なぜ大人の1年は、こんなにも速く終わるのか【心理学×歴史】

Before I knew it, another year was almost over. It feels like it was just yesterday that we were at the end of last year— When I was a child, a year felt so long. Summer vacation seemed to last forever. Yet now, as an adult, a year passes by incredibly quickly. Why does time seem to speed up as we get older? It's not just my imagination, nor is it due to age. It's a phenomenon that's definitely happening in your brain. Psychologists have long been searching for its true nature. Janet's Law. The Holiday Paradox. The Brain: A Camera. And we also know how to slow down the hands of that clock once again. We quietly trace the true nature of passing time, drawing on data from psychology and history. ━━━━━━━━━━━━━━━━━━ ■ Table of Contents ━━━━━━━━━━━━━━━━━━ 0:00 Opening ─ Why does a year pass so quickly for adults? 2:28 Chapter 1 ─ Janet's Law ─ A year is divided by the denominator of age. 4:49 Chapter 2 ─ The Holiday Paradox ─ Why do fun times pass in an instant? 8:01 Chapter 3 ─ The Camera Called the Brain ─ Perceived length is determined by "how many frames were recorded". 10:47 Chapter 4 ─ Reminiscence Bump ─ Why are memories of life biased towards youth? 13:20 Chapter 5 ─ How to slow down the hands of the clock again. 15:28 Epilogue ─ To make your year longer ━━━━━━━━━━━━━━━━━━ ■ About this channel ━━━━━━━━━━━━━━━━━━ "The Layers of History" is a channel that illuminates the universal mechanisms at the heart of the human mind through historical examples.

A book that also incorporates scientific verification of Janet's Law • Janet, P. (Paul Janet) — In 1877, he presented the theory that the subjective length of time is inversely proportional to age. His nephew, psychologist Pierre Janet, introduced it in his book in 1928, and it became known as "Janet's Law" (however, the scientific support is limited). • Hammond, C.

(2005) "The Age-Related Decrease in Time Awareness" — A study that investigated the relationship between aging and perceived time in 499 people aged 14 to 94.
