Final answer:
Alison's ability to sleep through the banging of a branch suggests Non-associative learning, as she's become habituated to the noise and does not respond as strongly to it over time.
Step-by-step explanation:
If Alison sleeps through the banging of a branch on her window, the type of learning exhibited is Non-associative learning. Non-associative learning is a type of learning in which an organism is repeatedly exposed to one type of stimulus and starts to become accustomed to it, thereby responding less over time. This is in contrast to associative learning, which involves forming connections between stimuli and behaviors, and includes types such as classical and operant conditioning. In Alison's case, she has likely become habituated to the noise, which is why she continues to sleep without being disturbed by the sound.
