• Environment-
  nurture- refers to the
  sum of all external
  conditions that affect a
  child
• Can seriously affect
  development
• This is an “enriched”
  environment------>
• Deprivation refers to a
  lack of normal
  stimulation, nutrition,
  comfort and love
• Cambodian homeless
  children
• --------- deprived
  environment
• When an environment    • Poverty can lead to

  more complex,            unhappiness and
  intellectually           aggression
  stimulating, and       • Neglecting a child
  emotionally              may cause damage

• Proven to enhance        intellectual stimulation
  development
• Encourage exploration by stimulating play
  and paying attention to what holds a baby’s
  interest
• Let the child investigate and discover
• Surround babies with colors, music, people,
  or rearrange their rooms once in awhile.
  SENSORY enrichment is VERY important
• The first 3 months of
  pregnancy is a time
  when a fetus is more
  susceptible to
  environmental
  influences and can
  alter development
• Another example is
  forming a bond with a
  caregiver early in life
• Nurture starts before
  birth
• A baby’s heart rate
  and movements will
  increase with loud
  sounds
• If a mother’s health or
  nutrition were poor the
  fetus may be harmed
• This is from Agent
  Orange- a chemical
  used to wipe out
  Charlie in Vietnam
• Pesticides- I assume
  the mother was
  drinking water or
  eating food
  contaminated with
  them
• This is caused by a
  mother giving birth
  while infected with
  syphilis- rashes occur
  as well
• Addiction causes babies to be born addicted
• General anesthetics, cortisone, excessive
  amounts of vitamins A, D, K, tranquilizers,
  steroids, aspirin- lowers infant IQs
• Excessive drinking
  can cause retardation,
  low birth weight,
  small head, bodily
  defects and facial
  malformations
• Many suffer
  emotional, behavioral
  and mental handicaps
• Smoking during
  pregnancy reduces
  oxygen supply to the
  fetus
• Heavy smokers risk
  miscarriage or having
  premature,
  underweight babies
  who can die soon after
  birth
• Anything capable of causing birth defects is
  called a teratogen
• Sometimes exposure is accidental-
  radiations, pesticides, lead
• Some are preventable- don’t smoke, drink
  or do drugs while pregnant
• Babies learn countless bits of information
  like how to eat with a fork, proper manners.
  How to read etc.
• There is nothing genetic about these
  activities
• Heredity gives us a variety of potentials and
  limitations
• This is affected by environmental influences
• This is your current
  state of physical,
  emotional and
  intellectual
  development
• These factors-
  heredity, environment,
  and your own
  behavior- determine it.
