Extinction recall task in the explicit memory attention state. During extinction recall, participants they viewed the CS−, CS+, and four generalization stimuli (GS) that were morphed blends of the CS− and CS+. Task instructions were blocked corresponding to one of two attention states (threat appraisal, explicit memory). Stimuli, task instructions, and response scales were presented simultaneously for 4000 ms with a 200–10000 ms inter-stimulus interval. Note: CS− = non-threat-associated conditioned stimulus; CS+ = threat-associated conditioned stimulus; GS = generalization stimulus.
