Just touch the top back part of your head and notice the feeling that is left behind when you move your hand away. It will remain for some time without a lot of attention.
Practice doing that when you PhotoRead. touch that part of the head to place the tangerine there and then just get on with PhotoReading. You don't have to keep thinking of it but if you find yourself distracted easily by stuff going on around you or your mind wandering, bringing your awareness back to the tangerine will help you to refocus.
