Hemispheric asymmetry and deception detection

Previous research has indicated a possible right hemisphere advantage in deception detection including a possible left ear advantage in decoding deceptive statements. In this study, 32 undergraduate students listened to 112 true and false statements presented unilaterally to both the left and right ears. The participants responded using their left or right hand, indicating whether the statements they heard were true or false. It was found that there was a significant (p <.004) advantage for the left ear in detecting whether a statement was true or false. These findings replicate and extend previous research indicating a left ear/right hemisphere advantage in deception detection.
