Abstract

Purpose: Picture naming assessments are one of the most common methods of examining word retrieval in aphasia. However, currently, it is unclear whether these assessments are able to accurately predict word retrieval in “real-life” communication. This paper aims to explore the evidence in the current literature regarding the relationship between picture naming and word retrieval in connected speech in people with aphasia. 

Method: Literature was reviewed that examined the correlation between picture naming and word retrieval in connected speech. The literature search was limited to articles that were English language, participants with aphasia, and that were not therapy studies. 

Result: The existing studies showed mixed findings. However, comparison of study outcomes was complicated by inconsistency in the research methods used, including in word retrieval measures and connected speech elicitation. 

Conclusion: While there is some evidence of a relationship between picture naming and word retrieval in connected speech, correlation outcomes were mixed with possible influences from participant characteristics, assessment method and speech sample type. We therefore suggest that clinical decision-making would benefit from supplementing picture naming tests with an analysis of word retrieval in connected speech. Further research is required with a focus on natural conversation and the development of standard testing procedures for connected speech.
