+Real world application: exposure therapies. The distinctive element of the two process model is the idea that phobias are maintained by avoidance of the phobic stimulus. This is important in explaining why people with phobias benefit from being exposed to the stimulus. Once the avoidance behaviour is prevented it ceases to be reinforced by the experience of anxiety reduction and avoidance; it declines. The phobia is the avoidance behaviour so when avoidance is prevented, the phobia is cured. This shows the value of the two process approach; it identifies a means of treating phobias.
