FRHD*1010 Week 7: Adolescent Physical, Cognitive, and Socioemotional Development

Comprehensive practice flashcards covering physical, cognitive, and socioemotional development in adolescence from Chapter 7 and Chapter 8 of FRHD*1010.

What is puberty, and what are its primary biological characteristics?

Puberty is a brain-neuroendocrine process of rapid physical changes occurring primarily in early adolescence in which individuals reach sexual maturity and achieve the capacity for sexual reproduction.

Based on this graph of pubertal growth spurts, at what approximate ages do females and males reach their peak height gain?

Females reach their peak height gain at approximately $11\frac{1}{2}$ years of age, whereas males reach their peak height gain approximately $2$ years later, at around $13\frac{1}{2}$ years of age.

What are the three components of the HPG axis, and what role does each play in pubertal development?

The HPG axis consists of the Hypothalamus (which monitors eating and sex), the Pituitary gland (which controls growth and regulates other endocrine glands), and the Gonads (testes in males and ovaries in females, which give rise to pubertal bodily changes).

Which specific hormones dominate female and male pubertal development?

Estradiol dominates female pubertal development, whereas testosterone dominates male pubertal development.

How do the psychosocial impacts of early maturation differ between adolescent girls and boys?

Early maturation places girls at higher vulnerability for problems including smoking, drinking, depression, eating disorders, and earlier sexual experiences; early maturation in boys is typically experienced positively during adolescence, though late-maturing boys report more positive identity experiences by their $30\text{s}$.

What is menarche, and what environmental and health conditions are associated with later menarche?

Menarche is the female body's first menstruation, occurring relatively late in the pubertal cycle; higher socioeconomic status (SES), better overall health, and lower exposure to stress and threats are associated with later menarche.

According to Hock et al. (2025), what percentage of adolescents reported a discrepancy between their real body and their ideal body image?

$55\%$ of adolescents reported a discrepancy between their real and ideal body image, with $20\%$ reporting being smaller than ideal and $35\%$ reporting being larger than ideal, particularly among high users of social media.

What adverse infant outcomes are specifically associated with adolescent pregnancy?

Adolescent pregnancy creates significant health risks for the infant, including preterm birth, low birth weight, low Apgar scores, and increased mortality.

What percentage of adolescents experiment with substances, and what specific proportions use alcohol versus opiates?

Approximately $44\%$ of adolescents experiment with substances, with $25\%$ reporting alcohol use and $20\%$ reporting opiate use.

How much sleep do adolescents typically need, and how does their biological clock shift during puberty?

Most adolescents require approximately $9$ hours of sleep per night, but their internal circadian rhythm undergoes a biological shift that delays sleepiness, causing them to go to bed and wake up later.

How do anorexia nervosa and bulimia nervosa differ in their clinical presentations and typical body weight status?

Anorexia nervosa involves a relentless pursuit of thinness through starvation, affecting $1\%$ of females (occurring $10$ times more often than in males); bulimia nervosa involves a consistent binge-and-purge cycle, affecting $1\%$ of the population ($90\%$ women in late adolescence), with individuals typically remaining within a typical weight range.

What cognitive capabilities define Jean Piaget's formal operational stage?

The formal operational stage is characterized by abstract, idealistic, and logical thought, including the capacity for hypothetical-deductive reasoning (generating hypotheses and systematically deducing testable implications) and thinking about thought itself.

According to David Elkind, what are the two core manifestations of adolescent egocentrism?

1. Imaginary audience: the heightened self-conscious belief that others are as intensely interested in them as they are in themselves.
2. Personal fable: a profound sense of personal uniqueness and invincibility or invulnerability.

In this figure showing stimuli used to measure cognitive control, how does adolescent performance differ between the Cool Stroop task and the Hot Stroop task?

Performance increases linearly with age in the cool Stroop task (top row), but dips during adolescence in the hot Stroop task (bottom row) due to reduced inhibitory control in emotionally arousing contexts.

What neurodevelopmental imbalance explains heightened risk-taking behaviors during adolescence?

The limbic system (the lower subcortical seat of emotions and reward processing, including the amygdala) matures earlier than the prefrontal cortex (responsible for judgment and inhibitory cognitive control), resulting in elevated dopamine-driven sensation seeking before self-regulation fully develops.

What is the 'top-dog phenomenon' in the context of school transitions?

The circumstance of moving from the most powerful, oldest, and largest student position in an elementary school to the least powerful, youngest, and smallest student position in middle school or high school.

What were the high school completion rates for Métis, First Nations, and Inuit populations aged 25 to 64 in Canada in 2021?

In $2021$, high school completion was $82.0\%$ for Métis (a $4.6$ percentage point increase from $2016$), $69.9\%$ for First Nations (a $5.5$ percentage point increase), and $50.1\%$ for Inuit (a $4.7$ percentage point increase).

What is service learning, and under what conditions is it most effective?

Service learning is a form of education promoting social responsibility and community service; it is most successful when students have the autonomy to choose their service activities and are provided formal opportunities to reflect on their participation.

According to Erik Erikson, what is the core crisis of adolescence, and what does psychosocial moratorium mean?

The stage is Identity versus Identity Confusion; psychosocial moratorium is the developmental gap between childhood security and adult autonomy during which youth experiment with various identities without full adult commitments.

What are James Marcia's four identity statuses based on crisis (exploration) and commitment?

1. Identity Diffusion: no crisis experienced and no commitment made.
2. Identity Foreclosure: commitment made without having experienced a crisis.
3. Identity Moratorium: in the midst of a crisis, but commitments are absent or vague.
4. Identity Achievement: has undergone a crisis and successfully made a commitment.

What are 'MAMA cycles' in identity development?

Repeated developmental cycles shifting between Moratorium and Achievement (moratorium-achievement-moratorium-achievement), reflecting an ongoing, fluid process of identity restructuring.

What four basic questions define effective parental monitoring strategies?

Parents must consistently know: (1) Where the youth is (2) Who they are with (3) What they are doing (4) When they left and will be home

How does parent-adolescent conflict typically progress across adolescence according to modern developmental models?

Conflict escalates in early adolescence, remains relatively stable, and lessens around $16$ to $20$ years of age; modern models recognize that moderate, everyday conflicts are normal and healthy for scaffolding autonomy rather than severing emotional attachment.

Based on this graph, how do self-disclosing conversations with friends versus parents change from grade 2 through the college/university years?

Self-disclosure to friends increases sharply from grade $2$ to grade $10$, surpassing parents around grade $5$; self-disclosure to parents drops steeply through grade $10$, but begins to recover during college and university.

What distinguishes cliques from crowds in adolescent peer group structures?

Cliques are small, personal groups of $2$ to $12$ individuals (averaging $5$ to $6$) of similar age and gender who share mutual activities; crowds are larger, less personal group reputations based on shared images or activities whose members may not spend much time together.

What are Connolly and McIsaac's (2009) three developmental stages of adolescent romantic relationships?

1. Ages $11$ to $13$: Romantic attractions and affiliations triggered by puberty.
2. Ages $14$ to $16$: Exploring romantic relationships through casual dating and group dating.
3. Ages $17$ to $19$: Dyadic romantic bonds featuring serious, enduring emotional attachments typically lasting $1$ year or more.

What are the four conflict interaction profiles identified among adolescent romantic partner dyads?

1. Dyads with rigid interactions (value freedom, enforce strict rules, high conflict)
2. Dyads with entangled interactions (highly emotional and co-dependent)
3. Dyads with hampered interactions (highly emotional but with low communication)
4. Dyads with balanced interactions (equitable balance of independence and dependence)

What is a rite of passage, and does Canadian society feature universal formal rites of passage?

A rite of passage is a ceremony or ritual that marks an individual's transition from one developmental or social status to another; Canada does not have universal formal ceremonies marking the passage from adolescence to adulthood.

What is sensation seeking, and how does its developmental timing relate to impulse control?

Sensation seeking is the drive to experience novelty, reward, and arousal (often involving risk); it peaks during middle adolescence and is stronger than impulse control and self-regulation at this stage.

How is bullying defined, and which types of children are most frequently victimized?

Bullying is defined as aggressive, intentional acts carried out repeatedly against a victim who cannot easily defend themselves; anxious and socially withdrawn children are commonly victimized because they are unlikely to retaliate, while aggressive children are often targeted by other bullies.

What are the epidemiological patterns of adolescent depression and suicide in Canada?

Depression is more common in adolescent females than males (globally except in China); suicide is the second-leading cause of death among Canadian $10$- to $19$-year-olds, with rates peaking among females during adolescence and shifting to highest among males in emerging adulthood.
