Final answer:
Habituation is the decrease in response to repeated presentation of the same stimulus. It is a simple form of learning where an animal stops responding to a stimulus after repeated exposure.
Step-by-step explanation:
The decrease in response to repeated presentation of the same stimulus is referred to as habituation. Habituation is a simple form of learning in which an animal stops responding to a stimulus after a period of repeated exposure. It is a non-associative learning process, as the stimulus is not associated with any punishment or reward. For example, prairie dogs become habituated to the sound of human footsteps when no harm is associated with it, and they no longer respond with an alarm call to these sounds.
