Merriam Webster's

noun Date: 15th century 1. the process of habituating ; the state of being habituated 2. a. tolerance to the effects of a drug acquired through continued use b. psychological dependence on a drug after a period of use compare addiction 3. decrease in responsiveness upon repeated exposure to a stimulus

Britannica Concise

Reduction of an animal's behavioral response to a stimulus, as a result of a lack of reinforcement during continual exposure to the stimulus. Habituation is usually considered a form of learning in which behaviors not needed are eliminated. It may be separated from most other forms of decreased response on the basis of permanence; the habituated animal either does not resume its earlier reaction to the stimulus after a period of no stimulus, or, if the normal action is resumed on reexposure to the stimulus, it wanes more quickly than before. Vital responses (e.g., flight from a predator) cannot be truly habituated.

Webster's 1913 Dictionary

Habituation Ha*bit`u*a"tion, n. [Cf. F. habituation.] The act of habituating, or accustoming; the state of being habituated.
