Dr. Luke Jones: Psychophysics, Internal Clocks & Passage of Time

In this episode, Dr. Luke Jones takes us from his early Ganzfeld sensory-deprivation experiments to today’s cutting-edge investigations in psychophysics and time perception. He demystifies core concepts—like Stevens’ power law and internal-clock (pacemaker–accumulator) models—while teasing apart duration judgments versus the felt passage of time. Along the way, Lucas introduces Zakay’s temporal-uncertainty framework, contrasts prospective and retrospective timing, and examines how attention, novelty, emotion, aging, and even clinical conditions (Parkinson’s, autism, ADHD) warp our temporal experience. Listeners will also discover innovative approaches—from animal reinforcement studies and VR setups to predictive-coding theories—and hear surprising insights inspired by the Christmas paradox, psychoactive substances, and lessons from musical performance and teaching.
