Understanding The Home Spatial Environment, Nelcida L. Garcia

FIU Electronic Theses and Dissertations

Spatial thinking encompasses several related skills including understanding size, shape, translation and rotation of objects, and distance between objects. Individual differences in spatial thinking are important predictors of children’s math and science achievement, as well as later entry into Science, Technology, Engineering, and Mathematics (STEM) disciplines. This dissertation proposes Relational Developmental Systems Theory as a lens to study spatial development. Informed by Relational Developmental Systems Theory, two empirical studies examined whether mothers’ characteristics affected their parenting practices, and in turn, their children’s spatial abilities (i.e., mental rotation, spatial scaling). First, in a sample of 165 mother-child dyads, mothers’ spatial ability …

Cyber Dating Abuse Among Emerging Adult Latina Women, Yanet Ruvalcaba

FIU Electronic Theses and Dissertations

This dissertation examines the experience of cyber dating abuse victimization among Latina women in emerging adulthood. There is particular emphasis on investigating the relationship between cyber dating abuse victimization and risk and protective factors. Study one implemented a strength-based approach to investigating culturally relevant factors against cyber dating abuse victimization. The relationship between acculturation and familial social support varied based on the subtypes of abuse. Specifically, the best fitting pathways in the structural equation model indicated that Latinx cultural orientation was protective against sexual cyber dating abuse victimization, and this relationship was mediated by family support.

Study two focused on …

Emerging Adult College Students' Perceptions Of Immigrants: A Multisite Experimental Study, Alexa Dee Barton

FIU Electronic Theses and Dissertations

The United States (U.S.) has consistently had the largest populations of immigrants worldwide over the last two centuries, contributing to immigration’s ongoing importance as a political, social, economic, and health topic. A central point of focus has been attitudes toward immigration, which prior research has noted is influenced by both individual level and sociopolitical contextual factors. However, few studies have examined these attitudes comparatively across differing immigrant populations (e.g. nation of origin, type of immigration). Nor has the influence of perceivers’ stage of identity and social development been considered (e.g. emerging adult, generation of immigration, civic values). Utilizing quantitative methods, …

Infant And Child Multisensory Attention Skills: Methods, Measures, And Language Outcomes, Elizabeth V. Edgar

FIU Electronic Theses and Dissertations

Intersensory processing (e.g., matching sights and sounds based on audiovisual synchrony) is thought to be a foundation for more complex developmental outcomes including language. However, the body of research on intersensory processing is characterized by different measures, paradigms, and research questions, making comparisons across studies difficult. Therefore, Manuscript 1 provides a systematic review and synthesis of research on intersensory processing, integrating findings across multiple methods, along with recommendations for future research. This includes a call for a shift in the focus of intersensory processing research from that of assessing average performance of groups of infants, to one assessing individual differences …

Adolescent Social Networks And Violence In Rural Colombia, Ana L. Rodriguez De La Rosa

FIU Electronic Theses and Dissertations

This dissertation examines violence in adolescent social networks in the context of a rural and resource-limited community in the Caribbean region of Colombia. Utilizing mixed methods data (focus groups and surveys) from 242 school-enrolled adolescents, three empirical studies explored adolescent violence experiences in their community, school, and intimate partner violence relationships. Study one utilizes a social complexity framework and mixed methods design to address victimization. Social network data showed that adolescents' psychological and physical violence victimizations occurred across their community, household, school, and emotionally adverse relationships; and were more likely in girl-nominated relationships, a relationship that shared more alters or …

The Developmental Plasticity Of Fruit Fly Vision, John Paul Currea

FIU Electronic Theses and Dissertations

In this dissertation we explore the morphological and neural plasticity underlying vision at different scales—within and between species of Drosophila—to elucidate the role of eye development in the evolution of vision. In chapter 2, we offer a tool to accelerate large-scale research into compound eye morphology, and validate it on the eyes of several insect orders and image media. Then, in chapter 3 we demonstrate the developmental plasticity of eye morphology and neural summation in fruit flies, finding an interesting interplay between the two systems. In chapter 4, we elucidate the role of visual plasticity and neural summation in the …

Culture And Context's Influence On Hispanic Undergraduates' Perceptions Of Their Persistence Toward Stem Degree Attainment, Elsa I. Bravo

FIU Electronic Theses and Dissertations

This dissertation examines the influences of context and culture on Hispanic undergraduate’s in the STEM pipeline. Study one utilized systematic review methods to assess the effectiveness of STEM intervention programs on Hispanic undergraduates. A total of 45 STEM related databases were searched from March-September 2020 with no limitations. Although a total of 259 studies were identified, only one study was actually found to specifically focus on Hispanic populations and include empirically based evaluations. The one remaining study did not find a statistically significant intervention effect for four- year graduation rates. The lack of evidence highlights a gap in research or …

Associations Of Sociocultural Stressors With Psychological Distress And Self-Rated Health Among Hispanic Emerging Adults, Abir Rahman

FIU Electronic Theses and Dissertations

Emerging adulthood (18-25 years) is a distinct period of life, characterized by a high level of instability in the matters of romantic life, work, and challenging developmental undertakings. Various events related to these developmental tasks may leave lifelong impacts on emerging adult’s identities and health across adulthood. Further, due to the unstable nature of this period, individuals in this age group are vulnerable to various mental health problems. Hispanic emerging adults may be particularly at risk of experiencing adverse health outcomes, as on top of normative developmental stressors (e.g., increased autonomy, finding employment), they are often exposed to various chronic …

The Cerebellum's Relationship To Language Function Following Perinatal Stroke, Carolina Alexis Vias

FIU Electronic Theses and Dissertations

While recent studies have demonstrated the association between the cerebellum and higher-order cognitive functioning, it is still unclear how volumetric differences of specific regions of interests within the cerebellum across typical and atypical development are related to language function. We have done so by measuring the volume of cerebellar subregions of healthy controls, and compared the volume to behavioral measures of language function. We then followed with an analysis of the cerebellum’s relationship to language function following perinatal stroke, which provides us with a greater knowledge of the impact of a cortical injury on cerebellar development and the cognitive outcomes …

Former Foster Youth And Their Pursuit Of A College Degree, Lori Ann Gionti

Understanding more about the journey of former foster youth as they pursue a college degree will help to understand what barriers are faced and what supports enhance their likelihood of enrollment and graduation.

Study #1, a structured literature review, examined the scholarly literature on former foster youth and college. Data were collected through a library database search and Google Scholar. Descriptive, demographic-type information was compiled and …

The Development Of Reward Processing And Risky Behaviors In The Brain, Michelle L. Ramos

FIU Electronic Theses and Dissertations

Adolescence is a period of heightened risk taking which can lead to many negative consequences. This increased risk taking may be related to developmental changes in the reward processing system in the brain. The current study proposes to investigate individual differences in the development of the reward processing system as well as cognitive-based regulatory processes in the developing brain, and how heterogeneity in neural and autonomic activity related to these processes may predict risk-taking behavior. Despite crucial developmental changes in the reward system leading to hypersensitivity to reward, there is great variability in risk-taking and sensation seeking behaviors seen in …
