Chapter 6 Adolescence Flashcards
(93 cards)
WHAT IS ADOLESCENCE?
Adolescence is the period of transition between childhood and adulthood. Therefore,
it can be regarded as a developmental bridge between being a child and becoming an
adult. However, demarcating adolescence by age has led to various stance.
Demarcating adolescence
Adolescence has not always been seen as a distinct life stage.
Before the 19th century, children lacked formal education, married young, and
quickly took on adult roles.
The rise of formal schooling and children’s rights led to adolescence being recognized
as a transitional period from childhood to adulthood.
Due to research and globalisation (the process of increased international interaction
and cultural exchange), most countries now acknowledge adolescence as an important
life stage.
The age range for adolescence varies: from 10 to 24 years, sometimes broken into
early, middle, and late adolescence.
o Early: 10-14
o Middle: 15-18
o Late: 19-24
More accurate than age are physical, psychological, and sociocultural indicators to
define adolescence.
It begins with puberty and ends with meeting societal norms like independence, self-
reliance, and starting a career.
In South Africa, adolescence legally ends at 18, though this is often not a reliable
indicator.
There are exceptions to legal definitions (e.g., a 12-year-old girl can get an abortion
without parental consent).
Contrary to popular belief, adolescents today mature more slowly, taking longer to
take on adult responsibilities like working or driving.
A possible cause is adolescents’ preference for spending more time online.
The book follows the view that adolescence spans from approximately 12 to 18 years.
A stormy phase
There is vagueness about where adolescence begins and ends, and differing views on
its psychological characteristics.
One common view is that adolescence is a time of conflict, moodiness, and high-risk
behaviours, often referred to as a “stormy period” with biological roots.
This negative perspective is ancient—Socrates described adolescents as rebellious,
disrespectful, lazy, and rude.
However, others believe adolescents today are unfairly judged, and that they are
actually more informed, idealistic, open-minded, and aware of human rights than
previous generations.
Most psychologists now adopt a balanced perspective:
o Adolescence is a normal part of development with significant biological and
psychosocial changes.
o Most adolescents are well-adjusted and have values similar to their parents.
o Some do struggle—especially those from dysfunctional families.
o Adolescence is the ‘weak link’ where difficulties (if any) are most likely to
occur.
o Conflicts with parents are often not as serious as they seem.
Adolescence is a universal phenomenon, but cultural experiences differ:
o In traditional cultures, there’s more conformity and support from family and
community, resulting in less storm and stress—but this may reduce
independence and creativity.
o In Western cultures, there’s more individuality and creativity, but also more
risk-taking behaviour.
PHYSICAL DEVELOPMENT
Various important physical changes take place during adolescence. These include changes in
height, body mass, muscles, brain development, and sexual maturation. These changes will
be discussed next.
Adolescent growth spurt
Early adolescence is marked by the growth spurt, a rapid and intense phase of
physical growth.
The growth spurt is triggered by the growth hormone somatotrophin, which stimulates
the growth of nearly all body tissues, including bones, and significantly affects height
and weight.
In girls, the growth spurt typically starts at 10–13 years and ends around 16 years or
later.
In boys, it begins later—at 12–15 years—and ends around 18 years or later.
Despite starting earlier in girls, boys grow faster and usually end up taller than girls
by the end of adolescence.
Asynchrony refers to the uneven growth of body parts: legs, arms, hands, and feet
grow first, followed by the torso. This can make adolescents appear awkward.
After the skeleton’s growth slows, muscle mass increases:
o Girls’ bodies become rounded due to widening hips.
o Boys develop a more angular look due to broadening shoulders.
There are individual differences in physical development—some adolescents may
look like adults at 12 or 13, while others still resemble 10-year-olds. This is due to
genetic and environmental factors.
PHYSICAL DEVELOPMENT Brain development
As we have mentioned in Chapter 3, scientific advances in especially neuroimaging over the
past few decades have contributed to a much greater understanding of the growth of the
human brain from before birth to adulthood. Until quite recently, there had been a general
assumption in developmental psychology and neuroscience that major changes in the
architecture and functioning of the brain were limited to the prenatal period and the first five
or six years of life. However, neuroimaging has revealed that brain structure develops until
early adulthood (about 25 to 30 years of age).
Structural and functional changes in the brain during adolescence
Structural and Functional Brain Changes
The adolescent brain is remodeled through:
o Synaptic pruning – removes unused connections.
o Myelination – strengthens important neural pathways, especially in the corpus
callosum, improving information processing.
Uneven Brain Maturation
Different brain regions mature at different rates:
o The limbic system (emotions, rewards) matures early.
o The prefrontal cortex (planning, impulse control, long-term decision-making)
matures late – into the mid-20s.
o This mismatch explains risky behaviour: strong emotions + weak impulse
control.
o Metaphor: “Starting the engines with an unskilled driver and no brakes.”
Neurochemical Influences
Dopamine and serotonin increase, making adolescents:
o More emotional
o More reward- and thrill-seeking
o More responsive to stress
o More vulnerable to mental health issues (e.g., depression, anxiety, eating
disorders)
The Social Brain
The social brain helps adolescents understand facial expressions, emotions, and
others’ intentions.
During adolescence, it becomes hypersensitive to social cues, making teens:
o Easily embarrassed
o Highly influenced by peers
o More socially self-conscious
Emerging Cognitive Skills
As the prefrontal cortex develops, adolescents gain:
o Better executive functioning (self-control, planning, reasoning)
o Improved emotional regulation
o Greater sensitivity to others’ emotions and mental states
o Enhanced cause-effect reasoning
Biology, experience and plasticity: Influences on brain development in adolescence
Nature vs Nurture: What Comes First?
It’s debated whether:
o Brain changes (e.g. prefrontal cortex thickening) cause behavioural growth
(e.g. resisting peer pressure),
o Or if experiences (like resisting peer pressure) stimulate those changes.
The conclusion? It’s complex — both biology (nature) and experience (nurture)
interact continuously.
PHYSICAL DEVELOPMENT: Plasticity: The Brain’s Ability to Change
Two key periods of plasticity:
1. Infancy (0–3 years)
2. Adolescence (newer discovery)
Plasticity means the brain:
o Changes in response to active learning and passive exposure.
o Is highly influenced by environment (both positive and negative).
o Can benefit from education but is also more vulnerable to harm
Risks of Heightened Plasticity
Adolescents’ brains are especially sensitive to:
o Substance use (alcohol, nicotine, drugs)
o Physical injury (e.g. sport-related concussion)
o Psychological stress or trauma
These influences may lead to permanent damage or issues in adulthood (e.g., anxiety,
depression, poor impulse control).
PHYSICAL DEVELOPMENT: Contact Sports and Mild Traumatic Brain Injury (MTBI)
Rugby, a popular contact sport in South Africa, is linked with:
o MTBI – caused by blows to the head (even if “mild”).
o Symptoms: confusion, disorientation, short-term memory loss.
o Long-term consequences: memory problems, depression, and increased health
risks.
South African Studies:
Basson et al. (2017): Rugby players showed reduced executive functioning compared
to those in non-contact sports.
o Executive functioning includes: planning, memory, impulse control,
motivation, emotional regulation.
Similar findings by Nel et al. (2017) and Shuttleworth-Edwards et al. (2007).
Other sports like boxing and soccer also show MTBI risks.
o In the U.S., ~50% of youth sport-related brain injuries come from contact
sports.
PHYSICAL DEVELOPMENT: The influence of gender on brain development
What the Research Says:
The media often claims big differences between male and female brains.
157
But scientific evidence shows:
o Gender differences in brain structure and function are small.
o Some areas are slightly larger in females, others in males, but overall the
similarities outweigh the differences.
o These structural differences do not clearly explain behavioural or cognitive
differences between the sexes.
Hormones and Brain Development:
Sex hormones (e.g., testosterone, oestrogen) do affect brain development.
However, how these hormonal effects influence behaviour or thinking is still not well
understood.
Sexual maturation, also known as puberty, is a major physical and psychological
process during adolescent development.
Sexual maturity is the stage when an individual can reproduce.
The main hormones responsible for sexual maturation are sex hormones, also called
gonadal hormones or gonadotrophin.
These hormones are secreted by the pituitary gland, which is connected to the
hypothalamus in the limbic system of the brain.
Gonadotrophin stimulates the gonads (testes in males, ovaries in females) to release
male and female sex hormones.
Male sex hormones are called androgens, with testosterone and androsterone being
the most important.
Males also produce small amounts of oestrogen.
Female sex hormones are called oestrogens (or oestrogen).
Androgen and oestrogen lead to the development of primary and secondary sex
characteristics.
o Primary sex characteristics: Reproductive organs (penis, testes, vagina, uterus,
ovaries).
o Secondary sex characteristics: Physical traits that develop during puberty but
are not directly involved in reproduction.
Males: Body hair (beard, pubic, chest) and deeper voice.
Females: Breasts and pubic hair.
Puberty involves complex, integrated changes in body, brain, behaviour, cognition,
and emotion.
Puberty is starting earlier than in the past, a pattern known as the secular trend.
The secular trend may be due to:
o Healthier diets
o Better medical care
o Improved hygiene
o Fewer childhood diseases (due to immunisation)
Puberty begins about two years earlier in girls than in boys.
Table 6.1 provides examples, but individual and group variations exist.
A Western Cape study found delayed puberty in boys compared to boys from other
regions.
o Delays were linked to nutrition, socio-economic status, and environmental
factors.
Another South African study found that height and body mass in early childhood
predicted the onset of puberty.
pg 160
PHYSICAL DEVELOPMENT: Sexual maturation in girls
Primary sex characteristics
Primary sex organs begin to enlarge: ovaries, uterus, vagina, labia, clitoris
Secondary sex characteristics
First visible sign: appearance of breast buds
Growth of pubic and underarm hair
Broader hips, accumulation of body fat, slight voice deepening, skin texture changes
Menarche (First Menstruation)
Physical and Emotional Impact
o Symbolic and dramatic marker of sexual maturity
o Emotional responses can be mixed:
Positive: increased social maturity, peer prestige, self-esteem, body
awareness
Negative: self-consciousness, discomfort, backaches, cramps, possible
shame due to societal reactions (Anjum et al., 2018)
Cultural and Individual Differences
Reactions shaped by preparation and culture
E.g., Batswana girls show pride in physical changes (Mwamwenda,
1995)
Western girls may feel shy or uncomfortable
Cultural rituals and ambivalence:
Traditions like intonjane and inkciyo (Xhosa, Zulu, Shona cultures)
Some women feel pride and discomfort simultaneously
(Padmanabhanunni et al., 2018)
Timing of Menarche
Average Onset
o Globally and in South Africa: 12–13 years (Ramathuba, 2015; Paterson, 2016)
o Range considered normal: 11 to 15 years
Sequence
o Menarche typically occurs:
2–3 years after breast development and uterine growth
After the growth spurt slows (Maher et al., 2018)
Factors Influencing Age at Menarche
Biological and Environmental
o Influenced by pre-pubertal socio-economic status (Said-Mohamed et al., 2018)
Physical Activity
o Intense exercise (e.g., athletes) may delay menstruation up to 18 years
Psychosocial Factors
o Stressful experiences (e.g., family conflict, father absence) may lead to earlier
menarche (Tither et al., 2008)
Socio-Economic Status
o Higher socio-economic status → earlier menarche than in lower SES groups
(Dey et al., 2020)
Fertility and Ovulation Post-Menarche
Most girls begin to ovulate regularly 1–2 years after menarche
However, some may ovulate immediately → risk of pregnancy if sexually active
(Carlson et al., 2019)
Puberty Rituals and Cultural Responses
Modern vs Traditional Societies
o In urban/Westernised cultures → puberty seen as unremarkable
o In traditional/rural societies → marked by rituals, feasts, and initiation rites
Female Circumcision (FGM)
o Practised in ~30 countries, including parts of South Africa
o Affects 200 million+ women globally (WHO, 2020)
Types of Female Genital Mutilation (FGM)
Clitoridectomy
o Partial/total removal of the clitoris
Excision
o Removal of clitoris + labia minora, sometimes labia majora
Infibulation
o Removal of all external genitalia; vaginal opening stitched, only opened by
husband
Other harmful practices
o Piercing, pricking, scraping, burning, etc., for non-medical purposes (NHS,
2019; WHO, 2020)
Description of FGM Practices
FGM is traditionally performed by elderly women or traditional healers without
anaesthesia or antiseptics.
Implements used include razor blades, knives, scalpels, and even glass.
Immediate risks: extreme pain, bleeding, infection, shock, difficulty urinating, and
death.
Long-term complications: chronic pain, childbirth issues, anxiety, frigidity, and
infertility.
Cultural Beliefs and Justifications
Rooted in cultural and moral beliefs such as:
o Clitoris contains “poison” harmful to men and babies.
o Removing the clitoris enhances fertility and affirms femininity.
o Avoids the clitoris “growing into a penis.”
Seen by some as a rite of passage into womanhood (e.g., Venda’s nonyana hut and the
branding ceremony).
pecific Cultural Examples
Venda: Postnatal FGM (muthuso) uses vaginal flesh in traditional medicine to treat
goni.
Basotho baTlokwa: Defend the practice as voluntary and tied to cultural identity and
dignity.
Opposition to FGM
Human rights activists: Highlight its brutality, pain, and health risks.
FGM is illegal under South African law (Children’s Act 38 of 2005).
Some view it as gender-based violence carried out under the guise of tradition.
Challenges to Ending FGM
Strong resistance from traditional leaders who see state laws as cultural interference.
Deeply entrenched societal norms make it difficult for uncircumcised women to
marry or gain social acceptance.
Viewed as an expression of identity and womanhood, making eradication complex.
Critical Reflections
Human rights vs. cultural rights: The tension between protecting bodily autonomy and
respecting cultural traditions.
Informed consent and agency: Even when claimed to be voluntary, social pressure
may compromise true choice.
Health consequences vs. identity: Tradition must be weighed against scientific
evidence of harm and the rights of women and girls.
Legal enforcement: The gap between policy and practice due to cultural resistance
and community secrecy.
PHYSICAL DEVELOPMENT: Sexual maturation in boys
Primary sex characteristics
Puberty begins with the development of the testes and scrotum, followed by penis
enlargement.
Secondary sex characteristics
These include pubic and armpit hair, beard growth, and voice deepening (due to vocal
cord and larynx changes).
Semenarche (first ejaculation): Marks a major milestone in male sexual maturation,
typically occurring between ages 13 and 15.
Psychological Reactions to Puberty
Most boys welcome these physical changes, although some may feel embarrassed,
particularly about spontaneous erections or voice changes.
Adolescents who are prepared for these changes cope better and report more positive
experiences.
Early or late maturation can affect self-esteem and peer relationships.
Traditional Male Circumcision
Practiced in certain African cultures (e.g., among the Xhosa) as a rite of passage into
manhood.
Involves ritual sacrifice, seclusion, circumcision, and symbolic practices like
smearing with white clay and burning of personal belongings.
While culturally important, it has led to serious health risks including infection,
mutilation, gangrene, and even death due to unqualified practitioners and poor
hygiene.
Despite legal and health concerns, many boys still prefer traditional circumcision due
to its cultural significance.
Legal and Health Concerns
The Children’s Act (No. 38 of 2005) in South Africa prohibits harmful practices.
Researchers recommend culturally sensitive negotiations instead of confrontational
strategies.
Successful models like Zimbabwe’s partnership with the Varemba show that blending
tradition with medical safety can work.
Psychological Effects of Physical Changes
Adolescents may struggle to accept their new appearance.
Girls may worry about weight gain, especially in cultures that idealize thinness.
Cultural differences affect body image—some African cultures view increased body
fat positively.
Early or late maturation can influence self-perception and mental health.
Nelson Mandela’s Experience
Mandela’s reflection on burying his foreskin during initiation captures the symbolic nature of
the ritual, marking the end of childhood and the beginning of manhood.
The psychological effects of physical changes
Adolescents and Body Changes
Adolescents become very self-aware of their bodies as they change.
One major task is to accept these physical changes, which can be difficult for many.
Asynchronous growth (when body parts grow at different rates) can make teens feel
clumsy.
Gender-Specific Concerns
Boys may feel embarrassed when their voice cracks or lowers.
Girls often worry about sudden weight gain.
o In Western cultures, thinness is preferred.
o In some African cultures, body fat can symbolize health and wealth.
Psychological Impact of Maturation Timing
The age at which puberty occurs matters for mental well-being.
Early-maturing adolescents:
o Tend to be taller and heavier earlier than peers.
o Girls may face mental health risks (e.g., depression, early risky behaviour).
o Boys may be seen as more popular or athletic, but may also face behavioural
issues (e.g., delinquency).
Late-maturing adolescents:
o Are smaller and lighter, and may feel left out or develop insecurities.
Cultural Context Matters
In some African communities, early development can bring respect and social status,
unlike in Western settings.
Mandela’s initiation story reflects how traditional practices mark the transition from
childhood to adulthood, symbolizing the burial of youth.
Long-Term Impact
Some effects of early or late maturation may continue into adulthood.
However, not all researchers agree that these effects last long-term.
Body Image and Adolescence
Definition: Body image is how one perceives, thinks, feels, and behaves toward their
body.
Influencing factors:
o Media
o Peers
o Romantic partners
o Cultural beliefs/ideals
Developmental changes affecting body image:
o Weight, height, body shape, body composition
o Primary and secondary sex characteristics
Negative body image risks:
o Unhealthy eating habits
o Eating disorders
Eating Disorders
Anorexia Nervosa
Definition: Refusal/inability to maintain normal body weight.
168
Serious mental health disorder; can be life-threatening.
Characteristics:
o BMI below 18.5; lower levels indicate severity
o Purging: vomiting, laxatives, over-exercise, drug use
o Distorted body image
o Often co-occurs with depression, anxiety, bulimia
o Physical symptoms: fine body hair, amenorrhea
Demographics:
o Most common between puberty and 25
o 90% of sufferers are adolescent females
o High achievers, low self-esteem, feelings of isolation
o 10–20% die; 50% never recover
Bulimia Nervosa
Definition: Binge eating followed by compensatory behaviours to avoid weight gain.
Characteristics:
o Self-induced vomiting, laxatives, fasting, exercise
o Not necessarily underweight
o Over-concern with body image and weight
Demographics:
o Peaks in late adolescence/early adulthood
o 1–3% prevalence in young females; ~0.1–0.3% in males
o Can begin as young as age 5
169
Cultural trend: Historically Western, now spreading globally due to
media/globalisation
Causes of Eating Disorders
Multifactorial causes:
o Environmental and genetic
o Interaction of individual and contextual factors
Psychological risk factors:
o Depression, anxiety, substance abuse
o Low self-esteem, early puberty, family strain
o Social pressures (e.g. dating)
Gender and identity considerations:
o Less research on males
o Boys may strive for muscularity—risking steroid use
o Transgender individuals also at higher risk
o Body dissatisfaction → unhealthy weight control → depression
Obesity
Definition: Excessive fat accumulation harmful to health
BMI Classifications:
o 25–30: Overweight
o 30–35: Moderately obese
o 35–40: Severely obese
170
o 40: Morbidly obese
Consequences:
o Affects cardiovascular, respiratory, gastrointestinal, musculoskeletal systems
o May cause infertility in females
o Leads to psychological issues: low self-esteem, anxiety, peer problems
Obesity in South African Adolescents
Trends:
o High and rising prevalence in rural and urban areas
o Females more at risk
Cultural influences:
o Some groups associate obesity with health
o Preferences for female body shape vary by region and context
Normal BMI for sisters/mothers (health reason)
Overweight for girlfriends/wives (sex appeal)
Implications:
o Cultural beliefs can conflict with health realities
o Globalisation reducing cultural differences in body ideals
Recommendations:
o Public health messaging should be gender- and age-appropriate
o Leverage social marketing to promote healthy weight
Contributing Factors to Adolescent Obesity
Environmental and lifestyle:
o Increased intake of unhealthy foods
171
o Sedentary lifestyles
Cultural and sociological:
o Body image ideals
o Misconceptions about health
Biological/genetic:
o Hormonal, neural, metabolic systems
Adolescent sexuality
During puberty, adolescents undergo significant physical changes that heighten their
awareness of their sexuality. This newly developed sexuality becomes a key part of their
identity and relationships. Adolescents also begin to explore and understand their sexual
orientation. A major developmental task at this stage is learning to express their sexual needs
in socially acceptable ways that support their identity formation.
Changing values and adolescent sexuality
Influence of Social Factors on Sexual Activity
Sexual activity is a natural result of physical development.
Social and cultural factors shape how sexuality is expressed.
Cultures aim to direct sexual behaviour in healthy ways to avoid:
o Physical issues (e.g., STDs like HIV/AIDS, syphilis)
o Psychological issues (e.g., obsession with sex interfering with education)
o Social issues (e.g., unwanted pregnancy, sexual exploitation)
Historical Perspective in Europe
In medieval Europe, early teenage marriage helped manage adolescent sexuality.
In 19th-century European Christian culture:
o Emphasis was on suppressing adolescent sexuality.
o Sexual feelings and behaviours (e.g., masturbation) were made to feel
shameful.
o A double standard existed: adults preached sexual restraint but didn’t always
follow it.
o Religion increased guilt and ambivalence around premarital sex.
o This led to:
Sexual dysfunction in adulthood
Secretive or rebellious sexual exploration
Traditional African Approaches
In many traditional African societies:
o Sexual exploration (not intercourse) was accepted and encouraged.
o Xhosa, Zulu, and Sotho cultures taught:
Boys: engage in non-penetrative sexual activity.
Girls: prevent penetration (e.g., by closing legs tightly).
o Practices included intercrural sex:
Called ukumetsha (Xhosa), ukuhlobonga (Zulu).
o Girls were traditionally checked to confirm virginity.
o Penetrative sex was forbidden before marriage.
Modern Influences and Shifts
Medical advances (e.g., contraception, STD treatment) encouraged sexual
permissiveness.
1960s: increase in premarital sex tolerance and reduction in gender-based double
standards.
Resulted in clashing values:
o Traditional sexual restriction vs. modern sexual freedom.
Impact of Westernisation and Urbanisation
Decline in traditional practices due to:
o Urbanisation
o Reduced parental control
Contributed to rising teenage pregnancies in South Africa.
Current Challenges and Mixed Messages
Adolescents receive conflicting guidance:
o Parents/authority figures discourage sex but offer little information.
o Peers and media become main sources of sexual knowledge.
Media often portrays sex:
o As spontaneous, romantic, and passion-driven.
o With little regard for emotional, contraceptive, or health consequences.
Types of Adolescent Sexual Behaviour
Autoerotic behaviour (masturbation):
o Common first sexual experience, even from childhood.
o Historically viewed negatively (immoral, sinful, harmful).
o Now considered normal and healthy unless it interferes with social life.
174
o Still some anxiety due to cultural and parental attitudes.
o More common among males than females (up to 95% of males, 75% of
females by late adolescence).
Interactive sexual activities (e.g. kissing, cuddling, intercourse):
o Shift in societal norms from the 1960s sexual revolution.
o Influenced by early puberty, peer pressure, media, and contraceptives.
- Early sexual maturation. As mentioned earlier, puberty
develops at an earlier age, with the result that adolescents
become sexually mature at an earlier age.
- Peer-group pressure. Because of certain attitudes of, and
pressures from their peer group, adolescents may be under the
impression that they are not “normal” if they are not sexually
active. Therefore, they become sexually active to be accepted
by their peer group. In fact, one of the strongest predictors of
sexual activity in adolescents is whether their friends are
sexually active.
- Changed values, attitudes, and the media. As mentioned before,
changed values, attitudes, the mass media, and even sexual
content in adolescents’ music contribute to the fact that
adolescents experience the world as sexually active and even
sexually preoccupied. This inevitably had the effect that
adolescents began to see sexual activity as more acceptable
than previous generations did.
- Contraceptives. The invention and availability of a reliable oral
contraceptive (‘the Pill’) during the sexual revolution took away
the fear of getting pregnant and thus defused a preventative
factor that had been very important in previous generations.
o WHO reports later initiation of sexual activity in 2020, possibly due to
technology and STD fears.
o Rates vary across cultures and countries.
175
o In South Africa:
Over 1/3 of females and 50% of males are sexually active.
Average age of first sex: 15 for females, 14 for males.
60% of females report coerced first experience.
Male adolescents report more sexual partners.
Key Influencing Factors in South Africa
Lack of Parental Involvement:
o Parents are vital for healthy sex education but often avoid the topic.
o Adolescents turn to peers or unreliable sources, leading to myths and
misinformation.
o Sex education should go beyond biology to include relationships, consent,
identity, and safe practices.
Peer Influence:
o Peers and admired figures heavily impact sexual behaviours.
o Adolescents conform to perceived norms, even if harmful.
o Fear of rejection can override awareness of risk.
Substance Abuse:
o Alcohol and drugs linked to early sexual debut and risky sexual behaviour.
o Alcohol impairs judgement and increases risk-taking.
o Beliefs about alcohol’s effects influence actions (e.g., not using protection
when drinking).
o According to the alcohol myopia theory (i.e., short-sightedness), the intense
disinhibitory effects of alcohol reduce the ability to process complex
information (such as long-term goals), thus allowing immediate goals (such as
sexual arousal) to influence behaviour more strongly.
o Alcohol expectancy theory claims that the nature of one’s beliefs, as well as
the strength of these beliefs, influences the effect of alcohol on subsequent
high risk sexual behaviour
Overcrowding:
o Housing shortages and informal settlements reduce sexual privacy.
o High sleeping density contributes to exposure to sexual behaviours and early
sexual experiences.
Adolescent pregnancy
Global and South African Adolescent Pregnancy Statistics
Each year, 21 million girls aged 15–19 in developing countries become pregnant, with
12 million giving birth.
Around 800,000 births are to girls under 15.
Pregnancy complications are the leading cause of death for 15–19-year-olds.
Of 6 million adolescent abortions annually, 4 million are unsafe, causing serious
health risks.
Babies of teen mothers face higher risks like low birth weight and preterm delivery.
In South Africa, 15–20% of mothers had their first child as adolescents.
Causes of Adolescent Pregnancy
Early sexual activity and low/no contraceptive use are key factors.
Many adolescents do not use contraceptives despite their availability.
Psychological and Personality Factors Influencing Non-Use of Contraceptives:
High external locus of control – they believe events happen beyond their control.
Low self-efficacy and self-esteem – lack of confidence in managing their behaviour
and decisions.
Other Contributing Reasons:
Unplanned sexual encounters.
Guilt or denial about being sexually active.
Cultural beliefs about fertility.
Adolescent egocentrism and “invincibility” mindset.
Embarrassment to seek contraceptives.
Misconceptions About Child Support Grants
It is a myth that teens fall pregnant to receive grants.
Studies show:
o Grants are too small to be an incentive.
o No increase in teen pregnancies after grants were introduced.
o Teen pregnancies are high in countries with no grants.
o Rates are declining despite the grants.
Consequences of Teenage Pregnancy
Emotional and social immaturity leads to poor readiness for parenthood.
Can cause a chain reaction of negative impacts across generations.
Psychological effects include depression, anxiety, isolation, and low life satisfaction.
178
Adolescent mothers often struggle to return to school, face economic hardship, and
experience inferiority compared to peers.
Long-Term Outcomes (Anakpo et al., 2019; Johansen et al., 2020)
Negative effects of adolescent motherhood can last decades.
Those from privileged backgrounds may suffer more due to lost opportunities.
Fathers often experience fewer negative outcomes due to age, employment, and
societal norms.
Marriage or cohabitation may reduce stigma and provide more stability.
Broader Public Health Implications
High-risk sexual behaviour also increases the risk of STIs like HIV, syphilis, and
herpes.
A multidisciplinary approach involving families, schools, communities, and
policymakers is essential to address the issue.
Understanding Sexual Orientation
Definition: Sexual orientation is a person’s romantic and sexual attraction to a
specific gender.
Prevalence: Around 95% of people globally identify as heterosexual.
Hidden identities: Over 80% of non-heterosexual individuals hide their orientation
due to fear of discrimination.
Misconceptions: Sexual activity is not a requirement for identifying with a particular
sexual orientation.
Gayness: Research and Social Context
Heavily researched but controversial: Gayness is the second most studied orientation
after heterosexuality but also the most debated, causing family, religious, and political
conflict.
Historical context: Homosexuality was labeled a mental disorder until 1973.
Legal and societal acceptance: Many countries accept gay rights (e.g., South Africa),
but ~70 countries criminalize homosexual acts, often on religious or cultural grounds.
Misconception: Some countries and religious groups wrongly believe sexual
orientation is a personal choice and “un-African.”
Terminology and Language
Importance of terminology: Language shapes perceptions. Using sensitive, accurate
terms avoids discrimination.
Issues with “homosexual”: Seen as outdated, unclear, male-centred, and linked to past
pathologization.
Preferred terms: “Gay” for males, “lesbian” for females. “Same-sex” is used for
relationships.
Inclusive acronyms: LGBT evolved into LGBTQIA+ to represent a broader, diverse
group with unique identities and needs.
Adolescent Sexual Orientation Development
Self-discovery: Most people discover their orientation during adolescence.
Extra challenges for LGBTQ+ youth: Greater anxiety, fear, and risk of depression due
to discrimination.
“Gaycism” vs. “Homophobia”: The term “gaycism” is proposed to better capture
systemic discrimination against LGBTQ+ individuals.
Concealment: Many adolescents pretend to be heterosexual due to fear, leading to
emotional distress.
oices of Gay Adolescents
Examples shared: Show deep emotional struggles, fear of rejection, and eventual self-
acceptance.
Insight: Not all gay adolescents cope the same—some accept themselves, others
experience severe mental health issues.
Prevalence and Exploration
Hidden identity skews statistics.
Estimated numbers: 5–10% of males and 2–5% of females may identify as gay.
Exploration ≠ Orientation: Same-sex experiences during adolescence don’t necessarily
indicate a gay orientation.
Causes of Gayness
Not a choice: This is supported by most researchers.
Challenging the “choice” idea: Gay people ask thought-provoking questions to
highlight that orientation is not chosen.
Rejected theories: Psychoanalytic theory (e.g., absent father) lacks support.
Current evidence supports biology:

COGNITIVE DEVELOPMENT
Adolescence is marked by significant cognitive changes alongside physical growth. As
adolescents’ bodies change, so does the way they think about themselves and the world. This
period sees growth in various thought processes, such as perception, memory, problem-solving, and reasoning. Adolescents begin to think more like adults, which influences how
they react to their changing social lives and relationships. While many cognitive challenges in
industrialized countries occur in schools, cognitive development impacts all areas of
adolescents’ lives. The prefrontal cortex continues to mature during this time, improving
higher-order functions like decision-making and planning, but full maturation happens only
in early adulthood.
