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.
