What is the "set point"?
the level of hormones that the body tries to maintain
if below: endocrine system increases the secretion
if above: stops the secretion
What is the feedback loop?
- HPG axis
two or more body functions respond and regulate one another
The pituitary gland, hypothalamus, gonads
the pituitary gland regulates levels of hormones in the body
the hypothalamus controls the pituitary gland
the gonads secrete the sex hormones (testes and ovaries)

- BUT!! sexual activity is going down
- adolescent's these days are more INFORMED!!!
- therefore, people should not assume they are troubled or bad
- not needing as much supervision because they are showing the ability to make thier own proper decisions
the biosocial perspective
stresses the hormonal and physical changes of puberty as driving forces
all about the individual
- G.Stanley Hall
- each person travelled through stages that are determined by INSTINCT
changes are unavoidable
the organismic perspective
still stress the individual's changes BUT also looks at how the environment and contextual forces interact with the individual
Freud, Erikson, Piaget
a psychological revolution!
the learning perspective
stress the working of the environment on the individual
- Skinner-punishment and reinforcement
the sociological perspective
focus on the things that are common among a group of individuals, such as age, gender, ethnicity
depending on different social circumstances, everyone develops differently
the historical perspective
adolescence is a social invention
all issues depend on social, economic and political forces present
difference between cultural and biological reproduction
- biological puberty are the changes that occur to the individual
- the cultural puberty focuses on the cultural and social aspect of adolescence
- gender role
- overcoming challenges
- sexual change
- primary and secondary sex characteristics
- body hair
- to be a successful adolescence, these two must coincide
- different for every individual
- the endocrine system increases hormone production!
- Physical changes:
- in body composition
- in circulation and respiration
- of primary and secondary sex characteristics
- everyone goes through the same changes, although the time frame can be quite different (early VS late maturers)
- increased vulnerability for some
the endocrine system
hypothalamus stops inhibiting the pituitary gland
HPG axis-feedback loop that watches the levels of sex hormones
estradiol and testosterone
both are present in males and females, although more is found in one depending on their sex
related to secondary sex changes like boobs, hair...etc...
- changes in the skeletal system
- girls 2yrs ealier than boys
- happens earlier than period
- fixed sequenced...everyone goes through it
- 3:1 muscle in males
- 5:4 fat in women
- epiphysis: closing of the ends of the bones
- asymmetry of growth:hands and feet grow the quickest
could effect socialization and self esteem...
Circulatory and respitory changes
- size of lungs and heart increases
- capacity of heart and lungs increase
- exercise tolerance increases (higher in men)
Sexual matruation in boys
- typically occurs 1 year after accelerated penis growth
- and Reiser 1994 – retrospective reports from 36 boys, mean age = 18.6 yrs
- spermarche occurred at 12-13 years, typically 1 year after puberty begins, it
- is socially
**preparation increases positive reactions
- invisible, and the usual reactions are:
- confusion, surprise, pleasure
boys are able to father a child before they look like adults
Sexual maturation in girls
- less regular than in boys
- typically occurs after other secondary sex characteristics; regular ovulation
- follows 2 years later à
- girls appear physically mature before they are actually capable of reproduction
- of menarche correlates with: heredity,
- father absence, stress, family stress, living arrangements ~ 12 years
- •Secular trend - downward shift in the onset of
- menarche, stable in industrialized nations for 30 yrs
variation in timing and tempo of puberty
- no specific age-variable
- there are early and late maturers
- everyone reaches the final stage of puberty
- late maturers slightly taller
- late maturing girls are heavier
How does the biological effects of puberty affect adolescents behaviour?
- the individuals view of themselves (self esteem)
- other's view of the individual
Psychosocial effects of puberty on boys
Pros of early maturation
- •Perception of being an early or late maturer is more important in affecting one’s feelings
- than the reality
•Popularity, better self-esteem
•More responsible, cooperative, sociable later in adulthood
Cons of early maturation
- •More drug and alcohol use, precocious sexual activity, greater impact of
•Less creative, more humorless in later adulthood
Psychosocial effect of puberty on girls
•Compared to early maturing boys, early maturing girls have more difficulties
•Maturational deviance hypothesis
•Developmental readiness hypothesis
•Cultural and contextual factors (valuing thinner body types)
Pros of early maturation
•Popularity with boys
Cons of early maturation
•Heavier and shorter stature later in life
- •Precocious sexual activity, lowered self-image, higher rates of depression, eating
- disorders, anxiety
- most common in girls due to dissatisfaction of the body....increase in body fat
- most common disorder is OBESITY
- disordered eating means having unhealthy eating habits
What are the main conclusions that can be made about puberty?
- it is better to be ON TIME then OFF TIME
- PREPARATION is key!
- we make adjustments as a reaction to the context
delayed phase preference:
wanting to go to bed later and later in adolescence
investigates the pubertal stage and later bed times to physical maturation, birth order, school type, family and peer groups
- FOUND: physical maturation is more important than psychosocial factors
- BUT you can't say the environment has no effect....
Larson and Richards:
compared emotional ups and downs with random mood sampling and self report of pubertal status
FOUND: adolescence overall has biggest mood changes BUT it was related to environmental factors... NOT PUBERTAL STAGE
1. Thinking about possibilities
- thinking about what could be
- no longer fixed by the observable
- career choices are increased
- "what would happen if..." (Idealism)
- more than one thing can be thought about at once
- if...then....(hypothetical reasoning)
Chapell and Overton study on deductive reasoning
- findings, formal reasoning improved with age
- adolescence improve with deductive logic
- think better about things that a RELEVANT to them
What is the competence/performance distinction?
- the adolescent can think deductively but doesn't mean they will act that way
- knowing VS doing
- motivated by society and motivation
2. Thinking abstractly
- mental symbols begin to appear ( democracy, justice, truth)
- thinking without the senses
- Propositional logic: if A is true, and B is true, then C is also true
assimilation VS accomodation!!! experiencing new things and then changing them to accomodate new info...
- thinking about thinking
- "thinking take wings"-Piaget
- 20 questions EXAMPLE: adolescence thinks about the questions in order to get the appropriate answers
- introspection increases!
What is adolescent egocentrism?
- everything is about YOU
- bring on the verge of discovery
- Imaginary audience: everyone is looking at you
- Personal fable:linked to risky behaviours, trying to make yourself different than other.. being unique
4. Thinking in multiple dimensions
thinking about more than one aspect of a situation, word or topic
- EXAMPLE: applying for a job! many thoughts are in your head
- who am I?
- what do I want to be?
- sarcasm becomes increasingly possible
- more into adult thinking rather than egocentrism
5. Adolescent relavitism
- black and white disappear!!
- beginning to question things
- agruments-choosing your battles
- different rights and wrongs are thought about
- PROCESS THEORY
- really emphasized the difference between how a child thinks from how an adolescent thinks to how an adult thinks....thought they were verrrrryyyy different
- all about maturation
- sensorimotor-preoperational-concrete operations-formal operations
- everyone goes through these stages in this order
- sensory-->internalized thought
- the progressive movement into internalized thought
- BUT WHAT ABOUT CULTURE?!!!
- explaining a more gradual change between child and adolescent thinkingfocuses on specific parts of thinking and the development of them
- with enough info, you can advance the child!
- all about quantity
- molding the brain by new information
- the more the info, the more the child's brain has the capacity to think
chronological definition of adolescence
- focus on age
- when does it begin and end?
- puberty starts before adolescence
- defining adolescence on the time frame that is begins and ends
sociological definition of adolescence
- when is adult status conferred?
- lots of variation
- different opportunities given at different ages
- driving, drinking, voting, dating
psychological definition of adolescence
the engagement and completion of the developmental tasks that mark adulthood
Havinghurst's 9 tasks
accepting their physique
- forming relationships
- emotional independence
- intellectual skills
- marriage and kids prep
- establishing values
if struggling with any of those listed above, the individual is not able to focus their attention on things that are more important and adult like.
therefore, they need to develop and mature psychosocially
What is biological determinism?
- strictly looking at the changes occuring during adolescence as biological processes
- the pubertal and hormonal changes effect the psychosocial development of the adolescent
Is adolescence filled with turmoil?
- Hall: YES! storm and stress
- Arnett: No!! it is moderate
- the storm and stress model states that the hormones are out of control and therefore, so are the teens....they are irresponsible...
- but this goes against research (generation tame)
is adolescence a cultural invention?
examined historical portrayals of adolescence
economic depression: the were seen as dependant, immature, psychologically unstable and requiring education (treated more like children)
in war time: seen as mature, psychologically competent, and not needing education (treated more like adults)
IN CONCLUSION:social construction: adolescence are constructed depending on the needs and values of the economic and cultural tastes of the society
