Final Answer:
At first a child uses a word such as mooi to refer to the moon. Then she uses the word to refer to round objects in general. This is an example of Overextension. Thus option 1 is correct.
Step-by-step explanation:
The given scenario aligns with the concept of overextension in language development. Overextension occurs when a child uses a specific word to refer to a broader range of objects or concepts than it conventionally represents. In this case, the child initially uses the word "mooi" to specifically refer to the moon but later extends its use to encompass round objects in general, which goes beyond the typical scope of the word's meaning.
In language development, overextension is a phenomenon observed in children's early vocabulary acquisition. It involves the expansion of a word's meaning to cover a wider range of referents than its conventional usage. For instance, when a child initially uses "mooi" to denote the moon but subsequently applies it to describe round objects beyond just the moon, it showcases the process of overextension. This behavior reflects the child's attempt to generalize the word's meaning based on shared characteristics (such as roundness) rather than strictly adhering to its original, specific reference.
Understanding overextension in language development involves recognizing a child's inclination to generalize words beyond their original contexts. In this scenario, the child's progression from using "mooi" solely for the moon to applying it to all round objects demonstrates an overextended use of the word. This developmental phase reflects the child's attempt to grasp broader concepts by associating common characteristics with specific words, showcasing the expansion and abstraction of language in early stages of learning. Thus option 1 is correct.
