Principal Investigator


Prof. Lauren Emberson
Lauren is broadly interested in how experience shapes development and studies this process through the lens of perceptual and learning abilities. How do these abilities interact and fuel developmental changes? Lauren is also the co-founder and co-director of the Princeton Baby Lab.

Post-Doctoral Researchers

Sagi_Jaffe-Dax_photoDr. Sagi Jaffe-Dax
Sagi is interested in how infants learn to predict upcoming events and perceive them efficiently. To reveal the underlying mechanism of these processes, Sagi uses both behavioral, computational and neuro-imaging approaches.

Dr. Gabriel (Naiqi)  Xiao
Gabriel’s studies focus on how learning capabilities interact with perception in newborns and infants. To answer related research questions, he uses various research techniques, such as behavioral measurements, eye-tracking, and neuroimaging. Gabriel received his doctorate degree from the University of Toronto (Canada) in 2016, where he spent years to understand face perception in infants across the world and to develop a novel eye movement data analysis toolbox (iTemplate).

Graduate Students

IMG_8181Felicia Zhang
Hi! I’m a fourth year graduate student in the Baby Lab. I research how young infants use prediction error (i.e. wrong predictions) to learn information from the world. My research uses eye-tracking, with a specific focus on pupillometry (i.e. the measurement of pupil size) with computational modelling.

Tracy Reuter
My research investigates language processing, prediction, and learning. Given the incredible complexity of language, how do we finish each other’s… sandwiches? (And what happens when our predictions are wrong?)

Sori received her B.S. in Psychology in University of Minnesota. Sori is excited to use fNIRS to investigate the mechanisms through which babies use their experiences to engage in top-down processing on visual perception. She is most interested in exploring functional connectivity in the infant brain to understand the inception and early development of complex functional networks.             Personal Website


Senior Thesis Students

AliceWangAlice Wang
Alice Wang (Class of 2019), from Palo Alto, California, is currently concentrating in psychology with a visual arts certificate. She is interested in the role education plays in child development, specifically regarding how visual and acoustic stimuli influence learning. In her spare time, Alice can be found (break)dancing with Sympoh, writing old-fashioned letters, or naming inanimate objects.


fernandaFernanda FernandezVV
Fernanda Fernandez (Class of 2019) is a Neuroscience major from Rutherford, New Jersey who loves taking care of and working with children. Her senior thesis research focuses on infants’ visual perception—how infants can use predictive sounds to guide their interpretation of an ambiguous picture. Outside of the lab, she is an EMT for the Princeton First Aid and Rescue Squad in town and a tutor at McGraw. In her free time, she loves going on runs, playing guitar, or spending time with friends. After Princeton, she plans to attend medical school and become a physician.

Claire received her B.A. in Psychology from Kenyon College. While at Kenyon, Claire studied conscious and unconscious face perception using EEG in the Kenyon Psychology and Neuroscience Lab under Dr. Andrew Engell. Claire is excited to contribute her psychology background and neuroscience research experience toward the study of infant development.
