Presentation Transcript

  1. Adapting- Learned Intelligence WFSC 422 Ethology Presentation 2.1 Dr. Jane M. Packard, WFSC TAMU j-packard@tamu.edu

  2. Changed behavior matches changed environment (FP) VIDEO

  3. Concept Map- Adapting

  4. What is intelligence? • Learning • Problem-solving • Communication • Awareness

  5. Learning: Step 1- “bridging” associates clicker & reward VIDEO

  6. Learning: Step 2 “targetting” associates stimulus & response video

  7. “bridging” click stimulus give food reward repeat until animal looks for food at the click Click stimulus means food reward “targetting” present target stimulus click when the animal is close to target Give food reward repeat until animal touches target Target stimulus means food reward CAUSE: Learning (external)

  8. CAUSE: learning (internal) VIDEO VIDEO

  9. Learning: adapt to short-term change

  10. Evolution of the Brain VIDEO

  11. “Reptile Brain” • Limbic system- surrounded by the cortex • ancestral trait • primitive in fish • persisted in the rest of the vertebrates • seat of the emotions • activates motivational systems • associations of “good” and “bad” • similar- humans & other vertebrates • neural basis for learning via reward

  12. Behavior complexity low- reptile high- predator highest- mammals that live long lives Relative size of cortex small- fish aquatic environment medium- reptile evolved on land emotions largest- mammals complexities of surviving the ice ages UE: Comparative brain anatomy

  13. What is intelligence? • Learning • Problem-solving • Communication • Awareness

  14. Example: problem-solving

  15. CDEF: Problem-solving

  16. What is intelligence? • Learning • Problem-solving • Communication • Awareness

  17. Example: Communication

  18. CDEF: Communication

  19. What is intelligence? • Learning • Problem-solving • Communication • Awareness

  20. C: ape touches own forehead when it sees a painted dot in the mirror F: those that were aware of their own body as distinct were better able to control effects of their actions on others D: depends on previous experiences with mirrors E: divergence- monkeys do not pass the mirror test, chimps, orangs, gorillas, humans do CDEF: Awareness

  21. Learning: response changes in lifetime; ability over geologic time VIDEO

  22. Fixed Instinct: no change

  23. Ultimate UE & UF More ability to learn in larger cortex Natural selection favored genotypes with more cortex in environments that changed more Proximate PC & PD Learning- (eg. kids) problem-solving (e.g. raven) Communication (e.g. parrot Alex) Awareness (e.g. chimp mirror test) Summary

  24. Action Items • Do answers for Q2.1, Q2.2 • Search keywords “intelligence” "awareness“ • Web of Science • Google Scholar • Post examples & sources on WebCT Discussion for Unit 2
