In most of our social life we communicate and relate to others. Successful interpersonal relating is crucial to physical and mental well-being and growth. This study, using the still-face paradigm, demonstrates that even human neonates (n = 90, 3-96 hr after birth) adjust their behavior according to the social responsiveness of their interaction…

Brain damage due to an episode of hypoxia remains a major problem in infants causing deficit in motor and sensory function. Hypoxia leads to neuronal functional failure, cerebral palsy and neuro-developmental delay with characteristic biochemical and molecular alterations resulting in permanent or transitory neurological sequelae or even death.…

In the human brain, the morphology of cortical gyri and sulci is complex and variable among individuals, and it may reflect pathological functioning with specific abnormalities observed in certain developmental and neuropsychiatric disorders. Since cortical folding occurs early during brain development, these structural abnormalities might be…

Despite decades of studies of human infants, a still open question concerns the role of visual experience in the development of the ability to perceive complete shapes over partial occlusion. Previous studies show that newborns fail to manifest this ability, either because they lack the visual experience required for perceptual completion or…

Women with severe psychiatric illness face numerous risks and challenges during pregnancy and as parents. Mental health professionals can help these mothers and their infants by supporting the attachment relationship and by providing the external supports that are necessary for successful parenting. The authors describe a hospital-based…

Studied the effect of varying amount and concentration of a sucrose solution on swallowing and sucking activity of newborns. (Author/JMB)

The relation between cry acoustics and vagal tone in normal, healthy newborns undergoing an acutely stressful event was examined. Vagal tone was significantly reduced during the stressful event and was paralleled by significant increases in the pitch of the infants' cries. (PCB)

The device described is a system to indicate left-to-right head position. It is limited to indicating relative left-right movements without vertical or up-down discrimination. Although developed for newborns, the system can be applied to older subjects by using a holding device for the infant. (JH)

This most recent Iowa Kids Count data book, "Iowa Kids Count 2011: Trends in the Well-Being of Iowa Children," provides data on 20 different indicators of child and family well-being at the United States, Iowa, substate and county level. The annually produced data book presents health, education, welfare and economic data including…

When predicting child developmental outcomes, reliance on children's scores on measures of developmental functioning alone might mask more subtle behavioral difficulties, especially in children with developmental risk factors. The current study examined predictors and stability of examiner behavior ratings and their association with concurrent and…

Paradoxically, fear conditioning (odor-0.5 mA shock) yields a learned odor preference in the neonate, presumably due to a unique learning and memory circuit that does not include apparent amygdala participation. Post-training opioid antagonism with naltrexone (NTX) blocks consolidation of this odor preference and instead yields memory of a learned…

Displaying no evidence of recognizing the axillary odors of their fathers, breastfed infants discriminated between their mother's axillary odor and odors produced by nonparturient or unfamiliar lactating females. Bottle-fed infants appeared unable to recognize the odor of their mother when presented along with odors from a nonparturient female or…

Investigated the influence of arousal level on visual preferences by observing the looking preferences of 12 full-term neonates twice; once before feeding while unswaddled and once after feeding while swaddled. (Author/RH)

The temporal organization of spontaneous movement in healthy, awake neonates was studied on the second or third day after birth. Movement was recorded using time lapse photography and quantified as a function of time. Evidence of intrinsic temporal organization among subjects was found. (MP)

To study sensitivity to radial location of an odor source, 20 human newborns, ranging from 16 to 130 hours of age, were presented with a small amount of ammonium hydorxide. (Author/JMB)
