Item How Grammars Grow: Argument Structure and the Acquisition of Non-Basic Syntax(2019) Perkins, Laurel; Lidz, Jeffrey; Linguistics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This dissertation examines the acquisition of argument structure as a window into the role of development in grammar learning. The way that children represent the data for language acquisition depends on the grammatical knowledge they have at any given point in development. Children use their immature grammatical knowledge, together with other non-linguistic conceptual, pragmatic, and cognitive abilities, to parse and interpret their input. But until children have fully acquired the target grammar, these input representations will be incomplete and potentially inaccurate. Our learning theory must take into account how learning can operate over input representations that change over the course of development. What allows learners to acquire new knowledge from partial and noisy representations of their data, one step at a time, and still converge on the right grammar? The case study in this dissertation points towards one way to characterize the role of development in grammar acquisition by probing more deeply into the resources that learners bring to their learning task. I consider two types of resources. The first is representational: learners need resources for representing their input in useful ways, even early in development. In two behavioral studies, I ask what resources infants in their second year of life use to represent their input for argument structure acquisition. I show that English learners differentiate the grammatical and thematic relations of clause arguments, and that they recognize local argument relations before they recognize non-local predicate-argument dependencies. The second type of resource includes mechanisms for learning from input representations even when they are incomplete or inaccurate early in development. In two computational experiments, I investigate how learners could in principle use a combination of domain-specific linguistic knowledge and domain-general cognitive abilities in order to draw accurate inferences about verb argument structure from messy data, and to identify the forms that argument movement can take in their language. By investigating some of the earliest steps of syntax acquisition in infancy, this work aims to provide a fuller picture of what portion of the input is useful to an individual child at any single point in development, how the child perceives that portion of the input given her current grammatical knowledge, and what internal mechanisms enable the child to generalize beyond her input in inferring the grammar of her language. This work has implications not only for theories of language learning, but also for learning in general, by offering a new perspective on the use of data in the acquisition of knowledge.Item An Affiliative Model of Early Lexical Learning(2019) Tripp, Alayo; Feldman, Naomi; Idsardi, William; Linguistics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)In defining the language acquisition problem, traditional models abstract away effects of variability, defining the learner as acquiring a single language variety, which is spoken homogeneously by their speech community. However, infants are exposed to as many unique varieties of speech as they are speakers. Adult sociolinguistic competence is also characterized by the capacity to employ and interpret non-phonological linguistic distinctions which are associated with different social groups, including ‘code-switching’ or ‘style-shifting’ between languages and speech registers. This dissertation presents a model of infant lexical acquisition which assumes that learners monitor linguistic sources for variation in reliability. This model is adapted from Shafto, Eaves, Navarro, and Perfors (2012) which the authors used to describe the behavior of preschool children in selecting sources to learn labels from in K. Corriveau and Harris (2009) and M. Corriveau and Harris (2009). I show that this probabilistic model effectively simulates two experiments from the literature on preverbal infants’ perception of labeling, Rost and McMurray (2009) and Koenig and Echols (2003). Evidence suggests that the receptiveness of preverbal infants to novel lexical items is correlated with infant beliefs regarding the informant’s knowledgeability and social group membership. These simulations demonstrate that language learners may well be recruiting processes of epistemic trust to guide lexical acquisition much earlier than previously suggested. We should therefore expect even very young listeners to respond differently to dialects not solely as a function of exposure, but also as a function of attitudes towards the speech determined by the quality of that exposure. Developmental differences between populations in attention to non-linguistic affiliative cues are therefore expected to emerge early and have significant effects on language outcomes. Measures of online language proficiency may be vulnerable to significant bias owing to the activation of sociolinguistic biases in the presentation of test items. Differences in the breadth or specificity of listener preferences for speakers in turn predict differences in task complexity for learners of standard and non-standard dialects. A new research program in early sociophonetic perception, uniting accounts of selective trust with language learning has the potential to deepen understanding of both typical and disordered language development.Item Reimagining Resilience: Exploring Black Early Adolescent Girls’ Experiences, Desires, and Needs While Growing Up In Baltimore City(2018) Akoumany, Stephanie Yvonne; Parks, Sheri L; American Studies; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)"Reimagining Resilience: Exploring Black Early Adolescent Girls’ Experiences, Desires, and Needs While Growing Up In Baltimore City" asks the following research questions: What are black early adolescent girls’ resilience strategies while growing up in poor and working class communities in Baltimore City? What are the girls’ perceptions of their own life experiences, desires, needs, and the quality of their interpersonal relationships? This dissertation is informed by a three year longitudinal ethnographic and participant action research study, conducted from 2010-2013, at a Baltimore City public school. Eighty-five, hour-long, weekly and biweekly workshops were conducted with 55 black middle school girls between the ages of 11-14 years old, who were in three different grade-based cohorts, until their respective eighth grade graduations. The black early adolescent girls in this study shared that their major stressors were feeling misunderstood, increased domestic and academic responsibilities as they transitioned into adolescence, conflicts with peers and adults, cyberbullying on popular social media sites, race, gender, and class stigmatization and policing at school, a lack of social supports, pressure to engage in sexual activities, physical and sexual violation, navigating structurally decaying neighborhoods, and community violence. This dissertation argues that black early adolescent girls utilize resilience strategies, particularly, self-assertion, storytelling, creativity, play, and community building to cope with these daily stressors and other traumatic life events. This dissertation explores connections between adolescent development, relational aggression, adverse childhood experiences, emotional intelligence, neuroplasticity, and resilience. It suggests that holistic wellness approaches such as mindfulness and play based therapy, socioemotional learning opportunities, restorative justice, facilitated intergroup dialogue, story exchange, participant action research, and comprehensive and medically accurate sexual education interventions that listen to black girls’ perceptions of their own experiences and needs can help schools promote health equity among adolescents in Baltimore City, the United States, and the world.Item Pragmatic enrichment in language processing and development(2013) Lewis, Shevaun; Phillips, Colin; Linguistics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The goal of language comprehension for humans is not just to decode the semantic content of sentences, but rather to grasp what speakers intend to communicate. To infer speaker meaning, listeners must at minimum assess whether and how the literal meaning of an utterance addresses a question under discussion in the conversation. In cases of implicature, where the speaker intends to communicate more than just the literal meaning, listeners must access additional relevant information in order to understand the intended contribution of the utterance. I argue that the primary challenge for inferring speaker meaning is in identifying and accessing this relevant contextual information. In this dissertation, I integrate evidence from several different types of implicature to argue that both adults and children are able to execute complex pragmatic inferences relatively efficiently, but encounter some difficulty finding what is relevant in context. I argue that the variability observed in processing costs associated with adults' computation of scalar implicatures can be better understood by examining how the critical contextual information is presented in the discourse context. I show that children's oft-cited hyper-literal interpretation style is limited to scalar quantifiers. Even 3-year-olds are adept at understanding indirect requests and "parenthetical" readings of belief reports. Their ability to infer speaker meanings is limited only by their relative inexperience in conversation and lack of world knowledge.
