本研究调查了视频相关识别如何受到上下文负载（每个上下文呈现的项目数量）、上下文呈现顺序（短视频上下文的连续或随机呈现）和项目提示强度（学习时间长度）的影响。此外，还研究了从视频上下文的静态图像中选择的背景照片的效果。本研究包括 7 个实验，共有 287 名本科生有意研究了一系列不相关的单词。经过 5 分钟的保留间隔后，参与者接受了认知测试。在相同上下文条件下，测试时呈现与研究时相同的视频，而在不同上下文条件下，测试时呈现新视频。当上下文负载为 1 项时，在两个视频实验和一个背景照片实验中发现了一致效果和上下文相关识别辨别力。连续呈现 4 秒视频上下文会在命中率和 d' 方面产生依赖于上下文的效果，上下文负载为 6 个项目，每个项目的学习时间为 4 秒；上下文负载为 18 个项目，每个项目的学习时间为 1.33 (4/3) 秒。相比之下，在这两种情况下都没有发现误报率受到影响。尽管如此，当上下文负载为 18 并且每个项目的研究时间为 4 秒时，未发现命中率、误报率或 d' 受到影响。 4 秒视频上下文的随机呈现产生了一致的效果，但对于上下文负载为 6 或 18 的 d' 没有效果。参与者之间的操作产生了基于上下文的镜像效果。目前的结果表明视频上下文主要充当全局环境上下文，有时也充当局部环境上下文。
The present study investigated how video-dependent recognition is influenced by context load (number of items presented per context), the sequence of context presentation (successive or shuffled presentation of short video contexts), and item cue strength (length of study time). In addition, the effects of background photographs selected from still images of the video contexts were also investigated. The present study includes 7 experiments, in which a total of 287 undergraduates intentionally studied a list of unrelated words. After a filled 5-min retention interval, participants received a recognition test. In the same-context condition, the same video as at study was presented at test, whereas in the different-context condition, new videos were presented at test. With a context load of 1 item, a concordant effect and context dependent-recognition discrimination were found in two video experiments and one background-photograph experiment. Successive presentation of 4-s video contexts produced context-dependent effects in hit rate and in d' with a context load of 6 items and study time of 4 seconds per item, and with a context load of 18 items and study time of 1.33 (4/3) seconds per item. In contrast, no effect was found in the false alarm rate in either condition. Nonetheless, when the context load was 18 and the study time was 4 s per item, no effect was found for the hit rate, false alarm rate, or d'. Shuffled presentation of 4-s video contexts produced a concordant effect but no effect for d' with a context load 6 or 18. Between-participants manipulation produced a context-based mirror effect. The present results imply that video context functions mainly as a global environmental context, and sometimes as a local environmental context.
