Using neonatal novelty exposure, a neonatal
stimulation paradigm that dissociates maternal individual differences from a direct
stimulation effect on the offspring, we investigated the
effect of
early exposures to novelty on a diverse range of psychological functions using several assessment paradigms.
Early interventions in high - risk situations have the highest return, presumably through mitigating the
effects of toxic stress by providing nurturance,
stimulation, and nutrition.
Analyses of findings from an
earlier intensive child development program for low birth weight children and their parents (the Infant Health and Development Program) suggest that the cognitive
effects for the children were mediated through the
effects on parents, and the
effects on parents accounted for between 20 and 50 % of the child
effects.10 A recent analysis of the Chicago Child Parent Centers, an
early education program with a parent support component, examined the factors responsible for the program's significant long - term
effects on increasing rates of school completion and decreasing rates of juvenile arrest.11 The authors conducted analyses to test alternative hypotheses about the pathways from the short - term significant
effects on children's educational achievement at the end of preschool to these long - term
effects, including (a) that the cognitive and language
stimulation children experienced in the centres led to a sustained cognitive advantage that produced the long - term
effects on the students» behaviour; or (b) that the enhanced parenting practices, attitudes, expectations and involvement in children's education that occurred
early in the program led to sustained changes in the home environments that made them more supportive of school achievement and behavioural norms, which in turn produced the long - term
effects on the students» behaviour.
