Lab 1: The “Lie Detector” Lab (Body Language & deception)

“People lie. Bodies don’t.” Have you ever had a “gut feeling” that someone wasn’t telling the truth, but you couldn’t put your finger on why? In the world of forensic psychology, we don’t guess—we observe. While a person’s words can be carefully rehearsed, their nervous system often leaks the truth through involuntary signals. This lab pulls back the curtain on the hidden language of human deception.

The Experience

In this high-stakes interactive lab, students step into the role of a behavioral analyst. Using the pioneering science of Micro-expressions—brief, involuntary facial expressions that mirror suppressed emotions—participants will learn to decode what is happening beneath the surface.

Students will analyze real-world footage, ranging from high-profile celebrity interviews to police interrogation tapes, to identify “tells” of discomfort, cognitive load, and dishonesty. We move beyond the myths (like “looking to the left”) and focus on the scientific clusters of behavior that signal a break in baseline patterns.

Core Skills Developed

• Scientific Observation: Mastering the Paul Ekman facial coding system to identify the seven universal emotions.

• Critical Thinking: Learning to distinguish between “nervousness” and “deception” to avoid bias.

• Emotional Intelligence (EQ): Developing a heightened sense of empathy and awareness by reading subtle social cues.

• De-escalation & Communication: Understanding how to use behavioral awareness to navigate difficult conversations and build trust.
