Core Concepts Review

Whether you are new to FBA or a seasoned professional, summer is an excellent time to revisit foundational concepts. This refresher reinforces the thinking patterns that drive effective intervention.

The Fundamental Question

Function-based thinking starts with a shift in perspective. Instead of asking "How do I stop this behavior?" we ask:

"What is this behavior doing FOR the student?"

Behavior that persists is behavior that works. Understanding what it achieves helps us teach more appropriate alternatives.

The Four Functions Reviewed

Attention (Social Positive)

Behavior produces attention from others - positive or negative

Signs: Occurs when attention is low; student looks at adults; stops when attention given

Escape (Social Negative)

Behavior removes or delays demands, tasks, or situations

Signs: Occurs during demands; stops when demand removed; rare during preferred activities

Tangible (Access)

Behavior produces access to items, activities, or privileges

Signs: Occurs when item restricted; stops when item given; specific to certain items

Sensory (Automatic)

Behavior produces internal reinforcement regardless of environment

Signs: Occurs across settings; consistent even when alone; provides sensory input

Writing Hypothesis Statements

A hypothesis statement synthesizes your assessment data into a testable prediction:

"When [antecedent/trigger], [student] engages in [behavior] in order to [function/consequence]."

Example Hypothesis

"When presented with independent reading tasks, Marcus engages in verbal refusal and putting his head down in order to escape the reading demand."

Matching Intervention to Function

Function Intervention Focus
AttentionTeach appropriate attention-seeking; provide attention for positive behavior; minimize attention for problem behavior
EscapeTeach appropriate break requests; modify task difficulty; provide breaks contingent on appropriate behavior
TangibleTeach appropriate requesting; establish earning systems; do not provide items after problem behavior
SensoryProvide appropriate sensory alternatives; enrich environment; teach replacement behaviors that meet sensory needs

Function First, Always

The most common intervention mistake is selecting strategies without identifying function. A consequence-based approach without function identification is essentially guessing. Take time to understand the why before selecting the how.

Take Action

Put what you've learned into practice with these resources.

Key Takeaways

  • All behavior serves a function - attention, escape, tangible, or sensory
  • The same behavior can serve different functions for different students
  • Function determines intervention - matching function to strategy is essential
  • Hypothesis statements connect antecedent, behavior, consequence, and function
  • Function-based interventions outperform consequence-only approaches
