Differences in development appear very early -- in this instance, differences in vocabulary growth between children in low socio-economic households and high socio-economic households begin to appear as early as 18 months. And as the children grow toward school age, and enter school, the differences only get larger in the absence of intervention.
And it’s not just cognitive development that is affected by early experiences--it’s also social-emotional behaviors and physical health. This study investigated adults with a history of Adverse Childhood Experiences in early childhood to determine whether these experiences increase the odds that they would experience alcoholism, drug abuse, and a range of unhealthy behaviors later in life. Perhaps not unexpectedly, all of these behaviors increased dramatically in adults who had higher numbers and prevalence of Adverse Childhood Experiences in their early years. But this graph shows that these experiences also lead to dramatically increased odds of having a range of physical health problems as adults -- in this case, cardiovascular disease. And these trends also appeared for diabetes, hypertension, stroke, obesity, and cancer.

“ Although education and the acquisition of skills is a lifelong process, starting early in life is crucial. Recent research – some sponsored by the Federal Reserve Bank of Minneapolis in collaboration with the University of Minnesota – has documented the high returns that early childhood programs can pay in terms of subsequent educational attainment and in lower rates of social problems, such as teenage pregnancy and welfare dependency.”
Remarks by Federal Reserve Board Chairman Ben S. Bernanke
