Assigning correct response to form base buttons
Hello, I'm trying to conduct face recognition test. I have created 4 button with form base for each trial and put the faces above them. I want participant to click the one of the button(A,B,C,D like multiple choice questions). How can assign the correct response, which button is correct. Can anyone help? Thanks.
My trials look like this. When I click on one of the button it don't record any response time or correct response
