Timed instruction with automatic continuation

[I][edited from support email][/I]

I set up an instructions file that states "Please eat your breakfast now. You will be signaled in 15 minutes for your next set of rating."
[LIST=1][*]I would like the participant to see this screen for 15 minutes, along with a timer bar (or clock) that counts down the elapsed time for them.[*]After 15 minutes has elapsed, I would like the next item to automatically appear, without the participant needing to click on [I]Continue[/I].[/LIST]Thank you in advance for your assistance.

You can do this by making the instruction into its own self-contained questionnaire (.que file). Then, in your experiment (.exp file), add the parameter (d-900) when lisiting this questionnaire. That will cause it to be onscreen for 900 seconds and the negative sign will cause it to be timed via a countdown timer. Hint.. You can use[I] ctrl+right arrow[/I] to skip out of the item when running it as a test.

Hope that helps,
Blair
