Habituation is a psychological process where an organism gradually reduces its response to a repeated stimulus over time. For example, if a loud noise occurs repeatedly, a person may initially startle but will eventually become less reactive to it. This process helps organisms focus on more important changes in their environment rather than being distracted by constant, unimportant stimuli. This phenomenon is observed in many species, including humans and animals. Habituation allows for energy conservation and better adaptation to surroundings. It is a fundamental aspect of learning and can be seen in various contexts, such as training pets or adjusting to new environments.
