“…It took another decade for researchers to observe the newborn further for patterns of movement. Seminal work by Gilmer, McGraw, Wolff, and others [Gilmer, 1933;Pratt, 1935;McGraw, 1939;Wolff, 1959;Brazelton, 1961;Cobb, Grimm, Dawson, 1967;Korner, 1969] revealed that neonates have a repertoire of behaviors that are spontaneous yet can be elicited or diminished resulting in the development of assessments designed to assess more complex forms of behavior [Rosenblith, 1961;Brazelton, 1973]. These assessments, such as the Neonatal Behavioral Assessment Scale (NBAS), [Als, et al, 1977] have been used extensively to explore individual differences in infant behavior and how they are related to genetics and specific experiences of the infant prior to and during birth.…”
