    Study Notes

    Biological Influences on Development

    • Genes: organized segments of DNA that influence behavior and physical attributes
    • Chromosomes: strands of genes that undergo mitosis and meiosis
    • Alleles: variations in genes that can affect behavior and attributes
    • Behavioral Genetics:
      • Studies the relationship between genes and behavior
      • Uses family, twin, and adoption studies to identify genetic and environmental influences
    • Molecular Genetics:
      • Links alleles with attributes and behaviors
      • Uses linkage and association studies to identify genes implicated in disorders

    Brain Development

    • The brain consists of 100 billion neurons that communicate using chemical messengers (neurotransmitters)
    • Brain development:
      • Organized from the bottom up (brain stem, cerebellum, basal ganglia, limbic system)
      • Higher-order regions may not mature until adulthood
      • Experience can affect the brain through gene-driven, experience-expectant, and experience-dependent processes

    Diathesis-Stress Model and Epigenetics

    • Diathesis-Stress Model: proposes that children must have a genetic risk and environmental stressor to develop a disorder
    • Gene-Environment Correlation Model: assumes that genes and environment are related
    • Epigenetics: alters gene expression without changing the DNA sequence, influenced by experience

    Psychological Influences on Development

    • Learning Theories:
      • Classical Conditioning: associates unconditioned stimulus with conditioned stimulus
      • Operant Conditioning: associates behavior with consequences (reinforcement, punishment)
      • Social Learning: learns from observing others
    • Cognitive Development:
      • Four stages: sensorimotor, preoperational, concrete operations, and formal operations
    • Social Cognition:
      • Capacity to think about social situations
      • Schemas: central to social cognition, underlying social disorders
    • Emotional Development:
      • Refinement of child's emotional experience
      • Emotion regulation: effortful and reactive processes
      • Causes of internalizing and externalizing disorders

    Social-Cultural Influences on Development

    • Parental Influences:
      • Temperament: actions and emotions in response to environmental stimuli
      • Goodness-of-Fit: relation between temperament and demands
      • Attachment: emotional bond between caregiver and child
    • Peer Influences:
      • Importance of friendship to social-emotional development
      • Interpersonal Theory: stages of interpersonal development, peer acceptance and rejection
    • Other Social-Cultural Factors:
      • Proximal and Distal Risk: proximal risk factors, distal risk factors, and their influence on development
