In psychology, maturity is the ability to respond to the environment in an appropriate manner. This response is generally learned rather than instinctive . Maturity also encompasses being aware of the correct time and place to behave and knowing when to act, according to the circumstances and the culture of the society one lives in. Adult development and maturity theories include the purpose in life concept, in which maturity emphasizes a clear comprehension of life's purpose, directedness, and intentionality, which contributes to the feeling that life is meaningful.
