    1. Biological Level of Analysis: physiology and behavior Outline principles that define the biological level of analysis

    2. Warmup: INTRO TO BIOLOGICAL PERSPECTIVE HANDOUT 2–1 Fact or Falsehood? T F 1. A small amount of brain tissue from a person cannot be distinguished from that of a monkey. T F 2. The human brain produces its own natural opiates that elevate mood and ease pain. T F 3. Electrically stimulating a cat’s brain at a certain point can cause the animal to cower in terror in the presence of a small mouse. T F 4. Both animals and humans seem to have reward centers located in the brain. T F 5. We ordinarily use only 10 percent of our brains. T F 6. Some people can write but are unable to read. T F 7. If a blind person uses one finger to read Braille, the brain area dedicated to that finger expands. T F 8. Adult humans cannot generate new brain cells. T F 9. Some people have had the hemispheres of their brains split with no apparent ill effect. T F 10. Identical twin pairs are necessarily both left-handed or both right-handed.

    3. What does this perspective argue? Behavior is caused by physiology. Humans should be studied as biological systems We should also consider environment and cognition – they interact with our biology . This relationship is bidirectional, i.e. biology can affect cognition and cognition can affect biology.
