Hey there, thanks in advance for helping me on this. How, in LimeSurvey do I create a survey in which I can Display two Images of equal size on the Screen and the subject has two Options on the Keyboard that he/she can press coding for each of the Images displayed. If he/she presses one, the tast will continue to the next Images. Simultaneously, I would like to measure the reaction times. How can this be realized? Thank you so much. Cheers
