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 a few 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 set of images, we want you to predict which image the machine got wrong. (Note: Sometimes you'll get a "hint"; maybe that will be helpful?)

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

For each of these images,
the machine was supposed to say .

Most of them it got right; but one of them it got wrong.

(Here's a hint: For the one it got wrong, it accidentally said .)

Which image do you think the machine got wrong?
To pick which one the machine got wrong, click the image.

Done! You can go ahead and submit the HIT. Thank you!
