Chapter 9 & Chapter 10 Flashcards
The Nature of Adolescence
There is a long history of worrying about how adolescents will turn out….the majority of adolescents today have positive self-concepts and positive relationships with others…public attitudes about adolescence emerge from a combination of personal experiences and media portrayals, neither of which produces an objective picture of how normal adolescence develop…in matters of taste and manners, the young people of every generation have seemed radical, unnerving, and different from adults-different in how they look, in how they behave, in the music they enjoy, in their hairstyles, and in the clothing they choose…acting out and boundary testing are time-honored ways in which adolescents move toward accepting, rather than rejecting, parental values.
Although the majority of adolescents experience the transition from childhood to adulthood more positively than is portrayed by many adults and the media,
too many adolescents today are not provided with adequate opportunities and support to be competent adults.

Body image
Preoccupation with one’s body image is strong throughout adolescence, but it is especially acute during puberty….in general, throughout puberty, girls are less happy with their bodies and have more negative body images, compared with boys….as puberty changes proceeds, girls often become more dissatisfied with their bodies, probably because their body fat increases, whereas boys become more satisfied as they move through puberty because their muscle mass increases.
Early maturation of males
11 1/2 early maturing - perceive themselves more positively and more successful peer relations, in part due to athletic achievement, more attention from girls, disadvantages: being exposed to things not emotionally/socially mature enough to be exposed to. In their 30’s, not as strong of a sense of identity as late maturing males
late maturing males
perceive themselves as less, feel physically and social inferior, but they have a better sense of self later in life.
early maturing females
experience more problems in school but also enjoy more independence and popularity with boys. Early maturation increases girls vulnerability to a number of problems: smoking, drinking, depression, eating disorders, earlier dating and sexual experiences.
late maturing females
socially disadvantaged with boys. At an advantage in their own personal development.
The brain
the amygdala (region of the brain that handles the processing of information about emotion) matures earlier than the prefrontal cortex (region of the brain involved in higher order cognitive functioning)…adolescents respond more with “gut” level reactions to emotional stimuli because the region of the brain that plans, sets priorities, suppresses impulses and weighs consequences is still “under construction”.

managing sexual feelings, developing new forms of intimacy, and learning the skills to regulate sexual behavior to avoid undesirable sexual consequences.
