Quick review

CLEP Human Growth and Development Quick Review

High-impact topic boxes for a focused review session before you take the practice test.

1. Foundational Developmental Debates and Psychodynamic Theory

The big idea

Every developmental theory takes a position on recurring debates--nature vs.\ nurture, continuity vs.\ discontinuity--and psychodynamic theory frames development as driven by resolving internal conflict across fixed stages.

Must know

Freud's psychosexual stages (oral, anal, phallic, latency, genital) are driven by libido; the unconscious motivates behavior. The nature-nurture debate asks what source drives development; the continuity-discontinuity debate asks whether change is gradual or stage-like.

Don't confuse

Nature-nurture debate (source of development) vs.\ continuity-discontinuity debate (pattern of development).

Exam trap

Labeling any stage theory ``psychodynamic''--only Freud's and Erikson's theories belong to that tradition.

5-second recall

Debates first, then camp: nature/nurture $arrow$ continuity/discontinuity $arrow$ context.

2. Learning Theories and Social Cognitive Theory

The big idea

Learning theorists argue development results from experience, reinforcement, and observation rather than from internal stages.

Must know

Classical conditioning (Pavlov) pairs a neutral stimulus with an unconditioned stimulus. Operant conditioning (Skinner) shapes behavior through reinforcement and punishment. Bandura's social cognitive theory adds observational learning/modeling, reciprocal determinism (person-behavior-environment), and self-efficacy.

Don't confuse

Classical conditioning (stimulus association) vs.\ operant conditioning (consequence-shaped behavior) vs.\ observational learning (learning without direct reinforcement).

Exam trap

Treating modeling as identical to reinforcement--Bandura's Bobo doll studies showed learning can occur with no reinforcement to the observer at all.

5-second recall

Pavlov pairs, Skinner rewards, Bandura watches.

3. Ecological, Sociocultural, and Evolutionary Perspectives

The big idea

Development is also shaped by nested environmental systems, cultural transmission, and behaviors that persisted because they were adaptive.

Must know

The ecological perspective situates the individual within nested environmental contexts. The sociocultural perspective holds that culture and social interaction drive development. The evolutionary/ethological perspective explains behavior through adaptive value; Bowlby framed attachment as an evolved survival mechanism, and Lorenz demonstrated imprinting in goslings during a critical period.

Don't confuse

Critical period (a fixed window--the behavior may never develop if missed) vs.\ sensitive period (an optimal window--development can still occur later, just less easily).

Exam trap

Assuming ``ecological'' theory refers to environmental science rather than to a nested-systems model of context.

5-second recall

Systems $arrow$ Culture $arrow$ Adaptation.

4. Research Designs: Case Study, Correlational, and Experimental

The big idea

The design chosen determines what kind of claim--description, association, or causation--a study can actually support.

Must know

A case study gives an in-depth single-subject account with no generalizability. A correlational study measures the direction and strength of an association but cannot establish causation. An experiment manipulates an independent variable, controls confounds, and uses random assignment; it is the only design that supports causal claims.

Don't confuse

Correlation (variables co-occur) vs.\ causation (manipulation produces the change).

Exam trap

Assuming a strong correlation (e.g., $r = .80$) proves that one variable causes the other.

5-second recall

Describe $arrow$ Associate $arrow$ Cause: case study, correlational, experimental.

5. Developmental Research Designs: Longitudinal, Cross-Sectional, and Sequential

The big idea

Studying change over time forces a trade-off between time, cost, attrition, and cohort effects.

Must know

Longitudinal designs follow the same people over time, tracking true change but risking attrition and practice effects. Cross-sectional designs compare different age groups at one time--fast, but age is confounded with cohort. Cross-sequential (sequential) designs combine both by following multiple cohorts over time. Observational designs record naturally occurring behavior without manipulation.

Don't confuse

Cohort effect (a generational difference unrelated to age) vs.\ a true age/developmental effect.

Exam trap

Treating a cross-sectional study as if it shows individual change over time--it only compares different people once.

5-second recall

Same people over time = longitudinal; different ages once = cross-sectional; both combined = sequential.

6. Genetics, Heredity, and Genetic Disorders

The big idea

Genotype supplies the biological potential; phenotype is the observable outcome of genotype interacting with environment.

Must know

Humans have 23 pairs of chromosomes (22 autosomal + 1 sex pair). Dominant and recessive alleles follow predictable inheritance patterns. Down syndrome = trisomy 21; Klinefelter syndrome = XXY; Turner syndrome = X0; phenylketonuria (PKU) is a recessive metabolic disorder. Genetic counseling and prenatal testing (amniocentesis, chorionic villus sampling) screen for such conditions.

Don't confuse

Genotype (genetic makeup) vs.\ phenotype (observable expression, shaped by environment).

Exam trap

Assuming a dominant-gene condition must be more common than a recessive one--frequency depends on population genetics, not dominance status.

5-second recall

Genotype (code) $arrow$ environment (context) $arrow$ phenotype (expression).

7. Prenatal Development and Teratogens

The big idea

Prenatal development moves through three tightly sequenced stages, and vulnerability to teratogens depends on precise developmental timing.

Must know

Germinal stage (fertilization to about 2 weeks, includes implantation); embryonic stage (weeks 3-8, organogenesis--the period of greatest vulnerability); fetal stage (week 9 to birth, growth and maturation of already-formed structures). Teratogens include alcohol (fetal alcohol spectrum disorders), nicotine, certain medications, maternal infection (e.g., rubella), and radiation; effects depend on dose, timing, and the organ system developing at exposure.

Don't confuse

Embryonic stage (organ formation, highest teratogen risk) vs.\ fetal stage (growth of already-formed structures, generally lower structural risk).

Exam trap

Assuming any teratogen exposure causes damage regardless of trimester--the same substance can be harmless or catastrophic depending on timing.

5-second recall

Timing determines damage: organ forming = highest risk.

8. Physical Growth, Motor Development, and Puberty

The big idea

Motor development follows a predictable cephalocaudal (head-to-tail) and proximodistal (center-to-periphery) sequence, and puberty follows a hormonally triggered but individually variable timetable.

Must know

Gross motor skills (crawling, walking) precede fine motor refinement (grasping). Puberty is triggered by the hypothalamic-pituitary-gonadal (HPG) axis. Primary sex characteristics involve the reproductive organs; secondary sex characteristics (breast development, facial hair) do not. Menarche and spermarche mark reproductive maturation; the secular trend describes a historical shift toward earlier puberty onset.

Don't confuse

Primary sex characteristics (reproductive structures) vs.\ secondary sex characteristics (nonreproductive traits like body hair).

Exam trap

Treating the onset age of puberty as fixed--normal timing varies widely by individual and by sex.

5-second recall

Head-to-tail, center-to-out, hormones drive puberty.

9. Aging and Physical Change in Late Adulthood

The big idea

Aging is a gradual, multi-system biological process, and distinguishing normal aging from disease-driven decline matters.

Must know

Primary aging is normal, genetically influenced decline (e.g., slower reaction time, sensory decline). Secondary aging results from disease, lifestyle, or environmental factors. Menopause marks the cessation of menstruation and estrogen decline. Common late-life changes include presbyopia (vision) and presbycusis (hearing). Life expectancy (average years lived) differs from life span (the maximum biologically possible age).

Don't confuse

Primary aging (universal, ``normal'' decline) vs.\ secondary aging (disease- or lifestyle-driven, often preventable).

Exam trap

Attributing a treatable health problem in an older adult to ``just aging'' rather than to a secondary, addressable cause.

5-second recall

Normal wear = primary; disease/lifestyle = secondary.

10. Infant Sensory and Perceptual Capacities

The big idea

Infants are far more perceptually competent at birth than once believed, and their skills sharpen rapidly through experience.

Must know

Habituation is a decreased response to a repeated stimulus, used to test infant perception and memory; dishabituation is a renewed response to a new stimulus, proving discrimination. Vision is the least mature sense at birth and improves rapidly; hearing, taste, smell, and touch are comparatively well developed at or before birth. The visual cliff experiment tested infant depth perception.

Don't confuse

Habituation (interest fades to a familiar, repeated stimulus) vs.\ dishabituation (interest renews to a novel stimulus).

Exam trap

Assuming a lack of overt behavioral response means an infant cannot perceive a stimulus--habituation paradigms can reveal perception that behavior alone would miss.

5-second recall

Same $arrow$ bored (habituate); new $arrow$ interested again (dishabituate).

11. Sensitive Periods and Sensory Deprivation

The big idea

Perceptual systems typically need appropriately timed stimulation to develop normally, and prolonged deprivation during that window can leave lasting effects.

Must know

A sensitive period is a window when the nervous system is maximally receptive to a particular experience. Sensory-deprivation research (including clinical cases of congenital cataracts) shows that a lack of patterned input during the sensitive window can permanently impair later perceptual function, even after normal input resumes.

Don't confuse

Sensitive period (flexible, optimal window) vs.\ critical period (rigid, fixed deadline, as with imprinting).

Exam trap

Assuming any delay in stimulation is automatically permanent--outcomes depend on the system involved and how the deprivation's duration relates to the sensitive window.

5-second recall

Right input, right window = normal wiring.

12. Piaget's Stages of Cognitive Development

The big idea

Piaget argued children actively construct their understanding of the world by moving through qualitatively distinct, maturing stages of reasoning.

Must know

Sensorimotor (birth-2: object permanence); preoperational (2-7: symbolic thought, egocentrism, lacks conservation); concrete operational (7-11: conservation, reversibility, logical thought about concrete objects); formal operational (11+: abstract, hypothetical reasoning). Core mechanisms: schemas, assimilation (fitting new information into an existing schema), accommodation (changing a schema to fit new information), and equilibration.

Don't confuse

Assimilation (new information reshaped to fit an existing schema) vs.\ accommodation (a schema reshaped to fit new information).

Exam trap

Assuming everyone reaches formal operational reasoning, or reaches it at the same age--it is individually and culturally variable.

5-second recall

Sensorimotor $arrow$ Preoperational $arrow$ Concrete $arrow$ Formal: object $arrow$ symbol $arrow$ logic $arrow$ abstraction.

13. Vygotsky's Sociocultural Theory

The big idea

Vygotsky held that cognitive development is fundamentally a social and cultural process mediated by language and more skilled partners.

Must know

The zone of proximal development (ZPD) is the gap between what a learner can do alone versus with guided assistance. Scaffolding is adjustable support that a more skilled partner provides and gradually withdraws as competence grows. Private/inner speech is self-directed talk that guides thinking. Culture supplies psychological ``tools'' such as language and symbols.

Don't confuse

Piaget's view (the child as a solitary scientist constructing knowledge) vs.\ Vygotsky's view (the child develops through guided social interaction).

Exam trap

Describing scaffolding as simply giving the answer--effective scaffolding is calibrated support that fades as independence grows.

5-second recall

ZPD = the cannot-alone-but-can-with-help zone; scaffolding closes it.

14. Information Processing, Attention, and Memory

The big idea

The information-processing approach models cognition as interacting components--attention, memory stores, control processes--that grow more efficient with development.

Must know

Attention becomes more selective and sustained with age. Working memory capacity increases through childhood. Executive function includes inhibitory control, cognitive flexibility, and working memory, and continues developing into early adulthood. Metacognition is awareness/monitoring of one's own thinking. Memory strategies (rehearsal, organization, elaboration) improve with age.

Don't confuse

Working memory (actively holding/manipulating information) vs.\ long-term memory (stored, relatively permanent knowledge).

Exam trap

Assuming poor performance on a memory task reflects poor storage rather than poor retrieval or weak strategy use.

5-second recall

Attention filters $arrow$ memory stores $arrow$ executive function controls.

15. Problem Solving, Expertise, and Wisdom Across the Life Span

The big idea

Cognitive skill is not just raw processing speed--expertise and wisdom reflect accumulated, domain-specific and life experience that can offset age-related decline.

Must know

Expertise develops through extensive domain-specific practice and produces efficient, chunked problem solving. Fluid intelligence (novel-problem reasoning) tends to decline with age, while crystallized intelligence and wisdom (accumulated knowledge, practical judgment) tend to remain stable or increase. Play in childhood supports problem solving, planning, and social-cognitive skill.

Don't confuse

Fluid intelligence (speed/novel reasoning, declines with age) vs.\ crystallized intelligence (knowledge-based, wisdom-related, stable or increasing with age).

Exam trap

Assuming all cognitive abilities decline uniformly in older adulthood--vocabulary, expertise, and wisdom often hold steady or improve.

5-second recall

Fluid fades, crystallized (and wisdom) holds.

16. Early Language Milestones and Theoretical Explanations

The big idea

Language develops in a strikingly universal sequence, and theorists disagree about how much of that capacity is innate versus learned.

Must know

Cooing (about 2 months) $arrow$ babbling (about 6 months) $arrow$ first words (about 12 months) $arrow$ telegraphic/two-word speech (about 18-24 months) $arrow$ rapid vocabulary growth. Chomsky proposed an innate language acquisition device (LAD)/universal grammar; Skinner argued language is learned through reinforcement and imitation; interactionist views combine biological readiness with social input such as child-directed speech.

Don't confuse

Nativist view (biological, innate grammar capacity) vs.\ learning/behaviorist view (reinforcement and imitation shape language).

Exam trap

Treating babbling as meaningless noise--it reflects universal phonetic exploration and narrows toward the native language by about 10-12 months.

5-second recall

Coo $arrow$ babble $arrow$ word $arrow$ two-word $arrow$ grammar explosion.

17. Semantics, Syntax, and Pragmatics

The big idea

Language competence requires mastering meaning, structure, and appropriate social use all at once.

Must know

Semantic development is the growth of word meaning and vocabulary, including overextension (using ``dog'' for all animals) and underextension. Syntax governs how words combine into grammatical sentences, including overregularization of grammar rules (e.g., ``goed''). Pragmatics governs the social/contextual rules of language use, such as turn-taking and tone.

Don't confuse

Overextension (applying a word too broadly) vs.\ overregularization (applying a grammar rule too broadly, including to irregular forms).

Exam trap

Interpreting a grammar error like ``goed'' as poor language development--overregularization is actually evidence the child has learned a grammatical rule.

5-second recall

Meaning = semantics; structure = syntax; social use = pragmatics.

18. Bilingualism and Environmental Influences on Language

The big idea

Language development is powerfully shaped by the linguistic and cultural environment, and bilingual exposure has a distinct developmental profile.

Must know

Bilingual children may show a temporarily smaller vocabulary in each single language but comparable or superior overall linguistic, metalinguistic, and executive-function skills. Code-switching (alternating languages) is normal bilingual competence, not confusion. Language and thought interact (Vygotsky's view that language shapes thought via inner speech). Rich, responsive caregiver language input predicts stronger vocabulary growth.

Don't confuse

Code-switching (normal bilingual competence) vs.\ genuine language delay (an actual developmental concern).

Exam trap

Assuming bilingualism causes language delay--research generally shows no overall disadvantage, and often cognitive/executive-function benefits.

5-second recall

Two languages, one competent system.

19. Theories and Measurement of Intelligence

The big idea

Intelligence has been conceptualized both as a single general factor and as multiple distinct abilities, and tests translate these theories into scores.

Must know

Spearman proposed g, a general intelligence factor. Gardner proposed multiple intelligences (e.g., linguistic, logical-mathematical, spatial, musical, bodily-kinesthetic, interpersonal, intrapersonal). Sternberg's triarchic theory identifies analytical, creative, and practical intelligence. IQ tests (e.g., Stanford-Binet, Wechsler scales) yield standardized scores. Reaction range describes the genetically set boundaries within which environment shapes a trait's expressed level.

Don't confuse

Reliability (consistency of a test's results) vs.\ validity (whether the test measures what it claims to measure).

Exam trap

Treating an IQ score as fixed and purely genetic--reaction range shows environment meaningfully shapes outcomes within genetic limits.

5-second recall

One factor ($g$) vs.\ many factors (Gardner, Sternberg).

20. Giftedness, Stability, and Change in Intelligence

The big idea

Intelligence test performance shows both continuity and change across the life span, and giftedness and creativity are related but distinct from IQ.

Must know

Giftedness is typically defined by high IQ and/or exceptional domain-specific talent or creativity. Intelligence scores become more stable (better long-term prediction) as children grow older. The Flynn effect describes the observed rise in average IQ scores across generations. Creativity involves divergent thinking (many novel solutions), distinct from the convergent, single-answer thinking IQ tests emphasize.

Don't confuse

Convergent thinking (one correct answer, tested by IQ tests) vs.\ divergent thinking (many possible answers, associated with creativity).

Exam trap

Assuming a high-IQ child is automatically creative, or vice versa--the two correlate only moderately.

5-second recall

$g$ predicts convergent skill; creativity also needs divergent thinking.

21. Attachment Theory

The big idea

Attachment theory holds that the quality of an infant's early emotional bond with caregivers shapes a lasting internal working model for relationships.

Must know

Bowlby framed attachment as an evolved survival system. Ainsworth's Strange Situation identifies attachment styles: secure (distress at separation, comforted at reunion), avoidant (little distress, avoids caregiver at reunion), resistant/ambivalent (distress, not easily comforted at reunion), and disorganized (contradictory, confused behavior). Secure attachment is linked to caregiver sensitivity and responsiveness.

Don't confuse

Avoidant attachment (minimizes need for the caregiver) vs.\ resistant/ambivalent attachment (exaggerates distress, hard to soothe).

Exam trap

Assuming attachment style is permanently fixed at infancy and unaffected by later relationships or context.

5-second recall

Secure = comforted; avoidant = ignores; resistant = inconsolable; disorganized = confused.

22. Moral Development

The big idea

Moral reasoning develops through an invariant sequence of increasingly abstract standards for judging right and wrong, from consequence-based to principle-based thinking.

Must know

Kohlberg's levels: preconventional (reasoning based on punishment/reward), conventional (reasoning based on social approval, law and order), and postconventional (reasoning based on abstract, self-chosen ethical principles). Gilligan critiqued Kohlberg for underweighting a care-based, relationship-focused moral orientation relative to a justice-based orientation.

Don't confuse

Conventional level (conforms to social rules/laws) vs.\ postconventional level (may judge an unjust law by a higher ethical principle).

Exam trap

Assuming moral behavior always matches a person's moral-reasoning stage--people can reason at a high stage without always acting accordingly.

5-second recall

Punishment $arrow$ approval $arrow$ principle: pre $arrow$ conventional $arrow$ post.

23. Prosocial Behavior, Aggression, and Gender Development

The big idea

Social behavior develops through biological predisposition, cognition, and socialization together, producing both prosocial and aggressive patterns alongside gender understanding.

Must know

Prosocial behavior is voluntary behavior intended to benefit others (helping, sharing, comforting), predicted by empathy and perspective-taking. Aggression can be instrumental (goal-directed) or hostile/reactive (intent to harm), and physical or relational. Gender identity, gender roles, and gender schemas develop through biological, cognitive, and socialization processes.

Don't confuse

Instrumental aggression (a means to a goal, e.g., taking a toy) vs.\ hostile aggression (the goal is to harm).

Exam trap

Assuming aggression is purely biologically driven--socialization, modeling, and reinforcement strongly shape its expression.

5-second recall

Help = prosocial; goal-hurt = instrumental; intend-hurt = hostile.

24. Self-Concept and Social Cognition Across the Life Span

The big idea

Understanding of the self and of other minds becomes progressively more abstract, multidimensional, and socially embedded with development.

Must know

Self-concept shifts from concrete, physical descriptions in early childhood to abstract, psychological, comparative descriptions in adolescence. Theory of mind--the understanding that others hold distinct beliefs and perspectives--typically emerges around age 4, shown by false-belief tasks. Social cognition includes perspective-taking and social comparison, both growing more sophisticated with age. Identity development is a key task of adolescence.

Don't confuse

Self-esteem (an evaluative judgment of self-worth) vs.\ self-concept (a descriptive understanding of who one is).

Exam trap

Assuming young children who fail false-belief tasks are simply less intelligent--it reflects a specific theory-of-mind milestone, not general cognitive delay.

5-second recall

Self-concept describes; self-esteem evaluates; theory of mind = others think differently than I do.

25. Bronfenbrenner's Bioecological Model

The big idea

Bronfenbrenner argued that development is shaped by nested layers of environmental context, from immediate settings to broad cultural forces, all interacting over time.

Must know

Microsystem = immediate settings with direct contact (family, school). Mesosystem = connections between microsystems (e.g., home-school relationship). Exosystem = settings that affect the child indirectly, without the child's direct participation (a parent's workplace). Macrosystem = broad cultural values, laws, and customs. Chronosystem = the dimension of time and historical change.

Don't confuse

Microsystem (direct, immediate contact) vs.\ exosystem (indirect influence, no direct participation).

Exam trap

Mislabeling a parent's workplace stress affecting a child as a microsystem effect--the child has no direct contact with the workplace, making it an exosystem influence.

5-second recall

Micro $arrow$ Meso $arrow$ Exo $arrow$ Macro $arrow$ Chrono: near to far, now to history.

26. Parenting Styles and Family Structures

The big idea

Parenting style--the combination of warmth/responsiveness and control/demandingness--is consistently linked to differences in child outcomes.

Must know

Baumrind's styles: authoritative (high warmth, high control--associated with the best outcomes), authoritarian (low warmth, high control), permissive (high warmth, low control), and uninvolved/neglectful (low warmth, low control). Family structures (nuclear, single-parent, blended, extended, same-sex parent) vary in composition, but structure alone is a weaker predictor of outcomes than parenting quality and family process.

Don't confuse

Authoritarian parenting (strict, low warmth, demands obedience) vs.\ authoritative parenting (high standards paired with warmth and responsiveness).

Exam trap

Assuming any non-nuclear family structure is inherently harmful to development--research emphasizes family process (warmth, conflict, stability) over structure alone.

5-second recall

Warmth + control = authoritative (best); high control alone = authoritarian.

27. Abuse, Neglect, and Death and Dying Across the Life Span

The big idea

Family and social environments can profoundly disrupt development through maltreatment, and understanding death and loss is itself a developmental process.

Must know

Abuse/neglect can be physical, emotional, sexual, or neglect of basic needs; early maltreatment is linked to disrupted attachment and emotional/behavioral problems, moderated by risk and resilience/protective factors. Children's understanding of death (finality, irreversibility, universality) develops gradually and is typically not fully grasped until about age 7-10. K\"ubler-Ross proposed stages of grief (e.g., denial, anger, bargaining, depression, acceptance), though these are not a fixed, universal sequence.

Don't confuse

Risk factors (increase the likelihood of a poor outcome) vs.\ resilience/protective factors (buffer against adversity and promote positive outcomes).

Exam trap

Treating K\"ubler-Ross's stages as a rigid, universal, linear sequence everyone must pass through--grief responses vary widely by individual and culture.

5-second recall

Maltreatment raises risk; resilience factors buffer it.

28. Erikson's Psychosocial Stages

The big idea

Erikson proposed that personality develops across the entire life span through eight sequential crises, each resolved along a positive-negative continuum.

Must know

Trust vs.\ mistrust (infancy); autonomy vs.\ shame/doubt (toddlerhood); initiative vs.\ guilt (early childhood); industry vs.\ inferiority (school age); identity vs.\ role confusion (adolescence); intimacy vs.\ isolation (young adulthood); generativity vs.\ stagnation (middle adulthood); ego integrity vs.\ despair (late adulthood).

Don't confuse

Identity vs.\ role confusion (the adolescent task of forming a coherent self) vs.\ intimacy vs.\ isolation (the young-adult task of forming close, committed relationships).

Exam trap

Confusing Erikson's psychosocial (social, lifespan) stages with Freud's psychosexual (biological drive, childhood-only) stages--the names and age ranges differ.

5-second recall

Trust $arrow$ Autonomy $arrow$ Initiative $arrow$ Industry $arrow$ Identity $arrow$ Intimacy $arrow$ Generativity $arrow$ Integrity, birth to death.

29. Freud's Psychosexual Theory and the Structure of Personality

The big idea

Freud held that personality forms in early childhood as psychic energy (libido) focuses on a sequence of bodily zones, and that unconscious conflict among personality structures drives behavior.

Must know

Oral, anal, phallic, latency, and genital stages; fixation is an unresolved conflict at a stage that shapes adult personality. Id operates on the pleasure principle (unconscious drives); ego operates on the reality principle (mediates); superego is the internalized moral standard. Defense mechanisms (e.g., repression, denial, projection) protect the ego from anxiety.

Don't confuse

Id (seeks immediate gratification) vs.\ superego (internalized moral conscience) vs.\ ego (reality-based mediator between the two).

Exam trap

Applying Freud's stage terminology to social/relational development--Freud's stages describe the focus of libido, not social tasks (that is Erikson's framework).

5-second recall

Id wants it now, superego says no, ego finds a way.

30. Temperament and Emotional Development

The big idea

Infants show early, biologically based individual differences in temperament that interact with caregiving to shape later emotional and personality development.

Must know

Thomas and Chess identified temperament types: easy, difficult, and slow-to-warm-up. Goodness of fit--the match between a child's temperament and the caregiving environment--predicts adjustment. Basic emotions (joy, anger, fear, sadness) emerge early; self-conscious emotions (pride, shame, guilt, embarrassment) emerge later, once self-awareness develops. Emotion regulation improves substantially across childhood.

Don't confuse

Temperament (early, biologically based behavioral style) vs.\ personality (a broader, later-developing pattern shaped by temperament plus experience).

Exam trap

Assuming a ``difficult'' temperament guarantees poor outcomes--goodness of fit with caregiving matters more than temperament type alone.

5-second recall

Temperament is the raw wiring; goodness of fit determines the outcome.

31. Applying Developmental Principles: Learning Styles and Educational Interventions

The big idea

Translating developmental theory into educational and clinical practice requires matching interventions to a person's developmental level and needs.

Must know

Operant conditioning principles (reinforcement, shaping, extinction) underlie many classroom-management and behavioral intervention programs. Early, sustained intervention (e.g., high-quality preschool/day care) can improve outcomes for at-risk children. Individualized programs address specific learning disabilities. Role transitions (e.g., entering school, retirement) are supported by preparation and structured assistance.

Don't confuse

Intervention (proactive support to improve outcomes) vs.\ remediation delivered only after a problem becomes severe.

Exam trap

Assuming one intervention approach benefits all children equally regardless of developmental stage or individual needs.

5-second recall

Match the intervention to the developmental level, not the other way around.

32. Occupational Development and Retirement

The big idea

Work identity develops gradually across adolescence and adulthood, and retirement is a major, often gradual, developmental transition rather than a single event.

Must know

Vocational identity and exploration typically develop through adolescence and early adulthood as part of broader identity formation. Retirement involves adjusting to the loss of a work role, income change, and restructured daily routine and social contact. Preparation and continued social engagement predict better retirement adjustment.

Don't confuse

Chronological retirement age (a legal/institutional marker) vs.\ psychological adjustment to retirement (an ongoing developmental process).

Exam trap

Assuming retirement is uniformly experienced as a negative life event--reactions vary widely based on preparation, choice, health, and social support.

5-second recall

Work identity builds through adulthood; retirement is a transition, not an endpoint.

33. Neurodevelopmental and Behavioral Disorders

The big idea

Developmental psychopathology studies how normal developmental processes go awry, using standardized diagnostic criteria to distinguish disorders from typical variation.

Must know

CLEP questions follow DSM-5 terminology. Attention-deficit/hyperactivity disorder (ADHD) involves persistent inattention and/or hyperactivity-impulsivity that impairs functioning. Autism spectrum disorder (ASD) involves persistent deficits in social communication/interaction plus restricted, repetitive behaviors. Learning disabilities are specific difficulties in one domain (e.g., reading, math) despite otherwise typical ability. Intellectual disability involves significant limitations in both intellectual functioning and adaptive behavior with onset during the developmental period.

Don't confuse

Learning disability (a specific academic-skill deficit with average or above general intellect) vs.\ intellectual disability (broad limitation across intellectual and adaptive functioning).

Exam trap

Assuming ASD is defined mainly by intellectual impairment--it is defined by social-communication and restricted/repetitive-behavior criteria; intellectual ability varies widely across the spectrum.

5-second recall

ADHD = attention/activity; ASD = social + repetitive; LD = specific skill; ID = broad functioning.

34. Internalizing Disorders, Antisocial Behavior, and Cognitive Disorders of Aging

The big idea

Psychopathology across the life span ranges from internalizing distress to externalizing conduct problems to progressive cognitive decline in later life.

Must know

Anxiety and mood disorders (e.g., depression) are internalizing disorders marked by distress directed inward. Antisocial behavior violates others' rights; asocial behavior involves withdrawal. Fears, phobias, and obsessions are anxiety-related; trauma-based syndromes (e.g., PTSD) follow exposure to a traumatic event. Dementia is a cognitive disorder marked by significant, progressive decline in memory and other cognitive functions that interferes with daily functioning--distinct from normal age-related memory change.

Don't confuse

Normal age-related forgetfulness (mild, non-progressive) vs.\ dementia (progressive, functionally impairing cognitive decline).

Exam trap

Assuming every memory complaint in an older adult indicates dementia--normal aging includes some slowing without functional impairment.

5-second recall

Inward distress = internalizing; outward violation = antisocial; progressive memory loss = dementia, not normal aging.
