In this dissertation, I investigate how people navigate ambiguity in everyday speech, with a focus on quantifier-negation sentences. Combining corpus analysis, behavioral experiments, and computational modeling in the Rational Speech Act framework, I explore preferred interpretations of quantifier-negation and examine the contexts and prosodies…

The Mayan language Mam uses complex predicates to express events. Complex predicates map multiple semantic elements onto a single word, and consequently have a blend of lexical and phrasal features. The chameleon-like nature of complex predicates provides a window on children's ability to express phrasal combinations at the one-word stage of…

German plural formation appears unsystematic and largely arbitrary to many second language (L2) learners. While some approaches have attempted to identify patterns and rules to help L2 learners (e.g., Anton et al., 2017; Di Donato & Clyde, 2020; Kraiss, 2014), one central observation from linguistic analysis has been absent from pedagogical…

"Wh"-phrases in Mandarin have an interrogative (like English "what") and an indefinite (like English "a/some") interpretation. Previous comprehension studies find that children can access both interpretations around 4.5 years old; studies with younger children focus on production and find that children between 2 and…

Background: During grammatical treatment of children with developmental language disorder (DLD), it is natural for therapists to focus on the grammatical details of the target language that give the children special difficulty. However, along with the language-specific features of the target (e.g., for English, add -s to verbs in present tense,…

This study considers the performance of tone pronunciation and morpheme intelligibility by L2 Polish Mandarin learners. A mixed-effects ordinal regression model and Tukey's HSD multiple test were used to examine the start-point, end-point, of syllables as a means of assessing their intelligibility by L2 Polish learners regarding the tones with the…

This paper provides the first evidence of maternal speech--motherese--in Wichi, an indigenous language with a complex morphology spoken in the Gran Chaco region of Argentina. The corpus consists of 22 hours of video recordings from the daily life of three children, starting from their one-morpheme utterance period (MLU = 1) to the onset of…

The main goal of this tutorial is to promote the study of children with developmental language disorder (DLD) across different languages of the world. The cumulative effect of these efforts is likely to be a set of more compelling and comprehensive theories of language learning difficulties and, possibly, of language acquisition in general.…

We examined the unique contributions of prosodic awareness and morphological awareness to school-aged children's word reading and reading comprehension. A total of 110 elementary-age children from Grades 4 and 5 participated in the current study. To measure prosodic awareness, children were asked to listen to and reflect on the stress patterns of…

What determines consonant doubling in English? This question is pursued by using a large lexical database to establish systematic correlations between spelling, phonology and morphology. The main insights are: Consonant doubling is most regular at morpheme boundaries. It can be described in graphemic terms alone, i.e. without reference to…

Background: German participles are formed by a co-occurrence of prefixation and suffixation. While the acquisition of regular and irregular suffixation has been investigated exhaustively, it is still unclear how German children master the prosodically determined prefixation rule (prefix "ge-"). Findings reported in the literature are…

This study considers the role of L1 phonological influence in L2 English past tense morphology production by native speakers of Spanish, Mandarin, and Japanese. While these L1s share similar phonological restrictions on consonant cluster formation needed for English past tense morphology, differences arise in L1 syntax (only Mandarin lacks…

The present study examines the use of English lexical insertions to create humor by Jordanian university students. The data of the study are collected from spontaneous tape-recorded conversations from 62 participants of both males and females, representing different age groups (from 18-23 years old) and belonging to different specializations…

The ability to detect non-adjacent dependencies (i.e. between "a" and "b" in "aXb") in spoken input may support the acquisition of morpho-syntactic dependencies (e.g. "The princess 'is' kiss'ing' the frog"). Functional morphemes in morpho-syntactic dependencies are often marked by perceptual cues that render…

Linguists tend to believe that total complexity of human languages is invariable. In order to test this hypothesis empirically, we need to calculate the complexity in different domains of language structure: phonology, morphology, syntax, etc. In this paper I provide some guidelines for documenting tonal systems and evaluating their complexity. I…
