A method for adaptively training a human subject to process, and to distinguish between, similar acoustic events that are common in spoken language is provided. The method utilizes sequences of up/down frequency sweeps, of varying frequency and duration, and having varying inter stimulus intervals (ISI) between the frequency sweeps. A sequence is presented to the subject for order identification. The subject must listen to the up/down order of a sequence, and signal identification of the up/down order according to what s/he heard. Signal identification is provided utilizing a computer display, a mouse, and graphical buttons corresponding to the up/down frequency sweeps. Correct order identification causes the process to adaptively reduce the ISI separating the frequency sweeps, to reduce the duration of the frequency sweeps, to alter the frequency of the frequency sweeps, and to increase the number of frequency sweeps within a sequence.
