The language system in the human brain. ABSTRACT: The goal of my research program is to understand the representations and computations that enable us to share complex thoughts with one another via language, and their neural implementation. A decade ago, I developed a robust new approach to the study of language in the brain based on identifying […]
Dog, cat, and leash: Difference in processing costs among inflectional allomorphs during speech production. Abstract: We need to generate contextually-appropriate inflections to produce well-formed words and sentences, and a key component of this process is generating the correct allomorph – variant pronunciations of a morpheme. In this project, we examine the processing costs of the English regular […]
Current MA student Atlas Kazemian will give a talk on "Toward a computational neuroscience of visual cortex without deep learning."
Modeling shared and variable information encoded in fine-scale cortical topographies. ABSTRACT: Information is encoded in fine-scale functional topographies that vary from brain to brain. Hyperalignment models information that is shared across brain in a high-dimensional common information space. Hyperalignment transformations project idiosyncratic individual topographies into the common model information space. These transformations contain topographic basis functions, affording […]
How much do we know about visual representations? Quantifying the dimensionality gap between DNNs and visual cortex'. Abstract: Deep neural networks (DNNs) can explain a large portion of variance in image-evoked cortical responses by accounting for the highest variance latent dimensions in neural data, such as dimensions corresponding to animacy, aspect ratio, and curvature. However, […]
Six Dimensions of Dance Cognition. ABSTRACT: There is a growing body of work in philosophy, cognitive science, and neuroscience that tries to better understand the mind by examining it in the context of dance. Such work is often premised on the idea that dance demonstrates important, general, and underappreciated features of human thought. However, existing […]
Learning words in a bilingual world. ABSTRACT: In the U.S., 1/3 of children hear a language other than English in the home and have the opportunity for bilingual language development. Yet, the mechanisms behind word learning across two languages have not been clearly outlined. In this talk, I will present two lines of work focused […]
Prof. Daniel Dilks is an associate professor of psychology at Emory University. His research focuses on three big questions about human vision: i) How is the visual cortex functionally organized?, ii) How does this functional organization get wired up in development?, and iii) Once wired up, how does visual cortex change in adulthood? Talk topic […]
This 2-day event will include speakers. Details will be posted here. Registration required.
This event will be offered in-person and synchronously online. The nature of mid-level representations in visual processing inferred from the study of a woman with a highly specific developmental visual disorder. ABSTRACT: Although all objects around us shift and turn on our retinas when we move or turn our head, phenomenologically they remain in the […]
Sociophonetic Variation and Human Interaction with Digital Voice Assistants. This event will be offered in-person and online. Those who wish to attend in-person must fill out this brief RSVP form so we can remain compliant with JHU’s covid crowd limits. As technology that relies on speech is increasingly integrated into modern American society, voice assistants are becoming […]
*Hybrid event; in-person attendance requires RSVP* Developing behavioral flexibility. Throughout our lives, we rapidly acquire knowledge through experience. This knowledge is structured — it reflects regularities in our environments...
