My dot probe task is currently set up to show a black fixation cross on the center of the screen, followed by a pair of images, and then a black text probe, all on a white background. I would like to change this to have the stimuli displayed on a white background but I do not want the entire screen to be white. Rather, I would like the background to have a black border surrounding a white rectangle (50%, 80%) in the center of the screen (50%, 50%). Is there an easy way to configure the background to have a shape in the center of it?
