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…

In this study, we propose a hypothesis that domain-general auditory processing, a perceptual anchor of L1 acquisition, can serve as the foundation of successful post-pubertal L2 learning. This hypothesis was tested with 139 post-pubertal L2 immersion learners by linking individual differences in auditory discrimination across multiple acoustic…

This article explores how multiple linguistic cues interact in predictive processing among second language (L2) learners. In a visual-world eye-tracking experiment, we investigated whether learners of German use case and prosody cues together to assign thematic roles and predict post-verbal arguments. During the experiment, participants listened…

The study investigates the relationship between lexical encoding and production in order to establish whether learners are able to produce a difficult contrast in words that they merged in their mental lexicon. Forty American English learners of Russian were tested on their production and lexical encoding of familiar and highly-frequent words with…

Background: Phonological difficulties in children with developmental language disorder (DLD) are well documented. However, abilities regarding prosody, the rhythmic and melodic characteristics of language, have been less widely studied, particularly in Spanish. Moreover, the scant research findings that have been reported are contradictory. These…

To avoid potential miscommunication resulting from structural ambiguity, speakers and listeners often rely on differences in prosodic realization. For instance, the sentence "Jennifer blackmailed the boss of the clerk [who was dishonest"][subscript RC'] is realized with different prosody depending on the attachment of the relative clause…

Using a novel emotional perspective-taking task, this study investigated 4-year-olds' (n = 97) use of a speaker's emotional prosody to make inferences about the speaker's emotional state and, correspondingly, their communicative intent. Eye gaze measures indicated preschoolers used emotional perspective inferences to guide their real-time…

Purpose: The acquisition of literacy skills influences the perception and production of spoken language. We examined if orthography influences implicit processing in speech production in child readers and in adult readers with low and high reading proficiency. Method: Children (n = 17), adults with typical reading skills (n = 17), and adults…

The present study investigates the comprehension of syntactic and affective prosody in adults with autism spectrum disorder without accompanying cognitive deficits (ASD w/o cognitive deficits) as well as age-, education- and gender-matched unimpaired adults, while processing orally presented sentences. Two experiments were conducted: (a) an…

Studies have begun to focus on what skills contribute to the development of phonological awareness, an important predictor of reading attainment. One of these skills is the perception of prosody, which is the rhythm, tempo and stress of a language. To examine whether prosodic perception contributes to phonological awareness prior to reading…

This study investigates whether developmental dyslexia involves an impairment in implicit phonological representations, as distinct from orthographic representations and metaphonological skills. A group of adults with dyslexia was matched with a group with no history of speech/language/literacy impairment. Tasks varied in the demands made on…

Numerous studies have reported an effect of prosodic information on parsing but whether prosody can impact even the initial parsing decision is still not evident. In a visual world eye-tracking experiment, we investigated the influence of contrastive intonation and visual context on processing temporarily ambiguous relative clause sentences in…

Sarcasm, or sarcastic irony, involves expressing a message that is often opposite of the literal meaning of what is being said, in a way that may sound bitter, or caustic (Gibbs, 1986). In the past, sarcasm has been viewed as a method of introducing the possibility of alternative interpretations of a discourse, by creating ambiguity as to the…

We assessed the relationship between brain structure and function in 10 individuals with specific language impairment (SLI), compared to six unaffected siblings, and 16 unrelated control participants with typical language. Voxel-based morphometry indicated that grey matter in the SLI group, relative to controls, was increased in the left inferior…

This paper evaluates two classes of hypotheses about how people prosodically segment utterances: (1) meaning-based proposals, with a focus on Watson and Gibson's (2004) proposal, according to which speakers tend to produce boundaries before and after long constituents; and (2) balancing proposals, according to which speakers tend to produce…
