Can you tell when someone is looking at the same photo you are? This experiment requires two people and takes less than five minutes to complete.

How it works

One of you registers a group name, then you both log in at a prearranged time. In each of 12 trials you'll be randomly shown either the same picture or different ones. After 10 seconds, you'll be asked "Was your partner looking at the same picture?" In half the trials you'll do the guessing while your partner concentrates on the image, then in the second half you'll reverse roles.

Notes for teachers, group leaders and family-group participants

These experiments can be done with students as an assignment or as a research project. Students should be in separate buildings, or in in the same building in separate rooms, beyond the range of sight and hearing. Please contact us for the results of your tests, which can be made available in a detailed online report.


If you experience any problem running the experiment, kindly contact us with your group name, internet browser and most importantly the URL at which the error occurred along with a brief description of the problem.
