Summary of development across the lifespan

Summary of development across the lifespan Over a lifespan, development occurs with a certain predictability. However, variables such as socioeconomic levels, nutrition and level of education influence development. PRENATAL Increase in number and size of nerve cells to attain 25% adult brain weight and size at birth. Brain is particularly susceptible to teratogens in weeks 3 to 5 in the embryonic period. INFANCY Extensive and rapid growth. CHILDHOOD Slows down. 75% of adult sized brain at age 3 and brain reaches maximum size by age 10. ADOLESCENCE Nerve connections and associations continue to build up. Myelination continues. ADULTHOOD No likely change to capacity. LATE ADULTHOOD 65-70 year olds in an industrialised country have lost 20% of nerve cells that were present at birth. This leads to less acuity but not capacity. Development across the lifespan

this topic is well understood.

Most of the development happens during the childhood period.

The summary of development across the lifespan is based upon Social, Language, Emotional, muscle, & physical. growth happens in steps as such, prenatal infancy, childhood, adolescence, adulthood and late adulthood. The rate of development depends mostly upon the health of that person.

This topic is well understood. The summary of development across the lifespan, I understand that at childhood stage of development slows down. 75% of adult sized brain at age 3 and brain reaches maximum size by age 10.

Development is a complex, multidimensional and gradual process

with this module , I think I understood my previous question but if anyone can throw more light, I don't mind.
