The dynamic changes in the latency of the components of the auditory brainstem evoked potentials (ABEP) were analyzed and correlated with the psychophysical magnitude estimates of the stimuli evoking the potentials. This study included the reanalysis of the results originally reported by Pratt and Sohmer (1977, Electroencephalogr. Clin. Neurol., 43, 802-812). this time with correction for asymptote of the latency-intensity functions. The results of reanalyzing latency-intensity power functions have yielded exponents that were very similar across components, closer to the exponent of magnitude estimates and accounting for a higher amount of variance for all of the ABEP components. This procedure may also prove useful for clinical evaluation of auditory function.
