Reaction Time

Apr 11, 2016 at 2:57 PM
Hi there,

I'm hoping someone can help me.

I have programmed a slideshow task whereby pictures appear with a text question underneath. I have the test response as specific keys (Y for yes and N for no). I was wondering if there is anyway to calculate reaction time using this software? I.e. the amount of time it takes the participant to hit Y or N from when the picture is first presented on screen? I can't seem to find an option to export this information when analysing.

Many thanks,
Alex

Hi Alex,
you are right, there is no time information on the key responses in the statistics module. It would be relatively easy to implement this using the sources and I put this on the wishlist. In the meantime it might be a workaround that you look at the database module at the trial events table. There is a column called event time with the time until this response (e.g. key press) happened counted from the beginning of the trial. You can export this table also.
Regards,
Adrian
