We are conducting a perception study on human faces: I hope you can take 10 minutes of your time to do it.

REAL or SYNTHETIC?? Are you 18 years or older? Then help us understand better how humans perceive computer-generated faces!
We will ask you to guess which human faces are real and which are synthetic. The experiment is designed to be taken on a desktop or laptop computer to allow proper visualization of the images and will take no more than 10 minutes of your time.

Thanks a lot,
