Miniature language learning has been widely used to study the causality of language universals. However, factors that have been shown to affect language acquisition in other paradigms are understudied in miniature language learning, which calls into question results that claim to uncover universal biases. In this dissertation, I ask how the…

The tendency for negation to appear early in the sentence, dubbed the "Neg-First principle" by Horn (1989:452), has been observed in the domains of typology, language contact, and language acquisition. Based on evidence from these fields, scholars have speculated about the source and universality of Neg-First biases affecting language…

The present study investigates this notion in data collected from 15 observational studies of 40 L2 learners who acquired the L2 naturally, that is, they were not taught the language in any formal ways. Interpretation…
