marginally significantP = 0.056
In the LI group, an extinction source memory bias (the bias to attribute more CS + than CS − to the extinction phase) was negatively related to selective enhancement in LI for items encoded in preconditioning ( t (198) = −4.27, P < 0.001), conditioning ( t (198) = −3.07, P = 0.003) and marginally significant in extinction ( t (198) = −1.92, P = 0.056).
