Subliminal Stimuli

Just a set of two examples of subliminal stimuli. Perhaps a little too slow to classify as 'subliminal' stimuli but should be useful for a couple of tests. Publishing results from 5 test subjects soon so stay posted! (Both images created by Henstargames, available for use anywhere royalty free.)

^ 'Blink' response.

^ 'Yawn' response.

Test image two is likely going to be more successful in my opinion, leave your guesses in the comment section below!
