describe physical, cognitive, and motor changes over the lifespan. what is happening at each stage and when does peak/plateaued growth occur

physical

height and weight, sexual maturation, senescence, primary aging, secondary aging

sexual maturation begins

females 11, males 12

height and weight plateau

females 12, males 15

sexual maturation pleateau

females 14, males 18

sexual maturation peak

females 14, males, 16

height and weight peak

females between 11-13, males 14-16

piaget's theory of development

four stage, no peak or plateau, growth can continue or decline at any time

cognitive

piaget's theory of development

motor

milestones

senescence

natural physical decline brought about by increase aging

motor peak and plateau

no real peak or plateau, maybe after 2 years it plateaus slightly

milestones

3.2 months rolling over, 11.5 months standing alone well, 23.8 months jumping in place

primary aging

aging that involves universal and irreversible changes that, due to genetic programming can occur as people get older

secondary aging

changes in physical and cognitive functioning that are due to illness, health habits, and other individual differences but are not due to increase age and are not inevitable
