In psychology, "habituation" is often seen as a simple form of learning. Technically, this is formed through repeated exposure to a stimulant so that the tendency to respond to it declines due to mental numbness. So, when habituation occurs, the mind is numbed towards a particular event, thus forming a habit.

Not only is habituation important, but it is also a very useful adaptative mechanism as it preserves the responses toward new events in the environment. When you notice something new, you first assess if the stimulus is harmful to you, whether it should be allowed to stay in your living environment and whether you should change your existing mental functions by way of time and attention. If the behaviour can be changed, then it is not a habit. If you often do something and this action has stopped causing a cycle of stimulation in your mind after a certain period of time, then this shows that the event has become a part of your environment and you have formed a habit. Your deeper consciousness will not pay it any attention. Hence, psychologists tend to use the theory of habituation to research human communication and the mental processes behind a person's behaviour and psychology. Alongside this, many psychologists also use this theory to study the minds of babies using various methods.

Classical conditioning occurs through the stimulation of the cerebral cortex. Stimulus is a term that refers to events, smells, sounds and visions in the environment. It is also a condition of learning through an unconditional response. For example, habitual responses toward a stimulus is seen when a person uses a rod to hit you. You yell out in pain. The rod is an unconditioned stimulus that brings about your cry, an unconditioned response. The unconditioned stimulus causes you to develop an unconditioned and natural psychological response. Thus, the conditioned stimulus is the true cause of the psychological response.

The key concept of psychology is that anything that can cause a change in your mental process is influenced by strengthened conditioned stimulus. Your responses are gradually reduced through repeated action (Extinction) day after day. As a result of this gradual mental reduction, once a spontaneous recovery is formed, this is habituation.
