The Developmental Importance Of Napping In Preschool Children, Adam T. Newton

Electronic Thesis and Dissertation Repository

Most children cease napping between 2- and 5-years-old. Little is known about the predictors or outcomes related to this cessation, or the interrelation of different components of nap behavior. Four empirical studies were conducted to investigate the developmental importance of napping among preschool children.

Studies 1 and 2 used a large, longitudinal sample of Canadian children to investigate the predictors (Study 1) and outcomes (Study 2) related to early nap cessation. Early nap cessation was defined as stopping daytime sleep before three years old. In Study 1, parents reported on their own, child, and family functioning at two timepoints (0-1 …

Early Gaze Behaviours In Infants At High Familial Risk For Autism Spectrum Disorder: Association With Brain Development, Julia Teixeira Pinto Montenegro

Electronic Thesis and Dissertation Repository

Children diagnosed with Autism Spectrum Disorder (ASD) show impairments in gaze-following and will seldom engage in joint attention (JA). The ability to initiate JA (IJA) can be more impaired than the ability to respond to JA (RJA). In a longitudinal study, 101 high-risk infants for ASD (62% males) completed MRI scans at 4 or 6 months of age. Subcortical volumes (thalamus, basal ganglia, hippocampus, amygdala) were extracted. Gaze and JA behaviours were assessed with standardized measures. The majority of infants were IJA non-responders (n=93, 92%), and over half were RJA non-responders (n=50, 52%). In the non-responder groups, models testing the …

Screen Time Use And Children’S Mental Health During The Covid-19 Pandemic, Amira Hmidan

Electronic Thesis and Dissertation Repository

Parents with school-aged children have experienced numerous hardships during the 2020-2021 academic school year, including school closures, lockdowns, and travel restrictions. Higher levels of parent stress and screen time may adversely impact children’s behavioural outcomes. This longitudinal survey study examined the associations of parent stress, parenting styles, and prolonged screentime on internalizing and externalizing behaviours in school-aged children. Parents (n = 108) completed survey measures at two time points over the 2020-2021 academic school year. Two generalized estimating equations were performed. There was a significant positive interaction between parent stress and screen time (B = < .001; p = .001) …

An Exploration Of The Facilitators And Barriers Of Inclusion And Participation For Children With Intellectual And Developmental Disabilities At Informal Education Settings, Julia M. Ranieri

Electronic Thesis and Dissertation Repository

This dissertation addresses the current practices, facilitators, and barriers toward inclusion and participation for children with neurodevelopmental disorders, including intellectual and developmental disabilities (IDD) at informal education settings (IES). The first research paper is a scoping review examining practices for supporting participation at IES for children with neurodevelopmental disorders. Characteristics of studies, practices used to promote inclusion, and outcomes measures were identified. The findings of this study emphasized the current practices being utilized at IES for children with neurodevelopmental disorders.

The second research paper is qualitative descriptive study of the facilitators and barriers to inclusion for children with IDD at …
