This section explains how to use LIONESS to run an interactive experimental session on Amazon Mechanical Turk (MTurk). Please note that you first need to create an MTurk Requester account. The process is quite straightforward but bear in mind that you must have a US address.

You now need to add funds to your account. Amazon will take your credit card and process it as you normally do when purchasing a book from them. To add funds to your account, select Account Settings (top-right corner of the screen above) and then Prepay for Mechanical Turk HITs.
Please keep in mind that Amazon will charge you a 10% fee (or $0.005 for transactions under $0.05) every time you make a payment to other people.
