Emotional judgments of individual scenes are influenced by unintentional averaging
No full textPresentation by Yavin Alwis ('20) delivered at the Rhodes College Undergraduate Research and Creative Activity Symposium (URCAS).The visual system uses ensemble perception to summarize visual input across a variety of domains. This heuristic operates at the highest levels of vision, compressing information as complex as emotion, animacy, and scene valence into an efficient representation. Previous work has shown the average size of a set can influence the perceived size of an individual item, and vice versa (Brady & Alvarez, 2011), but it has yet to be demonstrated whether such effects emerge for high-level stimuli, specifically, emotional scenes. In the current experiment, we tested whether the perceived emotional valence of a single scene could be influenced by surrounding, simultaneously presented scenes. Observers first rated the emotional valence of a series of individual scenes. Observers then saw ensembles of the original images and were cued to rerate just one of the four. We predicted the perceived emotional valence of the cued image would be pulled toward the mean emotion of the surrounding ensemble. Results confirmed this. The correlations across observers revealed that the bigger the difference between the valence of the ensemble and the valence of the cued image, the more the rating of the cued image shifted toward the average of the ensemble. We conclude that high-level ensemble information can influence how we perceive individual items in the crowd, even when that information is not directly task relevant
"The One Who Looks, Looks Upon The One Who Looks Upon The One Who Looks Upon..." exhibition image
No full textThis digital image was taken by Chip Pankey and uploaded to DLynx by the Visual Resources Center in July 2022.This is an image documenting the "The One Who Looks, Looks Upon The One Who Looks Upon The One Who Looks Upon..." exhibition, which was held in the Clough-Hanson Gallery from January 25 through March 21. This exhibition was created by "poly artists" Kuperus & Miller, who together make up Adult, as an extension of their then-upcoming album Perception as/is/of Deception. This exhibition uses built environments as well as decieving two-dimensional pieces to toy with the act of looking and the resultant, often unacknowleded, of being looked back at as well as that which goes unseen. Both artists focus on a different objective with their pieces in one singular exhibition, thus leaving the audience to discern the expected engagement with the space and message of the works
The Effects of Mitochondrial Mutation of Tumorigenesis
No full textPresentation by Danielle Healey ('20) delivered at the Rhodes College Undergraduate Research and Creative Activity Symposium (URCAS) as part of the St. Jude Summer Plus Fellowship.This paper investigated the activity of tumorigenesis within mitochondrially mutated progenitor cells. It seeks to answer how the epigenetics of mitochondrially mutated cells containing the NMyc oncogene changes the rate of tumorigenesis. The experiment investigated the changes in methylation and acetylation of the N-Myc infected progenitor cells to determine the extent that gene expression and regulation were occurring at. It focused on the differences in acetylation and methylation regarding the different genotypes in the PolG mice model (wild type, heterozygous, homozygous) containing the N-Myc gene. Immunofluorescent imaging was used to quantify the changes in acetylation and methylation of the cells and establish the degree of change in the epigenetics compared to how the cells experienced changes in tumorigenesis. Preliminary results indicated decreased tumorigenesis in the homozygous N-Myc progenitor cells compared to the wild type and heterozygous models infected with N-Myc. Studies to determine the degree of change in acetylation and methylation between genotypes are ongoing
Master's Thesis: "I'd Rather Be in Trouble Than Be Embarrassed": A Literature Review of the Relationship Between Behavior and Literacy in Urban Schools
No full textThis thesis explores the connection between literacy development and student behavior in urban elementary schools, arguing that disruptive behavior often stems from students'discomfort with their reading abilities. Using a Critical Race Theory (CRT) framework, Boyd critiques how systemic racism, poverty, and punitive school environments contribute to literacy struggles and behavioral issues among students of color. The literature review categorizes research into three areas: the historical education debt, the behavioral impact of academic struggle, and instructional strategies that address both. Boyd emphasizes that traditional classroom management often criminalizes students rather than supporting their academic and emotional needs. The study calls for culturally responsive, trauma-informed, and literacy-centered teaching practices that affirm students'identities and promote equitable learning environments
