7. A method of altering a recipient's ability to hear with a hearing prosthesis implanted in a recipient, comprising: subjecting a recipient who has participated in a plurality of respective temporally spaced aural training tasks to a plurality of respective temporally spaced aural tests, the respective aural tests evoking hearing percepts evoked by the hearing prosthesis; influencing the recipient's commitment to performing subsequent aural training tasks based on first data relating to the aural tests; and at least partially refitting the hearing prosthesis after influencing the recipient's commitment to performing subsequent aural training tasks and after the recipient has engaged in the subsequent aural training tasks.

The method of claim 7 , wherein: the action of influencing the recipient's commitment includes presenting second data to the recipient, wherein the second data are data indicating a difference in ability to hear with the prosthesis relative to that which would be the case if different temporal spacing between respective aural training tasks had occurred relative to that which was the case with respect to the participated aural training tasks.
