Shin and Mill (2021) propose four steps children go through when learning "variable form use." Although I applaud Shin and Miller's focus on morphosyntactic variation, their accrual of evidence is post hoc and selective. Fortunately, Shin and Miller recognize this and encourage tests of their ideas. In support of their work, I share data…

This study investigated the developmental trajectories of three perceptual domains related to regional dialect competence: the linguistic domain, tested through an intelligibility in noise task; the objective indexical domain, tested through locality judgments and a free classification task; and the subjective indexical domain, tested through…

Efficient language use involves the capacity to flexibly adjust to varied pronunciations of words. Although children can contend with some accent variability before their second birthday, it is currently unclear when and how this ability reaches its mature state. In a series of five experiments, we examine the developmental trajectory of toddlers'…
