Backward Masking (BM) functions have been shown to relate to age, lead toxicity, and in children with language disorders. These functions may be indicative of auditory processing deficits. This study investigated if Evoked Potentials (EP) could be utilized to obtain BM functions. The design of this study allowed observation of the early, middle, and late auditory evoked potentials. This process allowed us to observe the differential electrophysiological responses of evoked potentials during the BM effect. This study was randomized using four different stimulus conditions. With a long inter-stimulus interval and high sample rate simultaneous early, middle, and late potentials were obtained. The stimuli were a pure-tone alone, (1) 1000 Hz, (2) a masking noise alone, (3) the pure-tone followed by the masking noise, and (4) a control condition with no auditory stimulus. This approach, using a randomization allowed any adaptation or habituation to the stimuli to be equally distributed within each condition. Us... |
