Multiple Responses Overview.
There are a number of ways you can collect multiple responses
instead of the default binary response scheme DMDX uses. You can use multiple items if you're looking for an exact number of responses and use the
<ContinueClockOn> keyword instead of * or
<ClockOn> to make sure you don't loose responses made between items.
<ContinueClockOn>'s
real strength is to update the display as a response is needed to be gathered
but it doesn't have to be used with a changing display.
If you have an indeterminate number of responses to be gathered in a known time interval then you'll want to use the
<ZillionResponses> parameter.
If you want to gather one response of many for a
rating task then the
<ZillionOneResponse>
modifier of <zil> is what you'll want -- although you can do the same sort of
thing with a
<MultiwayBranching> and
binding multiple keys as valid responses
with a normal <azk> file.
If you need to gather an indeterminate number of responses then the
<ZillionTypedResponses> parameter
modifier is probably the best route and to nominate a key to terminate
responses. While <ztr> is designed for typed responses terminated with an enter key there's no reason it has to be used that way
(and for typed responses these days
<prose> is a superior solution that
even handles right to left fonts).
