Figure 1A. The experimental timeline used in Anderson et al. (2006) for each encoding trial. Modulator items were rated on arousal during each trial. Retrograde enhancement of memory was observed for faces and houses that preceded emotionally arousing scenes in a one-week delayed recognition test.

Figure 1B. The experimental timeline used in Hurlemann et al. (2005) for each encoding trial (list). Retrograde amnesia was observed for items that preceded emotionally arousing oddballs in tests of immediate free recall after each trial.
