"For example, when you enter a bakery, you are aware of the smell of the bread. After some time, you habituate, or become accustomed to, the aroma. Similarly, when you jump into a pool, you are at first aware of the cold water, but then you "get used to it." These are all cases of habituation, in which the repeated stimulation of the sensory receptors causes the receptors to fire less often, weakening the experience of the sensation."
"Habituation may also benefit behavior in other, less obvious ways. It can occur in response to dangerous stimuli, which are far from irrelevant. According to Ardiel et al. (2017), habituation occurs in response to dangerous stimuli to spur a new, more effective response toward them: "...habituation to a noxious stimulus might not just represent a decrease in the original response, but a shift from the original ineffective response to a different response that m"
Learning is a change in behavior that results from experience. Habituation weakens a response when the same stimulus is presented repeatedly. Repeated stimulation of sensory receptors causes them to fire less often, reducing the subjective intensity of sensations. Habituation examples include becoming accustomed to bakery aromas or to cold pool water. When a habituated stimulus is removed, the response can recover partially or fully, a phenomenon called spontaneous recovery. Habituation can free limited neuronal resources by allowing organisms to ignore irrelevant stimuli. Habituation can also occur to dangerous stimuli, enabling a shift from an ineffective original response to a different, more effective response.
