Premature responses from the initial ITI triads arranged by drug self-administration responder group (high, middle, and low) and separated by drug (MDPV and cocaine, respectively). A subject’s baseline (BL) was considered to be the average of premature responses over a 5-day period after reaching stability criteria and immediately before starting ITI Triad Set #1. Abscissa: ITI value (seconds). Ordinate: Premature responses. #P < 0.05 between mid responder and low responder points. Total MDPV rats: n=10 (HR-MDPV = 4, MR-MDPV = 3, LR-MDPV = 3). Total cocaine rats: n=9 (HR-COC = 3, MR-COC = 3, LR-COC = 3).
