The problem is when I have to give the answer. First, the experiment is not accepting immediately the answer. Even though, when it accepts it moves to that part were localization is ask and after that moves to a different pair of images (what is good). It's supposed when the participant gives an answer to something that is written (script) to happen. Secondly, independently of what the participant answer is ("1" or "0") the experiment go to those parts were the quadrant localization is asked.</span></p>
