Overview of Developmental Psychology

  • Developmental psychology: Focuses on changes and development across the lifespan, including social, cognitive, and emotional changes.

Methods of Studying Development

  • Cross-Sectional Method:

    • Involves studying different age groups at a single time point (e.g., comparing 20, 40, and 60-year-olds).

    • Measures variables like working memory across ages.

    • Limitations: Cannot establish cause and effect; susceptible to cohort effects (differences might not be due to age).

  • Longitudinal Method:

    • Involves measuring the same group of participants across multiple time points.

    • Helps track changes over time and reduces cohort effects.

Nature vs. Nurture

  • Development is a complex interaction between genetic (nature) and environmental (nurture) influences.

  • Example: Some reflexes, like the riding reflex, can be impacted by the environment during early life.

Piaget's Stages of Cognitive Development

  • 1. Sensorimotor Stage (Birth to 2 years):

    • Infants learn to coordinate sensory experiences with motor actions (e.g., reaching for objects).

    • Object permanence develops (understanding that objects exist even when out of sight).

  • 2. Preoperational Stage (2 to 7 years):

    • More logical thought begins to emerge but still has limitations (e.g., egocentrism and centration).

    • Example: Children may not understand that the amount of liquid is the same when poured into different-shaped containers.

  • 3. Concrete Operational Stage (7 to 11 years):

    • Logical reasoning improves; children can perform operations mentally.

    • Children learn conservation; they understand that changing the shape of an object does not change its amount.

    • Ability to mentally reverse actions is emphasized.

  • 4. Formal Operational Stage (11 to 15 years):

    • Abstract thinking and problem-solving capabilities are developed.

    • Adolescents can think about hypothetical situations and future possibilities.

Critiques of Piaget's Theory

  • Development may not be strictly stage-like; it's often continuous.

  • Underestimates the capabilities of younger children (e.g., object permanence may develop earlier than Piaget asserted).

  • Overestimates the cognitive abilities of adolescents and adults.

Vygotsky's Sociocultural Cognitive Theory

  • Cognitive development occurs within a social and cultural context, emphasizing the role of social interactions.

  • Zone of Proximal Development (ZPD): Distinguishes between what a child can do independently versus with assistance from more knowledgeable individuals.

  • Scaffolding: Support provided by caregivers to help children learn, which is gradually withdrawn as they become more independent.

Socioemotional Development

  • Temperament:

    • Refers to basic emotional style evident in infancy, largely influenced by genetics.

    • Types of temperament identified by Thomas and chess:

      • Easy: Relaxed, adaptable, positive mood.

      • Difficult: Fussy, easily frustrated.

      • Slow to Warm Up: Cautious, withdraws but gradually adjusts.

  • Attachment:

    • Emotional bond between infant and caregiver, critical for social and emotional development.

    • Harlow's Experiment: Demonstrated that contact comfort is more important than nourishment for forming attachments in monkeys.

    • Ainsworth's Strange Situation: Classified attachment styles based on infant behavior when separated from and reunited with their caregiver:

      • Secure Attachment: Using caregiver as a secure base.

      • Insecure Attachment: Includes avoidant (indifferent) and anxious (distressed but not comforted) types.

Erikson's Stages of Socioemotional Development

  • Proposes eight stages that explore challenges across the lifespan:

    1. Trust vs. Mistrust (Birth to 1.5 years) - Developing trust when caregivers meet needs.

    2. Autonomy vs. Shame and Doubt (1.5 to 3 years) - Developing independence and control.

    3. Initiative vs. Guilt (3 to 5 years) - Taking initiative in activities and decision making.

    4. Industry vs. Inferiority (6 years to puberty) - Developing competence in academic and social skills.

    5. Identity vs. Identity Confusion (Ages 10-20) - Exploring and establishing personal identity.

    6. Intimacy vs. Isolation (Young adulthood) - Forming meaningful relationships.

    7. Generativity vs. Stagnation (Middle adulthood) - Contributing to society and the welfare of future generations.

    8. Integrity vs. Despair (Late adulthood) - Reflecting on life and achieving a sense of fulfillment or regret.

Cognitive Development in Adulthood

  • Cognitive Performance: Peaks in early adulthood and generally declines with age, particularly in processing speed.

  • Accumulated wisdom and knowledge may increase with age, despite slower processing speeds.

  • Factors such as exercise, engagement in activities, and social connections can help mitigate cognitive decline in older adults.
