Child Language and Speech Studies Lab 

About Us

How do children master language so quickly and seemingly effortlessly, while adults often struggle for years to simply learn to order a meal in a new language? In Dr. Elizabeth Johnson’s Child Language and Speech Studies (CLASS) Lab at the University of Toronto Mississauga (UTM), we examine the perceptual, cognitive, and social factors that contribute to children’s rapid mastery of human language. Our approach is inherently interdisciplinary, bringing together insights and methodologies from developmental psychology, various branches of linguistics, and the speech sciences. Importantly, much of our research is inspired by the linguistic diversity in the community surrounding UTM.
