Document Summary

Psyc 2450- ch 6: physical development of the brain, body, motor skills. Changes in body proportions: a newborn"s head is 70% of it"s eventual adult size & makes up of their total body weight. Cephalocaudal development- a sequence of physical maturation and growth that proceeds from the head (cephalic region) to the tail (caudal region). Skeletal age- a measure of physical maturation based on the child"s level of skeletal development: skeletal development is done by 18, but the thickness increases slightly throughout life. Variations in physical development: physical growth is uneven (asynchronous, brain, reproductive system & lymph tissues mature at diff rates, sizeable individual & cultural differences in development. Increases from 25% of eventual weight to 75% of eventual weight by 2. Brain growth spurt- the period between the 7th prenatal month and 2 years of age where more than half of the child"s eventual brain weight is added. Synapses- the connective space between one nerve cell (neuron) and another.
