Pupil Size Reveals Inner Speech vs. Speaking Aloud
Recent scientific research investigates how the human body reacts differently when a person speaks out loud compared to when they engage in silent internal dialogue. Scientists utilize eye-tracking measurements to uncover physiological markers that distinguish these cognitive states. Understanding the mechanics of inner speech offers deeper insight into human thought processes, self-regulation, and mental health. These findings highlight how subtle bodily responses can reflect complex neurological activities.
