chapter 5; Physical and Cognitive Development in Early Childhood Flashcards
why is it good that the growth rate slows in early childhood
if continue to grow we would be giants

brain growth slows down
how much of adult volume does the brain reach by 6 years old

leaner

no, they vary from one individual to another
what is involved with the variation of growth patterns
heredity
environmental experiences
what are the two most important contributors to height differences
- ethnic origin
- nutrition
the continuing development of the […] and others parts of the […] system are the most important physical developments during early childhood
brain
nervous
the increasing maturation of the brain, combined with opportunities to experience a widening world, contribute to the children’s emerging […] abilities
Cognitive
what do changes in the brain during early childhood enable children to do ?
plan their actions, attend to stimuli more effectively, and make considerable strides in language development
does the brain grow as rapidly during early childhood as in infancy
no, the brain does not grow as rapidly during early childhood as in infancy, it undergoes remarkable changes
what types of growth do the children’s brains experince
rapid, distinct spurts of growth
what patterns change dramatically in the brain from ages 3 to 5
local patterns within the brain
what happens to brain material from ages 3 to 5
- amount of brain material in some areas can nearly double in as little as a year
- followed by a dramatic loss of tissue as unneeded cells are pruned and the brain continues to recognize itself
from ages 3 to 6 years where is the most rapid growth in the brain
frontal lobes aka the prefrontal cortex
