Professor Dore maintains that language develops through the interplay of genetically determined factors and environmental influences that shape how language is learned. Professor Dore supports the

A-Learning theory approach to language development
B-Nativist approach to language development
C-Interaction approach to language development
D-Linguistic-relativity hypothesis

C-Interaction approach to language development

C-Interaction approach to language development

The answer is C-Interaction approach to language development.

In order to reach this answer, we can examine the given statement and match it to the different options provided.

The statement mentions that language develops through the interplay of genetically determined factors and environmental influences that shape how language is learned.

The Learning theory approach (option A) emphasizes that language is learned through general processes of learning, such as conditioning and reinforcement. However, the statement mentions both genetically determined factors and environmental influences, which suggests a broader approach than just learning theory.

The Nativist approach (option B) suggests that language is primarily innate and independent of environmental influences. However, the statement specifically mentions the interplay of genetically determined factors and environmental influences, suggesting a more comprehensive approach.

The Interaction approach (option C) recognizes that language development is a result of both genetic factors and interaction with the environment. It highlights the importance of social interaction, cultural context, and cognitive development in language learning. This aligns with the statement and is therefore the most appropriate answer.

The Linguistic-relativity hypothesis (option D) states that the structure of a language influences the way its speakers perceive and think about the world. While this hypothesis is relevant to language development, it does not specifically address the interplay of genetically determined factors and environmental influence mentioned in the statement.

Therefore, the answer is C-Interaction approach to language development.
