Hemispheric asymmetry for the auditory recognition of true and false statements.
A group of right-handed adult subjects (24 males and 24 females) were asked to judge phrases as to their truthfulness of falsehood, by listening to them via earphones either with the right or with the left ear. These phrases, which had been previously recorded by two non-actors (1 male and 1 female) and two actors (1 male and 1 female), were either true or false. The number of correct judgements made by the subjects was significantly higher than the number of wrong judgements. The subjects correctly recognised significantly more true phrases than false ones. Moreover, they better recognised true phrases pronounced by the actors and false phrases pronounced by the non-actors. True phrases pronounced by male speakers and false phrases pronounced by female speakers were better recognised. A left-ear advantage was found in the recognition of true statements.
