TL;DR

Right ear perceptual advantages were found on these dichotic monitoring tasks, lending support to the contention that short-term auditory memory and verbal report are not required for the dichotic ear effect.

Abstract

This study examined auditory selective attention in primary generalized and complex-partial (temporal lobe) epileptics using binaural and dichotic versions of the Continuous Performance Test. The patient groups did not differ from normal controls when only one channel was presented or when divided attention (simultaneously monitoring two channels) was required. However, generalized epileptics had significantly depressed hit rates when directed attention (responding to critical stimuli in only one channel) was required. These results suggest a contribution of brain stem "arousal" mechanisms to stimulus set attention. In addition, right ear perceptual advantages were found on these dichotic monitoring tasks, lending support to the contention that short-term auditory memory and verbal report are not required for the dichotic ear effect.
