Abstract:
A method for training a subject to discriminate between acoustic events that are common in spoken language by using sequences of upward and downward going frequency sweeps of frequency, and duration, and separated by an inter stimulus interval (ISI), the frequency sweeps presented to the subject for order identification, the method comprising:a) presenting a sequence having a plurality of upward and downward going frequency sweeps to the subject for order identification; b) providing buttons associated with the upward and downward going frequency sweeps to allow the subject to signal order identification for the presented sequence; c) recording whether the subject's signaled identification corresponds to the presented sequence; d) repeating steps a)-c); e) after a first predetermined number of correct identifications, reducing the ISI and repeating said steps a)-d); f) after a second predetermined number of correct identifications, reducing the duration and repeating said steps a)-d); and e) after a third predetermined number of correct identifications, increasing the number of frequency sweeps presented in a sequence and repeating said steps a)-d).
