Schematic of experimental protocol. On each day, subjects performed psychological tests, and then underwent fear conditioning and extinction. Pictures of an office and a library represented conditioning and extinction contexts respectively, whereas the blue (or red) light represented the CS that was paired with the shock and later extinguished. STAI = State-Trait Anxiety Inventory, BAI = Beck Anxiety Inventory, EST = Emotional Stroop Task, MSIT = Multi-Source Interference Task, NEO-FFI = NEO Five Factor Personality Inventory.
