This paper presents a cognitive psychology experiment to explore the differences between 2D and virtual reality (VR) film editing techniques. We recruited sixteen volunteers to view a range of different display modes and edit types of experimental material. An electroencephalogram (EEG) was recorded simultaneously while the participants watched. Subjective results showed that the VR mode reflects higher load scores, particularly in the effort dimension. Different editing types have no effect on subjective immersion scores. The VR mode elicited stronger EEG energy, with differences concentrated in the occipital, parietal, and central regions. On the basis of this, visual evoked potential (VEP) analyses were conducted, and the results indicated that VR mode triggered greater spatial attention, while editing in 2D mode induced stronger semantic updating and active understanding. Furthermore, we found that while the effect of different edit types in both display modes is similar, cross-axis editing triggered greater cognitive violations than continuity editing, which could serve as scientific theoretical support for the development of future VR film editing techniques.
本研究通过认知心理学实验,探讨二维(2D)和虚拟现实(VR)电影剪辑技术的差异。我们招募了 16 名志愿者,让他们观看不同的显示模式和实验材料的编辑类型。参与者观看的同时,我们同步记录了脑电图(EEG)。主观结果表明,VR 模式反映出更高的负荷评分,特别是在努力维度上。不同的编辑类型对主观沉浸感评分没有影响。VR 模式引起更强的 EEG 能量,差异集中在枕部、顶叶和中央区域。在此基础上,我们进行了视觉诱发电位(VEP)分析,结果表明 VR 模式引发了更强的空间注意力,而在 2D 模式下进行编辑则引起了更强的语义更新和主动理解。此外,我们发现,尽管两种显示模式下不同编辑类型的效果相似,但交叉轴编辑比连续性编辑引发更大的认知违反,这可为未来 VR 电影剪辑技术的发展提供科学理论支持。
