Applied behavior analysis

Explanation:

In psychology, applied behavior analysis is a type of therapy that focuses on improving specific behaviors (social skills, communication, reading). This therapy is mainly used when working with Autism Spectrum Disorder

One of the goals of Applied Behavior Analysis is to understand behavior. This approach focuses on how behaviors change or are affected by the environment and how learning takes place.

In this example, Dr. Keiper describes a young child behavior in terms of the events that stimulate, maintain and increase the behavior's likelihood. We can see that she is trying to understand the behavior and she does so in terms of how the environment is affecting the behavior (by stimulating it, maintaining ir or increasing it). Therefore, Dr. Keiper is engaged in Applied behavior analysis.
