Parenting is one of the most rewarding roles in life, but it can also feel overwhelming at times. Children, whether neurotypical or neurodivergent, experience big emotions and test boundaries as they grow. While some behaviors are simply part of childhood, others—like frequent tantrums, refusal to follow directions, or aggression—can leave parents feeling frustrated and uncertain about how to respond.
Applied Behavior Analysis (ABA) offers practical, research-based tools that parents can use every day to better understand their children, reduce stress, and help them thrive. This article provides a comprehensive overview of core ABA principles—functions of behavior, reinforcement, and functional communication training (FCT)—and explains how parents can apply them at home in ways that work for their unique family.
Understanding Why Children Behave: The Four Functions
One of the most empowering ideas in ABA is that all behavior serves a purpose. Kids don’t misbehave “just because.” Behavior is communication—it’s how children let us know what they need or want, especially when words aren’t enough.
Research identifies four main reasons, or functions, for behavior (Iwata, DeLeon, & Roscoe, 2017):
1. Attention
Children often act out to get attention, whether positive or negative. If a child yells and a parent responds—even with “Stop that!”—the child has still achieved their goal of connection.
Example: A child shouts from another room until a parent comes in.
What to do: Instead of reacting to shouting, wait for calm behavior or a polite request and respond immediately. Praise calm communication.
2. Escape or Avoidance
Sometimes kids try to get out of things they don’t like—chores, homework, brushing teeth. Avoidance can also happen if a task feels too hard.
Example: A child has a meltdown when asked to clean their room.
What to do: Break the task into smaller steps and reinforce each step. Teach them to say, “Can I have help?” or “Can I do half now and half later?”
3. Access to Tangibles
Children may misbehave to get something they want, like candy, toys, or screen time.
Example: A toddler throws herself on the floor in the store to get a toy.
What to do: Don’t give in to tantrums. Instead, teach and reward asking politely. Later, plan ahead—bring a toy from home, or set clear expectations before entering the store.
4. Automatic or Sensory
Some behaviors feel good in themselves, like rocking, humming, or spinning. These are self-soothing or sensory-seeking behaviors.
Example: A child hums loudly while doing homework.
What to do: If the behavior isn’t harmful, allow it. If it interferes with daily life, provide an alternative sensory activity (e.g., a stress ball, weighted lap pad).
Reinforcement: Building the Behaviors You Want
One of the simplest but most powerful tools in ABA is reinforcement—rewarding behaviors so they happen more often. Reinforcement is not bribery; it’s about showing children that good behavior pays off.
Types of Reinforcement Parents Can Use
Social reinforcement: Smiles, hugs, praise (“I love how you helped your brother!”).
Activity-based reinforcement: Extra story at bedtime, choosing a family game.
Tangible reinforcement: Stickers, tokens, or small treats.
Natural reinforcement: The direct result of a request (asking for water gets water).
Differential Reinforcement
Differential reinforcement means rewarding the good behavior while not rewarding the problem behavior.
DRA (Alternative): Reinforce asking for a toy instead of grabbing it.
DRI (Incompatible): Reinforce sitting at the table (cannot be done while wandering).
DRO (Other): Reinforce periods when the problem behavior doesn’t happen.
DRL (Low Rates): Reinforce when a behavior happens less often (e.g., fewer interruptions).
Research shows differential reinforcement reduces challenging behavior while teaching better habits (Suarez & McBride, 2020).
Functional Communication Training (FCT): Giving Kids Better Tools
Many problem behaviors happen because kids don’t know how—or don’t have the confidence—to ask for what they need. Functional Communication Training (FCT) teaches children to replace behaviors like tantrums or aggression with clear communication.
Examples:
Younger children: Teach “all done” or use a picture card.
Older children: Teach “I need a break” or “Can I have more time?”
Non-verbal children: Use sign language or speech devices.
FCT works because it addresses the function of the behavior and gives the child a more effective way to meet their needs. Studies show FCT reduces problem behavior in both neurotypical and neurodivergent children when parents use it consistently (Gerow et al., 2020).
Everyday Scenarios and Strategies
1. Bedtime Battles
Problem: Child resists bedtime routines.
Why: Escape from bedtime tasks.
Solution: Create a predictable routine. Reinforce staying in bed (stickers, morning praise). Teach them to ask for “one more story” instead of stalling.
2. Mealtime Struggles
Problem: Child throws food.
Why: Escape or attention.
Solution: Praise calm eating and reinforce sitting at the table. Teach them to say, “All done.” Ignore throwing.
3. Public Outings
Problem: Tantrums in the store.
Why: Access to tangibles.
Solution: Plan ahead. Reinforce polite asking with small rewards. If tantrums occur, stay calm and don’t give in. Praise calm behavior when it returns.
4. Sibling Conflicts
Problem: Fighting over toys.
Why: Access to tangibles and attention.
Solution: Reinforce sharing and calm words. Teach phrases like “Can I have a turn?” Give extra praise when they resolve conflict without yelling.
Common Mistakes Parents Make
Inconsistency. Giving in sometimes teaches kids to keep trying problem behavior.
Delayed reinforcement. Waiting too long weakens the connection—praise or reward should be immediate.
Accidentally reinforcing problem behavior. Attention—even scolding—can make behavior stronger.
Not teaching alternatives. If you remove problem behavior but don’t give a replacement (like FCT), kids will find another way.
Building Consistency Across Caregivers
Children learn best when all adults respond the same way. If one parent enforces bedtime rules but another gives in, progress stalls. Discuss strategies as a family. Share clear expectations with babysitters, grandparents, and teachers. Research shows caregiver alignment reduces confusion and helps children generalize skills (Shire, Gulsrud, & Kasari, 2017).
Why These Strategies Work for All Children
While ABA is best known for supporting children with autism, these strategies help every child. Neurotypical children benefit from clear expectations, positive reinforcement, and communication skills just as much as neurodivergent children. The difference is in tailoring strategies to each child’s developmental level, strengths, and needs.
Take-Home Steps for Parents
Observe the function. Ask: “What is my child trying to get or avoid?”
Reinforce the positive. Catch good behavior and reward it.
Teach communication. Give your child the words, signs, or cards to express needs.
Be consistent. Respond the same way every time.
Celebrate small wins. Even progress like asking instead of whining deserves recognition.
Conclusion
Parenting doesn’t come with an instruction manual, but ABA principles offer practical tools for creating calmer routines, stronger communication, and happier family life. By learning why behaviors happen, reinforcing positive actions, and teaching children better ways to communicate, parents can reduce stress while giving their children skills that last a lifetime.
