Document Summary

Childhood experiences set the stage for lifetime experiences. 3 years old: 70% of brain is adult size. Low birth weight babies had 18 years significantly lower intelligence. Regions of the brain mature at different ages. Reversal is impossible if iron deficiency occurs in infancy because the iron assists in permanent structural changes in the brain. Brains frontal lobe continues to develop through adolescents (thought and consciousness) Absence from school and poor environment lead to iq declines. Time and effort spent on active learning are important determinants of cognitive performance. Alcohol exposure messes with attention and information processing speed. Maternal nutrition in the first trimester is critical to avoid miscarriage. Foetal origins of disease- vulnerable to diabetes, high blood pressure and coronary heart disease (low weights at birth and infancy) Most dramatic results are seen from those suffering extreme deprivation and abuse. Sibling correlations with siblings sharing the same genes rather then adopted.
