3. Positive Loop Closes! Positive Loop Closes! RR environment random noise i i e Jan needs to be in bed at 7pm Jack puts Jan in bed Jan wants to stay up i i comparator G-i=e Jan throws tantrum Jack compares goal and outcome... error G= bed at 7pm i= Jans tantrum e= Jan not in bed Jan isnt in bed! Jack has to do something to get to the goal Jack decides to close door Jan is scared when the door is closed Jack threatens to close the door Jan wants door to stay open Jan loses it! Jack again compares goal and outcome... more error! Jan isnt in bed and now Is screaming like a banshee Jack still has to do something to end the tantrum Jack decides to hold Jan and sing Jan likes to be held and sung to by daddy Jack holds Jan and begins singing Jan is comforted by the singing Jan falls asleep Jack compares goal and outcome... goal is met Jan is in bed SYSTEM G= stop tantrum i= Jan asleep e= Jan not crying AND in bed
