Developmental Change in Infant Cortisol and Behavioral Response to Inoculation.
Peer reviewed Peer reviewed
Ramsay, Douglas S.; Lewis, Michael – Child Development, 1994
Infant cortisol and behavioral responses to receiving one versus two inoculations on one pediatric office visit were observed at two and six months of age. The findings indicate a developmental trend for a decline over age in adrenocortical reactivity to inoculation for infants showing a cortisol release following perturbation. Results were…

The Relationship between Physical Growth and Infant Behavioral Development in Rural Guatemala.
Peer reviewed Peer reviewed
Lasky, Robert E.; And Others – Child Development, 1981
Investigated the relationship between anthropometric indices and behavioral development during the first two years of life in rural Guatemala. Body length and weight most strongly correlated with behavioral development. When length and weight were controlled statistically, variance in behavioral development was accounted for. (Author/DB)

Newborns' Orientation toward Sound: Possible Implications for Cortical Development.
Peer reviewed Peer reviewed
Clifton, Rachel K.; And Others – Child Development, 1981
Newborns were presented with a tape-recorded rattle sound through a single loudspeaker, through two loudspeakers with one onset leading the other by seven msecs., and through two loudspeakers simultaneously. Newborns turned toward the single source sound, but not toward either of the dual source sounds. (Author/RH)

Visiting in the Intensive Care Nursery.
Peer reviewed Peer reviewed
Rosenfield, Abby G. – Child Development, 1980
Analyses were made of the pattern and frequency of mothers' visits to the intensive care nursery for premature infants. Visiting was found to be uncorrelated with medical, socioeconomic, or demographic variables, but was apparently related to significantly higher state levels achieved by infants who received a program of early stimulation.…

Spontaneous Leg Movements of Infants with Down Syndrome and Nondisabled Infants.
Peer reviewed Peer reviewed
Ulrich, Beverly D.; Ulrich, Dale A. – Child Development, 1995
Compared the spontaneous leg movements of 10 infants with Down Syndrome to those of nondisabled infants matched for chronological age and motor age. Contrary to expectations, no significant difference was found in the frequency of leg movements between the two groups. However, Down Syndrome subjects demonstrated significantly fewer of the most…

EEG Patterns of Preterm Infants, Home Environment, and Later IQ.
Peer reviewed Peer reviewed
Beckwith, Leila; Parmelee, Arthur H. Jr. – Child Development, 1986
Studied the sleep state organization and EEG patterns at term date in 53 preterm infants as an index of the maturity and integrity of neurophysiological organization that may have implications for their later development. (HOD)

Analysis of Cry Features in Newborns with Differential Fetal Growth.
Peer reviewed Peer reviewed
Zeskind, Philip Sanford; Ramey, Craig T. – Child Development, 1981
Describes the relationship between neonatal crying and anthropometric indices of fetal growth. No differences were found between cry features of underweight and overweight infants; both groups required more stimulation than average weight infants to elicit crying. It is suggested that certain cry features may reflect the risk status of neonates…
