A developmental psychologist who studied children’s acquisition of number-word meanings. A seven-month longitudinal study compared what two- and three-year-olds could count with what quantities they understood particular words to denote. This distinction underlies number-word knower level: reciting a counting sequence need not mean understanding the quantities its words represent.[ref]
