Lifespan Developmental Psychology: Final Exam Review

Learning Disabilities, Intellectual Disabilities, Gifted and Talented

Understanding the spectrum of cognitive abilities is essential in developmental psychology. Learning disabilities refer to neurological disorders that affect the brain's ability to receive, process, store, and respond to information. Intellectual disabilities are characterized by significant limitations in intellectual functioning and adaptive behavior. Gifted and talented individuals demonstrate exceptional abilities or potential in one or more domains.

Learning Disabilities: Dyslexia, dyscalculia, and dysgraphia are common types.
Intellectual Disabilities: Diagnosed by IQ below 70 and deficits in adaptive functioning.
Gifted and Talented: IQ above 130 or outstanding performance in specific areas.
Example: A child with dyslexia may struggle with reading but excel in mathematics.

Research Methods in Developmental Psychology

Research in psychology utilizes various methods to study human development across the lifespan.

Survey Research: Collects data from large groups using questionnaires.
Naturalistic Observation: Observes subjects in their natural environment without intervention.
Experimental Design: Manipulates variables to determine cause and effect.
Case Study: In-depth analysis of an individual or group.
Longitudinal Studies: Follows the same subjects over time.
Cross-Sectional Studies: Compares different groups at one point in time.
Correlational Studies: Examines relationships between variables.
Variables: Independent variable (manipulated), dependent variable (measured).
Interpretation of Correlation: Correlation does not imply causation; p-values indicate statistical significance.
Example: A longitudinal study tracking cognitive development from childhood to adolescence.

Brain Plasticity and Hemispheric Differences

Brain plasticity refers to the brain's ability to change and adapt as a result of experience. The left hemisphere is typically associated with language and analytical tasks, while the right hemisphere is linked to spatial and creative functions.

Plasticity: Most pronounced in childhood; allows recovery from injury.
Hemispheric Specialization: Left = language, Right = spatial abilities.
Example: Children can recover language abilities after left hemisphere damage more easily than adults.

Nature vs. Nurture

The nature vs. nurture debate explores the relative contributions of genetics (nature) and environment (nurture) to human development.

Nature: Genetic inheritance, biological factors.
Nurture: Environmental influences, learning, culture.
Example: Twin studies help disentangle genetic and environmental effects.

Critical/Sensitive Periods of Development: Language

Critical periods are specific times during development when certain skills or abilities are most easily acquired. Language acquisition is most effective during early childhood.

Critical Period: Time when exposure to stimuli is essential for normal development.
Example: Children deprived of language before age 7 may never fully develop normal language skills.

Effects of Caregivers on Children

Caregivers play a crucial role in shaping children's emotional, social, and cognitive development.

Attachment: Secure attachment leads to better social and emotional outcomes.
Parenting Styles: Authoritative, authoritarian, permissive, and uninvolved.
Example: Children with responsive caregivers tend to develop secure attachments.

Piaget's Theory of Cognitive Development

Jean Piaget proposed that children progress through four stages of cognitive development.

Sensorimotor (0-2 years): Learning through senses and actions.
Preoperational (2-7 years): Symbolic thinking, egocentrism.
Concrete Operational (7-11 years): Logical thinking about concrete events.
Formal Operational (12+ years): Abstract reasoning.
Example: Conservation tasks test children's understanding of quantity.

Attachment & Symptoms of Attachment Disorder

Attachment is the emotional bond between child and caregiver. Attachment disorders can result from neglect or inconsistent caregiving.

Secure Attachment: Child feels safe and confident.
Insecure Attachment: Avoidant, ambivalent, or disorganized.
Symptoms of Attachment Disorder: Difficulty forming relationships, lack of trust, emotional withdrawal.
Example: Reactive Attachment Disorder (RAD) in children from institutional settings.

Baumrind's Parenting Styles

Diana Baumrind identified three main parenting styles, each with distinct effects on child development.

Authoritative: High warmth, high control; best outcomes.
Authoritarian: Low warmth, high control; obedience but lower happiness.
Permissive: High warmth, low control; impulsive behavior.
Uninvolved: Low warmth, low control; poor outcomes.
Example: Authoritative parents set clear rules but are responsive to children's needs.

Kohlberg's Theory of Moral Development

Lawrence Kohlberg proposed a stage theory of moral reasoning.

Preconventional: Obedience and punishment, self-interest.
Conventional: Conformity, law and order.
Postconventional: Social contract, universal ethical principles.
Example: A child obeys rules to avoid punishment (preconventional).

Intelligence & Achievement Tests

Intelligence tests measure cognitive abilities; achievement tests assess knowledge in specific areas.

Intelligence Test: IQ tests (e.g., Wechsler, Stanford-Binet).
Achievement Test: Standardized exams in math, reading, etc.
Example: SAT is an achievement test; WAIS is an intelligence test.

Research on Gay & Lesbian Parenting

Studies show that children raised by gay or lesbian parents develop similarly to those raised by heterosexual parents.

Key Findings: No significant differences in emotional, social, or cognitive outcomes.
Example: Children of same-sex couples show normal adjustment and academic achievement.

Media Violence

Exposure to media violence can influence children's behavior and attitudes.

Effects: Increased aggression, desensitization to violence.
Moderators: Parental mediation, individual temperament.
Example: Children who watch violent TV may imitate aggressive behaviors.

Operant & Classical Conditioning

Classical conditioning involves learning through association; operant conditioning involves learning through consequences.

Classical Conditioning: Pavlov's dogs learned to associate a bell with food.
Operant Conditioning: Skinner's box demonstrated reinforcement and punishment.
Diagram Example:

Popular Children vs. Rejected & Neglected Children

Peer relationships are important for social development.

Popular Children: Well-liked, socially skilled.
Rejected Children: Disliked, may be aggressive or withdrawn.
Neglected Children: Neither liked nor disliked; often overlooked.
Example: Rejected children are at higher risk for behavioral problems.

Research in Divorce

Divorce can impact children's adjustment, but effects vary by age, temperament, and parental conflict.

Short-term Effects: Anxiety, behavioral issues.
Long-term Effects: Most children adjust over time, especially with supportive parenting.
Example: Children with high parental conflict pre-divorce may benefit from separation.

Primary vs. Secondary Aging

Primary aging refers to biological, inevitable changes; secondary aging results from lifestyle and environmental factors.

Primary Aging: Wrinkles, gray hair, reduced organ function.
Secondary Aging: Disease, poor health habits.
Example: Smoking accelerates secondary aging.

Erik Erikson's Psychosocial Theory

Erikson proposed eight stages of psychosocial development, each with a central conflict.

Trust vs. Mistrust (Infancy): Developing trust in caregivers.
Autonomy vs. Shame (Toddler): Developing independence.
Initiative vs. Guilt (Preschool): Asserting power and control.
Industry vs. Inferiority (School Age): Mastering skills.
Identity vs. Role Confusion (Adolescence): Forming personal identity.
Intimacy vs. Isolation (Young Adult): Forming relationships.
Generativity vs. Stagnation (Middle Adult): Contributing to society.
Integrity vs. Despair (Late Adult): Reflecting on life.
Example: Adolescents struggle with identity formation.

Personality: Big Five Factor Theory

The Big Five model describes personality using five broad traits.

Openness: Imagination, creativity.
Conscientiousness: Organization, dependability.
Extraversion: Sociability, assertiveness.
Agreeableness: Compassion, cooperativeness.
Neuroticism: Emotional instability.
Example: High conscientiousness predicts academic success.

Death and Dying

Developmental psychology examines attitudes toward death and the process of dying.

Kübler-Ross's Stages: Denial, anger, bargaining, depression, acceptance.
Bereavement: Grieving process varies by culture and individual.
Example: Hospice care focuses on quality of life at end of life.

Identity

Identity formation is a key developmental task, especially during adolescence.

Identity vs. Role Confusion: Erikson's stage for adolescence.
Factors: Family, peers, culture.
Example: Adolescents explore different roles before settling on an identity.

Moral Development

Moral development involves changes in reasoning about ethical issues.

Kohlberg's Stages: Preconventional, conventional, postconventional.
Influences: Parenting, culture, education.
Example: Adolescents begin to consider universal ethical principles.

Parenting Style	Warmth	Control	Outcomes
Authoritative	High	High	Best social, academic outcomes
Authoritarian	Low	High	Obedient, less happy
Permissive	High	Low	Impulsive, less self-control
Uninvolved	Low	Low	Poor outcomes

Big Five Trait	Description
Openness	Imaginative, curious
Conscientiousness	Organized, reliable
Extraversion	Outgoing, energetic
Agreeableness	Friendly, compassionate
Neuroticism	Moody, anxious
