According to the principles of operant conditioning, this phenomenon is due to property of extinction.
Operant conditioning which is also known as instrumental conditioning may be defined as a type of associative learning process which consists of awarding rewards or penalties based on behavioral aspects. It is also a method that is employed to facilitate such learning of behavioral aspects. Although both operant and classical conditioning have actions that are influenced by their surroundings and are in some way similar, though they are different fundamentally. In the case of operant conditioning, environmental effects are also considered to dictate behavior. A toddler may learn, for instance, how to open a box to retrieve the candy inside or how to keep their hands away from hot things. In operant terminology, these examples are termed as "discriminative stimuli." It is often stated by experts that operational behavior is "voluntary". Operant responses are those that are controlled by the organism.
