For example, only about half of the 4- and 5-year-olds tested by Liberman et al.

The original scale was based on the normative data that was collected from a carefully conducted longitudinal study of early human development. The study focused on the various stages of developing and how they unfolded over time. [1] Throughout the years, it has been subjected to ...
