The gill-withdraw reflex in the aplysia (sea-slug) decreases in intensity with successive presentations of a weak stimulus. this is an example of Non - Associative learning.
A process is when an organism's behavior toward a given stimulus evolves over time without any obvious linkage with consequences or other stimuli that might trigger such change.
The foundation of non-associative learning is therefore frequency. Sensitization and habituation are the two primary types of nonassociative learning. Comparative learning is an alternative.
Animals of all kinds, including protozoans and primates, can learn, or alter their behavior in response to experience.
A broad division between associative and non-associative learning processes can be made.
Non-associative learning happens in response to a single stimulus without reinforcement, whereas associative learning involves the association of two formerly unrelated stimuli with reinforcement.
It's debatable and not entirely clear how to distinguish between these two main learning types.
