The child’s crying and tantrum was _____ by the father’s buying of the candy? The father’s buying the candy was ______ by the child’s stopping the crying and tantrum?

  5. Important Concepts • Immediate reinforcement is more effective than delayed reinforcement. • Shaping: reinforcing successive approximations toward a final response.

  6. Also in Operant Conditioning: • Extinction • Spontaneous Recovery • Generalization • Discrimination

  7. Partial Reinforcement • Fixed-Ratio Schedule • Variable-Ratio Schedule • Fixed-Interval Schedule • Variable-Ratio Schedule
