The main difference between primary and secondary reinforcers is that primary reinforcer is biological stimulus causing involuntary reflex while secondary reinforcer is conditioned stimulus causing learned behavior.

Let’s explore the psychology behind and how parents and teachers can make good use of them.
What is Primary Reinforcement
Primary reinforcement is a naturally occurring reaction to a stimulus. The response is innate and doesn’t require intricate learning. Primary reinforcement is a reflex that an organism performs automatically whenever the corresponding stimulus is presented1.
For instance, your mouth waters when you detect the delicious smell of your favorite food. It’s a natural reflex, and you don’t need to learn to drool.
Most primary reinforcements are the result of evolution to ensure a species’ survival. Salivation in anticipation of food intake helps the body optimize digestion2.
A Primary Reinforcer is a stimulus that is biologically important to an organism, such as food, water, sleep, shelter, safety, pleasure, and sex. It leads to an involuntary response, such as recoiling, drooling, and trembling. In Classical conditioning theories, a primary reinforcer is also called unconditioned reinforcer or unconditioned stimulus (UCS).
Although primary reinforcers are intrinsic drives that are naturally occurring, they may impact individuals differently depending on genetics and their experiences.
For example, some people can tolerate a higher temperature than others. When they touch something hot, their withdrawal reflex may not be triggered unless the object is scalding. The ability to withstand higher temperatures may be inborn, or perhaps due to repeated encountering in the past, i.e., an individual may be trained by experience to react differently to a primary reinforcer.
When you touch a scorching iron, your hand recoils automatically to prevent burning. This reflex is a protective mechanism. The scalding touch is the primary reinforcer that reinforces automatic hand withdrawal.
When a baby is hungry, she cries. Her caretaker then feeds her to satisfy her hunger. This response is a survival reflex that doesn’t require learning. In this case, hunger is the primary reinforcer that reinforces the crying.
Secondary Reinforcement and Secondary Reinforcer
Secondary reinforcement is repeatedly pairing a neutral stimulus with a primary reinforcer so that the neutral stimulus can induce the same response as the primary one. Secondary reinforcement turns a neutral stimulus into a conditioned stimulus, also known as a secondary reinforcer.
So, what is the difference between primary and secondary reinforcers?
While a primary reinforcer is innate, a secondary reinforcer is a stimulus that becomes reinforcing after being paired with a primary reinforcer, such as praise, treats, or money. Responding to the secondary reinforcer is a learned behavior, not a born reflex.
Effectiveness and Durability
Primary reinforcements are effective because they are biological and play a fundamental role in survival. They are often more effective than secondary reinforcers.
A hungry worker who is promised food for finishing the work is more intrinsically motivated to do so than someone working for free movie tickets.
Because primary reinforcements are essential for survival, they are hard to unlearn.
For example, it takes strong willpower or training not to scream when a heavy stone drops on your feet.
