Form is what behavior looks like; function is the relation maintaining it
Two children may both drop to the floor, yet the relevant consequences can differ. For one child the response may reliably postpone a difficult task. For another it may produce attention or access to an activity. Some behavior persists through automatic reinforcement generated by the response itself. More than one contingency may operate, and contingencies can change across settings.
This is why “attention seeking,” “sensory,” or “escape” should not be assigned from appearance or intuition.
What A–B–C observation means
Antecedent refers to what happened immediately before. Behavior must be described in observable terms. Consequence means what happened immediately after—not whether it was good or bad. Repeated records may reveal correlations worth investigating. They do not, by themselves, demonstrate that a consequence caused or maintains the behavior.
Useful notes avoid interpretation:
- Write “adult presented the worksheet” instead of “he was pressured.”
- Write “child pushed the paper off the table” instead of “he became defiant.”
- Write “worksheet was removed for two minutes” instead of “he got what he wanted.”
Why consequences matter
In behavior analysis, reinforcement means that a consequence increases the future probability of a response under relevant conditions. Positive and negative describe whether a stimulus is added or removed; they do not mean good and bad. Attention, access, escape, and automatic reinforcement are broad categories—not diagnoses and not complete explanations.
From hypothesis to helpful support
A qualified practitioner combines interview, direct observation, records, and—when appropriate and safe—structured analysis. A function-based plan may adjust antecedent conditions, teach functional communication or another replacement response, make that response efficient, reinforce it, and track both behavior and quality-of-life outcomes.
Stopping a response without teaching an effective alternative can remove the child’s current route without building a better one.
Severe self-injury, aggression, elopement, or other immediate risks need qualified assessment and a safety plan. Families should not attempt an experimental functional analysis on their own.
