The CPP paradigm provides information on the rewarding or aversive effects of visible and tactile contextual cues associated with drugs. 

This technique has acquired great popularity in research studies involving addiction, being much easier, if compared to drug self-administration procedures. 

First, the animal is conditioned to identify one of the two compartments with the drug experience. Then the time spent in each compartments is measured; preference or
aversion to the drug-paired compartment, hence rewarding/aversive properties of drugs, can be easily deducted.

The CPP test only requires the animal to carry out a simple operation (i.e. move from one compartment to the other) to approach or avoid the drug-paired compartment; the animal is expected to spend more time in the drug-paired compartment, if the drug experience produced a positive effect.
