Principal Investigator
John Trueswell
Professor John Trueswell is a psycholinguist who studies language acquisition and language processing. Some of the fundamental questions that Professor Trueswell is interested in include: How do humans so effortlessly interpret utterances in real-time, using incoming speech to compute a speaker’s intended meaning? How do young children learn the meanings of words, and interpret syntactic structure? How do the processing demands of real-time interpretation influence language acquisition, and possibly shape the languages of the world? And conversely, does the language we speak change how we see and think about the world?

Lila Gleitman
It is with profound sadness to report that Professor Lila Gleitman passed away August 8, 2021, at age 91. Lila was a leader in the developing field of cognitive science, and a guiding light to many in the field both personally and professionally.

Postdoctoral Researchers
Martin Ho Kwan Ip
Martin is a postdoctoral fellow. He received his Ph.D. in Psychology from the MARCS Institute in December 2019. He is interested in how speech processing can be shaped by both language-universal mechanisms and our experience with our native language. At the Language Learning Lab, Martin studies (1) how infants and young children use cues from prosodic focus to learn and remember words and their contextual alternatives, and (2) how adult speakers across languages prioritize different information structural and phrasing cues in sentence disambiguation.

Tyler Knowlton
Tyler is a postdoctoral fellow. He earned his PhD in Linguistics from the University of Maryland and his BA in Cognitive Science from Johns Hopkins. His research focuses on the meanings of logical expressions like “every” and “most” and asks: What do their mental representations look like? How do the formal details of those representations affect non-linguistic cognitive systems? And what leads children to connect those particular representations with the relevant pronunciations?

Zoe Ovans
Zoe is a postdoctoral fellow. She received her Ph.D in Neuroscience & Cognitive Science from the University of Maryland and her BA in Cognitive Science and English from Johns Hopkins University. She is interested in how sentence processing interacts with extralinguistic systems, such as executive function and spatial processing. Her doctoral work focused on how our cognitive control system interacts with real-time sentence processing during development, and her postdoctoral work investigates how sentence processing interacts with spatial reasoning, as well as how children learn words and structures that express symmetrical relations.

Graduate Students
Victor Gomes
Victor is a fifth-year graduate student. He graduated from Swarthmore College in 2017 with a B.A. in cognitive science and psychology. He is interested pragmatics, expressives, negation, and how we learn the meaning of logical operators (e.g., and, or, not) more broadly. He is passionate about outreach and education, and enjoys reading about narratology and comparative mythology, but in a cool way. He is also the program coordinator for out4STEM, an afterschool program for LGBT+ teens interested in science, at the Mütter Museum.

Abigail Laver
Abby is a first-year graduate student. She graduated from the University of Pennsylvania in 2021 with a B.A. in Psychology. Her research investigates how children can use the first few words they’ve acquired to learn syntax and additional word meanings. She also does work on whether children have an abstract representation of symmetry that is shared between vision and language. In her free time, Abby enjoys reading, seeing the ballet and musicals, hiking, and spending time with friends and her dog.

Lab Manager
Heesu Yun
Heesu is the current lab manager of the Language Learning Lab. She graduated with a B.S. in Psychology from Boston College in May 2023. She has conducted research on how different linguistic structures of a first language influence the acquisition of a second language, specifically in terms of genetic, phonological, and syntactic similarities.
