Demonstrative words are one of the most important ways of establishing reference in conversation. This work describes Spanish-speaking children's demonstrative production between ages 2 to 10 using data from the CHILDES corpora. Results indicate that children feature all demonstratives in their lexicon -- however, the distal term is scarce…

Quantifier spreading (Q-spreading), children's incorrect falsification of a universally-quantified sentence based on an 'extra-object' picture, may persist beyond childhood, and children adhere to Q-spreading without changing responses throughout testing. We examined the error patterns across wider age groups (aged 4-79) with a picture-sentence…

The acquisition of quantifiers is a central topic in cognitive science. The present study investigated the emergence, frequency, and non-target-like production of the universal quantifiers "all," "every," and "each" in child English from a linguistic perspective, based on the data from longitudinal naturalistic…

This study addresses the question of whether gender agreement is impaired in SLI German. Article production and gender marking on articles were examined in three groups of German-speaking children: 10 children with Specific Language Impairment (SLI), 10 age-matched typically developing (TD) children, and 10 TD children who were on average two…

This article explores the role of the reportative BIN in Yucatec Maya language acquisition and socialization among children aged 4 years and above, focusing on their interactions during pretend play. Building upon prior research on caregivers' strategic use of BIN, the study aims to elucidate the nuanced meanings and functions of the reportative…

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…

Child language acquisition research has provided ample evidence of lexical frequency effects. This corpus-based analysis introduces a novel frequency measure shown to significantly constrain adult language variation, but heretofore unexplored in child language acquisition research. Among adults, frequent occurrence of a form in a particular…

This paper investigates the interpretation that Italian-speaking children and adults assign to negative sentences with disjunction and negative sentences with conjunction. The aim of the study was to determine whether children and adults assign the same interpretation to these types of sentences. The Semantic Subset Principle (SSP) (Crain et al.,…

This study examined the developmental trajectories of Arabic grammatical number in Arabic-English bilingual children. The samples consisted of 80 individuals (40 monolingual children residing in Jordan and 40 bilingual children residing in the USA), aged between 5 and 9 years. Data was collected through two tasks involving picture able objects and…

We examine whether German children attach an adultlike relevance to the pragmatic category of polarity contrast (e.g., "In my picture the child IS eating the candies" following after "In my picture the child is not eating the candies") with linguistic expressions (i.e., the affirmative particles…

We report three studies (one corpus, two experimental) that investigated the acquisition of relative clauses (RCs) in Finnish-speaking children. Study 1 found that Finnish children's naturalistic exposure to RCs predominantly consists of non-subject relatives (i.e. oblique, object) which typically have inanimate head nouns. Study 2 tested…

This study investigated how Turkish-speaking children and adults interpret negative sentences with disjunction (English "or") and ones with conjunction (English "and"). The goal was to see whether Turkish-speaking children and adults assigned the same interpretation to both kinds of sentences and, if not, to determine the…

Constraints on linguistic variation are consistent across adult speakers, yielding probabilistic and systematic patterns. Yet, little is known about the development of such patterns during childhood. This study investigates Spanish subject pronoun expression in naturalistic data from 154 monolingual children in Mexico, divided into four age…

This paper investigates the development of discourse referencing in spoken Cantonese of fifteen deaf/hard-of-hearing children studying in a sign bilingual and co-enrolment education programme in a mainstream setting in Hong Kong. A comparison of their elicited narratives with those of the hearing children and adults shows that, despite a delay in…

The interpretation of floating quantifiers in Japanese requires knowledge of hierarchical phrase structure. However, the input to children is insufficient or even misleading, as our analysis indicates. This presents an intriguing question on learnability: do children interpret floating quantifiers based on a structure-dependent rule which is not…
