Welcome from Lab Director, Prof. Patricia Greenfield

Our research explores how values, behavior and cognition are shaped by social change. Our current studies in Mexico, China, and Israel investigate human development within a changing social ecology that include variables such as urbanization, education and commercialization.

For information on our studies of the implications of technology for human development, please go to cdmc.ucla.edu. For information on our work on the implications of social change for cognitive development, learning, and textile design in a Maya community in Chiapas, Mexico, please go to weaving-generations.psych.ucla.edu

For earlier research on evolution and primate studies, language acquisition, cultural studies, grammars of action, and neuroscience, please go to the publication page.
