Discrete Trial Training (DTT)

DTT breaks skills into small, manageable steps and teaches them through structured repetition. Each trial has a clear beginning (instruction), middle (response), and end (reinforcement). For communication, DTT might involve teaching a child to request a preferred item by presenting the item, prompting a verbal or gestural request, and reinforcing successful attempts. This structured approach builds foundational skills that support more complex communication later.

Natural Environment Teaching (NET)

NET takes learning out of the structured setting and into everyday situations. A therapist might use snack time to teach requesting, playground time to practice social greetings, or car rides to work on conversation skills. Because learning happens in context, skills generalize more easily to daily life. NET is especially effective for children who struggle with the rigidity of table-based instruction.

Functional Communication Training (FCT)

FCT identifies why a child engages in challenging behavior and teaches an alternative communication method that serves the same purpose. If a child screams to get attention, FCT might teach them to tap a parent’s shoulder or use a picture card instead. By replacing the behavior with a functional communication skill, FCT reduces problem behaviors while building the child’s ability to express needs.

Pivotal Response Training (PRT)

PRT focuses on pivotal areas of development, including motivation, self-management, and social initiation. Rather than targeting individual behaviors, PRT addresses core areas that produce widespread improvements. A therapist using PRT might follow the child’s interests, offer choices, and reinforce attempts at communication. This approach tends to increase a child’s motivation to interact and communicate.

Visual Supports and Social Stories

Visual supports, including picture schedules, choice boards, and social stories, help children with autism understand expectations and communicate preferences. Social stories use simple language and images to explain social situations, like what happens at a birthday party or how to take turns. These tools reduce anxiety by making abstract concepts concrete and predictable.

Positive Reinforcement

Reinforcement is the foundation of ABA therapy. When a child demonstrates a desired behavior or communication skill, immediate positive reinforcement (praise, preferred activities, tokens) increases the likelihood they will repeat it. The key is identifying what motivates each individual child and delivering reinforcement consistently. Over time, natural reinforcers like social interaction often replace tangible rewards.

Generalization Strategies

Teaching a skill in one setting is only the beginning. ABA therapists use generalization strategies to ensure skills transfer across environments, people, and situations. This might involve practicing greetings with multiple people, using communication skills in different locations, or having parents and teachers reinforce the same behaviors. Generalization ensures that progress in therapy translates to real-world improvement.
