Developmental Differences In The Learning And Consolidation Of Linguistic Regularities, Sarah Berger
Developmental Differences In The Learning And Consolidation Of Linguistic Regularities, Sarah Berger
Electronic Thesis and Dissertation Repository
Relative to adults, children have a well-known advantage for learning linguistic regularities, which could be partially driven by their deeper sleep. To examine the relationship between consolidation and language learning across development, children and adults learned a novel article system with an implicit grammatical rule. Participants performed a judgment task on phrases containing the novel articles before and after a night of EEG-monitored sleep. We found that rule sensitivity emerged rapidly in children, whereas it did not emerge until the second session in adults. Children demonstrated better generalization of the rule than adults. Consolidation effects showed a developmental double dissociation, …
The Relationship Between Neighbourhood-Level And Family-Level Factors And Sleep Problems Among Children And Youth, Katarina Mckenzie
The Relationship Between Neighbourhood-Level And Family-Level Factors And Sleep Problems Among Children And Youth, Katarina Mckenzie
Electronic Thesis and Dissertation Repository
There is little research on the effects of neighbourhood factors on child sleep outcomes. No study to date has investigated the interactive effects of neighbourhood and family socio-economic characteristics (SECs) on child sleep outcomes. This study aimed to fill this gap. Secondary data analyses were completed on two samples (children and youth) from the 2014 Ontario Child Health Study, a cross-sectional, province-wide sample of 10,802 children aged 4 to 17. Multi-level modeling was used to assess the relationship between child- (e.g., age), family- (e.g., negative parenting) and neighbourhood-level factors and their relationship to sleep outcome variables: problems falling asleep, problems …
Conscious Perception And Implicit Memory Formation Of A Narrative Presented During Sleep, Sarah E. Hollywood
Conscious Perception And Implicit Memory Formation Of A Narrative Presented During Sleep, Sarah E. Hollywood
Electronic Thesis and Dissertation Repository
The present study sought to determine the extent of conscious awareness and implicit memory formation of a narrative presented during sleep. Participants were played an excerpt of J.D. Salinger’s Pretty Mouth and Green My Eyes while napping. Afterwards, participants completed a task designed to assess implicit memory to determine if they had formed any memories about words that were either directly stated in the story, or directly related to the plot. Participants who heard the story while asleep responded more quickly to words that had appeared in the story than to words from another story they had not heard. Exactly …
Child And Adolescent Sleep Disturbances And Psychopathology In A Mental Health Clinic Sample, Aviva Blacher
Child And Adolescent Sleep Disturbances And Psychopathology In A Mental Health Clinic Sample, Aviva Blacher
Electronic Thesis and Dissertation Repository
Sleep disturbances in children and adolescents (hereafter children) are associated with significant short-term and long-term impairments including more severe psychopathology, reduced cognitive functioning, and poorer general health. We know that children being treated in specialty mental health services are more likely to have sleep disturbances than community samples. We also know that relationships exist between sleep and psychopathology in children with specific disorders (e.g. ADHD, depression, etc.). However, few studies have investigated the relationship between sleep and psychopathology in a broad sample of children seen at mental health agencies. Both child factors and family factors may influence both sleep and …
Parental Help-Seeking For Pediatric Insomnia: Where, When, And Why Do Parents Seek Help?, Adam T. Newton
Parental Help-Seeking For Pediatric Insomnia: Where, When, And Why Do Parents Seek Help?, Adam T. Newton
Electronic Thesis and Dissertation Repository
Pediatric insomnia affects approximately 25% of children and can impact both child and parent functioning. Despite its prevalence and impact, next-to-nothing is known about help-seeking mechanism for pediatric insomnia. These mechanisms are expected to mirror models from the children’s mental health help-seeking literature. Both studies in this thesis gathered data from an online multinational project. Manuscript 1 investigated the informal, informational, and formal sources of help for pediatric insomnia and the factors that motivated parents to seek professional help. Parents utilized or expected to utilize a variety of informal (most commonly their partner, friends, or family members) and informational (most …
Does Sleep Enhance The Consolidation Of Implicitly Learned Visuo-Motor Sequence Learning?, Jeremy Viczko
Does Sleep Enhance The Consolidation Of Implicitly Learned Visuo-Motor Sequence Learning?, Jeremy Viczko
Electronic Thesis and Dissertation Repository
Sleep has been shown to facilitate the consolidation (i.e., enhancement) of simple explicit (i.e., conscious) motor sequence learning (MSL). It remains unclear the degree to which this applies to implicit (i.e., unconscious) MSL. Employing reaction time and response generation tasks, we investigated the extent to which sleep is involved in consolidating implicit MSL, specifically whether the motor or the spatial cognitive representations of a learned sequence are enhanced by sleep, and whether these changes support the development of explicit sequence knowledge across sleep but not wake. Our results indicate that spatial and motor representations can be behaviourally dissociated for implicit …
Dancing In The Dark: Sleep-Dependent Motor Skill Memory Consolidation And Periodic Limb Movement Disorder, Valya Sergeeva
Dancing In The Dark: Sleep-Dependent Motor Skill Memory Consolidation And Periodic Limb Movement Disorder, Valya Sergeeva
Electronic Thesis and Dissertation Repository
Periodic Limb Movement Disorder (PLMD) is a neurodegenerative disease characterized by dysfunction of the striatum and brief, repetitive limb movements during sleep. PLMD can severely disrupt non-rapid eye movement (NREM) sleep. Motor skills learning and memory consolidation are dependent on striatal activation, the latter enhanced by NREM sleep. Therefore, we investigated whether individuals with PLMD had learning and sleep-related memory deficits, and whether this putative deficit was related to sleep quality or symptom severity. 14 adults with a PLM index >15/hr underwent two nights (baseline, training) of polysomnographic recording. 15 age-matched healthy controls underwent three nights (baseline, undisturbed training and …
Parenting At Midnight: Measuring Parents' Thoughts And Strategies To Help Young Children Sleep Through The Night, Aimee J. Coulombe
Parenting At Midnight: Measuring Parents' Thoughts And Strategies To Help Young Children Sleep Through The Night, Aimee J. Coulombe
Electronic Thesis and Dissertation Repository
Throughout the night, brief periods of arousal are common and not necessarily indicative of problematic sleep. Awakening without an easy return to sleep (“night-waking”), however, can be problematic for parents and children alike. Approximately 30% of preschool-aged children wake at least once per night and require parental intervention (“help or assistance”). Although parents’ responses to children’s night-waking (i.e., parents’ night-waking strategies) can determine the course of night-waking over time, very little is known about night-waking strategy use among parents of preschool-aged children. The purpose of the present dissertation was to lay the foundation upon which a better understanding of the …
