Barabara,


The best and easiest option I can suggest is to use the duration parameter in your .exp file for the .que files which you would like timed. The upside is that this is very easy to do-simply use d-xxx in the parameter field of the .exp file where xxx is the number of seconds you wish to have that questionannaire timed. This will display the .que file for that amount of time before automatically ending it. You can find more information about here in the MediaLab manual: http://www.empirisoft.com/medialab/h...s.htm#duration. The downside is that this displays a countdown timer at the bottom of the MediaLab screen. You said that you did not want the time displayed to the participants, but this is the most straightforward and reliable option that is built-into MediaLab.

Good luck!
