What is ABA therapy, and how does it work?
Applied behavior analysis therapy is a proven approach for helping children with autism build new skills and reduce behaviors that can make learning more difficult. Through our Pennsylvania ABA therapy, children diagnosed with ASD can improve their communication, develop self-care routines, and learn emotion regulation skills. Our ABA therapists use positive reinforcement and personalized strategies to support each child’s growth. We work closely with families to help children reach their goals and build the skills they need for the future.
Does ABA therapy work for autism?
Yes! Every child with autism is unique, and some children experience more significant progress with ABA therapy than others. However, studies show that children who receive two or more years of intensive behavioral interventions, such as ABA therapy, can often participate in school and social activities at the same level as their peers.
Does ABA therapy mean my child is “stuck” at a table all day repeating the same tasks?
No way! At Action Behavior Centers, we create an exciting environment for learning. While sitting at a table may be a developmental goal for school readiness, there are so many other skills to learn and fun to have.
Our autism treatment centers feature designated “Eats and Crafts” spaces that are used daily for exciting activities. Circle Time, another daily event, brings therapists, BCBAs, and children together to sing, laugh, and learn. Children can also participate in energetic, therapist-led activities like group exercises and sensory rooms.
