The retrieval-extinction paradigm based on the memory reconsolidation theory can effectively weaken the maladaptive fear memory. Gender difference is a key variable in the study of individual difference, but there are few studies on gender difference in the retrieval-extinction paradigm. In this study, stereoscopic geometry was used as the conditioned stimulus, electric shock as the unconditioned stimulus, skin conductance response as the fear response index. The results showed that all the participants in the retrieval-extinction group successfully inhibited the fear relapse in the fear spontaneous recovery test, but only the female participants inhibited the fear relapse in the reinstatement test. The results showed that the retrieval-extinction paradigm had a significant effect on inhibiting the spontaneous recovery of fear, and the fear reduction effect on reinstatement test of female was better than that of male.
