HDFS: Adolescence: Unit 1 Exam
Elongation of Adolescence
-Adolescence lasts longer today than ever before -Start puberty earlier and enter into adult roles of work and family later -Elongation of adolescence has had important implications for how young people see themselves, relate to others, and develop psychologically
Thinking about possibilities
-Example: Ways in which their lives might be affected by different career choices -Moves easily between the specific and the abstract to generate alternative possibilities -Development of deductive reasoning "If-then" thinking Major intellectual accomplishment
Environmental factors of puberty
-Nutrition -Environmental molecules (e.g. plastics and pesticides) -Stress -Social interaction (siblings, prescence of father)
Physical Manifestations of puberty
-Rapid growth -Development of primary and secondary sex characteristics -Changes in body composition

-oral -anal -PHILLIC (adolescents r in) -latency -genital
Erickson's Psychosocial Stages
1)Trust v mistrust 2)autonomy v shame 3)initiative v guilt 4)industry v inferiority 5)IDENTITY V ROLE CONFUSION (adoles) 6)intimacy v isolation 7)generativity v stagnation 8)integrity v despair
Process of decision making
1. identify alternative choices 2.indentify consequences 3. Evaluate the costs and benefits (desirability) of each possible outcome 4. assess liklihood of each possible consequnce 5. combine all info to make final decision adults and adolescents differ in 3... way costs and benefits differently adolescents less future oriented and more succeptible to influence
Piaget's stages of cognitive development
1. sensorimotor 2. preoperational 3. concrete operational (early adolescence) 4. FORMAL OPERATIONAL (adolescent) >metacognition, egocentrism >construct involvement in world through interaction

middle adolescence
14-17 (high school)
late adolescence
18-21; transitioning out of high school and into college and the real world
adolescent egocentrism
A characteristic of adolescent thinking that leads young people (ages 10 to 13) to focus on themselves to the exclusion of others. results in imaginary audience and personal fable
Organismic Theories
Assumes that genetically organized processes are the primary determinant of psychological development ; focuses on processes within the individual ; assumes that individuals are active rather than passive ; internally biologically structured and interfere with environment
maturational deviance hypothesis
Being "off" relative to peers promotes psychological distress and behavioral problems.

In adolescence, appearance of more systemic, abstract thinking Seen through adolescents facility and interest in thinking about abstract concepts: interpersonal relationships (friendship), politics (democracy), religion (faith), morality (fairness and honesty)
positive reinforcement
Increasing behaviors by presenting positive stimuli, such as food. A positive reinforcer is any stimulus that, when presented after a response, strengthens the response.
negative reinforcement
Increasing behaviors by stopping or reducing negative stimuli, such as shock. A negative reinforcer is any stimulus that, when removed after a response, strengthens the response. (Note: negative reinforcement is not punishment.)
Intimacy, dating, and marriage
Need for new decisions about sexual activity
hypothetical-deductive reasoning

Historical and Anthropological Theories
Recognition that adolescence as a developmental period varies from one point in history to another (ex. growing up during industrial revolution)
Vygotsky's Socio Cultural Theory
Social interaction is critical to the development of thinking and problem-solving; stages in the development of reasoning reflect internalized language learning occurs across two levels > interaction (interpsychological) and mental structure (intrapyschological)
estrodial
Steroid made from estrogen that gives women female characteristics. increases 8 times for girls and only doubles for boys
Recapitulationism
The idea that the stages of each person's intellectual, emotional, and psychological development pass through the same stages as our pre-human ancestors as they developed into the humans of today (savage nature of adolescence) (biosocial theory)

Albert Bandura
pioneer in observational learning (AKA social learning), stated that people profit from the mistakes/successes of others; Studies: Bobo Dolls-adults demonstrated 'appropriate' play with dolls, children mimicked play individuals need a sense of self efficiency to succeed accomplishments are socially judged > rely on others to find out how we're doing

More Knowledgeable Other
- According to Vygotsky, we turn to a More Knowledgeable Other (MKO) as we learn tasks and skills. The MKO may be a teacher, parent, or other adult. However, peers including other children may also serve the role of MKO
