Abstract
Two groups of right-handed young adults were tested on a series of handedness measures and on dichotic nonverbal rhythmic sequences. Cross-validated multiple regression analysis revealed that all of the cerebral-lateralization/manual-praxis measures were positively related to the degree of left-hemisphere perceptual asymmetry for nonverbal rhythms (Crawford peg, scissor, handwriting, Crawford screws, tracing, total R = .67). Seventeen of the 52 subjects manifested significant ( p < .05) left-hemisphere laterality coefficients for the dichotic stimuli. More complex rhythms elicited greater left-hemisphere perceptual preference. The results are discussed in reference to the concept of cerebral lateralization.
