“…According to Inbau et al [1], "as much as 70% of a message communicated between persons occurs at the non-verbal level". Vrij and Granhag [22] list the non-verbal cues to deception found in published police interrogation manuals [1,[23][24][25][26][27]. These include problem with eye contact, touching the nose, restless foot and leg movement, avoiding eye contact/direct gaze, frequent posture changes, grooming gestures, placing hands over mouth/eyes, rubbing the eyes, covering/rubbing the ears, restless behaviour, tapping of feet, fidgeting, excessive swallowing, shuffling the feet, picking lint from clothes, high frequency of blinking, moving the chair, abrupt and jerky behaviour, problem with fine motor coordination, cold and clammy hands, covering mouth with hands, as well as failure to maintain eye contact Many of these cues were found in our subjects` non-verbal behaviour, whereby all of the subjects them were telling the truth when being recorded.…”
