The word frequency effect refers to the phenomenon where more frequently encountered words are processed more quickly and easily than less frequent words, suggesting that the familiarity of a word influences its recognition and understanding. This effect is heavily impacted by the meaning of words, as words that are meaningful and relevant to an individual's experience tend to be encountered more often in various contexts.

In contrast, the word length effect relates to the observation that shorter words are generally easier to remember and recall than longer words, a trait that primarily involves memory and cognitive load rather than the semantic meaning of the words themselves. Similarly, contextual usage is influenced directly by meaning, as the surrounding words and situations define how a word should be interpreted. Sentence structure also interacts with meaning since the arrangement of words contributes significantly to the overall comprehension of communication.

Thus, the word frequency effect is not the correct answer as it is indeed influenced by meaning in the context of how often we encounter and therefore understand words based on their semantics. Finding the choice that specifically does not hinge on the semantic interpretation points to the word length effect, which focuses more on the physical attributes of words rather than their meanings.
