What is an example of lexical priming?

The correct choice exemplifies lexical priming because it involves the activation of a person's understanding of a new word due to prior exposure to related words. Lexical priming refers to the phenomenon where the exposure to certain words makes related words more accessible in an individual's mind. This can occur through contextual clues or semantic associations—when someone learns or encounters a new word, they draw upon their knowledge of similar words or concepts they've previously encountered, which facilitates comprehension and usage.

In contrast, the other options do not directly represent the mechanism of lexical priming. For instance, recalling a math formula after a lecture pertains to memory retrieval rather than the activation of word associations. Analyzing a poem influenced by previous literature would involve broader cognitive processes like critical thinking and synthesis of ideas, and memorizing vocabulary through repetition emphasizes memorization techniques rather than the associative nature of language processing that characterizes lexical priming. Thus, the choice related to understanding a new word due to exposure to related words accurately captures the essence of lexical priming.
