What is Deprivation in ABA Therapy?
In Applied Behavior Analysis (ABA) therapy, deprivation refers to the state in which an individual has not had access to a particular reinforcer for a period of time, increasing the value of that reinforcer.
This principle is part of a broader concept known as motivating operations (MOs), which influence the effectiveness of a consequence (like reinforcement) on behavior. For example, if a child has not had access to their favorite toy for a few hours, their motivation to earn or request that toy is typically higher.
Deprivation increases the likelihood that a behavior aimed at accessing the reinforcer will occur. Understanding and ethically applying deprivation helps ABA professionals:
- Encourage skill-building and positive behaviors
- Ensure reinforcers remain effective over time
- Individualize treatment based on preferences and needs
It is important to differentiate deprivation from neglect or withholding necessary items inappropriately. Ethical guidelines set by the Behavior Analyst Certification Board (BACB) ensure reinforcers are used responsibly and that a child’s dignity and well-being are protected at all times.

Examples of Deprivation in ABA Therapy
Example 1: Food as a Reinforcer
If a child is slightly hungry before a session (within safe and ethical boundaries), small food items like crackers may be more effective as reinforcers. The temporary deprivation increases the motivational value of the food.
Example 2: Preferred Activities
If a child hasn’t had tablet time all morning, access to a tablet may be a powerful reinforcer during therapy. A behavior technician may prompt the child to complete a task, then allow brief access to the tablet as reinforcement.
Example 3: Social Interaction
If a child has not had social engagement for a short period, praise or high-fives may be more effective. Deprivation of social attention can temporarily raise its value, making it more reinforcing.

FAQs About Deprivation in ABA Therapy
How does deprivation increase the effectiveness of a reinforcer?
Deprivation heightens an individual’s desire for a specific item or activity, making the associated reinforcer more powerful. This helps ABA behavior technicians motivate and reinforce skill acquisition more effectively.
Is deprivation the same as punishment?
No. Deprivation is not a punishment. It is a strategy used to increase motivation by limiting access to a reinforcer temporarily. It must always be used ethically, with the individual’s well-being prioritized.
How long should deprivation last in ABA therapy?
The length of deprivation depends on the individual and the reinforcer. It should never involve withholding basic needs. ABA professionals carefully balance deprivation to maintain the effectiveness of a reinforcer without causing distress.
What is the difference between deprivation and satiation?
Deprivation increases the value of a reinforcer due to lack of access. Satiation, on the other hand, decreases value because the individual has had too much of it. Both are key concepts in managing motivating operations.
Can parents use deprivation strategies at home?
Yes, when done ethically and in coordination with an ABA professional. For instance, limiting access to a favorite toy before practicing communication skills can increase motivation to request it.
