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, …
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 …

Formation Of Implicit Memories From A Narrative Played During Sleep, Amanat Ludhar
Undergraduate Honors Theses
Though, it was previously thought that the sleeping brain was dormant, research suggests that participants can process salient stimuli and form implicit memories of simple stimuli (e.g. words) during sleep. Thus, the current study aimed to determine whether participants could form implicit memories of a narrative played during sleep, and what role different sleep stages played in this memory formation. Participants were played a story while taking a nap, and EEG was used to track time spent in different sleep stages. Later, participants completed an implicit memory task where they were asked to differentiate between animal and non-animal words through …
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 …
