ARC Analysis 

Action, Reason, Concern

 Dr. Garrison developed the ARC Analysis system as a way to identify and think through concerning nonverbal behaviors.  The system takes you through observing an action (i.e., behavior), being able to identify the purpose of that action, and prompting you regarding the best course of action to take.  It will guide you to identify when to investigate a behavior, when to note hidden suspicious behaviors, or when behaviors may indicate that your safety or someone else’s safety needs to be immediately considered.

 Action:  The nonverbal behavior/communication you observe.

  • Actions matter when they occur after a baseline (or starting point) has been established.  In other words, it means far less if someone has their lips pursed during an entire interview or they are constantly touching their face throughout an interview than if the behavior spontaneously occurs during the interview process.

 Reason:  The purpose that an individual engages in that unconscious action.  The person is unaware of what they are doing.

  • What is the underlying meaning and motivation for this behavior?  What is this behavior attempting to calm or pacify (e.g., stress, worry, or anxiety)?

 Concern:  The types and degree of concerns associated with the observed behaviors. Each behavior is associated with a prompt.  It is called a prompt because the behavior should prompt you to explore more or pay added attention to other behaviors. 

  •  Minimal:  This behavior does not indicate any problems or the meaning is too inconsistent to be categorized.
  • Examine Prompt:  The observed behavior should prompt you that something is worth exploring.  The individual is trying to soothe themselves.  It could be lying, deceit, nervousness, discomfort, or strong emotion. 
  • Suspicion Prompt: These behaviors are not always an indication of lying or deceit, but are more often associated with it.  These behaviors should be strongly noted. 
  • Safety Prompt:  The observed behavior may suggest that the safety of yourself or others may be at a high risk due to behaviors that suggest anger, preparing for action, or possibly preparing to run.  These behaviors should be observed with appropriate caution.
