Final answer:
Semantic code describes the meaning of content on a page. Semantic encoding is how words and their meanings are processed, which Bousfield's experiment in 1935 demonstrated by having subjects recall words categorized by meaning.
Step-by-step explanation:
Semantic code describes the meaning of content on a page, regardless of the style or appearance of that content. Semantic encoding, which refers to the encoding of words and their meanings, plays a crucial role in how we understand and categorize information. An example of this process was demonstrated by William Bousfield in 1935 with an experiment in which individuals were more likely to remember words when they were associated with similar meanings, showing they paid attention to the semantics as they learned.
