  • a) separating the at least two differing sound stimuli to provide an interstimulus interval of at least 100 milliseconds;

    b) prolonging the consonant sound in each of the stimuli by a factor of at least thirty percent;

    c) repeating the at least two differing stimuli in random order until the temporally impaired individual is able to distinguish the order of each stimulus;

    d) decreasing the interstimulus interval by at least a one percent factor;

    e) repeating step c) with a decreased interstimulus interval until the temporally impaired individual is able to distinguish the order of each stimulus; and

    ,f) repeating steps c) through e).
