Section 1: Physical Development

Adolescence is a fairly new concept 3 Categories: 1.Early Middle Late 18-21

Growth Spurt Abrupt growth – no longer continuous Except for infancy – most changes in life Girls by 10 or 11 Boys by 12 or 13 15% have difficulty adjusting to growth spurt

Sexual Development Adolescence begins with onset of puberty Puberty – specific developmental changes that lead to ability to reproduce Primary sex characteristics – directly involved in reproduction Secondary sex characteristics – not directly involved in reproduction

Hormones Changes come because of increased hormonal levels Boys – testosterone Girls – estrogen & androgens – Menarche & ovulation

Maturation Rates Boys that mature early have advantages – More popular, leaders, competitive edge in sports – More self-assured and relaxed, boosts self-esteem Girls that mature early = awkward – May be tempted to associate with older teens, could be teased or pressured – Usually not long-lasting effects

Cognitive Development Egocentrism – Imaginary audience – Personal fable -

Section 2: Social Development

Relationships with Parents Redefined Constant rebellion & quest for independence – especially early on Greater emotional attachment to friends – Boys: replace family time with alone time – Girls: replace family time with friends & alone time Usually share similar social, political, religious, economic views Interact more with mothers

Attachment to Parents Kids that feel close to parents: – Self-reliant – Independent – Better grades – Fewer adjustment problems

Relationship with Peers Why have friends? – Accept us for who we are – Loyal – Supportive and understanding – Contribute to self-esteem Who are they? – Similar in age, background, educational goals, etc. – Closest friends: usually same sex – Girls usually closer with friends

Peers (continued) Cliques– peer groups 5-10 people (both sexes) – Crowd – larger group that still shares attitudes – Imitate peer speech, dress, may be intolerant of outsiders Peer Influences – more likely to positively influence – Follow music tastes, hair styles, etc. Still more likely to follow parents on moral values, educational and career goals

Dating & Romantic Relationships Occurs in Stages 1.After-school events 2.Group dating 3.Traditional dating Why date? – Spending time with person – Learn how to relate to other people – Prepares for serious dating Young adolescents – dating is casual / short-lived

Section 3: Identity Formation

Task of Adolescence According to Erik Erikson: search for identity – A sense of who we are and what we stand for

Identity Development Find identity by choosing and committing to a particular role or occupation May try out different “selves” Identity crisis: turning point when we make life decisions Easier to do once we reach formal-operational stage

Identity Status James Marcia studied the ways we handle and cope with identity crisis Four categories of identity status 1.Identity Moratorium 2.Identity Foreclosure 3.Identity Diffusion 4.Identity Achievement

Identity Moratorium Search for identity Explore various alternatives Delay making commitments “I don’t know what I want to do when I graduate, so I’m going to apply to a few colleges. Then I’ll decide what’s best for me.”

Identity Foreclosure Conform Accept identity and values from childhood Choose to identify with others rather than self Make commitments and adopt plans without self- examination Become inflexible “Everyone in my family has gone into the military after high school, so that’s what I’m planning to do.”

Identity Diffusion Make no commitment No soul-searching Wander without goals Become angry and rebellious “I have no idea what I’m going to do after graduation. I’ll just have to see what happens.”

Identity Achievement Explore options Commit self to direction in life and occupation Find identity “I’m going to start college in the fall. My parents wanted me to go into the family business, but I decided I want to go to school to become a teacher.”

Gender & Ethnicity in Identity Formation GENDER Females equally concerned with occupation But more concerned with balancing day-to-day demands and occupation ETHNICITY Identity formation more complicated 2 sets of cultural values can cause conflict

Homework Many TV shows, novels, and movies are based on the experiences of young people trying to figure out how they fit into the world. You are going to pick three characters of your choice and describe which of Marcia’s states these characters appear to be in. Give reasons for your opinions. If a character appears to move from one state to another during the story, describe this process. Did something happen that seemed to cause the change?
