Think like a machine!

We have a machine that can look at a picture and tell us what it is. Most of the time, it tells us the right answers. But sometimes it makes mistakes. We don't know why the machine makes the mistakes it makes; do you?

Your job in this experiment is to predict when our machine will make a mistake. On each trial, you'll see two images that will look to you like a familiar object. But, for one of them, the machine gave a different answer than it was supposed to. For each pair of images, we want you to predict which image the machine got wrong.

(NOTE: When the experiment is done, a submit button should appear. If that fails to occur, the HIT should "auto-submit" after one minute.) Start Experiment
