  • 1. CHARACTERISTICS OF STUDENTS WITH MILD/MODERATE INTERVENTION NEEDS SPED 4/53050 INSTRUCTOR: BRIAN FRIEDT Week four: Causal factors
  • 2. On complexity
    • Causal factors happen across several variables:
      • Biological
        • Genetic, psychological, brain development, disease...
      • Environmental
        • Nutrition, toxin exposure, community factors, social/cultural
    • Risk factors/resiliency factors
    • It is often difficult to isolate a “cause”
      • AAIDD reports that 40-50 percent of cases of cognitive disabilities are idiomatic
    • To a degree, causes aren’t critical in educational settings
  • 3. Risk factors
    • Time:
      • Prenatal
      • Perinatal
      • Postnatal
    • Type:
      • Genetic
      • Environmental
  • 4. Biological risk factors
    • Brain development and function
      • EBD
        • Neurotransmitters
        • Chemical imbalance
      • SLD
        • Definitionally suggested: CNSD
        • Prenatal brain asymmetry
        • Blood flow
        • Structural differences
      • CD
        • There’s a lot going on in the brain
        • As before, there are some things we can clearly identify and many that we cannot
  • 5. Biological risk factors
    • Genes/heredity
      • Hereditary information points well to the idea of interplay amongst many factors: there is no gene for SLD
      • EBD
        • Genetic predisposition
        • Some genetic component
      • SLD
        • Genetic predisposition
        • Remember: risk factor, not certainty factor
      • CD
        • Complex interaction of genetic factors and environmental factors
        • Down Syndrome, PKU, Trisomy 18...
  • 6. Biological risk factors
    • Temperament
      • Temperament is fairly stable from birth
      • Clearly biological due to that persistence
      • EBD
        • Irritable, withdrawn, intense reactions
      • SLD
        • Little ability to sustain attention, distractible, lack of persistence
      • CD
        • Less adaptable, inquisitive, persistent, and responsive
  • 7. Biological risk factors
    • Good teaching!
  • 8. Environmental risk factors
    • Prenatal:
      • Age/health of parents
      • Maternal malnutrition/exposure to teratogens/infection
      • Drug/alcohol abuse
    • Perinatal:
      • Low birth weight
      • Anoxia
    • Postnatal:
      • Malnutrition
      • Teratogens
  • 9. Environmental risk factors
    • Family
      • Experience
      • Nurturing/Stimulating/Consistent
      • Trauma
    • Community
      • Poverty
    • School
      • Gap
      • Attendance
  • 10. Summing up
    • Good teaching!
