Information provided by (Responsible Party):
Georgetown University
  Purpose
Adults who sustain brain damage due to stroke, traumatic injury or surgery may develop difficulty finding words. This study compares the effectiveness of two behavior-based programs to improve picture naming ability in these individuals.

Arms Assigned Interventions
Experimental: Errorful training condition
A type of anomia rehabilitation paradigm which allows for errors. The intervention involves providing minimal auditory cues to allow for errors in picture naming.
Procedure: Errorful training condition
Errorful training condition: Participant saw a picture and named it without any cues. If an error was produced, the cue with the least amount of information was provided (e.g. for "pumpkin", "pu"). Cues with increasing information were provided until the picture was correctly named (e.g. for "pumpkin": "pump", "pumpki", then "pumpkin"). Once the correct name was provided, the trial ended.
Experimental: Errorless training condition
A type of anomia rehabilitation paradigm in which the situation surrounding the performance of the desired task (i.e., picture naming) is controlled to prevent errors. The intervention involves providing maximal auditory cues to prevent errors in picture naming.
Procedure: Errorless training condition
Errorless learning (EL) condition: Participant saw a picture with its name, and repeated the word. The participant continued to name the picture as the auditory cues provided less and less of the word (e.g. for "banana" she would hear "banan", "bana" then "ba" and finally no cue). If an error was produced at any stage, the whole word was presented, the participant repeated it, and the trial ended.

Detailed Description:
Difficulty finding words is common in patients with aphasia subsequent to left hemisphere stroke. This study will compare two cognitive therapies for the treatment of acquired word finding difficulties. The therapies use different types of cues. All participants will receive both therapies. Participants in this study will undergo a comprehensive and detailed assessment of language and other cognitive skills. The two treatments will be compared for their efficacy.
