Hello,

I created a survey with text box elements and each text box is placed on separate survey page
I would like to know how long participant is "thinking" before  he or she start typing answer in check box, so I need to measure time between initial text box presentation on the screen and event when particpanat start typing in this text box.

I have tried to subtract survey page.elapsed time from survey page.latency, but it does not work as I expected ;(

Do you have any idea how can I measure time between text box presentation and start of typing in this text box?

Thanks for any responses Smile

To do this you should use <openended> elements instead of <surveypage>s with <textbox> elements. The <openended>'s firstcharlatency property will give you the time when the participant type the first character:

<block myblock>
/ trials = [1-2=myopenended]
</block>

<openended myopenended>
/ stimulusframes = [1=mytext]
</openended>

<text mytext>
/ items = ("Question A", "Question B")
/ position = (50%, 40%)
</text>

<data>
/ columns = [date time subject group blocknum blockcode trialnum trialcode response latency openended.myopenended.firstcharlatency]
/ separatefiles = true
</data>

It is really interesting and useful properties.
As far I know description of this properties is not present in <opened>  langage refernces in a help menu for Inquisit 4, therefore I miss it.
