A groundbreaking new study has captured international attention, suggesting that what humans perceive in the present moment is actually a snapshot from up to 15 seconds in the past. This fascinating finding challenges longstanding assumptions about how the brain processes visual information and could have far-reaching implications for cognitive science, education, and even the design of safety protocols in everyday life (Times of India).

The research, conducted by a team of neuroscientists and recently highlighted in the international press, explores the mechanics of the brain’s ‘visual buffer’—a mental process where the brain accumulates and merges visual stimuli over a period of time. According to the study, rather than updating our internal picture of the world from instant to instant, our brains synthesize the last several seconds of visual inputs to create a stable, coherent scene. As a result, our conscious perception lags behind real-time events by approximately 15 seconds.

Scientists have uncovered a powerful illusion in how we remember the timing of repeated events, showing that the more often something is repeated, the further in the past its first occurrence feels—even when that’s not actually the case. This phenomenon, documented in a recent study published in Psychological Science, may have far-reaching repercussions for how we piece together our personal memories, judge news events, and even recall everyday experiences—significant insights for a society like Thailand’s, where repetition in news, advertising, and education is common.
