The effect of lexical deficits on narrative disturbances in fluent aphasia
2015
Background: The label “fluent aphasia” applies to different aphasic syndromes characterised by fluent speech with difficulties in lexical retrieval and/or grammatical processing.Aims: This study aims at investigating microlinguistic and macrolinguistic skills in persons with fluent aphasia. We hypothesised that their lexical and syntactic (i.e., microlinguistic) difficulties would affect also their narrative (i.e., macrolinguistic) skills.Methods & Procedures: Growing evidence shows that traditional tests may not be sensitive enough to capture the patterns of the linguistic impairments observed in these persons. Therefore, we used a narrative task to elicit linguistic samples. Spontaneous speech was elicited through a picture description task. The narrative samples were analysed with a multilevel approach that allows clinicians to quantify their productivity levels as well as their lexical, grammatical, and narrative skills. The spontaneous speech produced by a group of 20 persons with fluent aphasia was ...
