Ch 2 · The oddball effect and the science of surprise
artiteacher The Oddball Effect
When a brand-new wonder hits your brain— (Time slows down again!) Yeah, the oddball stretches the view— (Making a second feel like two!)

artiteacher In Yale's 2023 study, the asymmetrical post-oddball lingering effect dilates time for objects immediately after a surprise, but

artiteacher A diagram shows how a surprise oddball stretches a timeline compared to routine events.
Fun Fact
Pupil time dilation: When you spot a surprising object, your brain triggers pupil dilation to gather more visual information, which directly correlates with stretched time perception.
Glossary
oddball effect (noun)
A psychological phenomenon where an unexpected stimulus in a repetitive sequence is perceived as lasting longer. In 2004, scientist Peter Tse demonstrated this using repeated shoe images followed by a single flower.
