The correct answer is B. Habituation
Step-by-step explanation:
The term "habituation" refers to a type of learning in which a stimulus is presented multiple times and this decreases the response the individual has towards the stimulus. Habituation commonly occurs if the stimulus has not any negative or positive consequence and therefore the interest of the individual in the stimulus decreases over time.
For example, if a loud noise (stimulus) is presented this leads to the individual being alert or scare (response) but if this is presented multiple times with no consequence this response reduces or even disappears. Habituation is also the phenomenon in babies that pay less attention when a stimulus is presented multiple times because the stimulus does not cause the same initial response as the individual is familiarized with it.
