To keep the participant interested, we want to give him a little extra task, like counting random red dots. So here's what we came up with: On random images, a red dot should appear in a random position on the screen. The task would be to count the number of red dots being shown during the presentation. So here are my questions: How can I show a red dot, in a random position? How can I count, how many times the red dot appeared, so I can give the participant a feedback wether he was right or wrong? (custom value++)? thanks a lot!! best regards, Manu
