Preschoolers: Adult-like use of "the"
Corpus analysis: children (1;0-3;11) use "the" at rates comparable to their mothers overall and across contexts, with minimal referential failure (Ying et al., 2024).
Human simulation paradigm: adults presented with conversation snippets are equally well at guessing determiners ("the" vs. "a") used by children (2;0-5;0) and mothers (Ying et al., 2024).
Conversational elicited production: even 3- to 4-year-olds are adult-like in producing "the"-expressions (Ying et al., under review)

Video corpus (in prep): What are the usage profiles like for toddlers’ first vs. later uses of “the”? Do their earliest output simply mimic or differ from their caregivers' input?
