Habituation refers to a gradual reduction in the strength of a response due to repetitive stimulation.

Explanation:

Habituation is the decrease in sensitivity to an external stimulus when it is repeated in the same way, that is, the response is less intense due to repetitive stimulation. Habituation can be considered the most primitive form of learning and it occurs at all levels of the organism, from the cellular to the psychological. At the level of the nervous system, it can be observed in simple reflexes such as perspiration, muscle contraction and in the activity of groups of neurons.
