What Does a Cue Do? Comparing Phonological and Semantic Cues for Picture Naming in Aphasia
Abstract
Impaired naming is one of the most common symptoms in aphasia, often treated with cued picture naming paradigms. It has been argued that semantic cues facilitate the reliable categorization of the picture, and phonological cues facilitate the retrieval of target phonology. To test these hypotheses, we compared the effectiveness of phonological and semantic cues in picture naming for a group of individuals with aphasia. To establish the locus of effective cueing, we also tested whether cue type interacted with lexical and image properties of the targets. Individuals with aphasia (n = 10) were tested with a within-subject design. They named a large set of items (n = 175) 4 times. Each presentation of the items was accompanied by a different cueing condition (phonological, semantic, nonassociated word and tone). Item level variables for the targets (i.e., phoneme length, frequency, imageability, name agreement, and visual complexity) were used to test the interaction of cue type and item variables. Naming accuracy data were analyzed using generalized linear mixed effects models. Phonological cues were more effective than semantic cues, improving accuracy across individuals. However, phonological cues did not interact with phonolog...Continue Reading

Aphasia
Aphasia affects the ability to process language, including formulation and comprehension of language and speech, as well as the ability to read or write. Here is the latest research on aphasia.
