Identifying Cognitive Profiles In Children With Neurodevelopmental Disorders Using Online Cognitive Testing, Abagail Hennessy

Electronic Thesis and Dissertation Repository

Neurodevelopmental disorders (NDDs), including autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD), are characterized by diverse cognitive deficits. Early identification of cognitive deficits is fundamental to improving academic and emotional/behavioural outcomes in children. Creyos has pioneered online cognitive testing which assesses working memory, attention, reasoning and verbal abilities. We developed audiovisual instructions for the task battery and implemented them in an online sample of children ages 4-16 with ADHD (n = 83), ASD (n = 37), and typically developing children (TD) (n = 86), to determine whether unique cognitive profiles would emerge. Four tasks reflective of working memory, …

Examining The Relationship Between Child Maltreatment, Executive Functioning, And Trauma Appraisal, Myshira Oliver

Dissertations

Problem

A current problem is that although child maltreatment has been demonstrated to be negatively associated with both executive functioning and trauma appraisal (leading to feelings of shame, self-blame, etc.), there is not an established model within the literature that explains the relationship between child maltreatment, executive functioning, and trauma appraisal. The purpose of this study was to develop a model that displayed the relationship between child maltreatment, executive functioning, and trauma appraisal. Additionally, this study sought to discover differences in trauma appraisal and executive functioning based on the type of child maltreatment experienced.

Method

This study employed a quantitative, …

Individual Differences In Lifestyle Factors And The Effects Of Acute Exercise On Executive Functioning In Children And Youth With Adhd, Jasmyn Skinner

Electronic Thesis and Dissertation Repository

Acute exercise interventions can improve executive functioning among children and youth with ADHD, however not all individuals experience the same benefit. We focused on three lifestyle factors (medication use, physical fitness, and physical activity behaviours) and their impact on the relationship between acute exercise and executive functioning. Participants completed a battery of executive functioning measures, followed by a 10-minute bout of moderate-intensity stationary biking (experimental condition), or silent reading (control condition). The same battery of assessments was re-administered immediately after the intervention and after a 10-minute delay. Overall, regardless of medication status, physical fitness level, or physical activity behaviours, an …

Understanding The Effects Of Physical Activity On Executive Functioning And Psycho-Emotional Well-Being In Children With Adhd, Hannah B. Bigelow

Electronic Thesis and Dissertation Repository

A short bout of physical activity has been shown to improve executive functioning in children. However, the implications for children with Attention Deficit Hyperactivity Disorder (ADHD) has been understudied. We examined the impact of a 10min bout of physical activity on executive functioning and psycho-emotional well-being in children with ADHD. Participants engaged in two lab-based sessions separated by 1-week: a physical activity session and a control session. The physical activity session included a 10min bout of moderate-intensity biking, with a pre-post battery of cognitive and psycho-emotional assessments. The control session consisted of 10mins of silent reading. We used functional imaging …

Preschool Self-Regulation: A Predictor Of School Readiness, Romin Emmanuel Geiger

Masters Theses & Specialist Projects

Substantial evidence from previous research has supported the idea that greater self-regulation in the form of “cool” self-regulation or executive functioning and “hot” self-regulation or effortful control is associated with higher academic achievement within the preschool years and school readiness in the kindergarten years (Anaya, 2016; Carlson, 2005). However, there are only a few studies that assess the prediction of school readiness through validated cool and hot self-regulation tasks (Carlson, 2005; Krain, Wilson, Arbuckle, Kastellanos, & Wilham, 2006; Rothbart, Ellis, Rueda, & Posner, 2003; Thompson & Giedd, 2000). There also few studies examining to what extent cool and hot-self-regulation tasks …

Exploring The Relationships Among Executive Functioning, Behaviour, And Adaptive Skills In Young Children, Melissa Read

Electronic Thesis and Dissertation Repository

This study aimed to investigate the relationships among executive functions (EFs), adaptive skills, and behaviour problems in young children. Participants were divided into four behaviour groups: high internalizing (INT), high externalizing (EXT), combined high internalizing and externalizing (COMB), and within the normal range (NORM). The predictive ability of inhibition, shift, working memory, adaptive skills, age, and gender on group membership was explored using regression analyses. A person-oriented perspective was also explored using cluster analysis. Fifty-five kindergarten and Grade one educators in Ontario, Canada completed the Behaviour Rating Inventory for Executive Functioning (second or preschool edition) and the Behaviour Assessment System …

Executive Functions As Moderators Of Response To Behavioral Interventions For Adolescents With Attention-Deficit/Hyperactivity Disorder, Stephen J. Molitor

Theses and Dissertations

Adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD) experience significant academic impairment and multiple interventions have been developed to address common academic problems, such as difficulties with homework, organization, and planning skills. Given cost and resource constraints, research is needed on factors that mental health providers can use to select the most appropriate interventions. To date, there has been minimal research evaluating moderators of response to ADHD interventions. Further, many of the variables that have been studied do not have strong theoretical ties to the mechanisms of change invoked by the interventions. This study examined potential moderators of treatment response to two academic …
