What theories explain the origins of language development?

What will be an ideal response?

A good answer would include the following key points:
• The learning theory approach: the theory that language acquisition follows the basic laws of reinforcement and conditioning.
• The nativist approach: the theory that a genetically determined mechanism directs language development.
• The interactionist approach: the theory that suggests that language is produced through a combination of genetically determined predispositions and environmental circumstances.
