The on-going research in the lab falls into three areas related to cognitive development. In one line of research, we investigate issues related to children’s developing understanding of representations such as mental states (e.g., beliefs, intentions, opaque contexts) and symbols (e.g., numbers, written words, drawings, and maps). In the second, we investigate issues relating to young children’s developing Executive Function skills (e.g., inhibitory control and cognitive flexibility). In the third, (in collaboration with Dr. Jo-Anne LeFevre), we investigate children’s developing understanding of numeracy skills such as counting principles and place value.
