Next, you would move the individual onto the fear hierarchy in which the individual would move through the stages from thinking of the stimuli in their head, once they are comfortable with this then they would go to seeing pictures of the stimuli, then they would move onto being in the same room as the stimuli if that were the case and eventually be able to overcome the phobia to touch or be in the situation with the stimuli that caused them the anxiety. An example of this is McGraths study of Lucy and her phobia of loud noises through which the use of party poppers and balloons was used to help her overcome her fear. By using the relaxation techniques, whilst working through the fear hierarchy, she was eventually, by the 10th
