Hypothesis
Can dazzle patterns distort speed perception?
Conclusion
Dazzle patterns can distort perceived speed, especially at high speeds.
Supporting Evidence
- At high contrast and fast speeds, zigzag and check patterns were perceived as moving slower than a plain pattern.
- The effect was significant, with a reduction in perceived speed of around 7%.
- Dazzle camouflage may provide protection in military contexts by distorting speed perception.
Takeaway
This study shows that certain patterns can make fast-moving objects look like they're moving slower, which could help them avoid being hit.
Methodology
Participants were shown different patterns and asked to judge which moved faster in a binary choice task.
Limitations
The study only tested a limited range of patterns and speeds.
Participant Demographics
Naïve subjects, 15 in each of two groups.
