Question

Quizplus · Accepted Answer

The influence of biological factors on speech development can explain why some sounds are commonly learned at the same age across cultures, as certain motor and cognitive abilities involved in producing speech sounds develop at predictable rates. It does not necessarily explain how languages developed or are similar across cultures, and while it may affect the rate of child speech development, that is not the main focus of the statement.
