2. "Adolescence is the period of life from about
13 to early 20s, during which a person is no
longer physically a child but not yet an
independent, self-supporting adult"
Definition
3. • Early Adolescence: puberty begins, desire for independence,
abstract thinking, greatly influenced by their peers (11-13)
• Middle Adolescence: end of puberty, greater self-involvement,
goal-setting, new friends (14-18)
• Late Adolescence: end of physical development, thinking about
the future, stronger sense of identity, serious relationships (19-21)
Stages Overview
4. Examining Different Types of Development
• Physical: Puberty begins and end,
allowing the body to grow and
reach sexual maturity
5. Examining Different Types of Development
• Cognitive: Initially focused on the present and not consequences, but
over time begin to plan for the future and set achievable goals
+ Attempt to gain independence by distancing selves from parents
+ Struggle with identity but find stability with age
6. Examining Different Types of Development
• Psychosocial: Strongly influenced by peer group early on but
begin to branch out to new groups as identity consolidates
+ Romantic relationships in early years are short-lived but in
later years longer-term relationships develop
7. Adolescent Development & Piaget's Formal
Operational Stage
• Begins at 11 or 12 but continues into adulthood
• Abstract concepts, deductive reasoning, problem-solving
• Instead of relying on previous experiences, individuals
consider potential outcomes within hypothetical
scenarios
8. Early Adolescence (11-13)
Physical: Onset of puberty--body
hair, weight gain, height increase, and
sexual interest
+ Girls: breasts and menstruation
+ Boys: genitals, voice deepens
+ Overall, girls' development is faster
than boys’
9. Early Adolescence (11-13)
Cognitive: Abstract thought, interest in careers, but more
focused on the present and near future
Psychosocial: Awkward about developing bodies, influenced by
peer group, struggle with identity
+ Rule and limit testing and a strong desire for
independence (may argue more with parents and spend
more time with friends)
10. Middle Adolescence (14-18)
• Physical: Puberty ends
and physical growth
continues at a slower rate
for girls but is still steady
for boys
• Cognitive: Goal-setting,
moral reasoning,
existentialism
11. Middle Adolescence (14-18)
Psychosocial: Self-involvement that oscillates between
unrealistic high expectations and anxiety about failure
+ Lowered opinions of parents
+ Selection of role models
+ New friends and focus on popularity
+ Love and passion, with frequently changing relationships
and concerns about sexual attractiveness
12. Late Adolescence (19-21)
• Physical: Most girls are fully
developed but boys often continue to
grow
• Cognitive: future-oriented thinking,
sense of identity, emotional stability,
self-reliance, delay of gratification,
moral reasoning
• Psychosocial: clearer sexual identity,
serious relationships, cultural traditions
might gain importance
Editor's Notes
+ Inability to evaluate long-term consequences explains the rashness of adolescent behavior
+ Many researchers believe that certain aspects of "rebellion" may be necessary for breaking away from childhood dependence on parents and becoming a self-sufficient adult
