Conditional formatting for instruction timing?

Group: Forum Members Posts: 5, Visits: 17	For my Inquisit task, I want to allow participants to move through instruction slides only after a pre-set number of seconds. That is, I'd like participants to only be able to press the space bar to advance to the next set of instructions after a timing delay (for example, after 8 seconds of presentation). Is there a way to format my instructions such that participants can't skip through them? Any help would be greatly appreciated! Thanks, Jess Tags conditional formatting instructions timing delay

The /wait attribute determines how long in milliseconds to wait before allowing the subject to move to the next instruction page. Thus specifying <instruct> ... / wait = 8000 ... </instruct> in your script will enforce a minimum display time of 8 seconds for any instruction page. Only then are participants able to move on to the next. If, on the other hand, you intend to display your instructions via standard <trial> elements, you can use the <trial>'s /beginresponsetime attribute to enforce the minimum <trial instructionstrial> ... / validresponse = (57) / beginresponsetime = 8000 </trial> or alternatively using /isvalidresponse <trial instructionstrial> ... / validresponse = (57) / isvalidresponse = [trial.instructionstrial.latency >= 8000] </trial>
