Sleep/Wake States of Preterm Infants: Stability, Developmental Change, Diurnal Variation, and Relation with Caregiving Activity.
Peer reviewed Peer reviewed
Ingersoll, Evan W.; Thoman, Evelyn B. – Child Development, 1999
Used time-lapse video to record sleep/wake states of preterm infants for three 24-hour periods at 33 and 35 weeks conceptional age. Found that very-low-birthweight preterm infants showed marked stability and developmental change in the organization of sleep/wake states from a very early age, and their states were related to demographic variables…

Variability in Early Communicative Development.
Peer reviewed Peer reviewed
Fenson, Larry; And Others – Monographs of the Society for Research in Child Development, 1994
Data from parent reports on 1,803 children, derived from the MacArthur Communicative Development Inventories, are used to describe the course of communicative development between 8 and 30 months of age. Found wide variability in children's rate of lexical, gestural, and grammatical development; correlations between several components of language…
