Individual Differences In Categorization, Urooj Anees

Undergraduate Student Research Internships Conference

The appearance of individual differences used to be regarded as noise in psychological experiments, but is slowly becoming a tool used to enhance and solidify findings in various fields of cognitive psychology. This presentation aims to very briefly discuss individual differences and categorization and what questions future research could aim to answer.

Changes In Audiovisual Integration In Aging, Alyssa S. Lynn

Undergraduate Student Research Internships Conference

The proposed study will examine changes in audiovisual integration between younger and older adults. Audiovisual integration enables us to associate and bind related auditory and visual information and experience it as a single percept (Spence, 2007). Being able to properly integrate is crucial in our everyday lives. When perceiving speech, audiovisual integration binds visual information from lip movements with auditory information from the speaker's utterances so that speech can be perceived multimodally. With age, our auditory and visual sensory acuity tends to decline with audiovisual integration being impacted as a result (Brooks et al., 2018; Mahoney et al., 2011). We …

The Ommaba Project, Katsiaryna Buchko

Undergraduate Student Research Internships Conference

The Open Multimodal Music and Auditory Brain Archive (OMMABA) is the first multimodal (behavioural, EEG, and neuroimaging) database characterizing normal human auditory processing. My project aims to shed light on the importance of this collaborative project that is transforming the field of auditory cognitive neuroscience.

Motor Learning By Observing The Movements Of A Computer-Animated, Human-Like Actor And A Non-Limb Observational Video, Mudia Iyayi

Undergraduate Student Research Internships Conference

Our project is looking at the phenomenon of observational motor learning using a two-joint robotic manipulandum (robotic arm). When someone learns a new motor skill (i.e. throwing a football to a wide receiver) the brain must make and map an internal model of the forces required for that movement. The plasticity of the brain in constructing these representations is termed “motor learning” and can occur through physical practice or—for the purposes of our investigation—observation. Previous studies have used videos of human actors learning new skills to drive motor learning in the observer, however, it is not known what components of …

Auditory Sensory Filtering And Development In Children With Autism Spectrum Disorder, Hiruthika Ravi, Ala Seif, Ryan A. Stevenson

Undergraduate Student Research Internships Conference

Sensory filtering is the process of separating and distilling relevant sensory information from irrelevant, which in turn greatly reduces the quantity of sensory information that is fully processed and leads to significant increases in efficiency. Atypical sensory filtering can result in sensory hypo- or hypersensitivity — atypical sensory filtering and hypo/hypersensitivity have been observed in people with autism. Atypical sensory filtering contributes to canonical symptoms in Autism.

Sensory filtering can be measured in a few different ways, one of which is the Acoustic Startle Response (ASR). ASR is a reflexively produced muscular reaction to sudden auditory stimuli.

Our study aims …

Visual Expertise In An Anatomically-Inspired Model Of The Visual System, Garrison W. Cottrell, Martha Gahl, Shubham Kulkarni

MODVIS Workshop

We report on preliminary results of an anatomically-inspired deep learning model of the visual system and its role in explaining the face inversion effect. Contrary to the generally accepted wisdom, our hypothesis is that the face inversion effect can be accounted for by the representation in V1 combined with the reliance on the configuration of features due to face expertise. We take two features of the primate visual system into account: 1) The foveated retina; and 2) The log-polar mapping from retina to V1. We simulate acquisition of faces, etc., by gradually increasing the number of identities the network learns. …

Cognitive Insights And Implications Of Singing: Actions, Proprioception, And Perception In Vocal Performance., Juanita Leal

Graduate Student Research Symposium

Studies in vocal performance have suggested the interdependence of cognitive reactions and performative proprioception. This interdependence indicates an introspective self-evaluation process during the act of musical performance. When affected by singers’ judgment of vocal production, self-evaluation and perceptive processes potentially change due to implicit competitive roles in the music performance environment.

In this project, I delve deeper into the ways the brain recognizes aspects of vocal sounds, how it reacts to the process of singing, and how it can identify them as its own In two different environments: the controlled practice space and the variable performance space. By reflecting on …

The Program To Reduce Implicit Bias In Carroll Hospital Center Using The Implicit Association Test, Katherine E. Traynor

Capstone Showcase

Natural brain processes make all individuals susceptible to unconscious bias; however, stressful, fearful, or anger-evoking situations as well as the negative influence of media and social surroundings increase the risk of holding obstructive bias, and there is a greater risk of being negatively impacted by this phenomenon when belonging to a minority population (Rose & Flores, 2020). As a result, high rates of infant mortality (10.2 deaths per 1,000 live births for the Non-Hispanic Black population compared to 4.1 in the White population) and cardiovascular related diseases (190.0 cases per 1,000 in the Non-Hispanic Black population compared to 161.3 in …
