Previous studies have used semantic verb categories to compare how speakers with and without aphasia use verb types during narrative monologue discourse tasks. In this study, we explore the types of verbs used by speakers with and without aphasia during conversation. Using previously collected conversational discourse samples produced by 23 adults…

Purpose: Production of complex syntax is a hallmark of later language development; however, most of the research examining age-related changes has focused on adolescents or analyzed narrative language samples. Research documenting age-related changes in the production of complex syntax in elementary school-aged children in conversational language…

Purpose: The purpose of this study was to evaluate the construct validity of three sentence-focused diversity measures, intransitive verb diversity, transitive verb diversity, and third person (3P) subject diversity, using two methods: (a) group differentiation of late-talking (LT) toddlers from peers with typically developing (TD) language and…

Causation is a core feature of human cognition and language. How children learn about intricate causal meanings is yet unresolved. Here, we focus on how children learn verbs that express causation. Such verbs, known as lexical causatives (e.g., break and raise), lack explicit morphosyntactic markers indicating causation, thus requiring that the…

This dissertation examined two phonological and morphological changes in Ghamdi Arabic (GA), focusing on vowel harmony and gender distinctions. By comparing Prochazka's 1988 findings with recent data from 26 participants across two age groups. Participants consisted of 20 younger speakers (10 males and 10 females, ages 20 to 35) and six older…

This study was designed to investigate the translation of laws from Thai into English with a focus on the use of modal 'shall' in the translations. As the trend of plain legal English continues to rise in the contemporary legal environment, some legal practitioners -- lawyers, judges and legal drafters -- have perceived that the use of the modal…

Modals (e.g., "can," "must") vary along two dimensions of meaning: "force" (i.e., possibility or necessity), and "flavor" (i.e., possibilities relative to knowledge [epistemic], goals [teleological], or rules [deontic] …). Comprehension studies show that children struggle with both force and flavor…

Purpose: The Arabic verb system features a nonlinear root and pattern derivational morphology. Previous studies suggest that young Arabic and Hebrew speakers' early verb use is based on semantic complexity rather than derivational morphological structure. The present study examines the role of morphological and semantic complexity in the emergence…

Mandarin Chinese is widely believed to observe the Phrase Structure Condition (first proposed in Huang 1982; hereafter 'PSC'), a PF filter on phrase-structural representations that forbids the occurrence of two (or more) syntactic constituents in the postverbal field. This idea has proved highly important and influential, as witnessed by the fact…

Words that describe sensory perception give insight into how language mediates human experience, and the acquisition of these words is one way to examine how we learn to categorize and communicate sensation. We examine the differential predictions of the typological prevalence hypothesis and embodiment hypothesis regarding the acquisition of…

Differences in the sequence with which children pass the tasks in Wellman and Liu's (2004) theory of mind (ToM) battery is increasingly bringing into question the universal and cultural specifics of children's developing understanding of others' minds. Children from China, Iran, and Turkey pass the knowledge access (KA) task of the battery earlier…

This study investigates a second language (L2) speaker's use and learning of the Icelandic auxiliary verb "aetla" (pronounced /aihtla/) in the wild. This analytic focus is motivated by the L2 speaker's (Anna) own orientation to "aetla" as a learnable. We track Anna's use of "aetla" in naturally occurring social…

This paper presents a unified Arabic version of the English action verbs mentioned in Bloom's taxonomy (1956) that has been checked for validity and reliability by a panel of education experts. Methodologically, the Bloom's list of action verbs was first translated into Arabic by an expert professor of translation. Then, using a mixed-method…

The relationships between the use of nouns and verbs, and other word classes have been well established in the typical language development literature. However, questions remain as to whether the same relationships are seen in the language use of individuals who use graphic symbol-based augmentative and alternative communication (AAC). The aim of…

This study aims to investigate the distribution across genres and the collocation of three synonymous verbs "cease," "halt," and "stop." Data were drawn from the Corpus of Contemporary American English (COCA). The results from the distribution across genres shed light on the degree of formality of each verb. The verb…
