Note. Time bin loadings in bold indicate early and late components (factors). Variance = variance explained by each factor. MFT = misses in FT condition (i.e., old stimuli reported as new); MNT = misses in NT condition (i.e., new stimuli reported as old); FANT = false alarms in NT condition (i.e., old stimuli reported as new).
