Document Summary

Adolescence development: different layers of change, different rates of change. Developing body hair, sexual organs (tanner scale), faster bone growth, increase of appetite and sleep. Biological age does not equal to pubertal age (hormonal age) Increase of body fat cause early onset of puberty (one directional) Adolescents are: more likely to make risky decisions (response inhibition and calibration of risk and rewards); more capable of making abstract, multidimentional, planned, hypothetical thinking in late adolescence to adulthood (faster deductive reasoning, information processing) Social environment plays an important role in calibration of risk and reward and response inhibition. 13-16yrs are more likely to make risky decisions in front of peers than older people. Age is not correlated with sensation seeking but pubertal stage is. Adolescent alcohol use increases bold responses in parts of the frontal cortex, decreases wm volume, psychological functioning and pfc volume.
