Guilty By Association: Time-Dependent Memory Consolidation And The Generalization Of Person-Specific Traits To Other Group Members, Luke R. Enge
Open Access Theses & Dissertations
The following study investigated the extent to which time-dependent memory consolidation facilities the generalization of person-specific traits (individuated targets) to other, familiar social group members (familiar targets) Sixty-Nine (N = 69) participants learned to distinguish between two arbitrary groups, one positive and one negative. Participants learned the negative or positive information about a subset of the group members (individuated targets) and no individuating information about the familiar targets. Participants returned either without a time-delay containing sleep (2-6 hours after learning) or a time-delay with sleep (48 hours after learning). Results demonstrated that only after a time-delay containing sleep, negative information …

The effect of mild sleep restriction on cognitive functioning in young children is unclear, yet sleep loss may impact children's abilities to attend to tasks with high processing demands. In a preliminary investigation, six children (6.6 - 8.3 years of age) with normal sleep patterns performed three tasks: attention (“Oddball”), speech perception (conconant-vowel syllables) and executive function (Directional Stroop). Event-related potentials (ERP) responses were recorded before (Control) and following one-week of 1-hour per day of sleep restriction. Brain activity across all tasks following Sleep Restriction differed from activity during Control Sleep, indicating that minor sleep restriction impacts children's neurocognitive functioning.
Post-Traumatic Sleep Following Diffuse Traumatic Brain Injury, Rachel K. Rowe
Post-Traumatic Sleep Following Diffuse Traumatic Brain Injury, Rachel K. Rowe
Theses and Dissertations--Neuroscience
Traumatic brain injury (TBI) is a major cause of death and disability throughout the world with few pharmacological treatments available for individuals who suffer from neurological morbidities associated with TBI. Cellular and molecular pathological processes initiated at the time of injury develop into neurological impairments, with chronic sleep disorders (insomnia, hypersomnolence) being among the somatic, cognitive and emotional neurological impairments. Immediately post-injury, TBI patients report excessive daytime sleepiness, however, discordant opinions suggest that individuals should not be allowed to sleep or should be frequently awoken following brain injury. To provide adequate medical care, it is imperative to understand the role …
