    Timeout issue for the instruct pages

    Hello all, I've been trying unsuccessfully to have a 10 seconds timeout that would apply to each instruction page. The ultimate goal is to always have 10 seconds lapsing between any two randomly chosen blocks. I am thinking that "press the space bar to continue" would allow various participants to press the bar at different time rates, which may not be the most preferred option in the context of the experiment. Thanks greatly in advance for all your help, Respectfully, Cristian

    / font = ("Arial", -21, 700, 0, 34)

    Re: Timeout issue for the instruct pages

    Christian,

    The <instruct> element doesn't support imposing a fixed length of viewing time for each instruction page, but you could achieve this using a <trial> that presents a <text> element.

    On your trial, you can define the /trialduration command, which functions as a timeout, but if the user responds before the timeout, it waits until the timeout is hit before moving on.

    You can present a wrapped page of text using the <text> element by specifying the /size command.

    Hope this helps,
    Sean
