Exhaustive ABA Study Guide: Antecedent Strategies, Natural Environment Training, and Behavioral Transitions, and Communication Development
Antecedent Strategies and Proactive Behavioral Management
Antecedent strategies are defined as interventions and preparations implemented before a specific behavior occurs. The goal is to set the environment or the individual up for success by modifying the conditions that precede a behavior.
A specific example discussed involves Eva's morning fruit routine. The parent reported waking up early to have a bowl of strawberries or other preferred fruit ready. The parent tells Eva, "We got , and then we have to get ready. But first, here is your strawberries so you can eat while you wait."
The BCBA noted that while the intent was good, providing the preferred item (strawberries) before the task (getting ready) is technically a "bribe" or is "backwards" in reinforcement terms.
If the child receives the high-preference item first, they may lose the motivation to complete the subsequent task (getting dressed), potentially leading to a refusal behavior once the item is finished because the incentive has already been consumed.
To correct this, the BCBA recommends using a smaller portion of the preferred item or a secondary preferred item (like blueberries) as a reinforcer for completing the task.
The core principle is: First the work, then the "paycheck." This mirrors adult work-life cycles where a paycheck is earned after the work is completed.
The Premack Principle and Tablet Management
The Premack Principle (often referred to as "Grandma's Rule") suggests that a high-probability behavior (something the child wants to do) can be used to reinforce a low-probability behavior (something the child does not want to do).
Example: "First you clean the floor, then you can go to the lake/ocean."
The parent applied this successfully when the children wanted to return to the lake (which Eva calls "the ocean"). They were told they had to clean first, leading to them scrubbing the floors to earn the trip.
Tablet management is currently being handled with this principle. Eva often becomes distracted by the tablet and neglects her meals. The parent now requires "food first, then tablet" to ensure she attends to her meal and finishes eating.
This helps build the skill set of "attending," where the child learns to focus on one primary task (eating) without the constant stimulation of a digital device.
Visual Supports and Time Perception
Visual calendars and schedules are critical for children who do not yet grasp the abstract concept of time (units like minutes or days of the week).
Eva’s brother, Evan, uses a calendar where he marks off days. This helps him visualize how close a specific event is (e.g., therapy days, trips to Target, or trips to the lake).
Eva is beginning to observe this behavior and is starting to understand the concept of waiting through this exposure.
While a child might not understand that "one minute" equals , they can learn through consistent visual cues that the phrase "one more minute" signifies that an activity is coming to an end.
The BCBA recommends a more-time request token board. For a play session, a parent might set a timer for . When that timer goes off, the child can request "more time" up to four times ( each), removing a token each time. When all four tokens are gone, the child visually understands that no more requests can be made.
Program Implementation: Tolerating Denial and Waiting
A specific program titled "Tolerate Denial of Requesting More Time" is being planned for Eva.
The goal is for Eva to tolerate the end of a preferred activity without a tantrum, floor-dropping, or protest when she is told "no more time."
The strategy involves providing two choices for the next transition (e.g., "No more time. Should we go to the room or the bathroom first?") to give the child a sense of agency while maintaining the transition.
Successful responses (transitioning without behavior) must be met with high-magnitude reinforcement.
The BCBA suggests "high-value" items that are exclusive to this specific program. Examples include:
Specific character fruit snacks (e.g., Cinderella or Ninja Turtles gummies).
Store-specific items (Eva particularly likes the brand gummies over name brands).
The "Wait Card" is another visual tool Eva has mastered. She progressed through varying durations of waiting:
(current mastery level)
In the home setting, the wait card can be used when a parent is on a phone call or busy, helping the child understand that the item will be available once the card is removed.
Natural Environment Training (NET) vs. Discrete Trial Training (DTT)
Eva is transitioning from DTT (Discrete Trial Training), which is highly structured and usually occurs at a table, to NET (Natural Environment Training).
NET allows the child to thrive in less structured environments by incorporating learning goals into natural play and daily routines.
Current goals being targeted through NET include:
: Ensuring the phrases are legible and functional (e.g., "Give me the blue paper, please").
Prepositions/Positioning: Practicing "in front of" or "behind" during movement through the clinic (e.g., "Stand in front of Hilli").
Functional Requests: Asking to open shelves or put keys on a hook.
NET makes the work feel like play, preventing the child from becoming fatigued by constant table-top demands.
ABA Scheduling, Schooling, and Fading
Eva is enrolled to start school in August. The graduation from ABA will be a "fading" process rather than an immediate exit to ensure behaviors do not resurface during the transition to a school environment.
There was a discussion regarding reducing ABA hours. The parent inquired about a week ( per week, similar to Evan's schedule).
The BCBA explained that from a clinical and staffing perspective, it is often better to decrease the number of hours per day (e.g., per day, a week) rather than cutting full days.
Rationale for the model:
It maintains a consistent routine for the child without long gaps (e.g., a gap if Thursday-Sunday are off).
It accommodates RBT (Registered Behavior Technician) scheduling, as most staff have Monday-Friday blocks.
Communication and Emotional Expression
Eva is showing emerging expressive communication skills. She is identifying kitchen items such as the refrigerator and sink.
At home, the parents are encouraging her to use words instead of whining or crying when her brother, Evan, bothers her.
Phrases she is successfully using include "leave me alone," "stop," and "can you help me?" (specifically when her tablet needs charging or parental controls appear).
Eva has begun identifying and labeling her own emotions, making statements such as "I'm sad," "I'm mad," or "That's scary" while watching movies.
The speech therapy team is also working on "fill-in-the-blank" tasks and "WH" questions (who, what, where, when, why) to improve her comprehension and conversational skills.
Questions & Discussion
Parent: "Is it possible to do, like, maybe three days a week instead of a full five? Evan's doing a week, going from to ."
BCBA: "Typically, we recommend taking hours away across the board versus by the day. If she's taken away Thursday and Friday, the RBTs would only work three days. Also, it creates a four-day gap of no ABA. I'm not a scheduler, I'm the BCBA, but I'll chat with Katie about the pros and cons."
Parent: "I'll talk it over with Janelle and see what days we could shorten out if the three days isn't possible."
BCBA (Announcement): "Starting Monday, I will be the Clinical Director of this location. We opened our Henderson location, so Christina will be going over there, and I'll take over this location."
Parent: "Congratulations! That's so awesome."
