ABSTRACT
Adevelopmental student is interested in change and, apart fromprenatal development, infancy is the period of
most rapid and comprehensive change. Psychologists have developed an increasing sophistication about the
rapidly developing competencies of newborns and infants.Much of the research depends on good design, sys-
tematic observation, and detailed recording procedures. Prolonged familiarity with developing babies and
sharpened observational skills are the initial tools of the infancy researcher.
