For T1, a near-significant preference for the initially cocaine-associated compartment over the saline-associated compartment was found ( P = 0.054, F = 4.33), whereas tests T2, T3 and T4 did not yield any significant preference for the cocaine-associated compartment any more ( P > 0.1) (Table 2 ).
