The War That Does Not Leave Us: Memory Of The American Civil War And The Photographs Of Alexander Gardner, Katie Janae White Jun 2014

The War That Does Not Leave Us: Memory Of The American Civil War And The Photographs Of Alexander Gardner, Katie Janae White

Theses and Dissertations

In July of 1863 the photographs A Harvest of Death, Field Where General Reynolds Fell, A Sharpshooter's Last Sleep, and The Home of a Rebel Sharpshooter were taken after the battle at Gettysburg by a team of photographers led by Alexander Gardner. In the decades that followed these images of the dead of the battlefield became some of the most iconic representations of the American Civil War. Today, Gardner's Gettysburg photographs can be found in almost every contemporary history text, documentary, or collection of images from the war, yet their journey to this iconic status has been little discussed.

The Effect Of Sleep-Dependent Consolidation On Pattern Separation And Pattern Completion In Delayed Retrieval, Jesse Ray James Feb 2014

The Effect Of Sleep-Dependent Consolidation On Pattern Separation And Pattern Completion In Delayed Retrieval, Jesse Ray James

Theses and Dissertations

While people sleep, the brain replays the same neural firings that resulted from waking activities that day. This results in greater memory strength following a sleeping delay than a waking delay. The current project built upon this fact in a series of three experiments. Experiment 1. Although previous research has demonstrated a benefit of sleep to memory strength, the literature has not established the impact of sleep on memory specificity. Computational models of medial temporal lobe function posit that discrimination and generalization across similar memories are accomplished through processes known as pattern separation and pattern completion, respectively. To discover whether …
