In a series of reaction-time experiments two groups of minimal pairs of English words were presented monaurally to the right and left ears of left-handed subjects. The minimal pairs were /bit/ : bet/ and /splei : sprei/ recorded in natural speech. The group of left-handed subjects did not show any evidence of an ear-advantage on either of the two groups, indicating that the lateralization of speech perception processes could not be demonstrated using monaural stimulation. The performance of left-handers continues to give equivocal results on tests of speech lateralization processes.
