Intellect & Neuropsychology

Neuropsychological Domain of Intellect

  • Neuropsychologists describe brain function through neuropsychological domains.
  • Intellect is the ability to solve problems, representing academic ability or potential, distinct from academic performance.

Causes of Differences in Intellect

  • Genetics: Correlation between parent and child IQ; genetic disorders (e.g., Down syndrome, Fragile X syndrome).
  • Medical Considerations: Prenatal exposure to drugs, alcohol, toxins, or malnutrition; birth injuries (e.g., lack of oxygen).
  • Post-Birth Factors: Illnesses (e.g., meningitis), environmental toxins, head trauma, poverty, cultural deprivation, under-stimulation.

Types of Intellectual Differences

  • Gifted students.
  • Students with developmental disorders, intellectual disabilities, or multiple disabilities.
  • Individuals who have experienced traumatic brain injury.

Resources

  • Videos in module four address intellectual differences from various perspectives.
  • Narratives from individuals with intellectual disabilities and gifted students are included.

IQ Tests

  • IQ tests can be important in identifying intellectual differences but have a problematic history.
  • Alfred Binet and Theodore Simon created the basis for IQ tests in 1905 to identify children needing individualized attention.
  • IQ = (Mental Age / Chronological Age) * 100
  • Early misuse led to dangerous racist policies and eugenics.
  • Flynn effect: IQ scores have increased over generations due to environmental factors (education, healthcare, nutrition).
  • IQ tests should not be used to categorize individuals based on a single numerical score.

Interventions

  • Chaining:
    • Total Task Chaining
    • Forward Chaining
    • Backward Chaining
  • Prompt Types:
    • Prompt fading
    • Least to most prompting
    • Most to least prompting
    • Graduated guidance for fine motor tasks
  • Least Restrictive Environment (LRE):
    • Moving from least to most restrictive settings.
    • Prioritizing general education settings.
  • Repetition and Modeling: Show, explain, practice, rehearse, reinforce, and correct.

Interventions for Gifted Students

  • Enrichment: Presenting curricular content with more depth, breadth, complexity, or abstractness than the general curriculum.
  • Acceleration: Presenting curricular content earlier or at a faster pace.
    • Content acceleration.
    • Grade skipping.
    • Advanced Placement programs.
    • Early graduation or college entrance.
  • Curriculum Compacting:
    • Instructional technique adjusting curriculum for students. Involves:
    • Defining learning outcomes.
    • Determining mastered outcomes.
    • Providing replacement strategies for already mastered material.
