boys vs girls height and weight
boys are slightly taller and bigger than girls
brain development
-2 years old brain is 75% of total wight
-5 years old brain is 90% of adult weight
what increases brain size
myelination of nerve fibres
linking the cerebellum to the cerebral cortex helps in what way
development with fine motor skills, balance and coordination
from age 4-7 the nerves have been more myelinated what does this mean for development?
brain can be involved in the ability to sustain attention and screen out distractions
what hemisphere dominant is right handed people
left hemisphere
right hemisphere functions
visual-spatial functions, aesthetic and emotional response
plasticity if the brain
brains ability to compensate for injuries to particular parts of the brain
left hemisphere function
more involved in intellect, logical analysis, problem-solving language and computation.

1-2 years of age it is lessened as adulthood comes
what contributes to the brains plasticity
sprouting: growth of new dendrites
Gross Motor Skills
involve large muscles used in locomotion, like balancing on one foot, walk up stairs
what is crucial to positive life-long cognitive development
motor development
preschoolers should spend how many hours a week in large- muscles activity
25hours+
when does motor activity level decline
2 to 3 years of age, they are less restless can sit longer
