The goal of this paper is to tease apart two approaches to the source of children's consistent scope assignment in negative sentences containing logical connectives: the Semantic Subset Principle and the Semantic Subset Maxim. Previous developmental work has observed that four- to six-year-old children across languages have difficulty with…

In a body of empirical research, it has been observed that young children from across different linguistic communities adhered to a particular type of nonadult interpretation of disjunction: They appear to interpret disjunction conjunctively. Through three experiments with Japanese-speaking preschoolers, we investigate the source of this nonadult…

Relatively late mastery of scalar implicatures has been suggested to correlate with children's immature processing capacities, such as their limited working memory. Yet, many studies that tested for a link between children's working memory and their computation of scalar implicatures have failed to find any correlation. One possible reason is that…

This study reports findings from two truth value judgment experiments to address two research questions on Mandarin: (i) whether children and adults have the knowledge of the structural constraint Principle C in their pronoun resolution; and (ii) whether adults and children show the prohibition effect of the cyclic-c-command constraint or the QR…

The "wanna" facts are a classic Poverty of Stimulus (PoS) problem: "Wanna" is grammatical in certain contexts ("Who do you want PRO to play with?") but not others ("Who do you want who[strikethrough] to play with you?"). On a standard analysis, "contraction" to "wanna" is blocked by some…

Italian relative clauses like "Il bambino che bacia la mamma" 'the child that kisses the mom' are ambiguous between a subject reading and an object reading with postverbal subject. However, the latter is scarcely accessible for word order and theory-internal considerations. This study aims at investigating the role of semantic…

Deaf students often differ from their hearing peers in written language development. Providing developmentally appropriate instruction is ideal, yet current methods of writing assessment do not provide teachers with sufficient information regarding the written language (i.e., syntactic) development of deaf students. In this research, we use a…

This study investigates the knowledge of unaccusativity in Japanese native, heritage, and second/foreign language speakers with respect to licensing of floating numeral quantifiers (FNQs) by unaccusative and unergative subjects (the "FNQ diagnostic"). Two acceptability judgment experiments were conducted to examine (i) whether and how…

This article presents a study of preschool-aged children's knowledge of the semantics of the negative polarity item (NPI) "any". NPIs like "any" differ in distribution from non-polarity-sensitive indefinites like "a": "Any" is restricted to downward-entailing linguistic environments (Fauconnier 1975, 1979;…

This study investigates the challenges faced by Arab adult learners of English as a foreign language (EFL) in acquiring English restrictive relative clauses (RRCs), as well as the factors that affect the process of acquisition. This issue has received considerable attention in second language (L2) research. The present study discusses the…
