
