Genetic and Cognitive Predictors of Aphasia Treatment Response

The proposed study will administer Cued Picture-Naming Treatment (CPNT) four days per week for four weeks (i.e. 16 sessions). During therapy, participants will attempt to name eight consecutive presentations of the same black and white picture, for each of the 20 pictures, with cueing from the administrator. Trials will include (1) independent naming, (2) orthographic cueing (i.e. the written word beneath the picture.), (3) repeating, (4) naming after a short delay (i.e. approximately three seconds), (5)semantic cueing (i.e. three cues providing semantic information about the target will be spoken to the participant by the clinician), (6) phonological cueing (i.e. the first sound and letter will be spoken by the clinician), (7) repeating, and (8) naming after a short delay. The administrator will provide the correct response for each incorrect participant response and will ask the participant to repeat it.
