S. Alexandra Burt; Elizabeth A. Shewark; Jeffrey Shero; Amber L. Pearson; Jenae M. Neiderhiser; Kelly L. Klump; Joseph S. Lonstein – Developmental Psychology, 2024
Prior theoretical and empirical research has highlighted links between positive parenting and the socioeconomic characteristics of the family's neighborhood, but has yet to illuminate the etiologic origins of this association. One possibility is that the various predictors of parenting outlined by Belsky (1984; e.g., characteristics of the child,…

Alexander Hill Waugh – ProQuest LLC, 2024
This dissertation consists of two distinct bodies of work. The first leverages a unique aspect of fire ant biology to investigate a potential role for a supergene in genetic assimilation. A supergene refers to a chromosome structural rearrangement, such as an inversion, that regulates the production of an alternative phenotype within a species. In…

Rachel L. Weisbecker; Lisabeth Fisher DiLalla – Developmental Psychology, 2024
Parenting behaviors have long been recognized as crucial to children's healthy development. However, examinations of the etiology of these behaviors are less prevalent. The current study investigated the driving forces behind parental warmth and discipline, particularly whether they are related more to traits within the parent or reactions to…

Dimitropoulos, Anastasia; Doernberg, Ellen A.; Russ, Sandra W.; Zyga, Olena – Journal of Autism and Developmental Disorders, 2022
Prader-Willi Syndrome (PWS) is a rare neurodevelopmental disorder associated with social cognitive challenges, and pretend play has been demonstrated as a tool to achieve developmental goals. Following previous report on feasibility and acceptability of a remote, play-based parent-training program (Zyga, Russ, & Dimitropoulos, 2018), we now…

Kasey L. Wozniak; Anna S. Grinath; Heather J. Ray; Devaleena S. Pradhan – Scholarship and Practice of Undergraduate Research, 2025
A key component of authentic undergraduate research experiences is supporting students in recognizing their agency to shape a research project and develop project ownership. Previous research has suggested design elements that could foster project ownership in course-based research experiences. However, research is needed to examine how these…

Matthew Dumican; Therese Reyers; Alyson Malczewski; Zoë Thijs – International Journal of Language & Communication Disorders, 2025
Objectives: The objective of this study was to examine baseline and longitudinal differences of self-reported dysarthria and dysphagia in the most common genetic subtypes of Parkinson's disease (PD) using the Parkinson's Progression Marker Initiative (PPMI) dataset. Methods: This was a retrospective, longitudinal study utilizing data from the PPMI…

Wu; Mustafa Sahin – American Journal on Intellectual and Developmental Disabilities, 2025
Developmental domains, such as cognitive, language, and motor, are key concepts of interest in longitudinal studies of intellectual and developmental disabilities (IDD). Normative scores (e.g., IQ) are often used to operationalize performance on standardized tests of these concepts, but it is the interval-distributed person-ability scores that are…

The Developmental Synaptopathies Consortium is a multisite natural history network studying rare, neurogenetic syndromes associated with synaptic dysfunction and developmental delays. One aim of the Consortium is clinical trial readiness, including identifying clinical concepts and validating their measurement. We evaluated the scope and…

Orazio Attanasio; Gabriella Conti; Pamela Jervis; Costas Meghir; Aysu Okbay – National Bureau of Economic Research, 2025
We evaluate impacts heterogeneity of an Early Childhood Intervention, with respect to the Educational Attainment Polygenic Score (EA4 PGS) constructed from DNA data based on GWAS weights from a European population. We find that the EA4 PGS is predictive of several measures of child development, mother's IQ and, to some extent, educational…

Anne Hoffmann; Elizabeth Berry-Kravis; Nancy Brady – Journal of Speech, Language, and Hearing Research, 2025
Purpose: Autism and fragile X syndrome (FXS) are both associated with pragmatic communication difficulties, but the pattern of strengths and weaknesses varies. Early pragmatic communication skills include using communication for different functions, such as behavior regulation or establishing/maintaining joint attention. This study examines…

Whether there is a relationship between oxytocin (OXT) use in labor and the risk of autism (ASD), and the nature of such relationship, is unclear. By integrating genetic and clinical data in a sample of 176 ASD participants, we tested the hypothesis that OXT is a marker for abnormal prenatal development which leads to impairments in the process of…

The study characterised differences in costs associated with raising a child between four rare disorders and examined the associations between these costs with clinical severity. Caregivers of 108 individuals with Prader-Willi, Angelman (AS), Chromosome 15q Duplication and fragile X (FXS) syndromes completed a modified Client Services Receipt…

Viktorsson, Charlotte; Lindskog, Marcus; Li, Danyang; Tammimies, Kristiina; Taylor, Mark J.; Ronald, Angelica; Falck-Ytter, Terje – Developmental Science, 2023
The ability to perceive approximate numerosity is present in many animal species, and emerges early in human infants. Later in life, it is moderately heritable and associated with mathematical abilities, but the etiology of the Approximate Number System (ANS) and its degree of independence from other cognitive abilities in infancy is unknown.…

Lisa R. Hamrick; Amanda Seidl; Bridgette L. Kelleher – American Journal on Intellectual and Developmental Disabilities, 2023
Automated methods for processing of daylong audio recordings are efficient and may be an effective way of assessing developmental stage for typically developing children; however, their utility for children with developmental disabilities may be limited by constraints of algorithms and the scope of variables produced. Here, we present a novel…

Iris Selten; Tessel Boerma; Emma Everaert; Ellen Gerrits; Michiel Houben; Frank Wijnen; Jacob Vorstman – Autism & Developmental Language Impairments, 2023
Background and Aim: Children with Developmental Language Disorder (DLD) are at an increased risk to develop behaviors associated with Autism Spectrum Disorder (ASD). The relationship between early language difficulties and the occurrence of ASD-related behaviors in DLD is poorly understood. One factor that may hinder progress in understanding this…
