Research Output For Usri, Malak Sadek

Undergraduate Student Research Internships Conference

My project is a systematic review on Neural Representations of Stimulus Category Membership Across Modalities.The review is about neural evidence for categorical perception (equivalently, dimensional modulation, perceptual warping, or representational change) induced by artificial category learning.

Osteoarthritis In Early To Middle Epipalaeolithic, Aasiyah Sheri Ms

Undergraduate Student Research Internships Conference

The study of human remains allows insight into the past. Studying an individual's bones and any diseases or abnormalities that may present themselves allows archaeologists to construct an image of what life might have been like for the individual. How old they were when they died, the type of work they did, and their overall health are all factors that can tell us a great deal about a person.

Characteristics Of Those Who Identify As ‘Incels’, Amelia Hamilton

Undergraduate Student Research Internships Conference

‘Incels’ are an online community of single men who endorse toxic worldviews about women stemming from their dissatisfaction with singlehood. Approximately 50 deaths have been tied to the incel community. Incels have been identified as an emerging domestic terrorism threat in Canada, the US and UK. Yet, little is known about the characteristics of this community, the potential level of threat, or what we can do to prevent this threat from escalating. In an online study of 1714 single individuals, we examined what personality traits are associated with one’s identification as an incel. Participants completed a survey consisting of various …

The Effect Of Leverage On Credit Default Swaps, Xiling Lai

Undergraduate Student Research Internships Conference

The research investigates the effect of leverage on the pricing of Credit Default Swaps (CDS) and focuses on key sectors of the economy: Technology, Financials, Consumer Staples and Industrials. CDS are financial instruments that were developed a few decades ago and have become more widely used in financial markets for hedging credit exposures. Given their prevalence in financial markets, it is important to understand how CDS spreads change when reference entities modify their capital structure.

In the regression analysis, the level of CDS spread is used as dependent variable, and the standardized relative leverage is used as independent variable. My …

Category Learning - Studies In Mood Induction And Neural Representations Across Modalities, Raha Afkhami Nemati

Undergraduate Student Research Internships Conference

In this powerpoint presentation, I discuss the two projects I worked on this summer: study focusing on how mood induction impacts categorization and a systematic review on stimulus categories across modalities. Throughout the presentation, I show the work I have done this past year, this summer and what I plan to continue with over the year. I discuss the papers, applications and criteria used throughout.

The Effect Of Dopamine On The Behavioral Response To Isolation In Drosophila Melanogaster, Micah R. Evans

Undergraduate Student Research Internships Conference

Social behavior is exhibited based on a response to other individuals and involves the integration of external cues from surrounding organisms. A complete lack of interaction with others can profoundly affect social behavior in a variety of species. An example of the effect of social isolation can be seen in the fruit fly (Drosophila melanogaster) when observing the social behavior of social space, which is the preferred distance between neighbours. Isolated flies have increased social space and settle further apart from one another compared to flies that are group-housed.

What modulates this behavioral response to the social environment in fruit …

An Analysis Of Ground Stone Celts On The Late Woodland Middle Ontario Iroquoian Dorchester Village Site (Afhg-24), Patrick J. Seddon

Undergraduate Student Research Internships Conference

A comprehensive analysis of ground stone celts on the Late Woodland Middle Ontario Iroquoian Dorchester Village Site (AfHg-24). Metric and non-metric traits of the celts were analyzed to gain a better understanding of ground stone tools and their uses. A greater understanding of site formation processes and the development of Late Woodland Iroquoian villages may be attained through the creation of typologies, and an analysis of tool metrics, manufacturing and use wear traits, non-chert detritus produced through manufacture, and intra-site spatial data.

Simulating Salience: Developing A Model Of Choice In The Visual Coordination Game, Adib Sedig

Undergraduate Student Research Internships Conference

This project is primarily inspired by three papers: Colin Camerer and Xiaomin Li’s (2019 working paper)—Using Visual Salience in Empirical Game Theory, Ryan Oprea’s (2020)—What Makes a Rule Complex?, and Caplin et. al.’s (2011)—Search and Satisficing. Over the summer, I worked towards constructing a model of choice for the visual coordination game that can model player behavior more accurately than traditional game theoretic predictions. It attempts to do so by incorporating a degree of bias towards salience into a cellular automaton search algorithm and utilizing it alongside a sequential search mechanism of satisficing. This …

The Differences Between Visual And Auditory Pattern Separation, Alvira Khurram

Undergraduate Student Research Internships Conference

• There has been limited investigation into pattern separation in modalities other than the visual domain, specifically little study of auditory pattern separation.

• Research on developing a measure of auditory pattern separation can aid in growing our understanding of memory and encourage further research of pattern separation in the auditory domain.

• Using Stark’s visual MST and an auditory MST (created by Helena Wang) the differences in performance of participants across the tasks was compared.

• The performance of the visual MST group was found to be not significantly different from the performance of the auditory MST group, as …
