Hello
I am using <radiobuttons> within <surveypage> to collect responses from our participants. I wonder if there is a way to record the time when radiobutton is pressed, and output such timestamps to the *.iqdat files? The idea is to estimate how much time respondents spent considering each item (<radiobuttons>), to screen out unusually quick respondents.
Currently, I have multiple <surveypage> grouped under <survey>. When things are organized that way, the 'latency' field of all <radiobuttons> that are embedded in the <survey> get the same value, which I believe is the time the respondent spent on that survey, from when the survey was displayed on screen until the respondent presses the 'Next' button.
I've tried to group the <surveypages> under <block>: Indeed, the *.iqdat files are generated in "long" format -- with one line per <radiobuttons> -- but the 'latency' values for all <radiobuttons> grouped in the <block> still get the same value.
Any help will be greatly appreciated. Thank you very much in advance!
