For a trial I want to display a sequence of 3 images over and over for 60 seconds OR until a participant responds. I know I can make a very long trial sequence in Direct RT that will allow me to show these images over and over for 60 seconds, BUT I cannot figure out how to have it stop when a certain key is pressed and take RT data at the point and not just record RT after the sequence has ended. Can I do this? And if so would it be too difficult for an
explanation?
