A dichotic rhythm task: advantage for the left-handed.
Right- and left-handed subjects responded to a task which required identification of signal events embedded in four-beat dichotic rhythm patterns. Left-handed subjects reported a significantly greater number of signals from both ears than did right-handed subjects. The results suggested that left-handed subjects may be better able to analyze simultaneous stimuli and integrate differential information from them into a coherent response structure. The data further support a bi-dominant theory of left-handedness.
