Exploring effective interventions to compensate for developmental delay in premature neonates and reduce their mothers' anxiety is of great significance. This research aimed at examining the effects of body massage on Iranian premature neonates' physical and motor development, and on their mother's anxiety and attachment. Forty premature neonates…

The behavior of newborns is ambiguous. Cultural models--representations shared by members of a community--provide new parents and others with a cognitive and motivational structure to understand them. This study asks members of several cultural groups (total n = 100) to judge the "similarity" of behavioral items in the Neonatal…

Preterm birth is associated with an increased risk of developmental difficulties. Magnetic resonance imaging (MRI) is increasingly being used to identify damage to the brain following preterm birth. It is hoped this information will aid prognostication and identify neonates who would benefit from early therapeutic intervention. Cystic…

Identifies a coordinative structure of action that integrates hand and mouth activities within hours after birth. Found that presenting neonates with a sucrose solution focused gross motor patterns of hand movement on the oral and perioral regions. (SKC)

Studied hand-mouth coordination in 40 infants of 1-3 days. Sucrose solution was delivered intraorally every 2 minutes. Results provide evidence for sucrose as a calming agent and for a coordinative behavorial system that integrates hand-mouth activity in supine human infants. (RJC)

Cyclical fluctuation in spontaneous motor activity (CM) emerges in fetus and persists in newborn. This "resetting" experiment perturbed CM by noise stimulus during infants' active sleep. Pre- and postperturbation CM were measured and compared. Subjects were 33 infants between 1 and 3 days of age. The stimulus induced a relative slowing of CM…

When tendon jerk reflexes were tested in seven newborns from one- to three-days old, stretch reflex responses in all major muscle groups of the lower limb were elicited. This "irradiation of reflexes" is a normal phenomenon in newborns, with the pathway becoming suppressed during normal maturation. In individuals with cerebral palsy,…

The organization and structuring of spontaneous arm movements of eight neonates were studied quantitatively, with each movement divided into an acceleration phase and a deceleration phase. Found that the movements of the two arms were coupled in all three dimensions of space and had a tendency to follow the body's longitudinal axis. (MDM)

Examined asymmetries in movement behaviors of 36 full-term, newborn infants. The majority of infants had right-biased movement behaviors. Multiple subsystems, rather than a single asymmetric system, appeared to control asymmetric action of different body regions. There were sex differences in asymmetry of distal lower body movement behaviors that…

Studied head position preference in 20 newborns differing by Cesarean or vaginal delivery and sex. Found that neither factor accounted for differences. The head turned right more often and was maintained longer in this position during quiet wakefulness, regardless of scoring method. When using global scoring, duration of midline position was…

This study examined responsiveness of the suck central pattern generator to external stimulation, based on premise that early control of sucking and smiling sets stage for more differentiated use of orofacial muscle system for speech. A device for the stimulation of intraoral tissues in neonates, called the actifier, features a wide frequency…

Reports comparisons of behaviors of nine chimpanzee and nine human newborns on a standardized human neonatal assessment scale at the ages of three days and one month. Human infants scored higher than chimpanzee infants on the orientation cluster at both ages, but were lower than chimpanzee infants in motoric maturity. (RJC)

Examined the effects of hunger on the hand-mouth (HM) behavior of a group of newborn infants. Found that significantly more mouth opening before contacts to the mouth than those to the face occurred before but not after feeding, suggesting some link between HM behavior and hunger state. (MDM)
