What is adolescence?
Adolescence, defined by World Health
Organization (WHO) as the period
between 10 and 19 years, is an
important, formative time which shapes
the future of girls' and boys' lives.

Period of Adolescence
Rapid growth (Mabilis ang paglaki)
Interaction of physical, psychological, and
environmental factors ( Katawan, Pag-iisip at
Kapaligiran)
Off timing of systems (Dahl, 2004)
 Puberty
 Physical growth
 Emotion and behavior regulation
Importance of understanding interaction of all the
systems; (Mahalaga na maintindihan ang
interaksyon nito)
Transitions all occur sequentially but not necessarily
at the same time
What’s the Big Deal?
Adolescent morbidity (aksidente o
sakuna)
Health Paradox (Dahl, 2004):
 Developmental period of strength and
resilience both physically and cognitively
 Yet, morbidity & mortality rates increase 200%
 DIFFICULTIES IN CONTROLLING BEHAVIOR
AND EMOTION
 Accidents, suicide, homicide, depression,
violence, reckless behavior, risky sex.
Overview
I. Physical Development
II. Cognitive Development
III. Psycho-Social Development
I. Physical Development
Height & Weight Changes
Secondary Sex Characteristics
Continued Brain Development
Rapid Gains in Height & Weight
4.1 to 3.5 inches per year
Girls mature about 2 years earlier than boys
Weight gain = muscles for boys; fat for girls
Secondary Sex Characteristics:
Pubic hair
Menarche or penis growth
Voice changes for boys
Underarm hair
Facial hair growth for boys
Increased production of oil, sweat glands, acne
Continued Brain Development
Not completely developed until late
adolescence
Emotional, physical and mental abilities
incomplete
May explain why some seem inconsistent
in controlling emotions, impulses, and
judgements
Understanding the Adolescent Brain
Advances in brain imaging allow
for better understanding of what
occurs
Evidence for frontal lobe delays
Inability to delay gratification;
impulse control
Suggestion that puberty
represents a period of synaptic
reorganization and as a
consequence the brain might be
more sensitive to experiential
input at this period of time in the
realm of executive function and
social cognition
Prefrontal cortex of interest (Blakemore & Choudhury, 2006)
Brain: Developmental
Changes
Synaptogenesis: proliferation of synapses
Myelinazation: insulation around synapses
Synaptic pruning: frequently used connections are
strengthened, infrequently used connections are
eliminated (Blakemore & Choudhury, 2006)
Bottom Line?
How do these change affect teens?
Usually studied as decision making
(Steinberg, 2004)
 In lab: similarities in adolescent & adult decision
making processes
Adolescents are uniquely vulnerable to risk
taking
 Novelty & sensation seeking increase dramatically
at puberty
 Development of self-regulation lags behind
Risk taking as group behavior (Steinberg,
2004)
How Do These Changes
Affect Teens?
Frequently sleep longer - 9 1/2 hours
May be more clumsy because of growth
spurts-body parts grow at different rates
Girls may become sensitive about weight -
60% trying to lose weight
1-3% have eating disorder
How Do These Changes
Affect Teens?
Concern if not physically developing at same
rate as peers - need to “fit” in (early vs. late
maturation)
Feel awkward about showing affection to
opposite sex parent
Ask more direct questions about sex - trying
to figure out values around sex
What Can Adults Do?
Expect inconsistency in responsibility
taking and in decision making
Provide opportunities for “safe” risk
taking
Avoid criticizing/comparing to others
Encourage enough sleep
Encourage/model healthy eating
Encourage/model activity
Provide honest answers about sex
II. Cognitive Development
Advanced Reasoning Skills
Abstract Thinking Skills
Meta-Cognition
Beginning to Gain Advanced
Reasoning Skills
Options
Possibilities
Logical
Hypothetically
What if?
Think Abstractly
Can take others’ perspective
Can think about non-concrete things like
faith, trust, beliefs, and spirituality
Ability to Think About Thinking
Meta-cognition
Think about how they feel and what they are
thinking
Think about how they think they are perceived by
others
Can develop strategies for improving their
learning
How Do These Changes
Affect Teens?
Heightened self-consciousness
Believes no one else has experienced
feelings/emotions
Tend to become cause-oriented
Tend to exhibit a “justice orientation”
“It can’t happen to me” syndrome
What Can Adults Do?
Don’t take it personally when teens
discount experience
Discuss their behavior rules/consequences
Provide opportunities for community service
Ask teens their view and share own
III. Psycho-Social Development
Establishing identity
Establishing autonomy
Establishing intimacy
Become comfortable with one’s sexuality
Achievement
Establishing Identity
Erikson (1959): identity vs. identity diffusion
Integrates opinions of other into own
likes/dislikes—needs interactions with diverse
others for this to occur
Outcome is clear sense of values, beliefs,
occupational goals, and relationship expectations
Secure identities-knows where they fit
Identity Exploration Process:
Identity
Achievement
Identity
Foreclosure
Moratorium
Identity
Diffusion
Exploration
present
absent
present absent
Commitment
Marcia (1966)
Establishing Autonomy

• Learned within context of same-sex friendships;
then in romantic relationships
• Develops close, open, honest, caring, and trusting
relationships

relationships; practice social skills, and become
intimate from friends
Becoming Comfortable
with One’s Sexuality
• How educated/exposed to sexuality largely
determines if healthy sexual identity develops
• More than half high school students are sexually
active
• Mixed messages contribute to teen pregnancy
and sexually transmitted diseases
Predictors of Sexual Activity
• Having a steady boy/girlfriend
• Using alcohol regularly
• Having parents with permissive values about
sex
• Being worried about one’s future occupational
success
• Implication: focus on more than one risk
factor
Achievement
• Society fosters and values attitudes of
competition and success

Adolescent Growth and Development and Related Problem

  • 1. Adolescent Growth and Development and Related Problems Agnes Montalbo MA Industrial Psychology Instructor Department of Arts and Sciences Rizal Technological University agnesmontalbo@gmail.com 534-8267 May 29, 2012
  • 2. What is adolescence? Adolescence, defined by World Health Organization (WHO) as the period between 10 and 19 years, is an important, formative time which shapes the future of girls' and boys' lives.
  • 3. Source: Cooperative Extension System Extension "CARES" for America's Children and Youth Initiative March, 2001
  • 4. Short Activity In a piece of paper, write your most common problems with your adolescents and how do you handle problem behaviors Indicate the age and gender
  • 6. Period of Adolescence Rapid growth (Mabilis ang paglaki) Interaction of physical, psychological, and environmental factors ( Katawan, Pag-iisip at Kapaligiran) Off timing of systems (Dahl, 2004)  Puberty  Physical growth  Emotion and behavior regulation Importance of understanding interaction of all the systems; (Mahalaga na maintindihan ang interaksyon nito) Transitions all occur sequentially but not necessarily at the same time
  • 7. What’s the Big Deal? Adolescent morbidity (aksidente o sakuna) Health Paradox (Dahl, 2004):  Developmental period of strength and resilience both physically and cognitively  Yet, morbidity & mortality rates increase 200%  DIFFICULTIES IN CONTROLLING BEHAVIOR AND EMOTION  Accidents, suicide, homicide, depression, violence, reckless behavior, risky sex.
  • 8. Overview I. Physical Development II. Cognitive Development III. Psycho-Social Development
  • 9. I. Physical Development Height & Weight Changes Secondary Sex Characteristics Continued Brain Development
  • 10. Rapid Gains in Height & Weight 4.1 to 3.5 inches per year Girls mature about 2 years earlier than boys Weight gain = muscles for boys; fat for girls
  • 11. Secondary Sex Characteristics: Pubic hair Menarche or penis growth Voice changes for boys Underarm hair Facial hair growth for boys Increased production of oil, sweat glands, acne
  • 12. Continued Brain Development Not completely developed until late adolescence Emotional, physical and mental abilities incomplete May explain why some seem inconsistent in controlling emotions, impulses, and judgements
  • 13. Understanding the Adolescent Brain Advances in brain imaging allow for better understanding of what occurs Evidence for frontal lobe delays Inability to delay gratification; impulse control Suggestion that puberty represents a period of synaptic reorganization and as a consequence the brain might be more sensitive to experiential input at this period of time in the realm of executive function and social cognition Prefrontal cortex of interest (Blakemore & Choudhury, 2006)
  • 14. Brain: Developmental Changes Synaptogenesis: proliferation of synapses Myelinazation: insulation around synapses Synaptic pruning: frequently used connections are strengthened, infrequently used connections are eliminated (Blakemore & Choudhury, 2006)
  • 16. How do these change affect teens? Usually studied as decision making (Steinberg, 2004)  In lab: similarities in adolescent & adult decision making processes Adolescents are uniquely vulnerable to risk taking  Novelty & sensation seeking increase dramatically at puberty  Development of self-regulation lags behind Risk taking as group behavior (Steinberg, 2004)
  • 17. How Do These Changes Affect Teens? Frequently sleep longer - 9 1/2 hours May be more clumsy because of growth spurts-body parts grow at different rates Girls may become sensitive about weight - 60% trying to lose weight 1-3% have eating disorder
  • 18. How Do These Changes Affect Teens? Concern if not physically developing at same rate as peers - need to “fit” in (early vs. late maturation) Feel awkward about showing affection to opposite sex parent Ask more direct questions about sex - trying to figure out values around sex
  • 19. What Can Adults Do? Expect inconsistency in responsibility taking and in decision making Provide opportunities for “safe” risk taking Avoid criticizing/comparing to others Encourage enough sleep Encourage/model healthy eating Encourage/model activity Provide honest answers about sex
  • 20. II. Cognitive Development Advanced Reasoning Skills Abstract Thinking Skills Meta-Cognition
  • 21. Beginning to Gain Advanced Reasoning Skills Options Possibilities Logical Hypothetically What if?
  • 22. Think Abstractly Can take others’ perspective Can think about non-concrete things like faith, trust, beliefs, and spirituality
  • 23. Ability to Think About Thinking Meta-cognition Think about how they feel and what they are thinking Think about how they think they are perceived by others Can develop strategies for improving their learning
  • 24. How Do These Changes Affect Teens? Heightened self-consciousness Believes no one else has experienced feelings/emotions Tend to become cause-oriented Tend to exhibit a “justice orientation” “It can’t happen to me” syndrome
  • 25. What Can Adults Do? Don’t take it personally when teens discount experience Discuss their behavior rules/consequences Provide opportunities for community service Ask teens their view and share own
  • 26. III. Psycho-Social Development Establishing identity Establishing autonomy Establishing intimacy Become comfortable with one’s sexuality Achievement
  • 27. Establishing Identity Erikson (1959): identity vs. identity diffusion Integrates opinions of other into own likes/dislikes—needs interactions with diverse others for this to occur Outcome is clear sense of values, beliefs, occupational goals, and relationship expectations Secure identities-knows where they fit
  • 29. Establishing Autonomy Becoming independent and self-governing within relationships Make and follow through with decisions • Live with own set of principles of right/wrong • Less emotionally dependent on parents
  • 30. Establishing Intimacy • Learns intimacy and sex not same thing • Learned within context of same-sex friendships; then in romantic relationships • Develops close, open, honest, caring, and trusting relationships • Learn to begin, maintain, and terminate relationships; practice social skills, and become intimate from friends
  • 31. Becoming Comfortable with One’s Sexuality • How educated/exposed to sexuality largely determines if healthy sexual identity develops • More than half high school students are sexually active • Mixed messages contribute to teen pregnancy and sexually transmitted diseases
  • 32. Predictors of Sexual Activity • Having a steady boy/girlfriend • Using alcohol regularly • Having parents with permissive values about sex • Being worried about one’s future occupational success • Implication: focus on more than one risk factor
  • 33. Achievement • Society fosters and values attitudes of competition and success • Can see relationship between abilities, plans, aspirations • Need to determine achievement preferences, what good at, and areas willing to strive for success
  • 34. How Do These Changes Affect Teens? • More time with friends • May keep a journal • More questions about sexuality • Begin to lock bedroom door • Involved in multiple hobbies/clubs • More argumentative • Interact with parents as people
  • 35. What Can Adults Do? • Encourage involvement in groups • Praise for efforts and abilities • Help explore career goals and options • Help set guidelines/consequences • Establish rituals for significant passages • Know friends and what they are doing • Provide structured environment/clear expectations

Editor's Notes

  1. 2 developmental processes Puberty and cognitive development; progress at different rates “starting the engine with an unskilled driver” “igniting passions” Have ‘turbo charged feelings” with learners permit driving skills
  2. Compared to young children, adolescents are stronger, bigger, and faster and are achieving maturational improvements in reaction time, reasoning skills, immune function and the capacity to withstand cold, heat, injury, and physical stress Also illustrate better reasoning and decision making skills than young children **What accounts for morbidity? Major sources are related to difficulties in the control of behavior and emotion It’s high rates of accidents, suicide, homicide, depression, ATOD, violence, reckless behavior, risky sex… DIFFICULTIES IN CONTROLLING BEHAVIOR AND EMOTION—MOST RECKLESS DECISIONS ARE EMOTIONALLY BASED
  3. Executive function=capacity that allows coordination of thoughts and behaviors—selective attention, decision making, voluntary response inhibition and working memory e.g. allows you to filter out unimportant information, holding in mind a plan to carry out in the future and inhibiting impulses PREFRONTAL CORTEX Involved in multiple aspects of cognitive processing It’s a proposed mediator of behavioral planning and reasoning, attentional processes, impulsivity and response inhibition Given this the contention is that some adol who experiment with ATOD may not be able to moderate their impulsivity—and consider alternative behavioral choices and consequences—or to inhibit a response
  4. Normative synaptogensis and pruning—0-3 literature—sensitive periods—e.g. language development—unused areas are eliminated Most of this is linear with the exception of the prefrontal cortex Suggested that prefrontal cortex pruning is ignited during puberty but continues up until age 30!
  5. We have historically tried to understand adol risk taking by focusing on their decision making process Results show that risk perception and appraisal change very little between adolescence and adulthood In laboratory settings, adolescents appear quite similar to adults in their decision making process Flaws in methods- Give hypothetical scenarios which negates emotional element Study adol individually, but risk behavior tends to occur in groups Steinberg (2004) suggests that “the greater propensity for adolescents to take risks is not due to age differences in risk perception or appraisal, but to age differences in psychosocial factors that influence self-regulation” Adolescents is a heightened vulnerability to risk taking because of a disjunction between novelty and sensation seeking (both of which increase dramatically at puberty) and the development of self-regulatory competence (which does not fully mature until early adulthood) which is biologically driven and normative. Interventions should aim to reduce the harm associated with risk taking
