Schematic depiction of the fear extinction retention paradigm. In each phase, participants view a computer monitor with an image of a room containing an unlit lamp for 6 seconds. The lamp then lights up to one of two colors for 12 seconds. During conditioning, one color of the lamp (CS+) is paired with a 500 ms electric shock in context 1. During extinction training, the CS+ is presented in context 2 without the US, as is the CS- (not shown). This procedure is repeated in context 2 during extinction recall, and in context 1 during renewal.
