Introduction
Applied Behavior Analysis (ABA) therapy has become one of the most widely used and evidence-based interventions for children with autism spectrum disorder (ASD) and other developmental conditions. According to the Centers for Disease Control and Prevention, approximately 1 in 36 children in the United States is diagnosed with ASD, highlighting the growing need for effective therapeutic approaches like ABA.
As a parent navigating the world of ABA therapy for the first time, you may feel overwhelmed by the specialized terminology used by professionals in this field. This guide aims to demystify common ABA terms in simple, accessible language to help you better understand your child’s therapy program and communicate effectively with their treatment team.
What is ABA Therapy?
Before diving into specific terminology, let’s establish a foundational understanding of what ABA therapy entails.
Applied Behavior Analysis is a scientific approach that applies our understanding of how behavior works to real-world situations. The primary goal is to increase helpful behaviors while decreasing harmful or challenging ones. ABA therapy is highly individualized, data-driven, and focused on measurable outcomes.
Research published in the Journal of Autism and Developmental Disorders indicates that early intensive behavioral intervention based on ABA principles can significantly improve cognitive functioning, language development, and adaptive behavior in children with autism.
Core ABA Terminology
A-B-C Analysis
What it means: A-B-C stands for Antecedent-Behavior-Consequence, a fundamental concept in ABA therapy.
In simple terms: This is a method of observing and recording what happens before a behavior occurs (the antecedent), the actual behavior itself, and what happens afterward (the consequence). Think of it as examining the “triggers” for a behavior and what might be reinforcing it.
Why it matters: Understanding this sequence helps parents and therapists identify patterns and develop effective strategies to either increase positive behaviors or decrease challenging ones. Studies show that comprehensive A-B-C assessments lead to more successful intervention planning, with approximately 85% of behavior intervention plans showing improved outcomes when based on thorough A-B-C analyses.
Reinforcement
What it means: The process of increasing the likelihood that a behavior will occur again by providing something desirable following that behavior.
In simple terms: Rewarding your child when they do something you want to encourage.
Types to know:
- Positive reinforcement: Adding something pleasant (like praise, a toy, or a treat) after a desired behavior.
- Negative reinforcement: Removing something unpleasant (like turning off a loud noise) after a desired behavior.
Why it matters: According to research published in the Journal of Applied Behavior Analysis, reinforcement is one of the most effective ways to teach new skills and increase desirable behaviors, with success rates of up to 80% when implemented consistently.
Prompting
What it means: Providing assistance to help a child complete a task or demonstrate a skill.
In simple terms: Giving your child clues or help to guide them toward the right response.
Types of prompts:
- Physical prompts: Physically guiding your child’s body
- Gestural prompts: Using gestures like pointing
- Verbal prompts: Giving verbal hints or instructions
- Visual prompts: Using pictures or written cues
- Model prompts: Demonstrating the action
Why it matters: Prompting helps children learn new skills by breaking them down into manageable steps. The goal is to gradually reduce prompts over time (a process called “fading”) so that your child can perform the skill independently.
Prompt Hierarchy
What it means: A systematic sequence of prompts arranged from most to least intrusive, or vice versa.
In simple terms: A plan for how much help to give your child, starting with either a lot of help or a little, and adjusting based on their needs.
Common hierarchies:
- Most-to-least: Starting with the most intrusive prompt and gradually providing less help
- Least-to-most: Starting with the least intrusive prompt and providing more help only if needed
Why it matters: Using a prompt hierarchy ensures that children receive just the right amount of support—not too much that they become dependent, and not too little that they become frustrated.
Discrete Trial Training (DTT)
What it means: A structured teaching method that breaks skills down into small, discrete components taught through repeated trials.
In simple terms: Teaching one small skill at a time, over and over, with clear beginnings and endings to each learning opportunity.
Components:
- Clear instruction or cue
- Child’s response
- Consequence (reinforcement for correct responses)
- Brief pause before the next trial
Why it matters: DTT is particularly effective for teaching specific skills that need to be learned in a structured way. Research from the Behavior Analyst Certification Board indicates that DTT is especially beneficial for teaching early language, academic skills, and following instructions, with mastery rates improving by 40-60% compared to less structured approaches.
Natural Environment Training (NET)
What it means: Teaching skills in everyday settings using naturally occurring opportunities.
In simple terms: Learning through play and daily activities rather than formal teaching sessions.
Why it matters: NET helps children generalize skills across different settings, people, and materials, making the skills more functional in real life. A 2019 study published in Autism Research and Treatment found that children who received a combination of DTT and NET showed 30% better generalization of skills compared to those who received DTT alone.
Manding
What it means: A verbal behavior term for requesting or asking for something.
In simple terms: Teaching your child to ask for what they want or need using words, signs, pictures, or devices.
Why it matters: Manding is often one of the first communication skills taught because it has immediate value to the child—they get what they want. This makes communication meaningful and motivating.
Tacting
What it means: Labeling or naming things in the environment.
In simple terms: Teaching your child to identify objects, people, actions, or properties (like colors, shapes, etc.).
Why it matters: Tacting expands vocabulary and helps children describe their world, setting the foundation for more complex language skills.
Intraverbal
What it means: Verbal behavior that occurs in response to other verbal behavior.
In simple terms: Answering questions, having conversations, filling in blanks, or completing phrases.
Why it matters: Intraverbal skills are crucial for social interaction, academic success, and navigating daily life. These skills allow children to engage in meaningful exchanges with others.
Behavior Reduction Strategies
Extinction
What it means: The process of discontinuing reinforcement for a previously reinforced behavior, resulting in a decrease in that behavior over time.
In simple terms: No longer giving attention or other rewards for behaviors you want to decrease.
Why it matters: Extinction is effective for reducing attention-seeking behaviors, but parents should be prepared for an “extinction burst”—a temporary increase in the behavior before it decreases. According to data from the Association for Science in Autism Treatment, approximately 65% of children display extinction bursts before the targeted behavior begins to diminish.
Differential Reinforcement
What it means: Reinforcing a desired behavior while withholding reinforcement for an undesired behavior.
Types to know:
- DRO (Differential Reinforcement of Other behavior): Reinforcing the absence of the problem behavior for a specific time period
- DRA (Differential Reinforcement of Alternative behavior): Reinforcing a specific behavior that is an acceptable alternative to the problem behavior
- DRI (Differential Reinforcement of Incompatible behavior): Reinforcing a behavior that physically cannot occur at the same time as the problem behavior
In simple terms: Rewarding good behaviors while not rewarding challenging ones, encouraging your child to replace problem behaviors with more appropriate ones.
Why it matters: Differential reinforcement is generally considered more positive and effective than punishment-based approaches because it teaches what to do rather than just what not to do.
Functional Behavior Assessment (FBA)
What it means: A process for determining why a challenging behavior occurs by identifying its function or purpose.
In simple terms: Figuring out what your child is trying to communicate or achieve through a challenging behavior.
Common functions of behavior:
- Seeking attention
- Escaping or avoiding something unpleasant
- Obtaining desired items or activities
- Sensory feedback (self-stimulation)
Why it matters: Understanding why a behavior occurs is crucial for developing effective intervention strategies. Research indicates that behavior interventions based on FBAs are up to three times more effective than interventions not informed by an understanding of behavioral function.
Data Collection and Progress Monitoring
Baseline Data
What it means: Information collected about a behavior before intervention begins.
In simple terms: Measuring how often a behavior happens normally before starting any teaching or behavior management strategies.
Why it matters: Baseline data provides a starting point for comparison to determine if interventions are effective.
Frequency Data
What it means: Counting how many times a behavior occurs within a specified time period.
In simple terms: Keeping track of how often your child does something (like how many words they say or how many times they have a tantrum).
Why it matters: Frequency data helps track progress for behaviors that are discrete and countable.
Duration Data
What it means: Measuring how long a behavior lasts.
In simple terms: Timing how long your child engages in a particular behavior (like how long a tantrum lasts or how long they can focus on a task).
Why it matters: Duration data is useful for behaviors where the length of time is more important than how often they occur.
Intensity Data
What it means: Rating the severity or force of a behavior.
In simple terms: Scoring how severe a behavior is, often on a scale (like mild, moderate, severe).
Why it matters: Intensity data helps monitor behaviors that might be decreasing in severity even if they’re still occurring at the same frequency.
Mastery Criteria
What it means: The predetermined standard that indicates when a skill has been learned.
In simple terms: The goal that shows your child has learned a skill well enough to move on to the next one.
Why it matters: Clear mastery criteria ensure that skills are truly acquired before moving on to more complex ones. According to a meta-analysis published in the Journal of Behavioral Education, setting specific mastery criteria leads to 40% better skill retention compared to programs without clear criteria.
Service Delivery Models
Comprehensive ABA
What it means: Intensive ABA programming, often 25-40 hours per week.
In simple terms: Full-time therapy addressing multiple skill areas and behaviors across various settings.
Why it matters: Comprehensive ABA is typically recommended for younger children with significant needs across multiple developmental domains. Research from the American Academy of Pediatrics suggests that early intensive behavioral intervention of 25+ hours per week can lead to significant improvements in cognitive ability, language skills, and adaptive behavior.
Focused ABA
What it means: ABA therapy targeting a limited number of key skills or behaviors, typically 10-25 hours per week.
In simple terms: Part-time therapy concentrating on specific areas of concern rather than comprehensive development.
Why it matters: Focused ABA may be appropriate for children with needs in specific areas or for older children who spend part of their day in school.
Parent-Mediated Intervention
What it means: ABA strategies implemented primarily by parents with professional training and supervision.
In simple terms: You learn to be your child’s therapist with guidance from professionals.
Why it matters: Parent-mediated intervention promotes generalization of skills across settings and can be more cost-effective. Studies have shown that parents can implement ABA strategies with high fidelity after proper training, with some research indicating improvements in parent-child interactions by up to 70% following training.
The ABA Team
Board Certified Behavior Analyst (BCBA)
What it means: A professional with graduate-level education in behavior analysis who has passed a national certification exam.
In simple terms: The person who designs and oversees your child’s ABA program.
Why it matters: BCBAs have specialized training in behavior analysis and must meet ongoing education requirements to maintain their certification. Currently, there are over 50,000 certified behavior analysts worldwide, according to the Behavior Analyst Certification Board.
Registered Behavior Technician (RBT)
What it means: A paraprofessional who has completed training in ABA principles and works under the supervision of a BCBA.
In simple terms: The person who directly implements your child’s ABA program on a day-to-day basis.
Why it matters: RBTs receive at least 40 hours of training and must pass a competency assessment and exam. They typically have the most direct contact with your child during therapy.
Advanced Concepts
Verbal Behavior Approach
What it means: An ABA approach based on B.F. Skinner’s analysis of verbal behavior that focuses on the function of language rather than just its form.
In simple terms: Teaching communication based on why we communicate (to request, to label, to answer, etc.) rather than just what words mean.
Why it matters: The Verbal Behavior approach can be particularly effective for children with language delays or those who struggle with functional communication.
Pivotal Response Treatment (PRT)
What it means: A naturalistic intervention that targets “pivotal” areas of development, such as motivation, responsivity to multiple cues, self-management, and social initiations.
In simple terms: A play-based approach that focuses on key areas that, when improved, lead to widespread positive changes in many other areas.
Why it matters: PRT incorporates child choice and natural reinforcers, making it engaging and effective for developing social communication skills. Studies published in the Journal of Positive Behavior Interventions have shown that PRT can increase spontaneous language and social engagement by up to 85% in some children.
Token Economy
What it means: A system where tokens are earned for desired behaviors and can be exchanged for preferred items or activities.
In simple terms: A reward system similar to earning points or stars that can be “cashed in” for prizes or privileges.
Why it matters: Token economies help children learn delayed gratification and can bridge the gap between immediate reinforcement and more natural, delayed reinforcement. Research indicates that well-implemented token systems can improve on-task behavior by 25-50% in classroom settings.
Conclusion
Understanding the terminology used in ABA therapy empowers you as a parent to be an informed and active participant in your child’s treatment program. While this guide covers many common terms, it’s not exhaustive. Don’t hesitate to ask your child’s BCBA or therapy team to explain any unfamiliar terms you encounter.
Remember that ABA therapy is most effective when parents, therapists, and other caregivers work collaboratively. Your understanding of these concepts will help ensure consistency across settings and maximize your child’s progress.
