This program is a virtual EEG (electroencephalogram) lab. In the EEG literature there are lots of experiments that compare objects, such as comparing faces to butterflys, birds to dogs, etc. Their goal is to determine how the brain processes different kinds of objects.
You can use this program to do something similar. We have collected the brain responses from a large number of subjects while they viewed the images below. You can use this program to group the pictures into different categories, and run your own experiment. In fact, there are 2.3 x 10 ^ 216 (a really big number!) different ways to group these stimuli into the six categories, and so it's likely that your own virtual experiment has never been run and you might discover something that we didn't know about how the brain processes visual images.To run your own experiment, first scan through the pictures to get an idea of what you'd like to compare. Note that we tried to include a wide range of stimuli, both positively and negatively arousing, and included a lot of people pictures. None of them are revealing but some of them are provocative. This program should be used with adult supervision for users under the age of 18.
