**Core Concept**
Systematic desensitization is a behavioral therapy technique used to treat anxiety disorders by gradually exposing patients to feared stimuli in a controlled environment. This approach aims to reduce the associated anxiety response through relaxation techniques and cognitive reappraisal.

**Why the Correct Answer is Right**
Joseph Wolpe, a South African psychiatrist, introduced systematic desensitization in the 1950s. He developed this technique as a way to treat phobias and anxiety disorders by creating a hierarchy of feared stimuli and gradually exposing patients to each item on the list while teaching them relaxation techniques. Wolpe's approach was based on the concept of counterconditioning, where the anxiety response is replaced by a relaxation response through repeated exposure to the feared stimulus. This technique relies on the patient's ability to relax in response to the stimulus, which eventually leads to a decrease in anxiety and avoidance behaviors.

**Why Each Wrong Option is Incorrect**
**Option A:** Seligman, on the other hand, is known for his work on learned helplessness, which is a concept that describes the psychological state of being unable to escape from aversive stimuli, leading to a sense of hopelessness and despair.

**Option C:** Lorenz was an Austrian ethologist who is famous for his work on animal behavior, particularly his observations on imprinting in young birds. His work has no direct connection to systematic desensitization.

**Option D:** Skinner was an American psychologist who is known for his work on operant conditioning, which is a learning process in which behavior is modified by its consequences, such as rewards or punishments. While Skinner's work is relevant to behavioral psychology, he did not introduce systematic desensitization.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that systematic desensitization requires a collaborative effort between the patient and the therapist, as the patient must be able to relax in response to the feared stimulus. The therapist helps the patient create a hierarchy of feared stimuli and guides them through the exposure process, which can be a time-consuming but effective treatment for anxiety disorders.
