What is the most likely etiology of Sophia's suspected language disorder?

The most likely etiology of Sophia's suspected language disorder being a developmental disorder is grounded in the understanding of language acquisition and the typical trajectories of language development in children. Developmental disorders often manifest during childhood and can lead to noticeable delays or differences in language skills as children grow and learn to communicate.

In contrast, a psychogenic disorder typically arises from psychological factors rather than physiological ones; while these can influence language use, they are less common as the primary cause of language disorders. An auditory processing disorder specifically relates to how the brain processes auditory information, which would present differently than a language disorder stemming from developmental issues. An acquired disorder refers to language deficits that occur following a specific event or injury, such as a stroke or traumatic brain injury, which would not typically be the case in a situation that suggests a longstanding issue like a developmental disorder.

Overall, developmental disorders represent a broader category that encompasses a variety of challenges in speech and language that arise during critical periods of language acquisition, making it the most fitting choice in this scenario.
