Extinction

From WikiMD's Wellness Encyclopedia

Extinction is a term used in psychology and behavioral science to describe the process by which a conditioned response gradually ceases to occur over time. This process is often used in various forms of therapy and behavior modification programs.

Overview[edit | edit source]

In the field of psychology, extinction is considered a form of learning. It occurs when a conditioned stimulus is repeatedly presented without the unconditioned stimulus, leading to a decrease in the conditioned response. This process is often used in behavioral therapy to help individuals unlearn harmful or unwanted behaviors.

Process[edit | edit source]

The process of extinction begins when a conditioned stimulus (CS) is repeatedly presented without the unconditioned stimulus (US). Over time, the conditioned response (CR) to the CS decreases and eventually disappears. This is because the association between the CS and US is weakened, leading to the extinction of the CR.

Applications[edit | edit source]

Extinction is used in various forms of therapy and behavior modification programs. For example, in exposure therapy, a form of cognitive behavioral therapy, individuals are exposed to a feared stimulus in a safe environment until their fear response is extinguished. Similarly, in systematic desensitization, individuals are gradually exposed to a feared stimulus while practicing relaxation techniques, leading to the extinction of the fear response.
