Changes In Hemodynamic Response To Faces, Scenes, And Objects In A Visual Statistical Learning Task: An Fmri Analysis, Aaron T. Halvorsen
Changes In Hemodynamic Response To Faces, Scenes, And Objects In A Visual Statistical Learning Task: An Fmri Analysis, Aaron T. Halvorsen
Honors Theses
Learning causes changes in brain activity and neural connections. Statistical learning is an implicit learning process that involves extracting regularities from the environment and finding patterns in stimuli based on their transitional probabilities. The following study describes an attempt to elucidate temporal changes in hemodynamic activity for three category-specific brain areas using functional magnetic resonance imaging (fMRI). Blood oxygen-level dependent signal (BOLD) responses were collected while subjects viewed faces, scenes, and objects with high and low transitional probabilities in an fMRI scanner. We expected brain activity to show a temporal shift in timing of activation when comparing BOLD signal responses …
The Effects Of L. Rhamnosus Consumption On Male Long Evans Rat Anxiety-Like Behavior, Amanda Marie Schleper
The Effects Of L. Rhamnosus Consumption On Male Long Evans Rat Anxiety-Like Behavior, Amanda Marie Schleper
Honors Theses
Adolescent stress in humans has been correlated with an increased likelihood of an individual to develop an alcohol use disorder later in life. Literature has demonstrated that rats subjected to adolescent stress tend to show an increased preference and consumption of ethanol. Adolescence is a critical time of development. The link between adolescent stressors and alcohol use disorders is not fully understood yet. This study examined the relationship between adolescent stress and alcohol consumption and preference in rats. Probiotics are bacteria with potential health benefits and have been well accepted as a dietary supplement. Literature shows that probiotics could decrease …
The Effects Of Retrieval Strategy On A Collaborative Reconstruction Task, Amanda M. Bullock
The Effects Of Retrieval Strategy On A Collaborative Reconstruction Task, Amanda M. Bullock
Honors Theses
The purpose of the present experiment was to explore the effects of using various retrieval strategies on a collaborative reconstruction task. More specifically, we sought to determine the extent to which the Retrieval Strategy Disruption Hypothesis (RSD) could explain the effects of collaborative inhibition on such tasks. Collaborative inhibition is observed when collaborative group performance is lower than the pooled performance of an identical number of individuals working alone (nominal groups). The RSD hypothesis suggests that one group member’s output disrupts another group member’s idiosyncratic retrieval strategy leading to poorer performance relative to individuals working alone. In the present study, …

Preparation Of A Perylenebisimide Acceptor With Serinol And Nonadecyl-Swallowtail Imides For Use In Molecular Rectification, Tarrah Frederick
Honors Theses
Several attempts were made to add 2-amino-1,3-propanediol to the acceptor perylene monoanhydride (PMA). The theoretical product, N-(10-nonadecyl)-N'-(1,3-dihydroxypropan-2-yl)perylene-3,4,9,10-bis(dicarboximide), is intended for use in unimolecular rectification because the perylenebisimide core is classified as a good acceptor due to its high electron affinity. Rectification usually utilizes donor-σ-acceptor molecules, whose localized orbitals permit electron transfer when placed between metal electrodes of asymmetric voltages. However, according to an “asymmetric rectification” analysis, an electron can pass from one electrode, through the LUMO of the acceptor, and then to the other electrode when said electrodes are held at certain voltages, and result in rectification if the acceptor …
