Understanding establishing operations is essential for BCBA candidates and practicing behavior analysts. These environmental events temporarily alter the reinforcing effectiveness of specific consequences, making certain behaviors more likely to occur. This guide breaks down the concept with clear definitions, practical examples, and exam-focused strategies.

What is an Establishing Operation? A Foundational Definition
An establishing operation (EO) is a type of motivating operation that momentarily increases the value of a particular reinforcer. This temporary change in reinforcer effectiveness makes behaviors that have previously accessed that reinforcer more likely to occur.
EOs are part of the broader category of motivating operations, which includes both establishing operations and abolishing operations (AOs). While EOs increase reinforcer value, AOs decrease it.
The Two Key Effects of an Establishing Operation
Every establishing operation produces two simultaneous effects:
- Value-altering effect: Temporarily increases the reinforcing effectiveness of a specific consequence
- Behavior-altering effect: Evokes behaviors that have historically accessed that reinforcer
These effects are momentary and reversible. Once the EO is removed or satisfied, the reinforcer returns to its baseline value.
Establishing Operation vs. Discriminative Stimulus (SD): The Critical Exam Discrimination
Many exam questions test your ability to distinguish between establishing operations and discriminative stimuli. While both are antecedents, they function differently.
- EOs alter reinforcer value: They change how much an individual wants or needs something
- SDs signal availability: They indicate that reinforcement is available for a specific behavior
For example, hunger (EO) makes food more valuable, while an open restaurant sign (SD) signals that food is available for purchase. Understanding this distinction is crucial for BCBA exam success.
Establishing Operations in Action: Worked ABA Examples
Let’s examine practical examples that demonstrate how establishing operations function in real-world settings. Each example includes a complete ABC analysis and hypothesized function.
Example 1: The Missed Snack & Elopement
A child misses their morning snack due to a schedule change. This creates an establishing operation for food as a potent reinforcer.
- Antecedent (EO): Missed morning snack (deprivation of food)
- Behavior: Elopement from classroom toward kitchen
- Consequence: Access to food items in kitchen
- Hypothesized Function: Access to tangible (food)
The missed snack momentarily increases the value of food, making escape behaviors that historically accessed food more likely.
Example 2: Social Deprivation and Attention-Maintained Behavior
A client spends two hours alone in their room without social interaction. This creates an EO for social attention.
- Antecedent (EO): Extended period without social interaction
- Behavior: Increased property destruction (throwing toys)
- Consequence: Caregiver enters room and provides attention
- Hypothesized Function: Access to social attention
The social deprivation increases the value of attention, evoking behaviors that have previously gained caregiver attention.
Example 3: Removing a Preferred Item as an EO
A therapist removes a tablet during a transition. This creates an EO for the tablet’s return.
- Antecedent (EO): Removal of preferred tablet
- Behavior: Manding ‘tablet please’ with increasing volume
- Consequence: Tablet returned contingent on appropriate request
- Hypothesized Function: Access to tangible (tablet)
Note that the EO is the removal/absence of the tablet, not the tablet itself. This distinction is critical for accurate analysis.
Establishing Operations on the BCBA Exam: What to Expect
Exam questions about establishing operations typically test your ability to identify EOs in scenarios, distinguish them from other antecedents, and predict their effects on behavior.
Common Exam Traps and How to Avoid Them
Watch for these common pitfalls:
- Confusing EO with SD: Remember EOs alter value, SDs signal availability
- Misidentifying the reinforcer: Ensure you identify the specific consequence whose value is altered
- Forgetting transient nature: EOs have momentary effects that can be reversed
- Overlooking deprivation states: Common EOs include sleep deprivation, food deprivation, and social isolation
These traps often appear in antecedent-focused questions where multiple variables are present.
Practice Applying the Concept: Sample Exam Prompts
Test your understanding with these vignettes:
Scenario 1: A student hasn’t had water access for 90 minutes during physical education. They begin asking repeatedly for water breaks. What is the EO?
Analysis: The EO is water deprivation, which increases the value of water as a reinforcer and evokes manding behavior.
Scenario 2: A client’s favorite staff member is on vacation for a week. The client engages in increased compliance with other staff when promised video calls with the preferred staff. What EO is at play?
Analysis: The EO is deprivation of interaction with preferred staff, increasing the value of that social contact.
Quick-Reference Checklist for Identifying Establishing Operations
Use this checklist when analyzing scenarios:
- Identify deprivation state: What is the individual lacking or needing?
- Determine value change: What consequence becomes more reinforcing?
- Check behavior correlation: Are behaviors that accessed that reinforcer increasing?
- Verify momentary effect: Would the effect disappear if the deprivation ended?
- Distinguish from SD: Is this altering value or signaling availability?
- Consider reversibility: Could an abolishing operation decrease this value?
This systematic approach helps ensure accurate identification of establishing operations in both clinical practice and exam scenarios.
Mastering establishing operations requires understanding their dual effects on reinforcer value and behavior. Practice identifying EOs in various contexts, and remember to distinguish them from discriminative stimuli and other antecedents.
