Language development, linguistic input, and linguistic racism

Area of Science:

• Linguistics
• Developmental Psychology
• Neuroscience

Background:

• Child language acquisition is a natural developmental process.
• Current research often assumes "quality" linguistic input is essential for development.
• "Quality" is a subjective judgment, not an objective linguistic feature.

Purpose of the Study:

• To challenge the empirical falsehood that "quality" linguistic input is necessary for language development.
• To identify and critique the concept of "quality" in linguistic input.
• To explore the role of linguistic racism in the study of language acquisition.

Main Methods:

• Critical analysis of existing research on language development.
• Examination of the concept of "quality" within linguistic theory.
• Exploration of the intersection of race, language, and scientific methodology.

Main Results:

• The concept of "quality" linguistic input is a subjective value judgment, not a scientific construct.
• The insistence on "quality" input reflects a deficit perspective, particularly towards racialized children.
• This perspective constitutes linguistic racism, impeding accurate understanding of language development.

Conclusions:

• Rethinking the necessity of "quality" input is crucial for advancing the science of language acquisition.
• Addressing linguistic racism is essential for unbiased and accurate research in developmental linguistics.
• A more inclusive and accurate understanding of language development requires abandoning subjective "quality" judgments.
