Breakes/pauses within a sequence
I created an experiment in which I display some images and geometrical form. The subject's task is to click on a square when it appears.
So basically my variables are :
-pic number (3 conditions)
-Time between the apparition of the picture and the apparition of the square ( 3 conditions)
-x,y pos of my square (4 conditions)
So I have 3*3*4 condition = 48 conditions
I'd like to add another variable which is the square color (maybe 4 conditions) but it will take too much time for my subject if I want their attention to be maintain..
So I'd like to add some breaks in my sequence.
How can I do that ?
