Experiment 1. Treatment group abbreviations are based on apparatus configuration (1 or 2c) during acquisition (A) and extinction (E): A1 E1 (N=14); A1 E2c (N=14), A2c E1 (N=16) and A2c E2c (N=16). Error bars indicate the standard error of the mean (±SEM). Total distance traveled in cm (mean, SEM) during behavioral sessions (Pretest, Acquisition, Test 1, Extinction, and Test 2). Acquisition data have been pooled over the two cocaine CS+ and two saline CS− trial types. Extinction data are from trials 1 (1st) and 2 (2nd). Note. ^Saline CS− < Cocaine CS+; *Two-compartment acquisition < One-compartment acquisition; #Two-compartment extinction < One-compartment extinction; p < 0.05, Fig 2A. Cocaine-induced CPP represented as the percent of time spent on the cocaine paired (CS+) floor at the Pretest (Pretest), Post-Acquisition test (Test 1) and Post-Extinction test (Test 2). Note. ^Pretest < Test 1; *A1 < A2c; #E1 < E2c; ps < 0.05, Fig 2B Please see Experiment 1 Results section (Locomotor Activity and Test Preference) for a description of statistical findings.
