Final answer:
It is false that reducing the complexity of a mother's utterances aids language intervention; environmental exposure and rich interaction are key to language development. The correct option is b.
Step-by-step explanation:
It is false that one approach to language intervention involves shortening the length of mother's utterances to children in order to reduce complexity. This notion might stem from the popular concept of "motherese," which comprises simplified language and exaggerated speech patterns used by caregivers when talking to babies.
However, language intervention strategies and child language acquisition theories indicate that variety and richness of linguistic input are crucial for language development. Cross-cultural studies suggest that exposure to diverse linguistic input through social interaction in the environment contributes significantly.
Therefore, rather than simplifying language, fostering rich and meaningful interactions is often encouraged.
It's important to consider that language acquisition is influenced by both environmental factors and an innate capacity to learn, as per the theories of Chomsky and Skinner. Providing children with diverse and meaningful linguistic experiences is key for optimal language development, rather than exclusively relying on simplified speech.
Hence, Option b is correct.
