Reinstatement of cocaine CPP in absence or presence of social interaction during extinction.

Compartment (s) ± SEM	Drug-paired compartment	Neutral compartment	Saline-paired or saline + social interaction-paired compartment
Cocaine CPP after saline extinction (n = 13)	393 ± 17*	299 ± 12	208 ± 17
Cocaine CPP after counterconditioning to social interaction (n = 13)	242 ± 18*	325 ± 17	333 ± 25

Shown is time spent in the cocaine-, neutral, or saline- associated compartment. Shown are group means ± SEM.

^*P < 0.05 compared to the time spent in the saline chamber or social interaction chamber.
