3.  Primary  -  Secondary

4.  Continuous  The behavior is reinforced every time it occurs  This schedule is best used at the beginning of a reinforcement exercise  - why wouldn’t continuous reinforcement work?

5. reinforcing a response only part of the time  results in slower acquisition  greater resistance to extinction

7.  Fixed- set  Variable- changes  Ratio- number  Interval- time

8.  reinforces a response only after a specified time has elapsed  response occurs more frequently as the anticipated time for reward draws near

9.  reinforces a response at unpredictable time intervals  produces slow steady responding  like pop quiz

10.  Fixed Ratio (FR)  reinforces a response only after a specified number of responses  faster you respond the more rewards you get  different ratios  very high rate of responding  like piecework pay

11.  Variable Ratio (VR)  reinforces a response after an unpredictable number of responses  average ratios  like gambling, fishing  very hard to extinguish because of unpredictability
