PSY310H5 Chapter Notes - Chapter 5: Cognitive Training, Iatrogenesis, Relational Aggression
Document Summary
High school students in the us and europe spend twice as much time each week with peers than with parents or adults, even outside class. This is correlated with more positive mood for the adolescents. American society is very age graded, from as early as daycare. This plays an important role in forming friendships (peer groups - groups of people of same age). Not all societies have peer groups that are as narrowly defined and age segregated as those in contemporary industrialized societies. Age grading started in the middle of the 19th century, but most adolescents weren"t affected by the educational grading until the second quarter of the 20th century (especially high school). There was a rapid growth of the teenage population between 1955 and 1975 (baby boomers after wwii). This trend decreased from 1975-1995, but increased again in. 1990s once the baby boomers" kids grew to become adolescents.
