What role do concrete nouns play in memory enhancement according to Pavio?

Concrete nouns significantly contribute to memory enhancement by facilitating the pairing of words through their vivid and tangible nature. According to Allan Paivio's dual coding theory, concrete nouns evoke mental images that are easier to visualize and remember compared to abstract concepts. This dual coding—where information is processed both verbally and visually—creates stronger memory traces in the brain.

When concrete nouns are used, they enable individuals to form associations that can leverage both visual imagery and verbal encoding, enhancing recall. For instance, the word ‘apple’ triggers a clear, vivid image that can link to various related concepts or experiences, making recall more effective. This process is particularly useful in educational settings where enhancing memory is crucial, as it allows learners to create stronger mental connections between spoken or written words and their meanings or associations.

In contrast, while other options may seem plausible, they do not capture the essence of how concrete nouns enhance memory as effectively as the ability to facilitate word pairings through visualization and mental imagery.
