This chapter, which considers the top-down modulation of the right-ear advantage in dichotic listening, first introduces Doreen Kimura’s view on the mechanisms invoked by dichotic listening. It then reviews more recent evidence on some of the central topics of dichotic listening, and addresses the possible role of attentional processes in dichotic listening. The chapter suggests that the right temporoparietal junction may serve an important function in dichotic listening in that it may be triggered by the left-ear input to disengage attention from the dominant right-ear input, and also shows that the posterior superior temporal gyrus is important in the processing of dichotic stimuli. Moreover, it reveals that left-ear extinction in dichotic listening cannot be reduced to disturbances of space representation.
