Not All Numbers Were Created Equal: Evidence The Number One Is Unique, Jenna L. Croteau
Not All Numbers Were Created Equal: Evidence The Number One Is Unique, Jenna L. Croteau
Masters Theses
Universally across modern cultures children acquire the meaning of the words one, two, and three in order. While much research has focused on how children acquire this knowledge and what this knowledge represents, the question of why children learn numbers in order has been comparatively neglected. To address this question, a non-verbal anticipatory looking task was implemented. In this task, 35 14- to 23-month-old infants were assessed on their ability to form implicit category structures for the numbers one, two, and three. We hypothesized that children would be able to form the implicit category structure for the number one …
Youth-Perceived Variability In Harsh Parenting From 8-14 Years As A Predictor Of Internalizing And Externalizing Symptoms At 15 Years, Ann E. Folker
Youth-Perceived Variability In Harsh Parenting From 8-14 Years As A Predictor Of Internalizing And Externalizing Symptoms At 15 Years, Ann E. Folker
Masters Theses
Harsh parenting behaviors have been shown to predict internalizing and externalizing symptoms in children. These symptoms of psychopathology can persist into adolescence, which can negatively impact social, academic, and emotional functioning. Most studies, however, focus on between-person differences in average harsh parenting, rather than within-person changes in harsh parenting over time. This variability in harsh parenting has a potentially unique impact on the development of adolescent psychopathology. The present study aims to understand if child/adolescent-perceived variability in harsh parenting over time (intraindividual variability; IIV) predicts higher levels of internalizing and externalizing symptoms in mid-adolescence, while controlling for average levels of …
Explicit Norms Promotes Costly Fairness In Children, Gorana Gonzalez
Explicit Norms Promotes Costly Fairness In Children, Gorana Gonzalez
Masters Theses
Children have an early-emerging expectation that resources should be divided fairly amongst agents, yet their behavior does not begin to align with these expectations until later in development. This dissociation between knowledge and behavior raises important questions about the mechanisms that encourage children to behave how they know they should behave. Here I tested whether explicitly invoking fairness norms encourages costly fair decisions in 4- to 9-year-old-children. I examine children’s responses to unequal resource allocations in the Inequity Game by varying the direction of inequity (advantageous versus disadvantageous inequity) and normative information (to be fair or to act autonomously). The …
Counting Sequences Are Processed Across Multiple Levels Of Cortical Hierarchy, Eli Zaleznik
Counting Sequences Are Processed Across Multiple Levels Of Cortical Hierarchy, Eli Zaleznik
Masters Theses
Learning the count list (one, two, three, …) is a critical stepping-stone for the acquisition of number concepts. Most research about counting, however, is done in the behavioral domain, and little is known about the neural representations underlying counting sequences. Here, we test the hypothesis that transitional knowledge within a counting sequence exist both at sensory and conceptual (ordinal and magnitude) levels. To test this hypothesis, we employed a passive-listening violation-to-expectation fMRI paradigm where adult participants heard auditory count sequences that were correct (4 5 6 7) or violated at the end (4 5 6 8; consecutiveness) and, orthogonally, that …
Mobile Technology Use And School Readiness In Low-Income Preschoolers, Trina M. Harmon
Mobile Technology Use And School Readiness In Low-Income Preschoolers, Trina M. Harmon
Masters Theses
Once a luxury, mobile devices are now utilized by most members of society, including those in even the poorest communities. Unfortunately, little research has examined the effects of mobile media use in young children, and even less on young children from low-SES communities. Past research on television, and preliminary research on mobile technology, suggests that mobile media may affect school readiness, and that the direction and strength of this relation could depend on the content and context of the use. The current study examined the relation between mobile media use and a composite school readiness measure that included preliteracy, emergent …
Slow Wave Sleep In Naps Supports Episodic Memories In Early Childhood, Sanna Lokhandwala
Slow Wave Sleep In Naps Supports Episodic Memories In Early Childhood, Sanna Lokhandwala
Masters Theses
Naps have been shown to benefit declarative memories in early childhood. This benefit has been associated with sleep spindles during the nap. However, whether young children’s naps and their accompanying physiology benefit other forms of declarative learning is unknown. Using a novel storybook task, we found performance was better following a nap compared to performance following an equivalent interval spent awake. Moreover, performance was better the following day if a nap followed learning. Further, change in post-nap performance was positively associated to the amount of time spent in slow wave sleep. This suggests that slow wave sleep in naps may …
Children's Understanding Of Compositionality Of Complex Numerals, Jihyun Hwang
Children's Understanding Of Compositionality Of Complex Numerals, Jihyun Hwang
Masters Theses
Counting is the first formal exposure for children to learn numerals, which are constructed with a set of syntactic rules. Young children undergo many stages of rote-memorization of the sequence and eventually count through 100. What core knowledge is necessary to expand their number knowledge to higher numbers? The compositionality of numerals is a key to understanding the natural number system as in learning languages. Higher numbers (e.g., two hundred five) are constructed with the lexical items such as earlier numbers (e.g., one to nine) and multipliers. If children develop their understanding of the compositionality of numerals, they might comprehend …
Differential Harsh Parenting And Sibling Differences In Conduct Problems: The Role Of Effortful Control, Yelim Hong
Differential Harsh Parenting And Sibling Differences In Conduct Problems: The Role Of Effortful Control, Yelim Hong
Masters Theses
Differential parenting has been shown to be an important correlate and possible cause of positive and negative adjustment of sibling children. However, it is not known whether sibling differences in temperament affect this link between differential harsh parenting and sibling differences in adjustment outcomes. The current study addressed this gap in knowledge. The sample included 92 monozygotic (MZ, 63% female) twin pairs and 137 dizygotic same-sex (DZ, 52% female) twin pairs who had complete temperament survey data collected near the third annual wave in the longitudinal study. Children were 6.09 years old (SD = .69) years old at wave 1. …
Recursion In Language And Number: Is There A Relationship?, Diego Guerrero
Recursion In Language And Number: Is There A Relationship?, Diego Guerrero
Masters Theses
Numbers are an important part of the cultural knowledge in the modern world. Its use is fundamental in the conception and development of modern science. There are different sets of numbers called numerical systems. The most frequently used numerical system is the set of natural numbers that is composed of positive integers. Natural numbers have several forms to express the cardinality; the most frequently used is the base-10 number system, it represents the number using base quantities and powers of ten. For example, the current calendar year could be expressed as 2018 ; it’s notation describes the additive and multiplicative …
Early Neural And Environmental Predictors Of Later Emotion Dysregulation In Children With And Without Adhd Symptoms, Shannon Gair
Early Neural And Environmental Predictors Of Later Emotion Dysregulation In Children With And Without Adhd Symptoms, Shannon Gair
Masters Theses
Attention deficit/hyperactivity disorder (ADHD) is one of the most common childhood neurodevelopmental disorders and is characterized by excessive inattention and/or hyperactivity and impulsivity. There is evidence that many children with ADHD experience emotion dysregulation, but little is known about the mechanisms by which children with ADHD develop difficulties with emotion dysregulation. The goal of the present study is to identify early neural and environmental predictors of emotion dysregulation and determine whether these factors interact in contributing to later emotion dysregulation. In this study, children (aged 4-7) with ADHD symptoms and typically developing children participated. Measures of emotion socialization and neural …
The Effects Of Reward And Risk Level Associated With Speeded Actions: Evidence From Behavior And Electroencephalography, Xingjie Chen
The Effects Of Reward And Risk Level Associated With Speeded Actions: Evidence From Behavior And Electroencephalography, Xingjie Chen
Masters Theses
Choosing a course of action in our daily lives requires an accurate assessment of the associated risks as well as the potential rewards. The present two studies investigated the mechanism of how reward and risk level influence the motor decisions of speeded actions (Chapter 2) and its neural dynamics (Chapter 3) by focusing on the beta band (15-30 Hz) oscillation patterns reflected in the EEG signals. Participants performed a modified version of the Go-NoGo task, in which they earned reward points based on the speed and accuracy of response. On each trial, the reward points at stake (120 vs. 6) …
Influence Of Household Chaos On Associations Between Physiology And Behavior, Sarah Mccormick
Influence Of Household Chaos On Associations Between Physiology And Behavior, Sarah Mccormick
Masters Theses
Internalizing behaviors, or behaviors related to behavioral inhibition and the tendency to withdraw from novelty or uncertainty, are stable over time. There is substantial evidence indicating the association between greater resting right lateralized frontal EEG alpha asymmetry and negative affect as well as internalizing behaviors (Coan & Allen, 2003; Henderson, Fox, & Rubin, 2001; Fox, 1991). Further, right frontal asymmetry has been shown to be a stable marker of the presence of psychosocial risk (e.g. child maltreatment; see Peltola, Bakermans-Kranenburg, Alink, Huffmeijer, Biro, & van IJzendoorn, 2014 for meta-analyses). However, little is known about the influences of the home and …
Children's Self-Regulation During Reward Delay, Abigail Fontaine
Children's Self-Regulation During Reward Delay, Abigail Fontaine
Masters Theses
Individuals who display high levels of reward sensitivity are motivated by and respond to reward related cues, thus exhibiting more approach-motivated behaviors. A majority of the research on physiological indices of reward sensitivity in relation to self-regulatory abilities has focused on adults or adolescents, with relatively little work examining these associations in children. Thus, the current study sought to examine whether a common neural measure of reward sensitivity, left frontal electroencephalogram (EEG) asymmetry, assessed in early childhood was predictive of children’s later self-regulation abilities in the context of reward delay. Emerging inhibitory control skills were also examined as a potential …
Understanding Relational Competence In Emerging Adult Adoptees: A New Way To Conceptualize Competence In Close Relationships, Krystal K. Cashen
Understanding Relational Competence In Emerging Adult Adoptees: A New Way To Conceptualize Competence In Close Relationships, Krystal K. Cashen
Masters Theses
Relatively little research has focused on the positive adjustment of emerging adult adoptees (Palacios & Brodzinsky, 2010). Given the developmental context of emerging adulthood (Arnett, 2000), it is important to select a measure of adjustment that reflects the increased ambiguity seen in this time period. The present study aims to develop and validate a measure of relational competence, or competence in one’s closest relationship regardless of relationship type (i.e., romantic vs. nonromantic). This measure will be created by adapting the Romantic Competence Interview, a measure of romantic competence previously used with emerging adults (Shulman, Davila, & Shachar-Shapira, 2011). Participants …
Same-Sex Parent Socialization: Associations Between Gay And Lesbian Parenting Strategies And Child Behavioral Adjustment, Marykate T. Oakley
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 Role Of Representational Flexibility In Toddlers' Manual Search, Lauren Hartstein
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 …
