  1. Biological Level of Analysis (2)

  2. Review What are nerve cells called? What are the main parts of a nerve cell (neuron) IN ORDER? TRUE OR FALSE: the axon terminals of one neuron touch the dendrites of the next neuron when transmitting a message/signal What are the 4 lobes of the brain?

  3. Review How many hemispheres are there in the brain? What is the “little brain” really called? What is the bundle of fibers called that connects the 2 hemispheres?

  4. 1. What does it mean for something to be “innate”? • 2. Does evolution play a role in behavior?

  5. Today’s Objective… • Learning Intention: Outline the 3 principles of the Biological Level of Analysis (LoA) • Success Criteria: Students will demonstrate mastery of 3 principles and supporting research on upcoming evidence

  6. FIRST… • WHAT IS THE NATURE VS. NURTURE DEBATE? • Nature: human behavior is the result of biological factors • Nurture: human behavior is the result of environmental factors

  7. 3 Principles of the Biological LoA • 1. ? • 2. ? • 3. ? • ….Look them up in your book! You tell ME! • (pages 38 & 39)

  8. 3 Principles of the Biological LoA • 1. Behavior can be innate because it is genetically based • 2. Animal research can provide insight into human behavior. • 3. There are biological correlates of behavior

  9. 3 Principles of the Biological LoA • PRINCIPLE #1 • Behavior can be innate because it is genetically based

  10. Principle #1: Behavior can be innate because it is genetically based • TWIN STUDIES • Why study twins? • What are Monozygotic twins? • Dizygotic twins? • Diathesis-Stress Model • Genetic predisposition (diathesis) to develop a disorder that MAY OR MAY NOT be brought out by the environment (stress)

  11. Principle #1: Behavior can be innate because it is genetically based • Twins separated at birth http://www.youtube.com/watch?v=0yTCShemS_0&feature=related

  12. 3 Principles of the Biological LoA • PRINCIPLE #2 • Animal research can provide insight into human behavior.

  13. Principle #2: Animal research can provide insight into human behavior. • Why study animals? • What do we use them to study? • What ethical problems can we face by studying animals? • For more info, visit… http://www.bbc.co.uk/ethics/animals/using/experiments_1.shtml

  14. Principle #2: Animal research can provide insight into human behavior. • Animal experiments are widely used to develop new medicines and to test the safety of other products • Many experiments cause pain to the animals or reduce the quality of life in other ways • What is ablation? • What is lesioning? • What do these two methods tell us?

  15. Principle #2: Animal research can provide insight into human behavior. PRO-ANIMAL TESTING ANTI-ANIMAL TESTING Experimenting on animals is always unacceptable because: It causes suffering to animals The benefits to human beings are not proven Any benefits to human beings that animal testing does not provide could be produced in other ways • Experimenting on animals is acceptable if (and only if): • Suffering is minimized in all experiments • Human benefits are gained which could not be obtained by using other methods

  16. 3 Principles of the Biological LoA • PRINCIPLE #3 • There are biological correlates of behavior

  17. Principle #3: There are biological correlates of behavior • Implies that it should be possible to find a link between a specific biological factor (ex: hormone or neurotransmitter) and a specific behavior • THIS IS THE AIM OF RESEARCHERS IN THIS LOA • EX: Acetylcholine • Too much: Parkinson’s • Not enough: Alzheimer’s

  18. Principle #3 Examples of neurotransmitters & hormones that are in charge of really important things: Acetylcholine Dopamine Serotonin Growth Hormone Leptin Ghrelin • Is lack of sleep making me fat? http://www.youtube.com/watch?v=uxezLHDECUo
