Active avoidance requires performing a specific behavior in order to escape or avoid the aversive stimulus. It is a conditioning paradigm in which the animal learns to control the application of an unconditioned stimulus (US), in this case, a foot shock, by appropriately reacting to a conditioned stimulus (CS) preceding the US, such as a light cue. The first stage of avoidance learning is usually to escape from the US. With continued training, anticipatory reactions appear which enable the animal to avoid the US altogether. In the active avoidance test, the rodent is placed into a shuttle box and is trained to move to the opposite side of the box in response to a cue that signals an incoming foot shock. Movement to the opposite side of the chamber in response to the presentation of the shock-predictive cue alone is regarded as active avoidance, whereas movement to the opposite side of the chamber only after receiving foot shock is regarded as an escape response.
