Differences Between Natural Environment Training (NET) and Discrete Trial Training (DTT)

In the realm of Applied Behavior Analysis (ABA) therapy, two prominent teaching methodologies stand out for their effectiveness in supporting children with Autism Spectrum Disorder (ASD): Natural Environment Training (NET) and Discrete Trial Training (DTT). Both approaches offer unique benefits and are used extensively in therapeutic settings, including those provided by leading institutions like Chicago ABA Therapy. Understanding the differences between these methods can help parents, educators, and therapists make informed decisions about the most appropriate strategies for individual children.

What is Discrete Trial Training (DTT)?

Discrete Trial Training (DTT) is a structured ABA technique that uses a series of trials to teach a specific skill or behavior. Each trial, or teaching attempt, comprises three parts: an instruction, a prompt or support, and a consequence. The process is systematic and repetitive, designed to reinforce learning through clear, measurable actions and outcomes.

Key Characteristics of DTT:

  • Structured Environment: DTT typically occurs in a controlled setting where distractions are minimized, making it easier for the child to focus on the task.
  • Clear Instructions and Prompting: Therapists provide explicit instructions and may use prompts to guide the child’s responses. These prompts are gradually faded as the child gains independence.
  • Immediate Feedback: After each trial, the child receives immediate feedback, which can be positive reinforcement for a correct response or corrective feedback for an incorrect one.
  • Skill Acquisition in Steps: Skills are broken down into smaller, manageable components, and each component is taught individually until mastery.

What is Natural Environment Training (NET)?

Natural Environment Training (NET) is an ABA approach that emphasizes teaching skills within natural settings and through naturally occurring activities. This method leverages the child’s immediate interests and activities to facilitate learning, making the process more engaging and applicable to real-life situations.

Key Characteristics of NET:

  • Learning in Natural Settings: NET is conducted in environments where the child naturally spends time, such as at home, in a park, or during playtime.
  • Incorporation of Child’s Interests: Instructions and learning opportunities are based on the child’s interests and activities, which helps to keep them motivated and engaged.
  • Generalization of Skills: By learning in various settings with different stimuli, children are more likely to generalize skills across different environments and situations.
  • Focus on Interaction: NET often involves more interaction with others, which can enhance communication skills and social interactions.

Comparing DTT and NET: Strengths and Limitations

While both DTT and NET are effective, their differences make them suitable for varying needs and learning stages:

  • Suitability for Early Learners: DTT is often preferred for children who are just beginning to develop basic skills. The structured nature of DTT helps establish a foundation for learning.
  • Engagement and Motivation: NET tends to be more engaging for children as it involves their interests and real-life objects, which can enhance motivation and enjoyment.
  • Skill Generalization: NET is superior in promoting the generalization of skills because it teaches in diverse settings and situations, unlike the more controlled environment of DTT.
  • Complex Skill Acquisition: DTT is particularly effective for teaching complex or challenging skills that require intense focus and repetition.
  • Social and Communication Skills: NET provides better opportunities for children to develop social and communication skills due to its interactive nature and use of natural social settings.

Choosing between Natural Environment Training (NET) and Discrete Trial Training (DTT) depends on the specific needs, strengths, and goals of each child.

"Chicago ABA Therapy is a boon for special needs kids and parents. They take a play-based, personalized approach and meet the kids where they are. They also go above and beyond - our ABA therapist took time to make sure we as parents understood every aspect of our child's experience, understood how to read his progress reports and generally made us feel a part of his therapy. My child loved all his therapists. Highly recommend the team!"

"We were so happy with our experience with Chicago ABA. We began working with them when our son was almost 4, a few months after his autism diagnosis. It was such an amazing team to work with - everyone was professional, responsive, flexible, and worked so hard for our son to meet his goals, which he did beautifully. We worked together for almost 2 years before he left for kindergarten, and in that time period he met almost all of his goals. We went through several bumps in the road with behavioral difficulties, and the Chicago ABA team did an amazing job helping us problem solve, try new strategies and think of ways to translate those strategies at home. We couldn't recommend them more highly - anyone who works with Chicago ABA will be lucky to have the experience!"
