2. Excitatory Conditioning
 The CS elicits activity
related to the US
 Without the US
 Show fear in
presence of furry
creatures
 Your system is
‘excited’
 A response is
added.

 A connection added.

3. Delay Conditioning
ISI < 1 minute
ISI typically 5-10 minutes
CEDP 324 Ryan Sain, Ph.D. 3 3/29/2012

4. Trace Conditioning
•Sometimes called a ‘trace interval’
•Typically the ISI or TI is less than 1 minute

5. Simultaneous
Seems to make sense – but it is not very effective
CEDP 324 Ryan Sain, Ph.D. 5 3/29/2012

6. How to measure CRs?
 Magnitude
 Strength, quantity
 Probability
 Likelihood that a CS  CR
 Latency
 CS … or ……… CR

7. Inhibitory Conditioning
 Rather the devil you
know, than the devil
you don’t!
 Predictability is
powerful
 Signaling the absence
of a US.
 Library  no loud
noises
 Shelter  no bitter
cold wind
CEDP 324 Ryan Sain, Ph.D. 7 3/29/2012

8. The procedure
 Present the CS as
normal.
 The CS+ (US)  CR
 Red light (danger) 
stopping
 Present a second
stimulus concurrently
 CS+, CS-  ______
 The CS- signals
that no US will
happen
 Red light, cop
signaling 
driving
CEDP 324 Ryan Sain, Ph.D. 8 3/29/2012

9. Another procedure
 CS- is negatively correlated with a US.
 Or predicts a long absence of the US
CEDP 324 Ryan Sain, Ph.D. 9 3/29/2012

10. Prevalence
 Fear
 Causal events
 Food aversions
 Emotions
 Fertility
