  11. Negative Reinforcement • Behaviour is reinforced by the avoidance of a negative situation • Here pressing the lever will stop the shocks http://www3.niu.edu/acad/psych/Millis/History/2003/skinbox3.gif

  15. Extinction • Removing something to reduce a behaviour • This is perhaps the worst method of learning • What do you do when a baby annoys you with a rattle? Extinction: You take the rattle
