Experiments

There are two online experiments that will each take about 10 minutes to complete. You may choose one or both experiments.


Change Blindness: Search for objects within livingroom scenes.
This experiment is very fun and particularly challenging. It is kind of like finding Waldo in the "Where is Waldo?" pictures.
Time : approximately 10 minutes
Note : This experiment can take more time than 10 minutes, but that all depends on how fast you can find the objects!

Image Cropping: View a number of artificial and natural scenes.
Time : approximately 5 minutes
Note : See feedback at the end of the experiment about how you performed compared to other participants!
