Screen participants by starting your experiment with a control task. You can configure the task to expect certain responses, and if those aren't met, the participant's session will stop and their data will be disqualified. This is currently only implemented for Category Induction tasks.
Configure a qualifying task
The current qualification criteria for a task are shown in its qualification page. You can make new criteria, by performing the task yourself and choosing the "expected" responses. When you view the results of your participation for the intended task, you will see a button to "Use these data as qualification target". Press this button to replace the current criteria with the ones you just selected. To cancel the qualification, simply click the button "remove qualification".
