Fig 1.
Mean percent activity on conditioning days as a function of conditioning, and haloperidol dose.
Percent activity was collapsed across each 60 min session. The animals had received either 0.5 mg/kg or 2.0 mg/kg of haloperidol before (P: Paired) or after (U: Unpaired) being introduced in the context-CS for 60 min.
Fig 2.
Mean percent activity on the drug-free test day as a function of conditioning, and haloperidol dose.
(A) Percent activity is represented collapsed across 10-min periods, and (B) across the complete 60-min session. The animals had received either 0.5 mg/kg or 2.0 mg/kg of haloperidol during the four days of the conditioning stage before (P: Paired) or after (U: Unpaired) been exposed for 60 min to the context-CS. Test session was drug-free.

Mean percent activity on conditioning days as a function of conditioning.
Percent activity was collapsed across each 60 min session. The animals had received 0.5 mg/kg of haloperidol before (P: Paired) or after (U: Unpaired) being introduced in the context-CS for 60 min.
Fig 4.
Mean percent activity on the drug-free test day as a function of conditioning, and haloperidol dose.
(A) Percent activity is represented collapsed across 10-min periods, and (B) across the complete 60-min session. The animals had received 0.5 mg/kg of haloperidol during the four days of the conditioning stage before (condition P: Paired) or after (condition U: Unpaired) been exposed for 60 min to the context-CS. Test session was drug-free.
