It allows us to function in environments where we are often inundated with sensory experiences and information. Rather than being overwhelmed by all of the things that clamor for our attention, habituation allows us to pay less attention to certain elements so that we can better focus on others.

What is the purpose of habituation?

Nonassociative Learning: Habituation

In habituation, behavioral responsiveness to a test stimulus decreases with repetition. It has the important function of enabling us to ignore repetitive, irrelevant stimuli so that we can remain responsive to sporadic stimuli, typically of greater significance.

Why is habituation beneficial for survival?

Habituation is important in filtering the large amounts of information received from the surrounding environment. By habituating to less important signals, an animal can focus its attention on the most important features of its environment.
