What are problems with Rescorla-Wagner's model?

The Rescorla-Wagner model, while influential in understanding classical conditioning, has several limitations. It does not account for the influence of cognitive processes, such as expectation or attention, which can affect learning. Additionally, the model struggles to explain phenomena like blocking, where prior conditioning prevents the learning of a new association, and it fails to accommodate the complexities of real-world learning, such as the role of context and biological constraints. Lastly, its reliance on a linear mathematical approach oversimplifies the dynamic nature of associative learning.
