Learning Outcomes
• Participants will understand the developing
brain and its functions.
• Participants will be become more aware of
brain research
• Participants will be able to create strategies
that translate current brain research into
developmentally appropriate activities.

Prenatal Development
• The nervous system begins
to develop just before the
third week of gestation.
• Cell creation and movement
to the right spots occur
during the first five prenatal
months.

Take Home Messages
 The traditional nature versus nurture debate is
simplistic and scientifically obsolete
 Early experiences clearly influence brain
development, but the focus on birth to three
begins too late and ends too soon
 Early intervention programs can improve the odds
for vulnerable young children, but those that work are
rarely simple, inexpensive, or easy to implement

Take Home Messages
 How young children feel is as important as how they
think, particularly with regard to school readiness
 Healthy early development depends on nurturing
and dependable relationships
 Culture influences all aspects of early development
through child-rearing beliefs and practices

Take Home Messages
 Substantial evidence indicates that poor nutrition,
specific infections, environmental neurotoxins, drug
exposures, and chronic stress can harm the
developing brain
 Significant parent mental health problems,
substance abuse, and family violence impose
heavy developmental burdens on young children
 There is little scientific evidence that special
“stimulation” activities beyond normal, growthpromoting experiences lead to “advanced” brain
development in infancy
