What is an emerging adult: between adolescence and adulthood, theory presented in the journal american psychologist in 2000. A period of ti(cid:373)e to e(cid:454)plore possi(cid:271)ilities a(cid:374)d defi(cid:374)e o(cid:374)e(cid:859)s self, (cid:449)hile feeling caught between adolescence and adulthood: markers of transition: Why is this a new life stage: most people leave school and home at older ages, age of marriage is gradually increasing. 31 for men, 29 for women: age at parenthood is also increasing.

Processes tasks like: calibration of risk and reward, problem solving, prioritizing, long term planning, self-evaluation. More extensive myelination of nerves in this area of the brain: synaptic pruning. Nerve connections are prunes back = more efficient signal transmission among the nerves.
