The most recent studies on the acquisition of evidentiality, be it morphologically or syntactically encoded, have argued that the comprehension lag detected is due to factors having to do with others' authority or mental perspective, where "others" stands for other individuals involved in the experiment in various manners (e.g., the…

In English, the sentence "Mary didn't eat pizza or sushi" is assigned the "neither interpretation" (both disjuncts must be false). In Mandarin Chinese, the equivalent sentence is assigned the at least one interpretation (at least one disjunct must be false). The cross-linguistic variation in the interpretation of negative…

The two possible positions for "wh"-words (i.e., in situ or preposed) represent a long-standing area of research in French. The present study reports on statistical analyses of a new seminaturalistic corpus of child L1 French. The distribution of the "wh"-words is examined in relation to a new verb tripartition: Free…

Children have difficulty comprehending novel verbs in the double object dative (e.g., "Fred blicked the dog a stick") as compared to the prepositional dative (e.g., "Fred blicked a stick to the dog"). We explored this pattern with 3 and 4 year olds (N = 60). In Experiment 1, we replicated the documented difficulty with the…

An evaluation measure (EM) guides a learner's choice of grammar when more than one is compatible with available input. EM must be universal, so children receiving comparable input acquire comparable grammars. It must favor the choices children actually make. The theoretical shift from rule-based grammars to principles-and-parameter-based grammars…

Recent ERP research with adults has shown that the online processing of subject-verb (S-V) agreement violations is mediated by the relative perceptual salience of the violation (Dube et al. 2016). These findings corroborate infant perception research, which has also shown that perceptual salience influences infants' sensitivity to grammatical…

This study examines the "ba" and "bei" constructions in Mandarin using data from the Tong corpus, a new multimedia longitudinal child language corpus. A unified aspectual account of the two constructions is proposed: both require telic predicates, and should thus correlate with the perfective rather than imperfective aspect for…

We present a series of experiments investigating English-speaking children's comprehension of "it"-clefts and "wh"-pseudoclefts. Previous developmental work has found children to have asymmetric difficulties interpreting object clefts. We show that these difficulties disappear when clefts are presented in felicitous contexts,…

The phenomenon of regularization -- learners imposing systematicity on inconsistent variation in language input -- is complex. Studies show that children are more likely to regularize than adults, but adults will also regularize under certain circumstances. Exactly why we see the pattern of behaviour that we do is not well understood, however.…

This study investigates the interpretation of disjunction words (English or) in negative sentences by Turkish- and German-speaking children. Both children and adults were asked to judge Turkish/German sentences corresponding to the English sentence "This animal did not eat the carrot or the pepper." Children acquiring both languages…

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;…

To test between two recent accounts of the early stages in the acquisition of negation, we conducted an elicited production study with 25 children, between 2;05 and 3;04 (mean 2;11). The experimental study produced a robust set of negative sentences, with considerable individual variation. Although 13 of the child participants mainly produced…

The current study examined preschool children's ability to evaluate the entailment patterns yielded by sentences containing two downward entailing (DE) operators, "every" and "no." When "no" precedes "every," the entailment pattern typically licensed by "every" changes, but only if "no"…

In Study 1 we analyzed Italian child-directed-speech (CDS) and selected the three most frequent active transitive sentence frames used with overt subjects. In Study 2 we experimentally investigated how Italian-speaking children aged 2;6, 3;6, and 4;6 comprehended these orders with novel verbs when the cues of animacy, gender, and subject-verb…

We study the learnability problem concerning the dative alternations in English (Baker, 1979; Pinker, 1989). We consider how first language learners productively apply the double-object and to-dative constructions ("give the book to library"/"give the library the book"), while excluding negative exceptions ("donate the…
