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 …
