Abstract

We investigated the influence of stimulus characteristics and tasks (count and simple reaction tasks) on auditory P50. Ten normal volunteers served as subjects. EEGs and auditory evoked potentials were obtained from Fz, Cz, Pz, C3, C4, T3 and T4 referred to linked earlobes (LE) and balanced non-cephalic (BN) electrodes. In the recordings using a BN reference there were significant negative correlations between the reaction times and P50 peak latencies at Fz, Cz, Pz, C3 and C4. In the LE reference recordings there were negative correlations but these did not reach statistical significance. The results are discussed with reference to the activation of the LE reference and the neural sources of P50. The findings suggest the possibility that reaction times are determined at the very early stage of auditory information processing.

Auditory Perception

Auditory perception is the ability to receive and interpret information attained by the ears. Here is the latest research on factors and underlying mechanisms that influence auditory perception.
