Fig. 5: Study procedures.
From: Both slow wave and rapid eye movement sleep contribute to emotional memory consolidation
A Timeline of the study procedures for different groups are depicted. In all groups, the first visit started at 11:00 AM. After training and practice, a baseline test (T1) was carried out immediately before the nap. The first retest (T2) was approximately 45 min after waking up. The second retest (T3) was approximately 1 week after the first visit. B During training, participants passively viewed emotional or neutral pictures appearing at different locations on a grid, while a paired sound was played. During practice and test, pictures appeared in the center of the screen, and participants were asked to move them to their correct location.
