Summary

This randomized controlled comparative effectiveness study examines manipulation of a key component of an established and efficacious treatment for naming impairments in aphasia, along with cognitive and brain correlates of treatment success. Study participants will be randomly assigned to one of two treatment conditions comparing two different versions of Semantic Feature Analysis treatment. Their performance on standardized and study-specific measures will be used to determine which version of the treatment provides superior outcomes, and measures of automatic language processing and functional brain imaging will also be used to identify the underlying neurocognitive mechanisms associated with positive treatment response.

Interventions

BEHAVIORAL

Semantic Feature Analysis Treatment

On each treatment trial, the clinician will show the participant with aphasia a pictured object and ask them to name it. The clinician will then guide the participant in verbally generating semantic features for the target, using a chart that specifies five kinds of features: group, use/action, properties, location, and personal associations. When the participant cannot generate a given feature, cueing or other assistance will be provided. After feature generation, the clinician will ask the participant to name the picture again and provide cueing if needed. The clinician will then review the generated features and ask the participant to name the item once more, with cueing if needed. Finally, the clinician will ask the participant to say a sentence containing the target word and provide cueing if needed. Treatment will then proceed to the next item. Participants will receive approximately 20 hours of treatment on each of three 10-item lists, for a total of 60 hours of treatment.
