Behavior & ABC
What is behavior?
An observable and measurable action a person does.
What are the four commonly identified functions of behavior?
Attention, escape, access to tangibles or activities, and automatic reinforcement (sensory consequences).
What is an antecedent?
Something that happens immediately before a behavior.
What does it mean to use a proactive strategy?
Taking steps in advance to prevent challenges and make appropriate behavior more likely.
What is positive reinforcement?
Adding something after a behavior that increases the likelihood of that behavior happening again.
What does ABC stand for
Antecedent, Behavior, Consequence.
A student calls out, and the teacher immediately talks to them each time. Which function might be involved?
Attention
Name one example of a setting event that could affect a student's behavior at school.
Poor sleep, illness, a change in routine, or a stressful morning.
A student struggles when switching from recess to math. Name one proactive strategy.
Give a transition warning, use a visual schedule, or provide a clear transition cue as appropriate to the student's plan.
Which is more specific: “Good job!” or “I like how you started your work right away”? and why?
“I like how you started your work right away,” because it identifies the behavior being praised.
The teacher says, “Take out your math book.” The student throws the book. What is the behavior?
Throwing the book.
A student rips a worksheet, and the worksheet is taken away. Which function might be involved?
Escape from a task or demand.
A teacher announces a surprise fire drill, and a student begins pacing. What is the antecedent?
The announcement of the fire drill.
A student has difficulty completing a long worksheet. What could you do proactively?
Break the task into smaller chunks, clarify expectations, or offer planned breaks if supported by the student's plan.
A student raises their hand instead of calling out. What could the para say to reinforce this skill?
"Great job raising your hand to share your idea!”
A student is told to clean up and cries, the para removes the cleanup demand. Identify the antecedent, behavior, and consequence.
Antecedent — cleanup instruction. Behavior — crying. Consequence — the demand is removed.
A student screams when a tablet is taken away, and the tablet is returned. What function might this behavior serve?
Access to a tangible or preferred activity.
A student slept poorly and becomes upset when asked to complete a difficult assignment. Which could be the setting event, and which is the antecedent?
Poor sleep may be a setting event; the assignment instruction is the immediate antecedent.
A student often becomes frustrated when work feels too difficult. What should the para consider before frustration begins?
Task difficulty, appropriate instructional support, communication options, pacing, and individualized accommodations or supports.
A student receives praise every time they line up appropriately, but the behavior does not increase. Does that mean praise is functioning as a reinforcer?
Not necessarily. Reinforcement is determined by its effect on future behavior, so the team should review the student's response and plan.
Why is it important to record what happened before and after a behavior instead of simply writing “the student was being difficult”?
Objective ABC information helps the team identify patterns and develop appropriate supports without relying on assumptions or judgments.
A student repeatedly hums while alone, and the humming continues regardless of social attention. What function might be involved, and can you know for sure from this information alone?
Automatic reinforcement may be involved, but more observation and assessment may be needed to determine the function.
Two students receive the same instruction, but only one becomes upset. Why might the same antecedent lead to different responses?
Students have different needs, learning histories, skills, and setting events. The same event may affect each student differently.
A student has a history of becoming upset during noisy assemblies. What is a proactive plan the team might consider?
Plan ahead with the team for appropriate noise supports, preparation, visual information, seating, or an agreed-upon break option, based on the student's needs and plan.
A para praises a student only after the student has become very upset and then calmed down. How could the para better support the student proactively?
Provide timely, specific reinforcement for appropriate skills as they occur, according to the student's plan, rather than waiting for escalation.
