What if everything you thought you knew about emotions was only half the story?
In this opening episode of the Nonverbal ACEs Masters Series, Dr. David Matsumoto — one of the world’s foremost authorities on emotion science, cross-cultural psychology, and the universality of facial expressions — challenges practitioners to go deeper than conventional training ever goes.
Drawing on decades of research spanning evolutionary biology, FACS methodology, and cross-cultural studies, Dr. Matsumoto unpacks:
- Why facial expressions are biological tools, not cultural inventions — and what that means for how you read clients
- The “open system” model of emotion: how triggers are learned, but responses are hardwired
- Display Rules vs. Instrumental Behaviour — the two distinct layers of cultural influence that mask what clients truly feel
- Why “Universalist” vs. “Constructivist” is a false debate — and what actually bridges them in clinical practice
- What micro-expressions and subtle expressions reveal that macro-behaviour conceals
Whether you’re a therapist, psychologist, or coach, this episode reframes emotion not as a psychological concept — but as a biological system you can learn to read with precision.
