space time bridge

“Space-Time Bridging” is a perceptual exercise that shifts attention from close, internal experience to more distant surroundings, linking changes in perceived space with changes in how we experience time. 1

• Fine versus broad time perception: Attention to nearby objects or bodily sensations is associated with finer time-slicing; looking farther away is associated with taking broader time “bins.” 2
• Stages and goal reflection: The exercise moves through stations—from internal sensations, to the body or hand, to a nearby location, the horizon, and a broad view—before returning inward. Huberman connects moving among these distances and timeframes with balancing immediate milestones and longer-term goals. 3 4 5
• Flexible attention: Practicing these deliberate shifts exercises the ability to move between internal and external attention. Huberman describes this flexibility as useful for adapting attention in daily life and for task-switching; he also says it can change cognitive and emotional experience. 6 7 8
