Lisa is four years old and sleeps with her teddy bear every night. At a carnival, Lisa's father offers to win her a prize. He asks, 'Wouldn't you like that teddy bear?' Lisa frowns and says, 'But that's not teddy bear. Teddy bear is at home.' Lisa's misunderstanding is an example of which of the following?

Overextension involves using a word too broadly, applying it to objects or entities beyond its conventional meaning. For example, a child might call all furry animals "dog." In Lisa's case, she does not apply the term "teddy bear" broadly; instead, she limits it to her own teddy bear, so this choice does not fit.

Fast mapping describes the ability of children to quickly learn and remember new words after minimal exposure. While this process is critical in language acquisition, it does not relate to Lisa's misunderstanding of the term "teddy bear," making this choice irrelevant.

Overregularization refers to the application of regular grammatical rules to irregular cases, such as saying "goed" instead of "went." This concept pertains to verb conjugation and does not apply to Lisa's situation, where the issue is about noun categorization.

Holographic speech is characterized by a single word that conveys a complete thought, common in early language development. Lisa's response is not a single-word utterance but rather a misunderstanding of a term, thus making this choice incorrect.
