Exploring The Role Of Generative Artificial Intelligence In Cultural Relevant Storytelling For Native Language Learning Among Children
(2024) Nanduri, Dinesh Kumar; Marsh, Diana E; Information Studies; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
In an era marked by the rapid disappearance of languages, UNESCO warns that nearly half of the world's linguistic heritage might soon become dormant. Despite its current health, Telugu has seen a decline in usage, reduced focus in India's educational systems, and overshadowing by dominant global languages. This thesis explores Generative Artificial Intelligence (GenAI) to counter this trend, focusing on its application in native language learning for children, key carriers of their ancestral tongues. Through scoping reviews and participatory design sessions with young Telugu-speaking learners and their guardians, the study investigates GenAI's role in enhancing language learning tailored to individual and cultural contexts. It highlights storytelling as a potent mechanism for language acquisition, facilitated by GenAI's ability to personalize learning experiences and bridge generational gaps. The research also addresses ethical considerations vital for designing GenAI tools, promoting inclusivity, bias mitigation, and cultural integrity protection. It showcases a future where technology helps prevent linguistic dormancy and empowers children to celebrate human language and cultural diversity.
ISOLATING EFFECTS OF PERCEPTUAL ANALYSIS AND SOCIOCULTURAL CONTEXT ON CHILDREN’S COMPREHENSION OF TWO DIALECTS OF ENGLISH, AFRICAN AMERICAN ENGLISH AND GENERAL AMERICAN ENGLISH
(2023) Erskine, Michelle E; Edwards, Jan; Huang, Yi Ting; Hearing and Speech Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
There is a long-standing gap in literacy achievement between African American and European American students (e.g., NAEP, 2019, 2022). A large body of research has examined different factors that continue to reinforce performance differences across students. One variable that has been a long-term interest to sociolinguists and applied scientists is children’s use of different dialects in the classroom. Many African American students speak African American English (AAE), a rule-governed, but socially stigmatized, dialect of English that differs in phonology, morphosyntax, and pragmatics from General American English (GAE), the dialect of classroom instruction. Empirical research on dialect variation and literacy achievement has demonstrated that linguistic differences between dialects make it more difficult to learn to read (Buhler et al., 2018; Charity et al., 2004; Gatlin & Wanzek, 2015; Washington et al., 2018, inter alia) and recently, more difficult to comprehend spoken language (Byrd et al., 2022, Edwards et al., 2014; Erskine, 2022a; Johnson, 2005; de Villiers & Johnson, 2007; JM Terry, Hendrick, Evangelou, et al., 2010; JM Terry, Thomas, Jackson, et al., 2022). The prevailing explanation for these results has been the perceptual analysis hypothesis, a framework that asserts that linguistic differences across dialects creates challenges in mapping variable speech signals to listeners’ stored mental representations (Adank et al., 2009; Clopper, 2012; Clopper & Bradlow, 2008; Cristia et al., 2012). However, spoken language comprehension is more than perceptual analysis, requiring the integration of perceptual information with communicative intent and sociocultural information (speaker identity). To this end, it is proposed that the perceptual analysis hypothesis views dialect variation as another form of signal degradation. Simplifying dialect variation to a signal-mapping problem potentially limits our understanding of the contribution of dialect variation to spoken language comprehension. This dissertation proposes that research on spoken language comprehension should integrate frameworks that are more sensitive to the contributions of the sociocultural aspects of dialect variation, such as the role of linguistic and nonlinguistic cues that are associated with speakers of different dialects. This dissertation includes four experiments that use the visual world paradigm to explore the effects of dialect variation on spoken language comprehension among children between the ages of 3;0 to 11;11 years old (years;months) from two linguistic communities, European American speakers of GAE and African American speakers with varying degrees of exposure to AAE and GAE. Chapter 2 (Erskine [2022a]) investigates the effects of dialect variation in auditory-only contexts in two spoken word recognition tasks that vary in linguistic complexity: a) word recognition in simple phrases and b) word recognition in sentences that vary in semantic predictability. Chapter 3 [Erskine (2022b)] examine the effects of visual and auditory speaker identity cues on dialect variation on literal semantic comprehension (i.e., word recognition in semantically facilitating sentences). Lastly, Chapter 4 [Erskine (2022c)] examines the effects of visual and auditory speaker identity cues on children’s comprehension of different dialects in a task that evaluates pragmatic inferencing (i.e., scalar implicature). Each of the studies investigate the validity of the perceptual analysis against sociolinguistcally informed hypotheses that account for the integration of linguistic and nonlinguistic speaker identity cues as adequate explanations for relationships that are observed between dialect variation and spoken language comprehension. Collectively, these studies address the question of how dialect variation impacts spoken language comprehension. This dissertation provides evidence that traditional explanations that focus on perceptual costs are limited in their ability to account for correlations typically reported between spoken language comprehension and dialect use. Additionally, it shows that school-age children rapidly integrate linguistic and nonlinguistic socioindexical cues in ways that meaningfully guide their comprehension of different speakers. The implication of these findings and future research directions are also addressed within.
USE OF MULTIMODAL COMMUNICATION IN PLAY INTERACTIONS WITH CHILDREN WITH AUTISM
(2020) Rain, Avery; Bernstein Ratner, Nan; Hearing and Speech Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
In typical adult-child interaction, adults tend to coordinate gesture and other nonverbal modes of communication with their verbalizations (multimodal communication). This study explored the effectiveness of multimodal communication with young children with autism spectrum disorders (ASD) to encourage child responses. The maternal use of verbal, nonverbal, and multimodal initiations and the subsequent response or lack of response of their child was examined in fifty mother/child video-recorded play interactions. Results indicated that mothers initiated multimodally at similar rates with children with lower and higher expressive language levels. Child response rates to multimodal communication initiations were higher than response rates to verbal-only or nonverbal-only initiations; this finding was consistent across low and high expressive language groups. Additionally, a significant positive correlation was found between maternal wait time after initiation and overall child response rate. These findings have important ramifications for clinical practice and parent training.
Alumni Perspectives on their Membership in an Intergenerational Participatory Design Team
(2018) McNally, Brenna; Druin, Allison; History/Library & Information Systems; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Participatory Design (PD) gives technology users an active role in the design of the technologies they are meant to use. PD methods have been adapted for research with children to facilitate the creation of technologies that better meet children’s desires and expectations. While the benefits HCI practitioners receive from working with children in PD can include developing more child-centric interfaces and finding surprising new innovations, research is less clear on the participants’ perceptions of their experience—such as how they perceive matters that affect them or what personal gains intergenerational PD team participants may receive from their participation. Investigating the retrospective perspectives of adult and child members of intergenerational PD teams may enable researchers to improve or develop practices that are better aligned with participant expectations. Recent work has begun to look into the gains adults perceive from their participation on traditional PD projects, and has begun to observe gains to children during their participation on PD teams. However, the retrospective perspectives of adult and child alumni who were members of intergenerational PD teams have yet to be investigated. To understand how alumni of intergenerational PD teams perceive matters that affected their membership, I conducted anonymous, online surveys and follow-up interviews with three distinct participant groups from an intergenerational PD team: child design partner alumni, parents of child alumni, and adult design partner alumni. Outcomes include new understandings of 1) the perspectives of child design partner alumni with regard to the ethics of their previous participation, 2) the gains child design partners experience and attribute to their PD team participation from the perspectives of both child alumni and their parents, and 3) the gains that adult design partners experience and attribute to their PD team participation and their perspectives on membership. Throughout these findings participants describe how participation in intergenerational PD impacted their desire and perceived ability to pursue new goals and activities throughout their lives through the development of new skills, competencies, and mindsets. From these findings, I then synthesize ten recommendations toward the goal of making intergenerational PD better support the people who are involved in it.
Linguistic Influences on Disfluencies in Typically-Developing French-English Bilingual Children
(2018) Azem, Andrea Sabrije; Ratner, Nan; Hearing and Speech Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
The connections among language proficiency, language complexity, and fluency have been well-researched in both typical and atypical monolingual populations. Though previous work indicates that bilingual individuals often demonstrate different patterns of disfluency in each of their languages, how or why this happens is largely unknown. Relationships among fluency, language proficiency, and language complexity were examined using the narrative and conversational speech samples of 9 French-English bilingual children. Mean length of utterance in words (MLUw) and percent grammatical utterances (PGU) were shown to strongly relate to rates of total disfluency. The proportion of disfluent function words across samples differed significantly from the proportion of disfluent content words, although rates of disfluency on individual parts of speech did not differ significantly between French and English. Further work is necessary in order to better understand the extent to which language proficiency and linguistic complexity interact and affect disfluency across bilingual populations.
BEHAVIORAL PROBLEMS OF CHILDREN IN L.A: EXTENDED FAMILY, NEIGHBORHOOD, AND NATIVITY
(2017) Kang, Jeehye; Cohen, Philip N.; Sociology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
This dissertation consists of three papers that examine the association between family living arrangements and internalizing and externalizing behavioral problems in children. With increasing immigration and growing heterogeneity in family forms, extended family members are of increasing importance in children’s lives. However, knowledge about extended family living arrangements is lacking. The first paper examines the association between the presence of co-resident extended kin and children’s internalizing and externalizing behaviors. Children in the sample were found to be disadvantaged in extended households, especially with regard to internalizing behaviors. This association was found mostly among married-parent extended households. Further, this pattern emerged more clearly among children of documented immigrants, compared to those with native-born parents and those whose parents were undocumented immigrants. These findings suggest a need to revisit previous theories on extended family living arrangements. The second paper examines what kinds of household extension are associated with child behavioral problems. I specify the types of household extension by their relation to the householder—vertical, horizontal, and non-kin. Results from the cross-sectional sample indicate that horizontal extension is associated with higher internalizing behavior problems in children. However, the results from fixed effects models suggest that this pattern may be due to selection effects. Fixed effects estimations show that children moving into vertically extended household increase externalizing behaviors or that children moving out of a vertically extended household decrease externalizing behaviors. I discuss what implications this type of transition represents. The third paper examines the interaction between extended family household structure and neighborhood characteristics on children’s behavioral functioning. Findings suggest that the co-residence with extended kin is associated with both higher internalizing and externalizing behaviors for children. Although the health disadvantage of living with extended kin seems to be independent of the neighborhood income and racial minority concentration levels, extended kin moderate the associations with neighborhood structure. The advantage of living in higher-income neighborhood strengthens for extended families, reducing internalizing behavioral problems in children. Minority concentrated neighborhood functions as an advantage for extended families, decreasing externalizing behavioral problems. I conclude with discussion of future research and policy implications.
Enclosure Without Containment: Treatment Center For At Risk Children
(2016) Do, Thuy; Ambrose, Michael; Architecture; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Suicide in young children seem to occur more frequently now than ever before. Children as young as five years old have been admitted to the intense patient Behavioral Health facilities. It is important that these enclosed facilities are comfortable for these children while they are under analysis and treatment. The difficulty in term of design for these facilities that they are particularly secluded and closed-off to the public for the protection of the children. However, if the design is successful, it will help to heal the children. This thesis will analyze on three issues with Behavioral Health facilities. The first problem is the design of Behavioral Health centers, which creates a feeling of enclosure and imprisonment. The second issue is the traditional architecture vernacular of these facilities. They are not well thought-out with the interest of the children. The third issue is the stigma that is attach to Behavioral Health centers. Society overlooks and stereotypes these children. These issues can be resolved through architecture. • Architecture can translate nature and natural elements into spatial experiences of reflection. • Architecture can affect mental health through space, form, function, light, and materials. • Architecture can provide an aesthetic that can sway or influence negative social stigmas and images that society holds on behavioral centers. • Architecture can provide defined enclosure without restrained containment while simultaneously offering protection. This thesis will explore these theories and apply them to the design of the children residential treatment facility in the Cheverly neighborhood in Prince George’s County, Maryland where at risk children can come together for support, to be treated, and become part of the community.
From the 1996 Welfare Law to the Great Recession: Essays on the Effect of Safety Net Changes on Employment and Income Trends
(2016) Trisi, Danilo Leandro; Graham, Carol; Public Policy; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
The United States safety net has undergone significant changes over the last three decades. In the early 1990s the Earned Income Tax Credit was expanded. The 1996 welfare law dramatically reduced access to cash assistance. SNAP (formerly food stamps) declined in the aftermath of the 1996 welfare law but rebounded during the 2000s. This dissertation analyzes how these safety net changes have affected the employment trends of single mothers and the income trends of families with children. The first essay examines different ways of measuring how cash assistance changed after the 1996 law. It reviews previous approaches and introduces two measures that meet the objectives of capturing the benefit level and accessibility of a safety net program independent of economic conditions and allowing for variation by year, state, and family size. The essay concludes by discussing how this methodology can be adapted to measure changes in SNAP and EITC policies. The second essay examines the employment trends of single mothers. The descriptive analysis shows how single mothers with the least educational attainment and those with the youngest children increased their employment the most between 1992 and 1999. The econometric analysis uses the safety net measures developed in the first essay to analyze the effect of safety net changes on the employment of single mothers. It finds that the EITC accounted for 36 percent of the employment increase among single mothers with a high school education or less between 1992 and 1999. The economy accounted for 20 percent, changes in cash assistance for 10 percent, and SNAP changes for 4 percent. The third essay examines how the level and composition of incomes of families with children changed between 1993 and 2012. These data show how the safety net has become more focused on supporting families with earnings and less helpful to families during periods of joblessness. Changes in the safety net drove a 16 percent decline in post-tax post-transfer family income of the poorest five percent of children between 1995 and 2005. The paper concludes by looking at the characteristics of children at different points in the income distribution.
Life Uncharted: Parenting Transgender, Gender-Creative, and Gay Children
(2016) Vooris, Jessica Ann; King, Katie; Women's Studies; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Gender non-conformity is often seen as an indication of a future queer sexuality, but children are thought to be too young to actually be gay or trans. Life Uncharted: Parenting Transgender, Gender-creative, and Gay Children seeks to answer questions about what it means to be a "transgender," "gender-creative," or "gay" child, and examines the experiences of families who parent against the norm, raising children who break assumptions about the body, gender, identity and desire. Drawing from media analysis, ethnography of parent blogs and family gender conferences, along with interviews with 28 families, I argue that these parents engage in "anticipation work" as they manage anxiety and uncertainty about their children's behavior, attempt to predict and manage their children's futures, and explain their decisions to others. While television documentaries offer simple narratives that often reify binary expectations of gender, and explain that transgender children are "trapped in the wrong body," my ethnographic research and interviews shows that defining a transgender or gender-creative or gay child is more complex and it is not always clear how to separate gender expression, identity, and sexuality. As children socially transition at younger ages, when memory is just beginning to form, their relationships to the body and the notion of being "transgender" is in flux. Parents emphasize being comfortable with ambiguity, listening to children and LGBTQ adults, and accepting that it’s not always possible to know what the future brings. These children’s lives are unfolding and in process, changing our notions of childhood, queerness and transness.
Maternal Experiences of Parenting Children with Autism Spectrum Disorder: A Qualitative Analysis
(2015) Duchene, Melissa S.; Jones Harden, Brenda; Human Development; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
Despite the increased prevalence rates of autism spectrum disorders (ASD) over the last two decades (Centers for Disease Control and Prevention, 2015), little is known about the parenting of children with ASD, including parenting behaviors, parent-child interactions, and how the specific characteristics of children with ASD affect parenting practices. The goals of this qualitative study were: (1) To explore parenting practices and behaviors among mothers of children with ASD; and (2) To illuminate the unique experiences of mothers raising children with ASD. Three research questions guided the inquiry: 1) What are the parenting practices and behaviors that mothers use with their preschool age children with ASD?; 2) What are the beliefs and experiences of mothers relative to raising preschool aged children with ASD?; and 3) What facilitates or hinders mothers' parenting of their preschool aged children with ASD? In this qualitative inquiry, six mothers and their preschool-age children with ASD were recruited from the Autism Center in a metropolitan children's hospital. Each mother participated in three 1-1 ½ hour long semi-structured audio-recorded interviews that entailed a series of open-ended questions about the unique experiences associated with raising a child with ASD. Two home observations and one public observation of mother-child interactions lasting 1-2 hours in length were conducted per family. Eleven themes emerged during the coding process: 1) positivity within the mother-child relationship, 2) schedules and routines, 3) strategies encouraging child cooperation, 4) crisis management, 5) perspectives on child's maladaptive behavior, 6) perspectives on child's abilities, 7) perceptions and experiences around public interfacing, 8) stress associated with caring for a child with ASD, 9) maternal resources, 10) interpersonal supports, and 11) ecological factors. These results shed light on factors that contribute to the everyday realities and experiences of parents who have children with ASD, thereby allowing for a more accurate understanding of their parenting approaches and behaviors. Findings from this study can be considered in the context of developing interventions focused on parenting children with ASD.
