The Influence Of Early Media Exposure On Children’S Development And Learning, Katherine Hanson Jul 2017

The Influence Of Early Media Exposure On Children’S Development And Learning, Katherine Hanson

Doctoral Dissertations

A number of studies suggest that the amount of early screen media exposure is related to negative developmental outcomes, namely poorer executive functioning and language skills (Anderson & Pempek, 2005). Television’s constant presence in the home could lead to potentially serious consequences for infants and toddlers. However, hypotheses attributing long-term negative outcomes to the direct effects of television on children are limited. There are no definitive mechanisms to explain how these effects are instantiated within children over time. Furthermore, the indirect influences of television on children remain entirely unexplored. Television’s impact can have a potentially greater indirect effect on young …


The Effect Of Unique Labels On Face Perception In Infancy, Hillary R. Hadley Nov 2016

The Effect Of Unique Labels On Face Perception In Infancy, Hillary R. Hadley

Doctoral Dissertations

Faces are universally important for a variety of reasons, ranging from identifying individuals to conveying social information. During the first year of life, infants’ experience with commonly encountered face groups shapes how infants perceive familiar and unfamiliar faces. Between 6 and 9 months of age, infants become worse at differentiating among individual faces from unfamiliar face groups (e.g., other-species faces), a process known as “perceptual narrowing”. Labeling faces from a previously unfamiliar face group has been found to promote individual-level differentiation, as well as expert neural processing for the face group. However, it is currently unclear what influences individual-level labels …


The Neural Correlates Of Emotion Reactivity And Regulation In Young Children With Adhd, Claudia I. Lugo-Candelas Nov 2016

The Neural Correlates Of Emotion Reactivity And Regulation In Young Children With Adhd, Claudia I. Lugo-Candelas

Doctoral Dissertations

Attention-deficit hyperactivity disorder (ADHD) is the most frequently occurring pediatric neurobehavioral disorder. Although emotion reactivity and regulation are frequently impaired in ADHD, few studies have examined these factors in preschool aged children with ADHD, and none have explored the neural correlates of emotion reactivity and regulation in this group though event-related potentials (ERPs). Children aged 4 to 7 with (n = 24) and without (n = 30) ADHD symptoms completed an attention task composed of four blocks: baseline, frustration, suppression, and recovery. In the frustration and suppression blocks, negative affect was induced by false negative feedback. During the …


Infants' Reasoning About Agents' Identity: The Case Of Sociomoral Kinds, Hernando Taborda Nov 2016

Infants' Reasoning About Agents' Identity: The Case Of Sociomoral Kinds, Hernando Taborda

Doctoral Dissertations

Recent studies in development psychology suggest that early on infants are able to distinguish characters who display a cooperative behavior from characters who display an antisocial behavior. The current research builds on these findings and aims at determining the extent to which infants possess the sociomoral distinction of “good” and “mean” agents. In particular, we propose that infants represent sociomoral behaviors through kind-based categories. This hypothesis was tested in the current research across 5 different experiments by investigating how infants represent the identity of agents in sociomoral situations. Experiment 1 used a looking-time paradigm to demonstrate 11-month-old infants’ bias to …


Bidirectional Relationships Between Maternal Parenting Behaviors And Conduct Disorder Symptoms In Preschool Children, Benjamin Rolon Arroyo Nov 2016

Bidirectional Relationships Between Maternal Parenting Behaviors And Conduct Disorder Symptoms In Preschool Children, Benjamin Rolon Arroyo

Doctoral Dissertations

Conduct disorder (CD) symptoms emerge in preschool children, and some evidence for bidirectional effects between maternal parenting behaviors and these symptoms has been found in school-age children and adolescents. However, the strength and pattern of these effects are unknown during the preschool years. The present study examined the bidirectional relationships between several key maternal parenting behaviors (negative affect, warmth, overreactivity, and laxness) and CD symptoms across the preschool years. Participants were 197 preschool children (M = 44.24 months, SD = 3.37; Girls = 92) exhibiting significant behavior problems and their mothers who participated in a 3-year longitudinal study. Maternal …


Infants' & Toddlers' Social Evaluations Of Trustworthy And Untrustworthy Faces, Ashley Lyons Jul 2016

Infants' & Toddlers' Social Evaluations Of Trustworthy And Untrustworthy Faces, Ashley Lyons

Doctoral Dissertations

Our understanding of the social world is highly influenced by the fast and automatic evaluations we make about others based on their facial appearance. The goal of the current studies is to explore the developmental origins of the particular face-trait evaluation of ‘trustworthiness.’ Experiment 1 tested whether 10-month-old infants differentiate between faces that adults rate as trustworthy and untrustworthy, and if they have a preference for one over the other in a crawling task. Experiment 2 tested whether 10-month-olds have implicit expectations about the social behavior of characters with trustworthy of untrustworthy faces in a looking-time task that presents infants …


Predicting Social Skills And Adaptability In Preschoolers With Behavior Problems, Nastassja Marshall Nov 2015

Predicting Social Skills And Adaptability In Preschoolers With Behavior Problems, Nastassja Marshall

Doctoral Dissertations

Social skills and adaptability have been associated with a host of positive child outcomes. However, previous research has rarely examined the extent to which child symptomatology and family environment are associated with social skills and adaptability in children. Furthermore, no studies have looked at these associations longitudinally in preschool children with behavior problems, for whom social functioning may be especially important. The current study examined the relationship of five predictors (child oppositional defiant disorder (ODD), child attention-deficit hyperactivity disorder (ADHD), marital conflict strategies, parental depression, and parental warmth) with social skills and adaptability measured in preschoolers with behavior problems at …


Estrogen-Sensitive Learning Is Not Affected By Combination Ethinyl Estradiol And Levonorgestrel Oral Contraceptive Use, Darlene F. Ficco Aug 2015

Estrogen-Sensitive Learning Is Not Affected By Combination Ethinyl Estradiol And Levonorgestrel Oral Contraceptive Use, Darlene F. Ficco

Doctoral Dissertations

Two studies were conducted to explore the cognitive effects of combination ethinyl estradiol and levonorgestrel contraceptive use during late adolescence and young adulthood. Three groups of females, naturally cycling, active pill phase, and hormone-free interval phase, were tested on a battery of estrogen-sensitive, i.e., place learning and word generation, and estrogen-insensitive, i.e., map drawing, mental rotation, digit span, story recall, and object recall, tasks. Study 2 was conducted as a means to replicate the findings observed in Study 1 and to manipulate task difficulty and sensitivity. Two measures of mood were administered, and salivary estradiol levels at time of testing …


Same-Sex Parent Socialization: Associations Between Gay And Lesbian Parenting Strategies And Child Behavioral Adjustment, Marykate T. Oakley Jul 2015

Same-Sex Parent Socialization: Associations Between Gay And Lesbian Parenting Strategies And Child Behavioral Adjustment, Marykate T. Oakley

Masters Theses

Cultural socialization has been linked with child development and outcome, but, to date, the majority of research has focused on race and ethnicity. However, since families headed by gay and lesbian parents experience stigma related to parental sexual orientation, socialization practices may be uniquely important for families headed by gay and lesbian parents. The present study examined same-sex parent socialization among 54 families headed by gay and lesbian parents (52 fathers, 43 mothers, 51 school-aged children) using a cultural socialization framework. Findings revealed that parents engaged in socialization along three dimensions: Cultural Socialization, Preparation for Bias, and Proactive Parenting. Children …


The Impact Of Television Program Diet On Children's Achievement, Heather J. Lavigne Nov 2014

The Impact Of Television Program Diet On Children's Achievement, Heather J. Lavigne

Doctoral Dissertations

In this study, three waves of data from the Panel Study of Income Dynamics’s Child Development Supplement were used to examine patterns of children’s early TV exposure and its influence on middle childhood and adolescence. Analyses examined the pathways of influence depending on whether a dosage (hours of exposure) or diet (proportion of content to total TV time) variable was used. Results revealed that, in a dosage model, violent hours of early TV exposure were associated with decreases in independent reading and increases in externalizing behavior problems, but these did not predict later achievement. Early educational TV amount of exposure …


The Role Of Napping On Memory Consolidation In Preschool Children, Laura Kurdziel Nov 2014

The Role Of Napping On Memory Consolidation In Preschool Children, Laura Kurdziel

Doctoral Dissertations

Nocturnal sleep has been shown to benefit memory in adults and children. During the preschool age range (~3-5 years), the distribution of sleep across the 24-hour period changes dramatically. Children transition from biphasic sleep patterns (a nap in addition to overnight sleep) to a monophasic sleep pattern (only overnight sleep). In addition, early childhood is a time of neuronal plasticity and pronounced acquisition of new information. This dissertation sought to examine the relationship between daytime napping and memory consolidation in preschool-aged children during this transitional time. Children were taught either a declarative or an emotional task in the morning, and …


Emotion In Adoption Narratives: Links To Close Relationships In Emerging Adulthood, Holly A. Grant-Marsney Nov 2014

Emotion In Adoption Narratives: Links To Close Relationships In Emerging Adulthood, Holly A. Grant-Marsney

Doctoral Dissertations

An adopted person develops a narrative or story to help make sense of his or her adoption. This narrative provides a window into how the adoptee understands the role of adoption in his or her life and articulates feelings and thoughts about it. Adolescent and emerging adult adoptees’ data from the Minnesota-Texas Adoption Research Project (MTARP) were examined. MTARP longitudinally followed 190 adoptive kinship networks, with varying levels of openness in the adoption, from childhood to emerging adulthood. The current study sought to understand how emotion (affective valence and specific emotions), as identified in the adoption narratives during adolescence and …


The Role Of Representational Flexibility In Toddlers' Manual Search, Lauren Hartstein Nov 2014

The Role Of Representational Flexibility In Toddlers' Manual Search, Lauren Hartstein

Masters Theses

In the model room task, children watch as a miniature toy is hidden somewhere in a scale model of a room and are asked to find the larger version of the toy in the corresponding place in the actual room. Previous work has shown that children under age three often perform very poorly on this task. One prominent theory for their failure is that they lack the ability to understand the model as both a physical object and as a symbolic representation of the larger room. An alternative hypothesis is that they need to overcome weak, competing representations of where …


The Emergence Of Dp In The Partitive Structure, Helen Stickney Sep 2009

The Emergence Of Dp In The Partitive Structure, Helen Stickney

Open Access Dissertations

This dissertation is a first look at English-speaking children’s acquisition of the syntax of the partitive. It presents four experiments that contrast three types of structures and examines how they interact with adjectival modification: the partitive, the pseudopartitive and complex nouns with prepositional adjuncts. The experimentation investigates whether children recognize that the Determiner Phrase (DP) in the partitive is a barrier to adjectival modification. The partitive is contrasted with the pseudopartitive –a minimal pair structure that lacks an internal DP. The data shows that children under the age of six do not distinguish between the partitive and the pseudopartitive. They …


Cross-Age Peer Tutoring In Dialogic Reading: Effects On The Language Development Of Young Children, Itsuko Jamie Udaka Sep 2009

Cross-Age Peer Tutoring In Dialogic Reading: Effects On The Language Development Of Young Children, Itsuko Jamie Udaka

Open Access Dissertations

There are certain ways of reading to young children that are more effective than others in increasing language, vocabulary, and building early literacy skills. Dialogic reading is a method to enhance shared book reading by providing a context for dialogue and interaction between the adult and the child. Dialogic reading has been shown to have positive effects on young childrens’ early literacy and language skills. Thus far, parents and teachers have used these techniques in the home and school in one-on-one or small group settings. However, results have been variable due to inconsistent implementation. The purpose of this study was …


Visuospatial Reasoning In Toddlers: A Correlational Study Of Door Task Performance, Iris Louella Price May 2009

Visuospatial Reasoning In Toddlers: A Correlational Study Of Door Task Performance, Iris Louella Price

Open Access Dissertations

Previous research using violation-of-expectation paradigms suggests that very young infants have a good understanding of unobserved physical events. Yet toddlers appear to lack this knowledge when confronted with the door task, a visuospatial reasoning task which parallels ones used in the habituation/looking time studies. Many studies have been conducted in an effort to determine why toddlers perform poorly on the door task yet the answer remains unclear. The current study used a correlational approach to investigate door task performance from both psychological (executive function), and neuroscience (prefrontal cortex) perspectives. Children between the ages of 2 ½ - 3 years were …


Do Actions Speak Louder Than Knowledge? Action Manipulation, Parent-Child Discourse And Children’S Mental State Understanding In Pretense, Dawn K Melzer Feb 2009

Do Actions Speak Louder Than Knowledge? Action Manipulation, Parent-Child Discourse And Children’S Mental State Understanding In Pretense, Dawn K Melzer

Doctoral Dissertations 1896 - February 2014

In the current study children 3-5 years of age (N = 75) participated in a mental state task to investigate the effect of action saliency on young children's appreciation of mental states during pretend play activities. They also engaged in a parent-child interaction period, including storybook reading and pretend play activities, in order to examine the relation between mental state term utterances and performance on the mental state task. Two actors appeared side-by-side on a television screen, either in motion or as static images; one actor had knowledge of the animal he was pretending to be; the other actor did …
