Week 7 - Adolescence Flashcards
adolescence
period of the life span between the time puberty begins and the time adult status is approached, when young people are preparing to take on the roles and responsibilities of adulthood in their culture
puberty
changes in physiology, anatomy and physical functioning that develop a person into a mature adult biologically and prepare the body for sexual reproduction
What triggers the puberty
proportion of fat in the body increases to reach a threshold level, a series of chem events are then triggered in hypothalamus.
oestrogens
sex hormones that have especially high levels in females from puberty onwards; they are mostly responsible for female primary and secondary sex characteristics
androgens
sex hormones that have especially high levels in males from puberty onwards; they are mostly responsible for male primary and secondary sex characteristics
oestradiol
the oestrogen most important in pubertal development among girls
testosterone
the androgen most important in pubertal development among boys
_______ sex characteristics are directly related to reproduction: specifically, the production of ova (eggs) in females and sperm in males.
Primary
________sex characteristics are the other bodily changes resulting from the rise in sex hormones during puberty, not including the changes related directly to reproduction.
Secondary
menarche
first menstrual period
spermarche
first ejaculation
Now scientists have learned that a sharp increase in synaptic connections occurs around the time puberty begins (10–12 years), a process called ______ or ______
overproduction or exuberance.
Overproduction peaks at about age _______, followed by _______
11 or 12
A massive amount of synaptic pruning
between the ages of 12 and 20, the average brain loses ___-___% of its volume through synaptic pruning
7–10%
________ is the last structure of the brain to stop growing, not completing its phase of overproduction and pruning until the mid-20s
Cerebellum
secular trend
change in the characteristics of a population over time
Research consistently shows that the effects of early maturation are usually _________for girls.
negative
he Growing Up in Australia study found that girls who matured early scored lower on measures of socioemotional functioning (like dealing with their emotions, getting along with peers and coping with school) at ages 8–9 and 10–11, but by ages 12–13, ___________________________________________
there were no differences based on stage of pubertal development
Dieting is very common, with one study finding that 90% of Australian teen aged girls and 68% of teenaged boys had been on a diet of some kind, and 1 in 5 girls had fasted, in the previous month
Anorexia is characterised by four primary symptoms:

According to Piaget (1972), the stage of formal operations begins at about age ___ and reaches completion somewhere between ages ___ and ___
11
15 and 20
formal operations
in Piaget’s theory, cognitive stage beginning at age 11 in which people learn to think systematically about possibilities and hypotheses
hypothetical-deductive reasoning
Piaget’s term for the process of applying scientific thinking to cognitive tasks
The limitations of Piaget’s theory of formal operations fall into two related categories:
individual differences in the attainment of formal operations and
the cultural basis of adolescent cognitive development.
On any given Piagetian task of formal operations, the success rate among late adolescents and adults is only ___-___% depending on the task and on individual factors such as educational background
40–60%
Adolescents become more proficient at both _______and _______ attention, and they become better at using _________strategies.
