Final answer:
Three observations supporting the Speech Learning Model include the perceptual reorganization in infancy, cultural immersion's impact on language learning, and the effectiveness of multimodal language teaching methods.
Step-by-step explanation:
There are several observations that support the Speech Learning Model, a theory that addresses how languages are acquired and processed:
- Perceptual Reorganization in Infancy: Research by Werker and Tees (1984) shows that infants undergo a perceptual reorganization during their first year, enabling them to distinguish sounds of any language. This suggests that language acquisition is influenced by exposure to language during critical periods in development.
- Cultural Immersion and Language Learning: Observations indicate that immersion in the culture associated with a language significantly boosts language acquisition. This supports the model's perspective that societal and environmental factors play a role in the mastery of a new language.
- Multimodal Language Teaching: Studies suggest that teaching sign language along with spoken language, as revealed in the case of parents using both with their children, may provide cognitive reinforcement that aids in language recall, aligning with the Speech Learning Model's proposition of the integration of various language modalities.
These observations highlight the complexities of language learning as an interplay between innate capacities and environmental influences, providing concrete evidence for the Speech Learning Model.
