Final answer:
The correct treatment for phobias is option 3, where systematic desensitization exposes a person to a gradient of feared stimuli over time to reduce the fear response. In allergy treatment, desensitization therapy involves gradual exposure to allergens.
Step-by-step explanation:
Proper Treatment for Phobias
The correct option that describes a treatment for phobias is the following: Systematic desensitization exposes a person, over time, to a gradient of feared stimuli. This type of therapy involves gradually introducing the patient to the feared object or context without any danger, to help desensitize them to the fear response over a period of time. It differs from implosive therapy, which could involve exposing a person to the specific unconditioned stimulus that causes fear, possibly in a more direct and intense way.
Desensitization therapy, when used in the context of allergies, also involves a gradual exposure to the allergen in question. This helps the immune system become more tolerant and reduces sensitivity. The role of epinephrine in the treatment of hypersensitivity reactions is crucial in emergency situations as it quickly reduces the body's allergic response.
