Anticonflict actions of ocinaplon (Upper) and diazepam (Lower) in primates. Punished and nonpunished responding in adult, male squirrel monkeys was performed as described (24). Drugs were administered orally 60 min before a test session. A profound sedation was noted in animals administered 4mg/kg diazepam. Although a significant reduction in nonpunished responding was observed with ocinaplon at 128 mg/kg, overt signs of sedation were not noted. Filled bars, punished (conflict) responding; open bars, unpunished responding; ^*, P < 0.05 paired t test.
