I am interested in what knowledge we have regarding the process by which a young child acquiring French as a first language learns to choose correctly between the masculine and feminine forms of adjectives when describing themselves. If, for instance, a young girl grows up in a French-speaking household where everyone else is male, is her learning to describe herself using feminine forms delayed for lack of examples of female self-descriptive speech to copy and learn from?
Some subsidiary questions that come under the same umbrella:
Do children learn to make this m/f distinction sooner or later if the masculine and feminine forms sound very different (e.g. "beau" and "belle") compared to more similar sounding forms such as "blond" and "blonde"?
How and when do children learn that m/f forms that sound very different from each other (again taking the example of beau/belle) are forms of the same adjective?
Is how and when children learn to make this distinction to describe themselves closely related - or unrelated - to how and when they learn to use the appropriate masculine or feminine forms of articles, adjectives and so on when speaking about common nouns? Are grammatical gender and natural gender often confused with each other by children as they learn to speak French as a first language?
How and when is learning to use the correct forms of adjectives to describe themselves related to the process by which children learn to use the appropriate masculine or feminine pronoun to refer to themselves?
Or, indeed, the process by which children learn to identify themselves as male or female?
How do other languages with distinct female and male forms of speech compare to French in this regard? (While I am aware that English comes into this category for some pronouns and other words, I am primarily interested in languages that make as much or more use of gender-specific forms as French does.)
