Are There Shared Neural Correlates Between Dyslexia And Adhd? A Meta-Analysis Of Voxel-Based Morphometry Studies, Lauren M. Mcgrath, Catherine J. Stoodley

Psychology: Faculty Scholarship

Background

Dyslexia and Attention-deficit/hyperactivity disorder (ADHD) are highly comorbid neurodevelopmental disorders (estimates of 25–40% bidirectional comorbidity). Previous work has identified strong genetic and cognitive overlap between the disorders, but neural overlap is relatively unexplored. This study is a systematic meta-analysis of existing voxel-based morphometry studies to determine whether there is any overlap in the gray matter correlates of both disorders.

Methods

We conducted anatomic likelihood estimate (ALE) meta-analyses of voxel-based morphometry studies in which individuals with dyslexia (15 studies; 417 cases, 416 controls) or ADHD (22 studies; 898 cases, 763 controls) were compared to typically developing controls. We generated ALE …

Humor Improves Women’S But Impairs Men’S Iowa Gambling Task Performance, Jorge Flores‑Torres, Lydia Gómez‑Pérez, Kateri Mcrae, Vladimir López, Ivan Rubio, Eugenio Rodriguez

Psychology: Faculty Scholarship

The Iowa Gambling Task (IGT) is a popular method for examining real-life decision-making. Research has shown gender related differences in performance, in that men consistently outperform women. It has been suggested that these performance differences are related to decreased emotional control in women compared to men. Given the likely role of emotion in these gender differences, in the present study, we examine the effect of a humor induction on IGT performance and whether the effect of humor is moderated by gender. IGT performance and parameters from the Expectancy Valence Model (EVM) were measured in 68 university students (34 men; mean …

Neural Processing Of Infant And Adult Face Emotion And Maternal Exposure To Childhood Maltreatment, Aviva K. Olsavsky, Joel Stoddard, Andrew Erhart, Rebekah C. Tribble, Pilyoung Kim

Psychology: Faculty Scholarship

Face processing in mothers is linked to mother–infant social communication, which is critical for parenting and in turn for child development. Neuroimaging studies of child maltreatment-exposed (CME) mothers are sparse compared to studies of mothers with postpartum depression, which have suggested blunted amygdala reactivity to infant stimuli. We expected to see a similar pattern in CME mothers. Based on broader studies in trauma-exposed populations, we anticipated increased amygdala reactivity to negative adult face stimuli in a comparison task in CME mothers given heightened evaluation of potential threat. We examined Neuroimaging studies of mothers with childhood maltreatment exposure (CME) (18–37 years …

Across Continents And Demographics, Unpredictable Maternal Signals Are Associated With Children's Cognitive Function, Elysia Poggi Davis, Riikka Korja, Linnea Karlsson, Laura M. Glynn, Curt A. Sandman, Brian Vegetabile, Eeva-Leena Kataja, Saara Nolvi, Eija Sinervä, Juho Pelto, Hasse Karlsson, Hal S. Stern, Tallie Z. Baram

Psychology: Faculty Scholarship

Background

Early life experiences have persisting influence on brain function throughout life. Maternal signals constitute a primary source of early life experiences, and their quantity and quality during sensitive developmental periods exert enduring effects on cognitive function and emotional and social behaviors. Here we examined if, in addition to established qualitative dimensions of maternal behavior during her interactions with her infant and child, patterns of maternal signals may contribute to the maturation of children's executive functions. We focused primarily on effortful control, a potent predictor of mental health outcomes later in life.

Multivariate Genome-Wide Association Study Of Rapid Automatised Naming And Rapid Alternating Stimulus In Hispanic American And African–American Youth, Dongnhu Thuy Truong, Andrew Kenneth Adams, Steven Paniagua, Jan C. Frijters, Richard Boada, Dina E. Hill, Maureen W. Lovett, E Mark Mahone, Erik G. Willcutt, Maryanne Wolf, John C. Defries, Alessandro Gialluisi, Clyde Francks, Simon E. Fisher, Richard K. Olson, Bruce F. Pennington, Shelley D. Smith, Joan Bosson-Heenan, Jeffrey R. Gruen

Psychology: Faculty Scholarship

Background: Rapid automatised naming (RAN) and rapid alternating stimulus (RAS) are reliable predictors of reading disability. The underlying biology of reading disability is poorly understood. However, the high correlation among RAN, RAS and reading could be attributable to shared genetic factors that contribute to common biological mechanisms.

Objective: To identify shared genetic factors that contribute to RAN and RAS performance using a multivariate approach.

Methods: We conducted a multivariate genome-wide association analysis of RAN Objects, RAN Letters and RAS Letters/Numbers in a sample of 1331 Hispanic American and African-American youth. Follow-up neuroimaging genetic analysis of cortical regions associated with reading …

“A” For Effort: Rewarding Effortful Retrieval Attempts Improves Learning From General Knowledge Errors In Women, Damon Abraham, Kateri Mcrae, Jennifer A. Mangels

Psychology: Faculty Scholarship

Previous research has shown that the prospect of attaining a reward can promote task-engagement, up-regulate attention toward reward-relevant information, and facilitate enhanced encoding of new information into declarative memory. However, past research on reward-based enhancement of declarative memory has focused primarily on paradigms in which rewards are contingent upon accurate responses. Yet, findings from test-enhanced learning show that making errors can also be useful for learning if those errors represent effortful retrieval attempts and are followed by corrective feedback. Here, we used a challenging general knowledge task to examine the effects of explicitly rewarding retrieval effort, defined as a semantically …

Developmental dyslexia (DD) is one of the most prevalent learning disorders, with high impact on school and psychosocial development and high comorbidity with conditions like attention-deficit hyperactivity disorder (ADHD), depression, and anxiety. DD is characterized by deficits in different cognitive skills, including word reading, spelling, rapid naming, and phonology. To investigate the genetic basis of DD, we conducted a genome-wide association study (GWAS) of these skills within one of the largest studies available, including nine cohorts of reading-impaired and typically developing children of European ancestry (N = 2562–3468). We observed a genome-wide significant effect (p < 1 × 10−8) on rapid automatized naming of letters (RANlet) for variants on 18q12.2, within MIR924HG (micro-RNA …

B.F. Skinner's Theory Of Performance Excellence: A Radical Behavioral Perspective, Thomas Fritze

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Burrhus Frederic (B.F.) Skinner was a revolutionary in the field of psychology, particularly noted for his development of a philosophy of science and an approach to psychological study labeled radical behaviorism (Rachlin, 1995). To Skinner, psychology was synonymous with an organism's interactions between its environment and its own behavior - and behavior was defined accordingly. This way of studying psychology differed greatly from preceding behavioral iterations in psychology and kept up with advances in ·established fields of science. Due to the deficiencies of the behavioral tradition coming before Skinner, misunderstandings by many psychologists and scientists of the Skinnerian approach were …

Integration And Segmentation Conflict During Ensemble Coding Of Aspect Ratio, Elric Matthew Elias

Electronic Theses and Dissertations

The visual system often integrates information that "goes together". Once information has been integrated, summary information (e.g., average emotion or average size) can be extracted; this occurs during ensemble coding. Integration thus allows for fast and efficient generalizations about sets to be made. In contrast, the visual system sometimes segments input that does not go together. For example, the perception of objects can be exaggerated away from natural category boundaries (e.g., a perfect circle is a category boundary; it is neither "flat" nor "tall"). Segmentation allows the visual system to make quick categorical distinctions. Much of the time, integration …

Defining The Relationship: Intentional Decision-Making And Sexual Risk In Adolescent And Young Adult Romantic Relationships, Kayla Knopp

Electronic Theses and Dissertations

This dissertation presents three manuscripts addressing different sets of findings related to the "defining the relationship" (DTR) talk in adolescents' and young adults' romantic relationships. Paper 1 describes descriptive results from two studies, one utilizing a college undergraduate young adult sample (N = 341) and the other using a nationwide online sample of 15 to 17-year-old adolescents (N = 248). Key findings from Paper 1 indicate that DTR talks were used frequently in the relationships of young people, and were associated with relationship commitment and sexual behaviors. Paper 2 describes more in-depth analyses testing associations between having a …

A Dyadic Perspective On Young Adult Dating Aggression, Ann Lantagne

Electronic Theses and Dissertations

Guided by the dynamic developmental systems theory (Capaldi, Knoble, Shortt, & Kim, 2012), the present studies examined individual and relationship level risk factors for dating aggression. A series of Actor Partner Interdependence Models (APIM; Kenny, 1996; Kenny & Cook, 1999) were used to assess associations between males' and females' risk factors and dating aggression within 137 young adult couples. Findings indicated that both partners' reports of a number of relationship characteristics were associated with aggression, including negative interactions, satisfaction, jealousy, and anxious and avoidant relational styles. Moreover, there were actor partner interactions between male and female jealousy, anxious styles, and …

Beyond School Engagement: School Adaptation And Its Role In Bolstering Resilience Among Youth Who Have Been Involved With Child Welfare Services, Skyler S. Leonard

Electronic Theses and Dissertations

Objective: Youth involved with the child welfare system are at significant risk of poor school functioning and mental health. Little research has explored how the connection to school impacts known relationships between adversity and youth outcomes. The following project sought to shed light on the role of schools in conferring risk or resilience for youth in contact with the child welfare system, with regard to their mental health. The overall aims of this project were to (1) improve our conceptualization of school adaptation, with particular attention to individual variation along multiple dimensions of school adaptation, (2) examine the relationship of …

Anti-Fat Bias And Attentional Capture, Larissa Catherine Miller

Electronic Theses and Dissertations

Explicitly-rated anti-fat attitudes are correlated with weight-based discrimination, which is rampant in society today as many countries grapple with soaring rates of obesity. Early perceptual processes, such as conscious awareness and visual attention, may be biased based on the weight of the perceived or the perceiver, or any number of individual perceiver characteristics regarding weight-biased attitudes and experiences. The three experiments presented used continuous-flash suppression (CFS) to mask body stimuli, thereby hoping to gain insight into attentional capture of unseen images and its relation to anti-fat attitudes. The pattern of findings in the three experiments presented suggest that what makes …

Commitment And Romantic Alternative Monitoring, Lane Laurel Ritchie

Electronic Theses and Dissertations

This dissertation examines cognitive and behavioral factors involved in the management of potential alternative partners. Two studies are described here, each in a separate paper. The first study investigates perceptions of potential alternative partners as presented in an experimental paradigm (Study 1) and the second study examines links between alternative monitoring and relationship outcomes, measured longitudinally in survey research (Study 2). In the first study, Perceptual Downgrading and Relationship Commitment, I use a well-established paradigm to test a novel series of questions: Do individuals in committed relationships perceive attractive others as less attractive than single people do? This phenomenon …

Individual Adjustment As A Predictor Of Improvements In Romantic Relationship Quality From Adolescence To Adulthood, Jamie Novak Shoop

Electronic Theses and Dissertations

Previous work suggests that individuals who experience a poor quality romantic relationship during adolescence are at heightened risk of experiencing poor quality romantic relationships in adulthood. However, this literature has not yet identified factors that may predict which individuals will go on to experience improved romantic relationship quality in adulthood, despite having experienced a poor quality romantic relationship during adolescence. The goal of the current study was to examine whether adolescents' psychosocial adjustment (internalizing and externalizing symptoms, substance use, and self-esteem) predicted improvements in the quality of their subsequent romantic relationships. Data were drawn from a community sample of 200 …

The Cultural Transmission Of Gender Roles In Childhood, Sarah Ariel Lamer

Electronic Theses and Dissertations

In the present work, I summarize extant theories and evidence on how children learn about gender roles and test an ecological framework for gender-role learning (i.e., the Gendered Ecology Model). Existing theory has demonstrated that children begin to form symbolic representations of gender as young as 9 months and acquire basic gender stereotypes about behaviors and activities considered appropriate for each gender by 3 years. Theories have proposed several potential sources and moderators of how children learn about the roles that women and men generally hold. However, no theories have examined these sources from an ecological approach, leaving open the …

Social Support Satisfaction As A Protective Factor For Postpartum Maternal Distress, Amy-Lynn Elisabeth Anderson

Electronic Theses and Dissertations

Social support has been identified as a protective factor for postpartum maternal distress, a prevalent women's health issue, and most research focuses on the amount of support women receive. However, research in this area has failed to explore whether increasing satisfaction with social support may be a worthwhile approach to alleviating postpartum maternal distress, beyond increasing amounts. There is also little known regarding specific aspects of support, like satisfaction with emotional and instrumental support, that might lead to differences in postpartum distress outcomes. In this prospective, longitudinal study, we hypothesized that greater social support satisfaction will be associated with less …
