Natural Environment Teaching (NET) Notes

Learning Stages & Instructional Outcomes

  • 4 sequential stages of learning/teaching in ABA
    • Acquisition – initial learning of a skill
    • Fluency – increasing speed/accuracy
    • Discrimination – differentiating when/where to use the skill
    • Generalization – using the skill across people, settings, & stimuli
  • Purpose of generalization
    • Promote use of skills in everyday life & environments
    • Establish stimulus control so natural cues evoke target behaviors
    • Increase adaptive performance outside contrived settings

Natural Environment Teaching (NET) – Core Ideas

  • ABA‐based instruction delivered in real‐life settings rather than at a table or single workstation
  • Teacher/RBT capitalizes on naturally occurring situations & reinforcers
  • Maintains alignment with client’s program book (goals/objectives remain the same)
  • Often necessary for skills that are hard to replicate in a clinic (e.g., toothbrushing in an actual bathroom)
  • Can include aids from clinic (token boards, visuals) to scaffold learning in vivo

Skills Especially Suited for NET

  • Functional communication (manding/tacting)
  • Social interaction & play skills
  • Self-care routines (toothbrushing, bathing)
  • Homemaking / daily living (laundry, cooking)
  • Community navigation (shopping, money use)
  • Gross-motor play (swinging, sliding, running)

Incidental Teaching – Overarching NET Strategy

  • Definition: Systematically using unplanned, naturally occurring opportunities to teach targeted behaviors
  • Less pre-structured, more responsive to child’s motivation & environment
  • Still data-driven; teacher tracks progress toward IEP/plan goals

MAND-Model Procedure (within Incidental Teaching)

  1. Teacher observes learner’s interest in an item/activity
  2. Teacher models the correct language/response (“Push me, please”)
  3. Learner is prompted/required to imitate or approximate the model
  4. Natural reinforcer is delivered immediately (swing pushes, access to toy)

Case Study 1 – Beatrice (Early Language Learner)

  • Schedule: 20 hrs/week clinic + 20 hrs/week home NET
  • Clinic targets: manding, tacting, listener responding
  • Home NET capitalizes on outdoor play & pet cat “JoJo”

Original Mand Targets (Partial List)

  • “kitty / JoJo”
  • “apple”
  • “iPad”
  • “slide”
  • “jump”
  • “water”
  • “swing”

NET-Generated/Generalized Mands

  • “puppy” (generalized from “kitty” with both animals present)
  • “bubbles” (contrived by RBT withholding bubbles)
  • “banana” (emerged when no apple available)
  • “play” (modeled by siblings, reinforced by RBT)
  • “push” (needed on swing)
  • “go / outside” (context not available in clinic)
  • “mud” (incidental teaching exemplar)

Detailed Incidental Teaching Sequence – “Mud”

  1. Beatrice swinging; discovers puddle → squeals (identify motivation)
  2. RBT lets her splash a few times (verify durability of reinforcement)
  3. RBT halts swing just before feet hit puddle; prompts “Say ‘mud’!”
  4. Learner says “mud” → immediate release into splash (natural reinforcer)
  5. Skill maintained next day with parents; generalized inside house → spontaneous “mud” mand to RBT

Case Study 2 – Gordon (10-yr-old with ASD)

  • Language in short sentences; deficits in waiting & tone with peers
  • Intervention mix: 3 individual sessions/week + 2 NET cafeteria/playground sessions
  • Key goals: appropriate tone when making requests; waiting turn in games

Cafeteria Incident (Ketchup)

  1. Gordon (gruff tone): “Pass the ketchup.” → Peer annoyed, refuses
  2. Potential escalation (peer is naïve; treats Gordon like any other 10-yr-old)
  3. RBT implements MAND-model
    • Gains attention: “Pass the ketchup, please.” (model)
    • Gordon protests (“I did ask!”) – shows confusion about tone/ politeness cue
    • RBT increases prompt: “Say it like me.”
    • Gordon modifies tone; peer passes ketchup (RBT ensures follow-through)
  4. Outcomes
    • Teaches Gordon nuance beyond word usage (prosody, politeness)
    • Provides peer with live model on de-escalation, fostering inclusion

Obstacles & Risks in NET

  • Privacy & Confidentiality
    • Informed consent must specify community/home training
    • RBT must know what info can/cannot be shared with teachers, bystanders
  • Funding / Reimbursement Constraints (handled by BCBA/agency)
  • Safety Concerns
    • Client behaviors: aggression, elopement, SIB, false accusations
    • Environmental variables: roads, animals, strangers
    • Reduced control compared to clinic
  • Observer Reactions
    • Naïve peers/ public may escalate or interfere

Implementation Tips & Best Practices

  1. Verify informed consent for each natural setting
  2. Pre-visit & research the site (traffic, animals, typical crowd, hazards)
  3. Build a hierarchy of natural settings
    • Start with semi-controlled (group room, classroom, home)
    • Progress to less structured (park, store) only after mastery & instructional control
  4. Ensure high baseline accuracy & compliance before NET session
  5. Bring extra/high-value reinforcers for unexpected challenges
  6. Rehearse scenarios in clinic or during transit
    • Scripts for initiating play, requesting help, polite forms
    • Panic signal or escape option for learner
  7. Plan for worst-case events
    • Additional staff or parent present
    • Shorter initial durations; clear exit strategy
  8. Debrief & feed observations back to BCBA → adjust discrete-trial materials or goals

Ethical, Philosophical & Practical Implications

  • Empowering clients: Real-world competence > rote table skills
  • Promotes dignity through participation in typical routines (e.g., shopping, park play)
  • Balances autonomy with safety; respects least-restrictive environment principles
  • Encourages collaboration with families & community while safeguarding confidentiality

Connections to Foundational ABA Principles

  • Stimulus Control: NET ensures natural SDs (mud puddle, peer request) evoke correct responses
  • Motivating Operations: Uses naturally strong MOs (desire to splash, need for ketchup)
  • Generalization & Maintenance: Direct practice across people, settings, stimuli → durable behavior change
  • Shaping & Prompt Fading: E.g., RBT escalating prompt from model → “Say it like me” → independent polite request

Key Terminology Quick-Reference

  • NET (Natural Environment Teaching): ABA instruction occurring in real-life contexts
  • Incidental Teaching: Leveraging naturally occurring events for instruction
  • MAND: A request controlled by motivation (e.g., saying “mud” to get splash)
  • MAND-Model: Teacher models the desired mand, then prompts imitation
  • Stimulus Control: Behavior reliably occurs in presence of the correct cue
  • Instructional Control: Learner’s cooperation with instructor; prerequisite for safe NET

Numerical References

  • Clinic vs. home hours for Beatrice: 20 + 20 hours/week
  • Gordon’s weekly schedule: 3 individual sessions, 2 NET sessions
  • Development timeline for Gordon’s language growth: 2 years

Summary Takeaways

  • NET bridges clinic gains to life functionality; requires careful planning, strong control, informed consent
  • Incidental teaching & MAND-model allow RBTs to seize motivation moments for rapid language/social growth
  • Real-world settings reveal nuanced barriers; data from NET guides refinement of discrete-trial programs
  • Ethical practice in NET involves safeguarding privacy, ensuring safety, and promoting client dignity at all times
