The Human Language and Development Laboratory is an interdisciplinary research lab at the New School for Social Research dedicated to the study of human linguistic and nonlinguistic communication from infancy through adulthood. It is directed by Ruthe Foushee, in the Department of Psychology.

The lab integrates evidence from a range of empirical methodologies (including eyetracking; behavioral experiments conducted in the laboratory, classroom, online, and in the field; analyses of naturalistic behavior and spontaneous language use; and qualitative interviews and survey data), with a focus on approaches that are at once ecologically valid and quantitatively rigorous.

Our research is informed by work in semantics, sociolinguistics, linguistic anthropology, philosophy of language, cognitive development, and machine learning.
