Systems and methods for user-dependent conditioning of stimuli in tests using a method of continuous adjustment

An auditory testing device comprising:

• at least one processor;
• and
• at least one memory storing instructions, which when executed cause the at least one processor to:
• generate a user stimulus signal according to a first adaptive parameter and a second adaptive parameter;
• modify the first adaptive parameter in order to generate a plurality of successive variations in the user stimulus signal, such that the plurality of successive variations in the user stimulus signal are generated over one or more given ranges of values of the second adaptive parameter;
• receive, in response to modifying the first adaptive parameter, a plurality of user responses from a given user, each user response indicating that a corresponding one of the plurality of successive variations in the user stimulus signal has occurred;
• and
• based at least in part on an expected user response curve for the given user and a calculated time interval between successive ones of the plurality of user responses received from the given user, adjust an instantaneous rate of change for modifying the first adaptive parameter such that the user responses are steered toward a neutral state around the expected user response curve.
