This experiment was set up by Julian Todd (programming in Java) and Rebecca Lawson (a cognitive psychologist at the University of Liverpool, England).
The experiment is designed to test the limits of your ability to learn ..... and it is a real challenge! Go for it and if you think its tough - it is! We want to see if you can get to the end and learn to categorise the leaves.
This is a NEW experiment (set up on 28 November 2000) ***BUT*** if you have already done another, similar leaf experiment for us, please click on "YES" when asked if you have "Done the experiment before".
We'd also like to hear your comments - there's a comment box at the end. Rebecca's email address is rlawson@liv.ac.uk
