Low birthweight children are at risk for motor, language and cognitive delay in early childhood. The aim of the present study is the examination of cognitive skill development among 4-year-old preterm and low birthweight children in relation to demographical and perinatal variables. We utilized the Wechsler Preschool Primary Scales of…

It is well established that children's early life environments can have significant consequences on their long-term outcomes. Yet, there is still limited empirical evidence on the effects that being exposed during the prenatal and early postnatal periods to positive shocks, such as conditional cash transfers, has on long-term cognitive function.…

Executive control (EC) develops rapidly during the preschool years and is central to academic achievement and functional outcome. Although children with perinatal adversity are at known risk for EC impairments, little is known about the underlying nature of these impairments or the mechanisms that contribute to their development over time. Drawing…

Neuroscientists have long believed that there are sensitive periods in development during which the effects of experience play a critical role. And developmental psychologists have argued for the importance of early experience in the first years of life as being critical for brain and behavioral development. Most of the neuroscience research…

Background: Maternal depression is known to be associated with impairments in child cognitive development, although the effect of timing of exposure to maternal depression is unclear. Methods: Data collected for the Avon Longitudinal Study of Parents and Children, a longitudinal study beginning in pregnancy, included self-report measures of…

Objective: No previous longitudinal study has examined the impact of comorbid maternal personality disorder (PD) and depression on child development. We set out to examine whether maternal PD and depression assessed at 2 months post partum would be independently associated with adverse developmental outcomes at 18 months of age. Method: Women were…

Fetal magnetoencephalography (fMEG) is the only non-invasive method for investigating evoked brain responses and spontaneous brain activity generated by the fetus "in utero". Fetal auditory as well as visual-evoked fields have been successfully recorded in basic stimulus-response studies. Moreover, paradigms investigating precursors for cognitive…

To study the effects of perinatal HIV-1 infection and early institutional rearing on the physical and cognitive development of children, 64 Ukrainian uninfected and HIV-infected institutionalized and family-reared children were examined (mean age = 50.9 months). Both HIV infection and institutional care were related to delays in physical and…

The developing brain has the capacity for a great deal of plasticity. A number of investigators have demonstrated that intellectual and language skills may be in the normal range in children following unilateral perinatal stroke. Questions have been raised, however, about whether these skills can be maintained at the same level as the brain…

Perinatal asphyxia occurs in approximately 1-6 per 1000 live full-term births. Different patterns of brain damage can result, though the relation of these patterns to long-term cognitive-behavioural outcome remains under investigation. The hippocampus is one brain region that can be damaged (typically not in isolation), and this site of damage has…

The aims of this study were to determine the motor outcome of extremely-low-birthweight (ELBW; less than 1000g) or very preterm (less than 28wks) children compared with normal birthweight (NBW) children, to establish the perinatal associations of developmental coordination disorder (DCD) and its cognitive and behavioural consequences. Participants…

A total of 35 variables descriptive of birth and obstetric complications, prematurity, maternal discomfort, and demographic status were studied for a sample of 322 infants. Factor analyses of these variables resulted in seven major factors that were used to predict developmental status at 1 year of age for 233 of the subjects. (Author/SB)

Results of twin studies clearly demonstrate that genetic factors play an important role in the rate of language acquisition and linguistic proficiency attained by normal and impaired children and adults [see Stromswold, K. (2001). The heritability of language: A review and meta-analysis of twin, adoption and linkage studies. "Language," 77,…

Reviewed are the causes of oxygenation deprivation during the birth process, effects on the brain, clinical manifestations, developmental consequences in terms of cognitive and motor deficits, and implications for educators. (JDD)

This study examining children's understanding of biological inheritance addressed four central questions: (1) are young children able to distinguish between the relative influences of nature and nurture in their understanding of how physical characteristics versus behaviors and preferences develop in animals? (2) does children's understanding of…
