We examined memory and fMRI activity for photos of indoor and outdoor scenes across four time periods to examine these neural changes more carefully. Participants (N = 21) studied scenes 1 hour, 1 day, 1 week, or 1 month before scanning. During scanning, participants viewed scenes, made old/new recognition memory judgments, and gave confidence ratings.为更细致地探究此类神经活动变化，我们针对四个时间周期内的室内外场景照片，分析了参与者的记忆表现与功能磁共振成像（functional magnetic resonance imaging，fMRI）活动。本研究共纳入21名参与者，他们分别在扫描前1小时、1天、1周或1个月完成场景学习任务。扫描期间，参与者依次观看场景图片，完成新旧再认记忆判断，并给出信心评分。
