Final answer:
When a baby sucks more after being presented with a new sound in the high-amplitude sucking method, it can be inferred that the baby is habituated to the new sound.
Step-by-step explanation:
In the high-amplitude sucking method, when a baby sucks more after being presented with a new sound, it can be inferred that the baby is habituated to the new sound.
Habituation is a simple form of learning in which an animal stops responding to a stimulus after repeated exposure. In this case, the baby has become accustomed to the new sound and is no longer responding as strongly to it.
This is similar to how you may have habituated to the sound of a television in the background while reading a book.
