    Study Notes

    Introduction to Developmental Psychology

    • Human Development is the systematic study of processes of change and stability throughout the life span, aiming to deal with internal and external conditions of existence.

    Goals of Human Development

    • Describe human behaviors
    • Explain why humans behave in certain ways
    • Predict human behavior
    • Intervene to influence human behavior as psychologists

    Domains of Development

    • Physical development
    • Cognitive development
    • Psychosocial development

    Periods of Life Span

    • Prenatal Period: Conception to birth
    • Infancy and Toddlerhood: Birth to age 3
    • Early Childhood: Age 3 to 6
    • Middle Childhood: Age 6 to 11
    • Adolescence: Age 11 to 20
    • Young Adulthood: Age 20 to 40
    • Middle Adulthood: Age 40 to 65
    • Late Adulthood: Age 65 and over, subdivided into:
      • Young Old: 65 to 74
      • Old-Old: 75 to 84
      • Oldest-Old: 85 to 99
      • Centenarians: 100+ years old

    Prenatal Period

    • Physical development: rapid growth, body structures and organs form, brain growth spurt begins, and vulnerability to environmental influence is great
    • Cognitive development: abilities to learn, remember, and respond to sensory stimuli develop
    • Psychosocial development: fetus responds to mother's voice and develops a preference for it

    Infancy and Toddlerhood

    • Physical development: all senses and body systems operate at birth, brain grows in complexity, physical growth and motor skills development are rapid
    • Cognitive development: abilities to learn, remember, use symbols, and solve problems develop
    • Psychosocial development: attachments to parents and others are formed, self-awareness develops, shift from dependence toward autonomy occurs, and interest in other children increases

    Early Childhood

    • Physical development: growth is steady, appearance becomes more slender and proportions more adultlike, appetite diminishes, and sleep problems are common
    • Cognitive development: thinking is somewhat egocentric, but understanding of other people's perspective grows, cognitive immaturity results in some illogical ideas about the world
    • Psychosocial development: not mentioned explicitly, but implied to continue from infancy and toddlerhood

    Generations

    • Silent Generation: 1928-1945
    • Baby Boomers: 1946-1964
    • Generation X: 1965-1980
    • Millennials: 1981-1996

    Developmental Psychology

    • Development refers to the systematic study of processes of change and stability throughout the life span.
    • Life-span perspective emphasizes the study of human development from conception to death, including all physical, cognitive, social, and emotional changes.

    Physical Development

    • Prenatal period: conception to birth, with embryo (2-8 weeks) and fetus (9 weeks to birth) stages.
    • Infancy: birth to 2 years, with neonate (birth to 1 month) and infancy (1 month to 1 year) stages.
    • Early childhood: 2 to 6 years, with toddlerhood (2-3 years) and preschool (3-6 years) stages.
    • Middle childhood: 6 to 11 years, with early school age (6-8 years) and late school age (9-11 years) stages.
    • Adolescence: 12 to 18 years, with early adolescence (12-14 years), middle adolescence (15-17 years), and late adolescence (18-21 years) stages.
    • Young adulthood: 22 to 40 years, with early adulthood (22-25 years) and middle adulthood (26-40 years) stages.
    • Middle age: 40 to 65 years, with early middle age (40-49 years) and late middle age (50-65 years) stages.
    • Late adulthood: 65+ years, with young-old (65-74 years), old-old (75-84 years), and centenarians (85+ years) stages.

    Cognitive Development

    • Sensorimotor period: birth to 2 years, infants learn through senses and motor skills.
    • Preoperational period: 2 to 7 years, children use symbols and language, but are egocentric and unable to think logically.
    • Concrete operational period: 7 to 11 years, children become logical and think concretely, but not abstractly.
    • Formal operational period: 11 years and up, adolescents and adults develop abstract thinking and reasoning.

    • Maturation is the unfolding of a natural sequence of physical and behavioral changes.

    Developing Contexts

    Family

    • A nuclear family consists of two-generational kinship, economic, and household of one or two parents and their biological/adopted/step children.
    • An extended family is a multi-generational kinship of parents, children, and relatives living together in an extended family household.

    Socioeconomic Status (SES) and Neighborhood

    • Socioeconomic status (SES) is a combination of economic and social factors describing an individual or family, including income, education, and occupation.
    • Neighborhood refers to individuals around a person, especially non-relatives.

    Culture and Race/Ethnicity

    • Culture is a society's or group's total way of life, including customs, traditions, beliefs, values, language, and physical products --- all learned behavior, passed on from parents to children.
    • An ethnic group is a group united by ancestry, race, religion, language, and/or national origins, which contribute to a sense of shared identity.

    Developmental Theories

    Psychosexual Development of Sigmund Freud

    • According to Freud, psychosexual development is driven by inner forces, especially biological maturation.
    • Psychosexual development, levels of the mind, and structure of the personality are three famous theories related to development.

    Levels of Consciousness

    • Conscious refers to being fully aware and immediate.
    • Preconscious is the area where unconscious information is easily brought about.
    • Unconscious involves repressed feelings, thoughts, and memories.

    Structure of the Mind

    • Id is guided by the pleasure principle, existed since birth, is illogical, and has no morality.
    • Ego is guided by the reality principle, existed since infancy, and operates the secondary process.
    • Superego is guided by the moral principle, existed since the child was indoctrinated by moral values from the parent, and has no contact with reality since the desire is perfection.

    5 Stages of Functioning

    • The 5 stages of functioning include slaying of the dragon, restitution, second adolescence, extended middle age, and integrity vs. despair.
    • Slaying of the dragon involves defeating aspects of one's upbringing to compensate for them.
    • Restitution involves understanding the limitations of options for one's children and offering new options.
    • Second adolescence bridges the generation gap by offering new solutions to old problems.
    • Extended middle age involves conserving what one has and passing on values, language, and skills to the next generation.
    • Integrity vs. despair involves accepting death with intimacy with others and a sense of purpose in life.

    3 Domains of Development

    • The 3 domains of development include physical and motor development, cognitive development, and psychosocial development.
    • Physical and motor development involves growth of the body and its structures, including changes in size, shape, and motor skills, and development of perceptual capacities.
    • Cognitive development involves changes in an individual's thought processes, including learning, remembering, solving problems, and using language.
    • Psychosocial development involves changes in an individual's emotions, personality, and social relationships.

    Nature vs. Nurture

    • Heredity refers to traits or characteristics that are inborn, determined by one's genetic makeup.
    • Environment refers to all external conditions and experiences that affect an individual's development.

    Developmental Theories

    • Psychoanalytic theories state that development is the result of unconscious forces operating within three parts of the mind: id, ego, and superego.
    • Id is the impulsive, pleasure-seeking part of the mind present at birth.
    • Ego is the rational part of the mind that seeks to balance the id's desires with reality.
    • Superego is the moral part of the mind that reflects societal values and standards of behavior.
    • Learning theories state that people's behavior is shaped by interactions with their environment through rewards and punishments.
    • Classical conditioning involves pairing a neutral stimulus with a meaningful stimulus, so that the neutral stimulus eventually elicits the same response as the meaningful stimulus.
    • Operant conditioning involves reinforcing a behavior when followed by a positive consequence or punishing it when followed by a negative consequence.
    • Social learning theory involves learning through observing the behavior of others and the consequences of that behavior.
    • Cognitive-developmental theories focus on how people's thinking changes as they grow older.
    • Piaget's theory focuses on how children develop more sophisticated ways of thinking as they mature through a series of qualitatively different stages.
    • Vygotsky's theory emphasizes the social context of cognitive development.
    • Humanistic theories focus on the unique potential of each individual and the importance of free will.
    • Maslow's hierarchy of needs states that people are motivated by a hierarchy of needs, starting with basic survival needs and moving up to more complex needs such as belonging, esteem, and self-actualization.
    • Rogers' self theory states that each person is motivated to self-actualize, or become a fully functioning person.

    Cognitive Stages (Jean Piaget)

    • Sensorimotor Stage (birth to 2 years): Infants gradually organize activities in relation to the environment through sensory and motor activity.
    • Preoperational Stage (2 to 7 years): Children develop a representational system, using symbols to represent people, places, and events, with language and imaginative play being important manifestations, but thinking is still not logical.
    • Concrete Operational Stage (7 to 11 years): Children can solve problems logically if focused on the present, but cannot think abstractly.
    • Formal Operations (11 years through adulthood): Individuals can think abstractly, deal with hypothetical situations, and think about possibilities.

    Life Formation

    • Fertilization/Conception: The union of sperm and ovum produces a zygote.
    • Gametes: Sex cells, with women typically having 2 million immature sex cells, which mature every 28 days.
    • Zygote: A one-celled organism resulting from fertilization.
    • Multiple Births:
      • Monozygotic twins: Twins from the division of one zygote, having identical genes, also known as identical twins.

    Mechanisms of Heredity

    • Deoxyribonucleic acid (DNA): The chemical that carries inherited instructions for the development of all cellular forms of life.
    • Chemical units (Bases):
      • Thymine paired with Adenine
      • Guanine paired with Cytosine
    • There are approximately 3 billion pairs per DNA molecule.
    • Genetic Code: The sequence of bases within the DNA molecule that governs the formation of proteins, determining the structure and functions of living cells.
    • Chromosomes: Bundles of genes, with all cells in the body except gametes having 23 pairs, with 23 from the father and 23 from the mother forming the pairs.
    • Sex Determiner:
      • Autosomes: 22 pairs of chromosomes not related to sexual expression.
      • Sex Chromosome: The 23rd chromosome that determines sex, with the ovum carrying an X sex chromosome and the sperm carrying either an X or Y sex chromosome.
      • During fertilization, if X chromosome is paired with another X, then XX (female) is formed, otherwise, if X is paired with Y, then XY (male) is formed.
    • Patterns of Genetic Transmission:
      • Gregor Mendel: The father of genetics who discovered dominant and recessive inheritance.
      • Allele: The expression of a characteristic of a gene.

    • Studies the relative influence of heredity and environment on behavior, aiming to understand individual differences in traits.
    • Heritability: a statistical estimate of heredity's contribution to individual differences in a specific trait within a population, ranging from 0.0 to 1.0.

    Methods of Study

    • Family Studies: examines correlation of traits within families to infer hereditary influence (e.g., obesity in families).
    • Adoption Studies: separates environmental from genetic influence by investigating similarities between adopted children and their biological/adoptive parents.
    • Twin Studies: compares behavioral similarity of identical and fraternal twins.

    Interplay of Genetics and Environment

    • Reaction Range: the potential expression of a hereditary trait, influenced by environmental opportunities and constraints (e.g., body size, height).
    • Canalization: certain behaviors develop along genetically predetermined channels, but can be altered by extreme environmental changes (e.g., early walking, communication skills).
    • Genotype-Environment Interaction: similar environmental conditions affect genetically different individuals differently (e.g., allergic reactions to pollen, antisocial personality development).
    • Genotype-Environment Correlation: genetic and environmental influences align in the same direction.

    3 Ways of Correlation

    • Passive Correlations: environment created by biological parents with the same trait (e.g., music-loving parents create a music-rich environment).
    • Reactive/Evocative Correlations: environment created by parents in response to early signs of dispositions (e.g., enrolling a music-inclined child in music academy).
    • Active Correlation: individuals seek environments compatible with their genotype (e.g., music-inclined teenagers forming a band).

    Behavioral Genetics

    • Studies the relative influence of heredity and environment on behavior, aiming to understand individual differences in traits.
    • Heritability: a statistical estimate of heredity's contribution to individual differences in a specific trait within a population, ranging from 0.0 to 1.0.

    Methods of Study

    • Family Studies: examines correlation of traits within families to infer hereditary influence (e.g., obesity in families).
    • Adoption Studies: separates environmental from genetic influence by investigating similarities between adopted children and their biological/adoptive parents.
    • Twin Studies: compares behavioral similarity of identical and fraternal twins.
