Left cradling and left ear advantage for emotional speech: Listen to the other side too

Abstract

In a recent issue of this journal, Turnbull and Bryson (2001) examined a possible relation between left ear (right hemisphere) advantage for perception of emotional speech and the universal preference of mothers to cradle infants on the left side, referring to a hypothesis that we had previously suggested (Sieratzki & Woll, 1996). Although they concluded that their data do not support our theory, reanalysis does suggest a connection between the hemispheric asymmetry for speech prosody and the leftward cradling bias.
