• Floating?
Illusion Confusion
A 2-D Drawing
• Whose head is whose?
• A dog that climbs walls?
• A hairy conundrum
• Heads-up!
- the top horizontal line looks longer is because we interpret the scene using linear perspective
- the vertical parallel lines seem to grow closer as they move further away
- So we interpret the top line as being further off in the distance.
- An object in the distance would need to be longer in order for it to appear the same size as a near object
- so the top "far" line is seen as being longer than the bottom "near" line, even though they are the same size.
Ponzo Illusion
Muller-Lyer Illusion
Optical illusions can be fun and interesting but they also serve as an important tool for researchers. By looking at how we perceive these illusions, we can learn more about how the brain and perceptual process work. However, experts do not always agree on exactly what causes optical illusions, as is the case with the Müller-Lyer illusion.
