In this dissertation I report findings from two studies of the literacy abilities of children with Williams syndrome (WS), a genetic disorder associated with intellectual disability. I had two overarching goals: 1) evaluate the applicability of theories of reading and spelling acquisition developed based on typically developing children to…

We investigated performance levels on conducting continuous two-footed jumping of preschool children (4 years old) to high school students (16 years old) to clarify the developmental progression and sex differences in motor coordination and agility. In total, 450 children (boys: 227; girls: 223) participated in this study. We set 10 obstacles to…

The long-term negative consequences of learning difficulties have been acknowledged. Nonetheless, research is still scarce regarding the prediction of adolescent difficulties in reading and arithmetic skills. The present study examines at which age phase and with what kind of constellation of parent- and child-related factors can adolescent…

Most teachers report wanting more training and support to teach autistic students. Individual, autism-focused coaching is a promising approach for improving teacher self-efficacy and autistic student outcomes. Given the high workload demands of coaching, it must be feasible and acceptable. This study considers coaches', teachers', and autistic…

This research investigates whether and how two fundamental environmental factors--harshness and unpredictability--interact in regulating child and adolescent development, informed by life-history theory and drawing on data from the National Institute of Child Health & Human Development Study of Early Child Care and Youth Development (N =…

Purpose: Literacy instruction is within the scope of practice of speechlanguage pathologists (SLPs) and is a documented service provided among school-based SLPs. The purpose of this investigation was to replicate Davis and Murza's (2019) study of Virginia school-based SLPs in another geographic location. This study gathered information regarding…

The purpose of this document is to briefly introduce the research on Adverse Childhood Experiences (ACEs) and trauma and their relevance to schools. ACEs are acute or chronic events that threaten the child's physical or emotional well-being. This brief answers the following questions: (1) What are ACEs? (2) How common are ACEs? (3) What is trauma?…

Immigrant and refugee children and adolescents form a growing socially, culturally, and economically diverse group with the potential for wide-ranging adaptation outcomes. The goal of the study was to examine whether developmental competencies (social-emotional and academic) and sociodemographic disparities (e.g., SES and migration class)…

In August 2018, a new school discipline, Media Literacy and Informatics, was introduced in Switzerland. This article provides an overview of the current situation regarding the new school discipline, and its development. The article shows how schools already taught Media Literacy and Informatics. The article also sheds light on what Swiss parents…

The study aimed to explore how weight changes from childhood to adolescence influenced the performances of physical fitness. The participants (N = 115) were pre-tested when they were in kindergarten, first, or second grades (mean age = 7.25). The same participants were post-tested again after 6 years. The President's Challenge test battery was…

This book contains a compilation of papers presented at the International Psychological Applications Conference and Trends (InPACT) 2020, organized by the World Institute for Advanced Research and Science (W.I.A.R.S.), that this year had to be transformed into a fully Virtual Conference as a result of the Coronavirus (COVID 19) pandemic.

We used structural equation modeling in the Early Childhood Longitudinal Study--Kindergarten Cohort (N = 17,020) to explore the influence of having an older sibling on kindergarten-age focal children's cognitive self-regulation. In model 1, we tested how having a sibling who is generally older than the focal child contributes to the focal child's…

Background: In this work we sought to expand our knowledge of developmental trajectories of subcomponents of the language systems of individuals with intellectual disability (ID). We aimed to explore how "general" and "relational" vocabularies evolve as a function of cognitive level. Method: Developmental trajectories of…

School communities in both urban and rural settings need trauma-informed (TI) supports; however, the adversities experienced and access to student supports may be unique to rural school communities. In addition, the contextual challenges experienced by rural schools and communities, as well as the strengths that can be drawn from them, will…
