The main screen subjects will interact with during an experiment is the Play tab on the subject software. This is where subjects select actions, view total balance, and stay aware of other information.

The experimenter can control some additional aspects of what the subject sees while playing the game, such as a history of past moves, various reminders, and even additional instructions. Client display parameters are accessed at the bottom of the Session parameters tab.

  • Have player validate new opponent W/L profile: Each Subject must validate his opponent's win/lose information of new opponents before a match begins. A dialog will be shown requesting the subject input his opponent's number of wins and loses. Enabled only when Show new opponent message and Show opponent's win/loss profile options are in use. This option helps make explicit an opponent's past performance.

  • Help tab url: This option provides a method to display additional information to the subjects in a Help tab on the subject display. If a valid url is given, the subject screen will display an addional tab that contains the contents of the web page targetted by this url. The Experimenter is responsible for creating and hosting this additional content.
