This law posits that complex ideas or experiences composed of multiple simpler components can create associations that are more robust than those formed by isolated elements.

Bain's work expanded upon the existing laws of association, particularly emphasizing how combined experiences can affect the learning process and retention of information. His recognition of the importance of these compound ideas highlights the intricacies of human cognition, showing that our thoughts and memories are often interrelated rather than isolated snippets of information.

In contrast, the other options such as the Law of Frequency, Law of Vividness, and Law of Contiguity exist as foundational concepts established by earlier psychologists like David Hume and James Mill. They focus on different aspects of associative learning but do not capture the complexity that Bain introduced with the concept of compound association. The Law of Frequency relates to how often an idea occurs, the Law of Vividness pertains to the memorability of an experience, and the Law of Contiguity concerns the association of ideas that occur close together in time or space. While these are relevant in the context of associations, Bain's addition emphasizes
