Description: Habituation is a psychological and biological process by which an organism becomes accustomed to a specific stimulus, decreasing its response to it over time. This phenomenon is observed in various species, from invertebrates to mammals, and is fundamental for adaptation to the environment. Habituation allows living beings to ignore stimuli that are irrelevant or do not pose a threat, helping them focus their attention on more important signals. This process is based on neural plasticity, where synaptic connections adjust in response to experience. As a stimulus is repeatedly presented, the organism’s response becomes less intense, indicating that it has learned not to react to it. Habituation is an essential mechanism for survival, as it enables animals and humans to filter information and prioritize cognitive resources to face more significant challenges in their environment. This process can influence sensory perception, emotional responses, and social behaviors, affecting how individuals interact with their surroundings and with other living beings.
