In accordance with TalkBank rules, any use of data from this corpus must be accompanied by at least one corpus reference.
This corpus is treatment probe and assessment data for an NIH-funded project (R01DC019325-01A1) that seeks to evaluate two novel computer-based anomia treatments designed to integrate complementary learning principles via adaptive modeling. Picture-based naming treatments for anomia are widely used in aphasia rehabilitation, but current treatment approaches do not address the long-term retention of naming abilities and do not focus on using these naming abilities in daily life. The current research aims to evaluate novel anomia treatment approaches to improve long-term retention and generalization to everyday life and develop new aphasia-specific learning and word production models to improve aphasia rehabilitation. This clinical trial is divided into two sub-studies. The first study (https://clinicaltrials.gov/study/NCT05653440), titled "Balancing Effortful and Errorless Learning in Naming Treatment for Aphasia", evaluates a picture naming retrieval practice condition using adaptive naming deadlines to non-adaptive treatment conditions using errorless and effortful learning.
The second study (https://clinicaltrials.gov/study/NCT05653466) , titled "Adaptive Trial Scheduling in Naming Treatment for Aphasia" evaluates a picture naming retrieval practice condition that combines massed and distributed practice via adaptive trial scheduling, compared to non-adaptive treatment conditions.
To evaluate stimulus generalization of trained words to connected speech, discourse probes were administered twice at 4 distinct timepoints for each treatment condition: pre-treatment, 1-week post-treatment, 3-month follow-up, and 6-month follow-up for a total of 8 times throughout each treatment condition. The discourse probes consist of 26 items – 15 complex picture scenes and 11 text-free stories. The participants are given a subset of these probes as single or multi-page picture description tasks. The probes contain untrained picture models of treated and untreated nouns from each participant’s stimuli words which evaluated the use of treated words in discourse. Participants are asked to describe what they see in detail. Time limits for discourse probe description were implemented to reduce testing burden while maintaining feasibility of completion for participants with aphasia.
Participants completed the Comprehensive Aphasia Test at baseline to characterize their language profile and language severity, and also complete the Aphasia Bank Discourse Protocol before and after treatment to evaluate far transfer of treatment effects.
Standard restrictions apply. Per our Pitt IRB protocol, we state: “Only members of the Aphasia Bank research group will have access to the audio/video recordings, which are password protected. Researchers agree not to share recordings with others, which may only be used for research and educational purposes.”
