1. Some Other Conditioning Procedures of Interest
Conditioned Inhibition
Conditioned Facilitation
Second-Order Conditioning
Sensory Preconditioning
Inflation
Deflation

2. Conditioned Inhibition
Definition: A CS signals the absence of an otherwise expected US
Standard Method: Conditioned Inhibition Procedure
CSA
CSA
+CSB

3. Conditioned Inhibition
Notation: A+, AB- A
CS can opener
(excites)
USfood
CS rattle
(inhibits) B

4. Measurement Problem True Inhibition Lack of Excitation
CR actively inhibited = no CR
Lack of Excitation
Lack of excitation = no CR

5. Retardation and Summation Tests
Common Treatment Phase
The Experimental Group receives inhibitory training with CSB
The Control Group receives no training with CSB

6. Retardation Test Group Treatment Test Result Inhibition A+, AB- B+ cr
Control A+, AC- B+ CR

7. Conditioned Inhibition
Why Does the Experimental Group Learn More Slowly?
The Control Group starts at 0.
Excitation +
Going from Trial 1 to Trial 5, the level of excitation increases.
Tendency to Salivate to CSB -
Inhibition

8. Conditioned Inhibition
Why Does the Experimental Group Learn More Slowly?
The Experimental Group starts below 0.
Excitation +
It takes extra trials to bring them up to 0, then more trials to raise the level of excitation.
Tendency to Salivate to CSB -
Inhibition

9. Summation Test Group Treatment Excitor Test Result
Inhibition A+, AB T+ TB- cr
Control A+, AC T+ TB- CR
Logic:
Inhibition: T + B = = 0
Control: T + B = = 1

10. Conditioned Facilitation
Definition: CSA signals the US only in the presence of CSB B
US) (A
Notation: A-, BA+

11. Nature of Conditioning
Question: Does the CS evoke an “expectation” of the US (S-S) or does the CS directly elicit the CR (S-R) ? CS US
S-R Theory CS US UR
S-S Theory CR

12. Second-Order Conditioning
Stage Stage Test
A->US B->A B->CR
Very Few Trials

13. Second-Order Conditioning
The “sad” story of Billy and the Bulldog
First-Order Second-Order
Dog->Bite Elevator->Dog

14. S-S Account Problem: Underlying Fear of Dog Dog->Bite
Elevator->Dog
So…Elevator->Dog->Bite
S-S Therapy: Extinguish Dog Fear

15. S-R Account Problem: Elevator Evokes Fear Dog->Bite
Elevator->Dog
Fear
Fear
So…Elevator-Fear
S-R Therapy: Extinguish Elevator Fear

16. Other Procedures (S-S Only)
Sensory Preconditioning
Inflation
Deflation

17. Sensory Preconditioning
Treatment SPC Result
B->A A->US B->CR
Very Few Trials
S-R Theory
B->no CR
S-S Theory
B->A->US

18. Inflation Treatment Inflate Result A->us US A->CR S-R Theory
A->Same cr
S-S Theory
A-> Bigger CR
