A primary challenge for alibi-generation research is establishing the ground truth of real-world events of interest. In the current study, we used a smartphone app to record data on adult participants ( = 51) for a month prior to a memory test. The app captured accelerometry data, GPS locations, and audio environments every 10 min. After a week-long retention interval, we asked participants to identify where they were at a given time from among four alternatives. Participants were incorrect 36% of the time. Furthermore, our forced-choice procedure allowed us to conduct a conditional logit analysis to assess the different aspects of the events that the participants experienced and their relative importance to the decision process. We found strong evidence that participants confuse days across weeks. In addition, people often confused weeks in general and also hours across days. Similarity of location induced more errors than similarity of audio environments or movement types.
一个主要的挑战对于不在场证明生成研究是建立真实世界事件的事实真相感兴趣。在本研究中，我们使用智能手机应用程序来记录数据之前一个月的成人参与者（= 51）的记忆测试。该应用程序捕获加速度计数据，GPS 位置和音频环境每 10 分钟。一周后的保留间隔，我们要求参与者从四个选项中识别给定时间他们在哪里。参与者错误的时间 36%。此外，我们的强制选择过程允许我们进行条件逻辑分析来评估参与者经历的事件的不同方面及其对决策过程的相对重要性。我们发现有强有力的证据表明，参与者混淆了周之间的日期。此外，人们经常混淆一般的周和一天中的小时。位置的相似性导致更多的错误比音频环境或运动类型的相似性。
