Speech lateralisation and phonological skill.
A phoneme segmentation task requiring Ss to produce deliberate spoonerisms was performed by 78 undergraduates, along with a dichotic monitoring task and tests of hand preference and hand skill. The hypothesis that those performing badly on the speech task would include a higher proportion of individuals with left ear advantage on the dichotic task was supported. The distribution of cases was consistent with other findings for relationships between cerebral speech lateralisation and side of ear advantage and also consistent with predictions of the right shift theory of handedness and cerebral speech (Annett, 1972, 1985).
