Results for the contextual CSs.

Main effects of stimulus (UCXT, PCXT, SCXT) in the during conditioning (C, day 1), extinction (E, day 2) and the memory tests on day 8 before (Test 1, T1) and after reinstatement (Test 2, T2). Main effects of time are given to index changes from T1 to T2 (T2>T1, indicative of a generalized reinstatement). 1 = all contextual CSs differ significantly from each other (UCXT>PCXT>SCXT). 2 = UCXT and PCXT do not differ significantly from each other but both differ significantly from the SCXT. 3 = UCXT differs significantly from all other contextual CSs, the ITI differs significantly from all contextual CSs. 4 = all contextual CSs differ significantly from the ITI, but not from each other. 5 = UCXT and PCXT do not differ significantly from each other, but both differ significantly from the SCXT, the ITI differs from UCXT and PCXT. 6 = UCTX differs significantly from all other contextual CSs, the ITI differs significantly from all other contexts.
