I have a set of tasks that include a randomised set of sentence-completion tasks. Each task is coded as a survey question and response.
One of the data variables that I need to collect is the time from when of the survey question (text of incomplete sentence) is displayed to when the subject commences entering their response (the completion of the sentence).
I have changed the task from initially being of type survey (which only collected a small fixed set of data) to a block-based experiment with survey pages as trials. This allows me to customise the data collected. However I cant' work out how to calculate this response time.
Any suggestions??

You'll want to use <openended> elements for this, not a <surveypage>/<textbox> combination.

You can do this by logging the <openended>'s firstcharlatency property to the data file.
Hope this helps.
