Extinction

• Procedure in which an event that followed a
  behavior is stopped
• Rate of behavior decreases
• Unintentional extinction
• Extinction Burst
• Watch Out! Theres a temporary increase in
  responding as soon as extinction begins

3
Other Extinction Phenomenon

• Spontaneous Recovery
• Reappearance of a beh previously extinguished
• Easier to extinguish
• Relearning Savings
• Easier to condition a previously extinguished
  response

4
Thus Far

• You have learned 2 tactics
• You can increase desired beh thru rft
• You can decrease undesired beh thru ext
• There will be times in a program that you want to
  both increase certain beh and decrease others

5
Differential Rft

• Procedure where one behavior is followed by a
  reinforcer and another beh is not (extinguished)

6
How can we condition or train a beh?

• Waitand the reinforce
• Shaping via differential rft of successive
  approximations
• Reinforce desired beh
• Withhold rft for other beh
• Shift rft criteria

7
Important Factors in Beh Mod

• Consistency
• Contiguity
• Immediacy of reward impo
• Delays of rein can impede conditioning and
  strengthen undesired behaviors
• Contigency
• Size of Reinforcer
• Satiation
• Ratio Strain
• Schedule of Rft
