Pre-exposure to non-fearful models impaired the formation of contextual fear memory. The NF group showed persistent reduction of fear after training, extinction and a shock reminder. On the reinstatement test there was a significant increase of freezing when compared to the sixth extinction trial (E6 ; ***p < 0.001), but not to the first extinction test (E1). In spite of the increase of freezing after the shock reminder, the NF group still showed a significantly lower freezing when compared to the No-PE group (*p = 0.018).
