Two studies investigated the impact of recall timing on eyewitness memory. In Study 1, participants viewed a crime video and then completed the Self-Administered Interview (SAI^©) either immediately, after a 24-h delay, after a 1-week delay, or not at all. All participants completed a final recall questionnaire 2 weeks after they had viewed the stimulus video. Study 2 aimed to determine how long the beneficial impact of the SAI^© on witnesses’ long-term memory lasts. Participants watched a crime video and then either completed the SAI^© or did not engage in an immediate recall attempt. Participants then completed a final recall questionnaire after a delay of 24 h, 1 week, 2 weeks, or 1 month. The results indicated that initial recall should be completed within 24 h of an incident and that under these conditions, the beneficial impact of early recall on long-term memory endures for at least 1 month.

两项研究调查了回忆时间对目击者记忆的影响。在研究 1 中，参与者观看了犯罪视频，然后立即、延迟 24 小时、延迟 1 周或根本不完成自我管理访谈 (SAI ^{© )。}所有参与者在观看刺激视频 2 周后完成了最终回忆问卷。研究 2 旨在确定 SAI ^©对证人长期记忆的有益影响持续多长时间。参与者观看了犯罪视频，然后完成了 SAI ^©或没有立即进行召回尝试。然后，参与者在延迟 24 小时、1 周、2 周或 1 个月后完成最终的回忆问卷。结果表明，初始回忆应在事件发生后 24 小时内完成，在这种情况下，早期回忆对长期记忆的有益影响至少持续 1 个月。
