Extinction
Passage of time has very little effect on strength of CR
Use extinction to remove or reduce the CR
Present the CS without the US
Remember predictability!

Spontaneous Recovery
The response returns
Time between extinction trials will affect this
The larger the gap the larger the SR
On each trial you will see less and less SR

Rapid Reacquisition
Acquisition – extinction – reacquisition
With each extinction/reacquisition the organism learns the CR quicker
