What involves the encoding of the meaning, including the meanings of words?

Semantic encoding is the process of encoding the meaning of information rather than just its superficial features. It focuses on understanding and interpreting the significance of words and concepts, allowing for a deeper processing of the information. This type of encoding is essential for forming connections and integrating new knowledge with existing knowledge, thereby enhancing memory retention. When individuals encode information semantically, they tend to remember it better because they attribute meaning to it, often associating it with their own experiences or knowledge.

Other methods of encoding, such as acoustic and visual encoding, deal with sounds and images, respectively, but do not necessarily engage with the meanings of the information being processed. Mnemonics involve techniques to aid memory retention but are not a method of encoding meaning in themselves. Thus, semantic encoding is specifically tied to understanding meanings, making it the most appropriate answer.
