Hemispheric Lateralization & Intelligence and Cognitive Function

HW 3 Covering 1) Hemispheric lateralization (lecture/PowerPoint) and part of Ch. 9),  2) Ch. 13 – Intelligence and Cognitive Functioning.


  1. Epilepsy most commonly involves an abnormality of neurons in the cerebral cortex. Abnormal firing generally starts within this small group of neurons. Why is it that grand mal seizures involve the entire cerebral cortex?
  2. What is a “split-brain” patient? Why is the surgery performed, and, briefly, what are two differences in behavior that are not seen in non-split brain individuals.
  3. Name two anatomical asymmetries that exist in human cerebral cortex. Relate them to the behavior that might be effected.
  4. Define language and indicate the primary sensory areas involved.
  5. A person has had a stroke. The have an inability to produce speech, but, they understand spoken language. Where might the site of the stroke have been?
  6. What is an “IQ”? How is it computed? If someone has an “IQ” of 100 what does this mean in terms of knowledge?
  7. There are two general thoughts/theories about the “structure of intelligence”. Explain/define what they are. Is there an alternative to these two seemingly different ideas about the structure of intelligence?
  8. IQ is a measure of “intelligence. What are several other factors that might go into differentiating levels of intelligence? These are physiological measures.
  9. What is autism? Discuss possible causes of autism. Include a brief discussion of why the “immunization” idea is NOT a reasonable hypothesis.
  10. What is ADHD and what might be some of the causes for it?
  11. For both autism and ADHD discuss some of the findings about brain abnormalities.
