Current understanding of word-finding (WF) difficulties in children and their underlying language processing deficit is poor. Authors have proposed that different underlying deficits may result in different profiles. The current study aimed to better understand WF difficulties by identifying difficult tasks for children with WF difficulties and by…

"Wh"-words have been analysed as existential quantifiers (Chierchia in Logic in grammar: polarity, free choice, and intervention. Oxford University Press, Oxford, 2013; Fox, in Sauerland U, Stateva P (eds) Presupposition and implicature in compositional semantics (Palgrave studies in pragmatics, language and cognition). Palgrave…

Previous research has documented that children count spatiotemporally-distinct partial objects as if they were whole objects. This behavior extends beyond counting to inclusion of partial objects in assessment and comparisons of quantities. Multiple accounts of this performance have been proposed: children and adults differ qualitatively in their…

Scalar implicatures (SIs) lie at the interface between semantics and pragmatics, and therefore have evoked great interest for language acquisition research. Many acquisition studies show that young children know the literal semantics of scalar items (like "some", "might", "start" and "or") but have…

One of the fundamental questions in the field of language acquisition is a learnability problem, which considers how learners acquire certain aspects of language which are not directly provided in the input or whose referents are not readily observable. This dissertation investigates Japanese children's acquisition of various linguistic phenomena,…

Scholars of language development have long been challenged to understand the development of functional categories. Traditionally, it was assumed that children's language development initially relies on lexical elements, while functional elements become accessible only at later periods; and that it is lexical growth which bootstraps grammatical…

Children seem to be relatively delayed in their comprehension of the verbal "be"-passive in English, compared to their acquisition of other constructions of object-movement such as "wh"-questions and unaccusatives. Prior work has found that children's performance on these passives can be affected by the verb's lexical…

The organization of our knowledge about the world into an interconnected network of concepts linked by relations profoundly impacts many facets of cognition, including attention, memory retrieval, reasoning, and learning. It is therefore crucial to understand how organized semantic representations are acquired. The present experiment investigated…

Perturbations to the speech articulators induced by frequently using an interfering object during infancy (i.e., pacifier) might shape children's language experience and the building of conceptual representations. Seventy-one typically developing third graders performed a semantic categorization task with abstract, concrete and emotional words.…

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.,…

The comprehension of paired wh-questions is examined in child Mandarin, to compare the age of acquisition with that of children speaking European languages like English and German. In Study 1, participants were 734 Mandarin speakers aged 2;6-7;11, drawn from four regions of China. Results reveal a striking parallel between the acquisition of…

Mandarin classifiers are a complex system, but little is known about how Mandarin-speaking children manage to learn the system. Based on the extant literature, we explored potential factors influencing the comprehension and production of Mandarin shape classifiers, including classifier-based semantic categorization and errors pertaining to the…

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"…

This article investigates the acquisition of different types of clefts and of "be"-fragments in European Portuguese. We first present the main syntactic and discourse properties of different cleft structures and of "be"-fragments in European Portuguese, and we discuss how data from first language acquisition may contribute to…

The way in which an event is packaged linguistically can be informative about the number of participants in the event and the nature of their participation. At times, however, a sentence is ambiguous, and pragmatic information weighs in to favor one interpretation over another. Whereas adults may readily know how to pick up on such cues to…
