For each experiment we randomly select and invite by email a number of registered volunteers. So to be invited you have to register first. When you are invited you can sign up on-line to the experiment (the invitation will tell you how). If you don't sign up you cannot participate.
Each individual is allowed to register only once. Double registrations will be removed from the database.
Please enter your details in the compulsory fields carefully and exactly as they appear on your student ID. Once you entered them you will not be able to change them yourself (except email address). If any changes are required, please contact us.
Note that participation is voluntary - if you do not want to take part in a particular experiment, you do not have to. If you wish to withdraw your participation, you are free to do so. If you sign up to a particular experiment we expect you to attend; if you don't you cause us problems: you force us to run extra sessions and sometimes you even force us to cancel the session, in which case you also inconvenience your fellow students that do turn up to that session. Please note that we reserve the right to remove from our register (and thus stop inviting) volunteers who sign up to sessions and then fail to show up without good reason.
