A child learns a new word after only one exposure and applies it to related contexts; this illustrates which concept?

• A. Holophrase
• B. Habituation
• C. Overregularizations
• D. Fast Mapping

Answer: (D)

Fast mapping is the ability to learn a new word after only one exposure and then extend that label to related items or contexts. This means the child quickly forms a connection between a word and its meaning and can generalize it to other similar referents, which helps explain rapid vocabulary growth. For example, after hearing a caregiver call a new animal a name, the child may later use that same word for other animals in the same category. This differs from holophrase (one word standing in for a larger idea), habituation (getting bored with repeated exposure), and overregularizations (incorrectly applying grammar rules).
