Interaction & Reaction
What do we often encounter when we talk with guilty people versus non-guilty people we’re investigating. Guilty people often get defensive, where an innocent person is going to go on the offensive. The individual will become “stronger” in their response “I didn’t do it, I didn’t do it!” Where a guilty person starts to try and explain their way. A liar is uncomfortable facing his questioner/accuser and may turn his head or body away. They may be sitting with their legs crossed and then shift their entire body away from you. This is because they are uncomfortable facing the individual. A liar might also unconsciously place objects such as (books, coffee cup, etc.) between themselves and you. This creates a sense of a barrier between you as the interviewer and themselves.
Change of conversation
If you believe someone is lying, then change the subject of the conversation quickly. A liar follows along willingly and becomes more relaxed. The guilty person wants the subject changed; an innocent person may be confused by the sudden change in topics and will want to go back to the previous subject.
Linguisticsociety.org defines Neurolinguistics as “the study of how language is represented in the brain: that is, how and where our brains store our knowledge of the language (or languages) that we speak, understand, read and write, what happens in our brains as we acquire that knowledge, and what happens as we use it in our everyday lives.”
If the person’s eyes are up and to the right, we’re visually remembering images. If they are going to the side-right, we are remembering sounds. If the person’s eyes are going down and to the right, we’re remembering internal dialog.
