I am designing an experiment where the participants input freeform responses (i.e., a short essay), and they are only given a specific amount of time to write (e.g., 3 minutes). I was wondering if there is a way to display a countdown timer on the screen that mirrors the duration of the TextDisplay screen that I am using to record the response, this way the participants know how much time they have left. Right now I have everything working aside from this, and it really would be the icing on the cake if I could somehow get this working (with your help of course  .
Any suggestions? and thanks in advance....

Hello,
I would recommend taking a look at the following sample that is available on our web support site (you will need to register using your serial number if you have not already):
SAMPLE: Count Down Clock
The Stimulus object contains two SlideText sub-objects – one to display the stimulus, and another to display the countdown clock. The SlideText used to display the countdown clock is blank by default; its Text property will be set in the GetResponse InLine script if necessary.
The GetResponse script loops continuously until either the subject responds (determined using the IsPending method of the Stimulus object) or the Stimulus has been displayed for the desired maximum duration. Inside the loop, the script checks to see if the Stimulus has been displayed for over 5 seconds. If so, the Text property of the second Stimulus SlideText is changed to display the countdown clock.
Please let me know if you have any questions.

IThanks! That should work, but it leaves me with another question then...can you collect freeform responses on a slide (everyway I have seen uses TextDisplay)?
Or is there a way for the slide and Text display to be displayed at the same time without causing huge problems?

Hello,
It is certainly possible to collect free form responses via the Slide object in the same manner that you can collect them with other objects. The Slide object operates in the same way as a TextDisplay or ImageDisplay object except that it can present 3 or 4 types of stimuli. That is, the properties of the object itself are identical - you can set the Duration, Allowable responses, response Time Limit, maximum number of responses, and so on, just like you can on any other response object.
To modify these properties, open the Slide object in the workspace. Then, select the name of the Slide from the drop-down menu in the toolbar. Open the Property Pages and navigate to the Duration/Input tab. You can add the Keyboard as an input mask, and then click the Advanced button to allow additional responses, add an echo client, and so on.
Please let me know if you have any further questions.
