Linguistic expressions of locative spatial relations in sign languages are mostly visually motivated representations of space involving mapping of entities and spatial relations between them onto the hands and the signing space. These are also morphologically complex forms. It is debated whether modality-specific aspects of spatial expressions…

Previous studies using artificial languages suggest that sentence production can be guided by verb-specific as well as verb-general statistics present in the language input. Here we investigated whether the statistical properties of ongoing input in the speakers' native language systematically affected their sentence production. Three experiments…

San Juan Quiahije Chatino Sign Language (CSL) is a group of six family-based signed language varieties in rural Mexico. This study analyzes the variation of iconic patterns of CSL signs with respect to three semantic categories, tools, food, and animals, using an Embodied Cognitive Phonology framework. Signs are organized around iconic prototypes,…

This article focuses on the acquisition of mood in early complement clauses of European Portuguese (EP). Two semantic features are involved in the EP mood system--epistemicity and veridicality. An elicited production task administered to 80 children aged 4 to 9 showed that, even though children use the subjunctive in [-- epistemic] contexts, the…

Much has been said about children's strategies for mapping elements of meaning to words in toddlerhood. However, children continue to refine word meanings and patterns of word use into middle childhood and beyond, even for common words appearing in early vocabulary. We address where children past toddlerhood diverge from adults and where they more…

Deaf children whose hearing losses prevent them from accessing spoken language and whose hearing parents have not exposed them to sign language develop gesture systems, called "homesigns", which have many of the properties of natural language--the so-called resilient properties of language. We explored the resilience of structure built…

We investigated the effect of lexical stress on 16-month-olds' ability to form associations between labels and paths of motion. Disyllabic English nouns tend to have a strong-weak (trochaic) stress pattern, and verbs tend to have a weak-strong (iambic) pattern. We explored whether infants would use word stress information to guide word-action…

This dissertation provides a comprehensive analysis of the L2 acquisition of Spanish psych-verbs (e.g. "gustar" "to like") across four different proficiency levels. In particular, psych-verbs constitute a testing ground for the predictions of the Interface Hypothesis (Sorace and Filiaci, 2006; Tsimpli, Sorace, Heycok &…

Taking up analytical issues raised primarily in Dixon (2000) and Dixon & Aikhenvald (2000), this dissertation combines descriptive work with a medium-sized (50-language) typological study. Chapter 1 situates the dissertation against a concise survey of typological-functional work on causative constructions from the last few decades, and…

Previous studies with brain-injured patients have suggested that language abilities are necessary for complex problem-solving, even when tasks are non-verbal. In the current study, we tested this notion by analyzing behavioral and neuroimaging data from a large group of left-hemisphere stroke patients (n = 107) suffering from a range of language…

Since the late 1980s, collocations have received increasing attention in applied linguistics, especially language teaching, as is evidenced by the many publications on the topic. These works fall roughly into two lines of research (a) those focusing on the identification and use of collocations (Benson, 1989; Hunston, 2002; Hunston & Francis,…

Two-year-olds assign appropriate interpretations to verbs presented in two English transitivity alternations, the causal and unspecified-object alternations (Naigles, 1996). Here we explored how they might do so. Causal and unspecified-object verbs are syntactically similar. They can be either transitive or intransitive, but differ in the semantic…

Article omission is known to be a feature of early grammar, although it does not affect all child languages to the same extent. In this article we analyze the production of articles by 12 children, 4 speakers of Catalan, 4 speakers of Italian, and 4 speakers of Dutch. We consider the results in the light of (i) the adult input the children are…

Different languages map semantic elements of spatial relations onto different lexical and syntactic units. These crosslinguistic differences raise important questions for language development in terms of how this variation is learned by children. We investigated how Turkish-, English-, and Japanese-speaking children (mean age 3;8) package the…

This paper presents a discussion of the constraints imposed on lexicalisation during production by language-specific patterns, such as whether words exist in a language to describe a given event and whether language-specific syntactic and phonological information correlates with semantic properties. First, we introduce in broad strokes relevant…
