Adolescent Development and Transitions Flashcards

Comprehensive question-and-answer practice flashcards covering biological, cognitive, social, and theoretical transitions in adolescent development.

What are the three fundamental changes of adolescence?

Biological changes (puberty), cognitive changes (thinking ability and brain processes), and social changes (societal definition of the individual).

Which brain structures and glands make up the hormonal feedback loop during puberty?

The Hypothalamus, Pituitary Gland, and Gonads, which regulate sex hormones (androgens and estrogens).

What is adrenarche and what hormonal output does it increase?

Adrenarche is the process through which the adrenal glands mature, leading to high levels of cortisol (the stress hormone) and increased vulnerability to mental disorders.

What two distinct hormonal processes drive physical and behavioral changes at puberty?

Organizational processes (occurring before adolescence) and activational processes (occurring when puberty takes place).

What is the epiphysis and what does its closing mark?

The epiphysis is the closing of the long bones in the body, which serves as one biological marker of the end of puberty.

How does body composition change differently for adolescent boys and girls during puberty?

Muscle grows faster in boys, whereas the increase in body fat is greater among females.

What specific factors make adolescent girls most susceptible to body dissatisfaction?

Maturing early, dating early, being affluent, and spending a lot of time talking to and comparing themselves with friends.

How do Black adolescent girls differ from white adolescent girls regarding body image?

Black adolescent girls report being less dissatisfied with their bodies, are less likely to diet, and may have different ethnic ideals for body type.

What is the key difference sequence between boys and girls regarding physical maturity and reproductive capability?

Girls become physically mature before they can actually reproduce, whereas boys become capable of reproduction before they finish physically maturing.

What is delayed phase preference in adolescents?

A biological tendency emerging after puberty where adolescents naturally stay up later at night and sleep later in the morning.

What three factors explain why early maturation is often harder on girls than boys?

Maturational deviance (standing out from peers), developmental readiness (requiring psychological adaptation without preparation), and cultural desirability of body types.

What are the primary prevalence statistics for adolescent obesity and overweight rates in the US?

14% of adolescents are obese and 16% are overweight (rates have leveled off since 2000), with the highest increased rate seen in Black females.

What is the leading cause of mortality among adolescents in the United States?

Unintentional injuries, which account for 45% of adolescent deaths, primarily from car accidents.

What is metacognition?

Thinking about thinking, which involves monitoring cognitive activity during the thought process, explaining what one knows, introspection, and heightened self-consciousness.

What two concepts define adolescent egocentrism?

The imaginary audience (believing everyone else is focusing on one's appearance or behavior) and the personal fable (believing one's experiences and feelings are uniquely individual).

According to Piaget, what stage of cognitive development is reached during adolescence?

Formal Operational thought, which is characterized by abstract logical reasoning and hypothetical ('if-then') thinking.

What two major structural developments occur in the adolescent brain to increase connection efficiency?

Synaptic pruning (elimination of unused neural connections) and increased myelination (permitting more efficient connections within and between brain regions).

In Robert Sternberg's Triarchic Theory of Intelligence shown in the diagram, what three types of intelligence are identified?

Analytical intelligence (academic problem solving), Creative intelligence (imaginative problem solving), and Practical intelligence (street smarts and common sense).

In Howard Gardner's Theory of Multiple Intelligences shown in the chart, what intelligence domains are represented?

Spatial, naturalist, musical, logical-mathematical, existential, interpersonal, bodily-kinesthetic, linguistic, and intrapersonal intelligence.

What are Lev Vygotsky's two key concepts regarding cultural learning and instruction?

The Zone of Proximal Development (learning achieved through collaboration with more experienced individuals) and Scaffolding (structuring the learning environment within the reach of the student).

What is Theory of Mind in social cognition?

The ability to understand that other people hold beliefs, intentions, and knowledge that differ from one's own.

How does Behavioral Decision Theory explain adolescent risk-taking?

It views decision-making as a cost-benefit analysis where adolescents systematically place greater weight on potential rewards than on potential risks.

What is sensation seeking?

The pursuit of novel and intense experiences, which increases and reaches a peak during adolescence.

Which policy interventions are effective in reducing adolescent risk-taking?

Limiting opportunities (such as graduated drivers licenses with passenger restrictions), economic policies (increasing anti-tobacco costs), and legal restrictions on access to firearms, alcohol, and tobacco.

What is the core argument of the Inventionist perspective on adolescence?

That adolescence is primarily a social construct created during the 19th-century Industrial Revolution to keep young people out of the workforce through compulsory schooling.

What age range defines Emerging Adulthood, and what are its five main features?

Ages 18 to 25; characterized by identity exploration, instability in work/living situations, self-focus, feeling in-between adolescence and adulthood, and a subjective sense of broad possibilities.

What research findings exist regarding juvenile competency to stand trial?

Studies show that 1/3 of juveniles under age 13 and 1/5 of 14- and 15-year-olds are not competent to stand trial, performing similarly to mentally ill adults found incompetent.

What rationale was given in Roper v. Simmons (2005) regarding the death penalty for juveniles?

The Supreme Court ruled that adolescents should not receive the death penalty because they are too immature to be held fully responsible for criminal behavior.

How do continuous and discontinuous pathways into adulthood differ?

Continuous transitions involve a gradual assumption of adult roles bit-by-bit (e.g., working on a family farm), whereas discontinuous transitions involve abrupt entry into adult roles (e.g., moving directly from full-time schooling to full-time work).

According to 2016 census data, what percentage of young adults aged 18 to 34 were living with their parents?

32%.

What is G. Stanley Hall's Theory of Recapitulation?

A biosocial theory stating that individual psychological development parallels the evolutionary history of the human species, viewing adolescent 'storm and stress' as an inevitable biological process.

Along the theoretical continuum shown in the diagram, where do Biosocial, Organismic, Learning, Sociological, and Historical/Anthropological perspectives fall?

Biosocial is extremely biological, followed by Organismic, Learning, and Sociological, with Historical/Anthropological being extremely environmental.

According to anthropological theories, how do continuous and non-continuous societies differ in their transition through adolescence?

Continuous societies (typically nonindustrialized) transition youth to adulthood peacefully, whereas non-continuous societies (industrialized, with rapid social change) make the entrance into adulthood abrupt and difficult.

In Uri Bronfenbrenner's Ecological Systems Model shown in the diagram, what are the nested environmental levels?

Microsystem (immediate influences), Mesosystem (system interactions), Exosystem (indirect influences), Macrosystem (culture/laws), and Chronosystem (dimension of time).

According to the model of neighborhood influence shown in the diagram, through what three mediating mechanisms do neighborhood conditions impact adolescent development?

Community norms and collective efficacy, interpersonal relationships, and economic and institutional resources.
