Abstract

Short-form video domains, such as TikTok, may have a degenerate impact on Prospective Memory (PM) performance. This is due to the fast context-switching features that short-form videos present. This study examines the hypothesis that fast context-switching while watching short-form videos contributes to a cognitive decline. The pace of context-switching is the speed at which participants switch between videos. A between-groups design was used with three conditions that varied the pace of context-switching: (1) unlimited context-switching, (2) limited context-switching and (3) control (no short-form video stimulus). Participants' cognitive ability was measured pre and post-video viewing through a combined Lexical Decision (LD) and PM task. Participants (N = 45) were recruited using an experimental participation scheme. To test the hypothesis, linear mixed models were conducted, with LD and PM task response time and accuracy as the criterion and the three context-switching conditions as the predictors. Participants in the unlimited context-switching condition had significantly deteriorated PM performance post-interruption, whereas the limited switching condition had significantly improved PM performance post-interruption. Therefore, fast context-switching is identified as an underlying factor behind PM decline following short-form video use. This could inform the case for the regulation of media platforms with fast context-switching features.

短视频中的情境切换：对前瞻记忆有何影响？

短视频域，如TikTok，可能会对前瞻记忆（PM）性能产生退化影响。这是由于短视频呈现的快速上下文切换特性。这项研究检验了一种假设，即观看短视频时快速切换上下文会导致认知能力下降。上下文切换的速度是指参与者在视频之间切换的速度。采用组间设计，在三种条件下改变上下文切换的速度：(1)无限制的上下文切换，(2)有限的上下文切换和(3)控制（没有短视频刺激）。参与者的认知能力在观看视频前后通过词汇决策（LD）和PM任务进行测量。采用实验性参与方案招募参与者（N = 45）。为了验证这一假设，我们建立了线性混合模型，以LD和PM的任务响应时间和准确性为标准，三种情境切换条件为预测因子。无限情境切换条件下的参与者在中断后的PM绩效显著下降，而有限情境切换条件下的参与者在中断后的PM绩效显著提高。因此，快速上下文切换被认为是短视频使用后PM下降的潜在因素。这可以为监管具有快速上下文切换功能的媒体平台提供依据。

期刊介绍： Memory publishes high quality papers in all areas of memory research. This includes experimental studies of memory (including laboratory-based research, everyday memory studies, and applied memory research), developmental, educational, neuropsychological, clinical and social research on memory. By representing all significant areas of memory research, the journal cuts across the traditional distinctions of psychological research. Memory therefore provides a unique venue for memory researchers to communicate their findings and ideas both to peers within their own research tradition in the study of memory, and also to the wider range of research communities with direct interest in human memory.
