Description
It is commonly known that the left hemisphere of the brain is more efficient in the processing of verbal information, compared to the right hemisphere. One proposal suggests that hemispheric asymmetries in verbal processing are due in part to the efficient use of top-down mechanisms by the left hemisphere. Most evidence for this comes from hemispheric semantic priming, though fewer studies have investigated verbal memory in the cerebral hemispheres. The goal of the current investigations is to examine how top-down mechanisms influence hemispheric asymmetries in verbal memory, and determine the specific nature of hypothesized top-down mechanisms. Five experiments were conducted to explore the influence of top-down mechanisms on hemispheric asymmetries in verbal memory. Experiments 1 and 2 used item-method directed forgetting to examine maintenance and inhibition mechanisms. In Experiment 1, participants were cued to remember or forget certain words, and cues were presented simultaneously or after the presentation of target words. In Experiment 2, participants were cued again to remember or forget words, but each word was repeated once or four times. Experiments 3 and 4 examined the influence of cognitive load on hemispheric asymmetries in true and false memory. In Experiment 3, cognitive load was imposed during memory encoding, while in Experiment 4, cognitive load was imposed during memory retrieval. Finally, Experiment 5 investigated the association between controlled processing in hemispheric semantic priming, and top-down mechanisms used for hemispheric verbal memory. Across all experiments, divided visual field presentation was used to probe verbal memory in the cerebral hemispheres. Results from all experiments revealed several important findings. First, top-down mechanisms used by the LH primarily used to facilitate verbal processing, but also operate in a domain general manner in the face of increasing processing demands. Second, evidence indicates that the RH uses top-down mechanisms minimally, and processes verbal information in a more bottom-up manner. These data help clarify the nature of top-down mechanisms used in hemispheric memory and language processing, and build upon current theories that attempt to explain hemispheric asymmetries in language processing.

Description
The increase of Traumatic Brain Injury (TBI) cases in recent war history has increased the urgency of research regarding how veterans are affected by TBIs. The purpose of this study was to evaluate the effects of TBI on speech recognition in noise. The AzBio Sentence Test was completed for signal-to-noise ratios (S/N) from -10 dB to +15 dB for a control group of ten participants and one US military veteran with history of service-connected TBI. All participants had normal hearing sensitivity defined as thresholds of 20 dB or better at frequencies from 250-8000 Hz in addition to having tympanograms within normal limits. Comparison of the data collected on the control group versus the veteran suggested that the veteran performed worse than the majority of the control group on the AzBio Sentence Test. Further research with more participants would be beneficial to our understanding of how veterans with TBI perform on speech recognition tests in the presence of background noise.

Description
Memory Wipe is a 22 minute, video art piece that utilizes home movie footage filmed on VHS and 8mm, as well as television and cartoon ephemera, to explore the way in which personal memory is constructed and altered through the process of recording and viewing. Three recent events in my life inspired work: the discovery of a box containing my favorite childhood media, the revelation that I am the last male of my family, and the impending sale of my family's farmland. My mother never used a video camera, insisting that her childhood was lost in footage filmed but never watched. It should also be noted that not once do I appear in this piece; therefore, I decided to extract myself from the narrative. Rather than simply guide the audience along with anecdotes from my life, I instead invite viewers to draw their own meanings and create their own nostalgias from the piece. Originally, Memory Wipe was to be accompanied by live narration, but all things considered, I thought I would let it speak for itself. Video link: https://www.youtube.com/watch?v=-E42a6Koma4

Description
Since Dylan Roof, a white supremacist, shot and killed nine members of a black church in Charleston on June 17, 2015, Confederate symbols have stood at the center of much controversy across the United States. Although the Confederate battle flag remains the most obvious example, the debate took a particular form in Tennessee, centering on the image of General Nathan Bedford Forrest. Born in 1822 to a poor family, he left school early to work. Although his work in the slave trade made him a millionaire, his later participation in the massacre of over 300 black soldiers at Fort Pillow in 1864 during the Civil War and association with the Ku Klux Klan cemented his reputation as a violent racist. Yet, many white Tennesseans praised him as a hero and memorialized him. This thesis examines Nathan Bedford Forrest State Park in Benton County and Forrest Park, now Health Sciences Park, in Memphis to examine what characteristics denote a controversial memorial. Specifically, I focus on the physical form, the location, and the demographics of the area, investigating how these components work together to give rise to controversy or acceptance of the memorial's image. Physical representations greatly impact the ideas associated with the memorial while racial demographics affect whether or not Forrest's representation as a hero speaks true to modern interpretations and opinions.

Description
This study was conducted in order to create a brief task that more efficiently studies the memory of young and old dogs compared to previous dog radial arm mazes. The hypotheses were older dogs would perform worse than younger dogs, brief tasks with longer delays and the presence of an occluder would produce worse results, and the brief task with the longest delay period without an occluder would be most correlated to the radial arm maze. 45 dogs were tested from a previous sample that had participated in a radial arm maze experiment. The dogs were tested in their owner's homes and watched the researcher place a treat behind one of two boxes. Dogs then waited during different delay periods, of 15, 30, or 45 seconds, and with or without an occluder, which was a curtain. Then, the dog was released to see if it could still remember which box the treat was behind. The results supported all the hypotheses, except the 45-second brief task with an occluder was most correlated the radial arm maze. Additionally, the dogs that had to be excluded from the radial arm maze still had a similar range of results on the brief tasks as dogs that were able to complete the radial arm maze. These results confirm the radial arm maze is very difficult and strenuous on dogs, but the brief task is correlated and probably much more effective at studying memory without these issues. This study can help researchers perfect this simple task in order to study many dogs much quicker and collect more information on dogs' memory. Future studies could overcome limitations including dogs that were not motivated by treats or that were too old to stand up. Specific breeds could be tested or longitudinal studies could be conducted to find differences in memory over time. In the future, this can hopefully relate to human cognitive decline knowledge, as dogs show similar cognitive decline to humans, and help find treatments for cognitive diseases.

Description
The Soviet Union suffered immensely as a result of World War II. When the dust settled and Soviet citizens began to rebuild their lives, the memory of the social, economic, and human costs of the war still remained. The Soviet state sought to frame the conflict in a way that provided meaning to the chaos that so drastically shaped the lives of its citizens. Film was one such way. Film, heavily censored until the Gorbachev period, provided the state with an easily malleable and distributable means of sharing official history and official memory. However, as time went on, film began to blur the lines between official memory and real history, providing opportunities for directors to create stories that challenged the regime's official war mythology. This project examines seven Soviet war films (The Fall of Berlin (1949), The Cranes are Flying (1957), Ballad of a Soldier (1959), Ivan's Childhood (1962), Liberation (1970-1971), The Ascent (1977), and Come and See (1985)) in the context of the regimes under which they were released. I examine the themes present within these films, comparing and contrasting them across multiple generations of Soviet post-war memory.

Description
Women. War. What is the relationship between women and war? As evidenced by movies, popular memoirs and journals, there is a definite relationship between men and war. However, this definite relationship has created a problematic and a complex relationship between women and war. The two historical events that are considered as the ‘turning points’ for women are the French Revolution and World War I are compared in this thesis. The popular perception of women’s legacy of the French Revolution is that the Revolution cultivated the ideas of Republican Motherhood and the Cult of Domesticity while World War I catapulted women to the public sphere. These two contrasting legacies are compared to see if French women’s lived experiences, memories, and writings verify these popular perceptions. Or, do the writings of the French women present a different argument? The thesis compares the writings and the lived experiences of the French women through three different themes: the argument for political rights, victimization and agency, and gendered connections (the development of sisterhood for the Revolution) or gendered divides (women’s role on the home and war front). In addition, these three themes come together to show how it is difficult to come up with a collective, public memory.

Description
It has been suggested that directed forgetting (DF) in the item-method paradigm results from selective rehearsal of R items and passive decay of F items. However, recent evidence suggested that the passive decay explanation is insufficient. The current experiments examined two theories of DF that assume an active forgetting process: (1) attentional inhibition and (2) tagging and selective search (TSS). Across three experiments, the central tenets of these theories were evaluated. Experiment 1 included encoding manipulations in an attempt to distinguish between these competing theories, but the results were inconclusive. Experiments 2 and 3 examined the theories separately. The results from Experiment 2 supported a representation suppression account of attentional inhibition, while the evidence from Experiment 3 suggested that TSS was not a viable mechanism for DF. Overall, the results provide additional evidence that forgetting is due to an active process, and suggest this process may act to suppress the representations of F items.

Description
Music and emotions have been studied frequently in the past as well as music and memory. However, these three items don’t have as much research grouped together. Further, this research does not also encompass culture. In my research, the aim was to examine the relationship between music, memory, emotion, and culture of gender. The hypothesis was that women had more emotions linked to music than men. We gave 416 students an animal fluency task, a letter fluency task, six cultural fluency tasks, and a cultural identity survey. We used a t-test and created a graph to analyze my data. After administering my tasks, we found that women had recalled more adjectives linked to music than men. However, there was not a statistically significant difference between the number of adjectives with emotional valence between men and women, indicating that there was no relationship between gender and emotion in regards to music. The limitations on this study included the descriptions on how to complete the task, the cultural norms of the participants, and the disparity between the number of female and male participants. In a future study, it is necessary to be more specific in what is desired from the participants and to pay close attention to shifting gender norms. Further, we would also like to see how the results from future research can impact music therapy for memory-related mood disorders.
