    Study Notes

    Developmental Psychology

    • Focuses on how biological, physical, cognitive, emotional, and social abilities develop throughout childhood.
    • Key debates include stability vs. change, continuity vs. discontinuity, nature vs. nurture, and critical vs. sensitive periods.
    • Studying development helps understand adult minds, clinical conditions, and childhood abilities.

    Infant Development

    • Human development commences in utero.
    • Gestation period is roughly 38-40 weeks.
    • Infant brains are structurally similar to adult brains but smaller at birth, reaching 50% of adult size by 6 months.

    Infant Development - Before/After Birth

    • At birth, neurons are not fully myelinated or connected.
    • Myelination and synaptogenesis (synapse formation) continue until around age two.
    • Unused synapses are trimmed throughout development after age 2.
    • Neural plasticity decreases with age (Huttenlocher, 2002).
    • Damage can occur before birth.

    Teratogens

    • Substances causing atypical development if exposed in utero.
    • Harmful effects on development during pregnancy.
    • Examples include:
      • Perera et al (2002): Air pollution links to genetic mutations.
      • Latini et al (2003): PVC exposure shortens pregnancy, leading to early delivery.
    • Fetal alcohol spectrum disorder (FASD) presents physical, mental, and behavioral impairments from in utero alcohol exposure.
    • FASD impairments:
      • Infancy: Slower reaction times.
      • Preschoolers: Difficulty paying attention, hyperactivity.
      • Childhood: Learning problems, memory deficits.
      • Adulthood: Impaired problem-solving, substance dependence.

    Summary 1

    • Developmental psychology illustrates the emergence, development, and maturation of adult abilities across the lifespan.
    • Brains at birth resemble adult brains but are smaller, undergoing development through myelination and synapses.
    • Exposure to teratogens can cause significant clinical problems in development.

    History of Studying Development

    • Industrial Revolution spurred need for an educated workforce, focusing research on cognitive development.
    • Emotional and social development, as well as adult development, later became focused areas.
    • Key figures include John B. Watson, Charles Darwin, Wilhelm Preyer, with substantial empirical research emerging by the 1880s.
    • 20th-century figures like Piaget, Vygotsky, and Bowlby significantly shaped the field.

    Jean Piaget (1896-1980)

    • Swiss child psychologist creating a cognitive development stage theory through observing own children.
    • Other stage theories include Freud's psychodynamic theory and Erikson's psychosocial theory.
    • Piaget proposed stages from 0-2 (sensorimotor), 2-7 (preoperational), 7-12 (concrete operational), and 12+ (formal operational) years.

    Sensorimotor Stage (0-2 years)

    • Infants can sense and move, but initial cognition is limited.
    • Object permanence (understanding object existence despite lack of perception) is a crucial concept emerging later.
    • A-not-B error demonstrates persistence on incorrect search location due to limited object permanence. Preservation is a similar effect.
    • Mental imagery and symbol understanding emerge by the end of this stage.

    Preoperational Stage (2-7 years)

    • Egocentrism, inability to see from another's perspective, characterizes this stage.
    • Three Mountain task illustrates this egocentrism by showing children's difficulty understanding differing perspectives.
    • Lack of "operations" (logical mental rules) makes children biased by appearances and incapable of conservation.
    • Conservation involves understanding that appearance change doesn't change quantity, volume, mass, or perspective

    Concrete Operational Stage (7-12 years)

    • Children can perform operations but only on concrete (tangible) problems.
    • Systematic reasoning and scientific thought are not developed.

    Formal Operational Stage (12+ years)

    • Abstract thought, hypothetical scenarios, and systematic reasoning emerge.
    • Formal operational thinkers can imagine scientific experiments.

    Piaget's Constructivism

    • Children actively construct their understanding of the world, not passively absorbing information.

    Lev Vygotsky (1896-1934)

    • Social constructivist emphasizing the role of social interaction in knowledge construction.
    • Zone of Proximal Development (ZPD): difference between independent and assisted capabilities.
    • Social referencing—using others' emotional responses to guide actions is vital to learning.

    Theory of Mind

    • Ability to understand mental states of self and others.
    • Development of ToM is demonstrated through false-belief tasks.

    False-Belief Tasks

    • 2-3-year-olds typically fail to understand that others might possess false beliefs—differing from their own.
    • 4-year-olds typically succeed.

    Executive Functions

    • Cognitive abilities for voluntary behavior control.
    • Three main components:
      • Inhibition: Self-control, resisting distraction, stopping responses.
      • Working Memory: Holding information in mind, mental arithmetic.
      • Shifting: Mental flexibility, adapting to new situations.
    • Executive functions are crucial for planning, completing tasks/goals effectively.

    ASD (Autism Spectrum Disorder)

    • Characterized by social skill impairments, communication issues, and repetitive behaviors.
    • Show impairments in theory of mind, executive functions, and imitation skills.
    • Mirror neurons (brain cells active during action observation and execution) are theorized to be involved.
    • Eye tracking studies show some similar expectations in ASD, but difficulties using gaze for intention inference.

    Key Developmental Concepts

    • Teratogens, Piaget's stages, object permanence, perseveration (preservation), egocentrism, conservation, constructivism, zone of proximal development (ZPD), social referencing, Theory of Mind, executive functions, mirror neurons.
