  1. 1. Ivan Pavlov Roxsana Guzman Landers - 4 May 17, 2009
  2. 2. Background Information <ul><li>Born: September 14, 1849 </li></ul><ul><li>Birthplace: Ryazan, Russia </li></ul><ul><li>Education: Attended Ryazan Ecclesiastical Seminary for several years, dropped out and enrolled at the University of St. Petersburg. Earned his doctorate (equivalent to a Bachelor's Degree) in 1879 </li></ul><ul><li>Death: February 27, 1936 </li></ul>
  3. 3. The Beginning.... <ul><li>Pavlov was planning to study saliva (which he received from dogs), collect normal data and see the reaction it had on certain foods. </li></ul><ul><li>While attempting to collect saliva from dogs he noticed that the dogs tended to pro </li></ul><ul><li>He called this phenomenon “psychic secretion&quot; </li></ul><ul><li>His attention then turned from saliva to behaviorism </li></ul>
  4. 4. His Experiments <ul><li>Pavlov determined to discover the roots of this phenomenon. </li></ul><ul><li>He did series of experiments where he rang a bell just before he served the dog food </li></ul><ul><li>He called these reflex produced by the stimulus (in this case the bell and food served afterward) “conditional reflexes” </li></ul>
  5. 6. Conditional Reflexes <ul><li>Once satisfied with his experiments, Pavlov establish the basic rules of “conditional reflexes” </li></ul><ul><li>He stated that conditional reflexes can only occur when responses become automatic after several experiences where the condition (Pavlov's case was the bell) occurs </li></ul><ul><li>Even after Pavlov's discovery his experiments and findings wouldn't be published in English until 1927 </li></ul>
  6. 8. The Experiment of his death...? <ul><li>On the day of his death, Pavlov asked one of his students to stay by his bed side and record the conditions of his death </li></ul><ul><li>It's believe Pavlov wanted to create evidence of particular experiences in one's last moments in life </li></ul><ul><li>It takes a great scientist to want to increase their knowledge on their death bed. </li></ul>
  7. 9. Interesting Facts / Conclusion It's almost incredible to believe he was son of a village priest and who's mother was daughter of a priest. He seemed destined to end up preaching just as his father, but out came this great man who studied extensively the digestive system of both humans and animals and deserve the recognition he's received. Through Pavlov's extensive research and experiments he managed to win himself the 1904 Nobel Prize in Physiology and Medicine for successfully extracting digestive organs out of animals. A great man was he who spoke these words “Don't become a mere recorder of facts, but try to penetrate the mystery of their origin.”
