Which of the following does not directly contribute to articulatory disorders in children?

The correct answer indicates that oral hygiene practices do not directly contribute to articulatory disorders in children. While good oral hygiene is essential for preventing dental issues that can affect speech, it does not have a direct impact on the mechanics of articulation itself. Articulatory disorders primarily stem from factors that affect the ability to produce speech sounds correctly.

In contrast, phonological processes, speech-language delays, and neurological conditions directly relate to how children develop and produce speech. Phonological processes involve patterns that children may use in speech production, which can lead to misunderstandings in sound use. A speech-language delay can result in a child's difficulty in producing sounds within the expected age range, affecting their articulation. Neurological conditions such as cerebral palsy or apraxia can significantly inhibit the coordination and neural mechanisms necessary for clear speech production. Therefore, the other choices are more closely linked to the causes of articulatory disorders.
