How Exposure And Response Prevention (ERP) Therapy Came To Be

Share This Post

Imagine you’re afraid of spiders. You know that most spiders are harmless, but when you see one, your heart races, you start to sweat, and you feel an overwhelming urge to run away or kill it. This kind of fear can be very intense and hard to manage. Now, imagine that someone tells you that the best way to overcome your fear is to face it head-on, a little at a time until it doesn’t scare you so much anymore. This approach is part of a type of therapy called Exposure and Response Prevention (ERP).

ERP is a technique used primarily to treat Obsessive-Compulsive Disorder (OCD) and other anxiety disorders. It involves exposing someone to the source of their fear or anxiety in a controlled way and then preventing the usual response, such as avoiding or performing a compulsive behavior. Over time, this helps the person to become less sensitive to their fear.

But who came up with this idea? Who was the first person to use exposure and response techniques in therapy? Let’s dive into the history and find out.

Early Foundations of Behavior Therapy

To understand the origins of ERP, we need to go back to the early 20th century, when psychologists were just beginning to explore new ways of treating mental health issues. At that time, the dominant approach to therapy was psychoanalysis, developed by Sigmund Freud. Psychoanalysis focuses on exploring a patient’s unconscious mind and early childhood experiences to understand and resolve psychological problems.

However, some psychologists were interested in a more direct approach to treatment. They began to study how people’s behaviors could be changed through learning and conditioning. This led to the development of behaviorism, a school of thought that focuses on observable behaviors rather than internal mental states.

Ivan Pavlov and Classical Conditioning

One of the key figures in the development of behaviorism was Ivan Pavlov, a Russian physiologist. In the early 1900s, Pavlov conducted experiments with dogs that led to the discovery of classical conditioning. He found that if he rang a bell just before feeding the dogs, they would eventually start to salivate at the sound of the bell alone, even when no food was present. This demonstrated that behaviors could be learned through association.

Pavlov’s work laid the groundwork for understanding how fears and other emotional responses could be conditioned, or learned, through experience. However, it was still a long way from the kind of therapy we now know as ERP.

John B. Watson and the Little Albert Experiment

Building on Pavlov’s work, American psychologist John B. Watson conducted one of the most famous and controversial experiments in the history of psychology: the Little Albert experiment. In 1920, Watson and his assistant, Rosalie Rayner, set out to demonstrate that emotional responses could be conditioned in humans as well.

They worked with a baby named Albert, who initially showed no fear of a white rat. However, by pairing the presentation of the rat with a loud, frightening noise, they were able to condition Albert to become afraid of the rat. This experiment provided strong evidence that fears could be learned through conditioning.

Although Watson’s experiment was groundbreaking, it did not include the idea of exposure and response prevention. It would take several more decades for this concept to be developed.

Mary Cover Jones and the First Exposure Therapy

Mary Cover Jones is often credited with conducting the first systematic desensitization, a precursor to modern ERP. In 1924, she worked with a young boy named Peter, who had a fear of rabbits. Jones used a technique called “direct conditioning,” which involved gradually exposing Peter to a rabbit while he was in a relaxed state.

Jones started by having Peter engage in enjoyable activities while a caged rabbit was placed at a distance. Over time, she moved the rabbit closer and closer, while ensuring that Peter remained calm. Eventually, Peter was able to touch and hold the rabbit without fear.

This process of gradually increasing exposure to the feared object while preventing an anxious response is very similar to the principles of ERP. Mary Cover Jones’ work was a significant early contribution to the development of exposure-based therapies.

Joseph Wolpe and Systematic Desensitization

In the 1950s, South African psychiatrist Joseph Wolpe expanded on the work of Mary Cover Jones and developed a method called systematic desensitization. Wolpe’s approach involved three main steps:

  1. Relaxation Training: Teaching the patient techniques to achieve a state of deep relaxation.
  2. Creating a Fear Hierarchy: Working with the patient to list situations related to their fear, ranked from least to most anxiety-provoking.
  3. Gradual Exposure: Gradually exposing the patient to the feared situations, starting with the least frightening, while they practice relaxation techniques.

Wolpe believed that by pairing relaxation with gradual exposure to the feared object or situation, patients could learn to remain calm and their fear would diminish over time. Systematic desensitization became a widely used and effective treatment for phobias and other anxiety disorders.

Victor Meyer and Exposure and Response Prevention

While systematic desensitization was effective for many people, it was not as successful for those with Obsessive-Compulsive Disorder (OCD). In the 1960s, British psychologist Victor Meyer introduced a new approach specifically for treating OCD: Exposure and Response Prevention (ERP).

Meyer’s method involved exposing patients to situations that triggered their obsessive thoughts while preventing them from engaging in their usual compulsive behaviors. For example, someone with a fear of contamination might be asked to touch a dirty object and then refrain from washing their hands.

Meyer found that by preventing the compulsive response, patients could gradually learn that their feared outcomes did not occur and that their anxiety would decrease over time. This approach was particularly effective for OCD, where the compulsions often serve to maintain the cycle of anxiety.

ERP Today

Today, ERP is considered one of the most effective treatments for OCD and is also used to treat other anxiety disorders, such as panic disorder and social anxiety disorder. The principles of ERP are based on the work of early behaviorists like Pavlov, Watson, and Jones, as well as later developments by Wolpe and Meyer.

Here at West Coast Anxiety, one of our most used approaches is ERP. We work with the patient to identify their specific fears and compulsions, then create a plan for gradually exposing the patient to these fears while preventing the compulsive behaviors. Over time, the patient learns to tolerate the anxiety and the compulsions become less necessary.

ERP remains a vital tool in the treatment of OCD and other anxiety disorders, offering hope and relief to many who struggle with these conditions. By understanding its history, we can appreciate the dedication and innovation of the psychologists who paved the way for this effective and life-changing therapy.
