Two experiments are described in which subjects were requested to recall dichotic digit pairs. The results of both experiments showed a significant right ear advantage for the digits. In the EEG a strongly lateralized sustained positive wave was present in the pre‐response period. The asymmetry of this component appeared to be both task dependent, and related to individual differences in ear asymmetry. It is suggested that the sustained wave is a manifestation of differential mobilization of resources of the two hemispheres that compete for limited capacity in a particular stage of the task.
