Welcome

We want to understand how humans perceive age.
You can help by taking a short test (about 3 minutes).

You will be presented with a series of photographs for which you will either be asked:
  1.  To estimate the persons age
  2.  To provide feedback on a suggested age

There is no time limit - take as long as you need, but do not go away and attempt to research the subject of the picture. The experiment is not intended to test your ability, and the true ages are not relevant to this research. We just want to know how old you think they look!

Following the collection of sufficient data, the results from this research will be published. Details will be provided on this page. For other queries contact us.
