Effects Of Altered Prenatal Sensory Stimulation On Postnatal Contingency Learning In Bobwhite Quail Neonates (Colinus Virginianus), Namitha Raju

FIU Electronic Theses and Dissertations

Preterm infants are exposed to high levels of modified early sensory experience in the Neonatal Intensive Care Unit (NICU). Reports that preterm infants show deficits in contingency detection and learning when compared to full-term infants (Gekoski, Fagen, & Pearlman, 1984; Haley, Weinberg, & Grunau, 2006) suggest that their exposure to atypical amounts or types of sensory stimulation might contribute to deficits in these critical skills. Experimental modifications of sensory experience are severely limited with human fetuses and preterm infants, and previous studies with precocial bird embryos that develop in ovo have proven useful to assess the effects of modified perinatal …

Effects Of Prenatal And Early Postnatal Exposure To Aversive Stimuli On Fearfulness And Exploratory Behavior In Bobwhite Qauil Neonates (Colinus Virginianus), Michael Suarez

FIU Electronic Theses and Dissertations

Neophobia, the fear of novelty, is a behavioral trait found across a number of animal species, including humans. Neophobic individuals perceive novel environments and stimuli to have aversive properties, and exhibit fearful behaviors when presented with non-familiar situations. The present study examined how early life exposure to aversive novel stimuli could reduce neophobia in bobwhite quail chicks. Experiment 1 exposed chicks to a novel auditory tone previously shown to be aversive to naïve chicks (Suarez, 2012) for 24 hours immediately after hatching, then subsequently tested them in the presence of the tone within a novel maze task. Postnatally exposed chicks …

The Effect Of Prenatal Auditory Enrichment On Perceptual Narrowing In Bobwhite Quail Neonates, Briana O'Dowd

FIU Electronic Theses and Dissertations

The development of species-typical perceptual preferences has been shown to depend on a variety of socially and ecologically derived sensory stimulation during both the pre- and postnatal periods. The prominent mechanism behind the development of these seemingly innate tendencies in young organisms has been hypothesized to be a domain-general pan-sensory selectivity process referred to as perceptual narrowing, whereby regularly experienced sensory stimuli are honed in upon, while simultaneously losing the ability to effectively discriminate between atypical or unfamiliar sensory stimulation. Previous work with precocial birds has been successful in preventing the development of species-typical perceptual preferences by denying the organism …

Cognitive Behavior Therapy For Anxiety Disorders In Youth: Treatment Specificity And Mediation Effects, Ileana Hernandez

FIU Electronic Theses and Dissertations

The present study investigated the efficacies of Individual CBT (ICBT), Parent Relationship Skill Training (RLST, which targets increasing parental acceptance of youth and increasing autonomy granting) and Parent Reinforcement Skills Training (RLST, which targets increasing parental positive reinforcement and decreasing negative reinforcement). The specific aims were to examine treatment specificity and mediation effects of parenting variables. ICBT was used as a baseline comparison condition.

The sample consisted of 253 youth (ages 5-16 years; M = 9.38; SD = 2.42) and their parents. To examine treatment outcome and specificity, the data were analyzed using analysis of variance within a structural equation …

Exploring The Development Of Social Responses In Children With Callous And Unemotional Traits: An Examination Of The Impact Of Hypothesized Reinforcing And Aversive Stimuli, Andre Maharaj

FIU Electronic Theses and Dissertations

Callous and unemotional (CU) traits in children with conduct problems have been indicated as precursors to adult psychopathy. The analysis of the sensitivity to rewards and punishment in this population may be useful in the identification of effective behavior modification programs and particularly the delineation of ineffective punishment procedures. Scores on the Child Psychopathy Scale, Inventory of Callous and Unemotional Traits, Contingency Response Rating Scale and the Sensitivity to Reward Sensitivity to Punishment – Children Revised scale were used to evaluate 20 children, aged 7-13, recruited from FIU’s Center for Children and Families. The sample comprised 14 males and 6 …

Post-College Transition: A Study Of Evangelical Spirituality In Emerging Adulthood, Katharine R. Pals

FIU Electronic Theses and Dissertations

This thesis explores the question: How are the spiritual lives of evangelical Christian FIU graduates affected during the two to four years following their college graduation? In twenty mini-case studies participants describe their patterns in prayer life, devotion, community service outreach, and ways that they understand their own growth process as evangelical Christian emerging adults.

A total of twenty FIU alumni from the classes of 2009-2012 between the ages of 23 and 34 were interviewed in this study. The sample population of evangelical Christian FIU alumni was identified by the graduates’ previous membership in on-campus Christian organizations, including Campus Bible …

Mothers And Their Children: Harry Potter And Melanie Klein, Kristina Mur

FIU Electronic Theses and Dissertations

This thesis analyzes the mother-child relationship in the Harry Potter novels by using Melanie Klein’s object-relation based theory. I argue the mothers and their relationship with their offspring represent fragments of a whole complicated psyche. The characters are not analyzed as individuals, but instead as pieces, sometimes multiple pieces, of a whole psyche. When these characters and novels are taken together, a whole, multi-faceted person comes into view. Rowling depicts both good and bad mothers, and children who characterize different positions according to Klein. These positions are the paranoid-schizoid position with Harry Potter and the depressive position with Sirius Black …

Fiber Pathways For Language In The Developing Brain: A Diffusion Tensor Imaging (Dti) Study, Iris J. Broce

FIU Electronic Theses and Dissertations

The present study characterized two fiber pathways important for language, the superior longitudinal fasciculus/arcuate fasciculus (SLF/AF) and the frontal aslant tract (FAT), and related these tracts to speech, language, and literacy skill in children five to eight years old. We used Diffusion Tensor Imaging (DTI) to characterize the fiber pathways and administered several language assessments. The FAT was identified for the first time in children. Results showed no age-related change in integrity of the FAT, but did show age-related change in the left (but not right) SLF/AF. Moreover, only the integrity of the right FAT was related to phonology but …

Ethnic And American Identity Development: A Developmental Systems Approach, Alan Meca

FIU Electronic Theses and Dissertations

Given the role ethnic identity has as a protective factor against the effects of marginalization and discrimination (Umaña-Taylor, 2011), research longitudinally examining ethnic identity has become of increased importance. However, successful identity development must incorporate elements from both one’s ethnic group and from the United States (Berry, 1980). Despite this, relatively few studies have jointly evaluated ethnic and American identity (Schwartz et al., 2012). The current dissertation, guided by three objectives, sought to address this and several other gaps in the literature. First, psychometric properties of the Multigroup Ethnic Identity Measure (MEIM) and the American Identity Measure (AIM) were evaluated. …

Effects Of Increased Levels Of Prenatal Mesotocin On Postnatal Individual Recognition And Stress Responsiveness In Northern Bobwhite Quail (Colinus Virginianus), Brittany Yusko

FIU Electronic Theses and Dissertations

Oxytocin (OT) plays a key role in the mediation of social and stress behaviors across many species; however, the mechanism is still unclear. The present study investigated the influence of prenatal levels of mesotocin (MT; avian homologue of OT) on postnatal social and stress behavior in Northern bobwhite quail. Experiment one determined endogenous levels of MT during prenatal development using an enzyme-linked immunoassay kit. Experiment two examined the influence of increased MT during prenatal development on chicks' individual recognition ability and stress response to a novel environment. Experiment one showed MT levels increased significantly throughout embryonic development. Experiment two showed …
