Abstract

Aim

The study investigated the cortical activity changes and time production task performance induced by changes in motion speed of a non-immersive 3D virtual stimulus.

Material and methods

Twenty-one individuals were participated in the crossover study with the visual-time reproduction task under three-speed conditions: original, slow and fast virtual stimulus. In addition, the electroencephalographic analysis of the theta band power in the dorsolateral prefrontal cortex was done simultaneously with time production task execution.

Results

The results demonstrated that in the slow speed condition, there is an increase in the error in the time production task after virtual reality (p < 0.05). There is also increased EEG theta power in the right dorsolateral prefrontal cortex in all speed conditions (p < 0.05).

Conclusions

We propose that the modulations of speed of virtual stimulus may underlie the accumulation of temporal pulses, which could be responsible for changes in the performance of the production task of the time intervals and a substantial increase in right dorsolateral prefrontal cortex activity related to attention and memory, acting in cognitive domains of supraseconds.

非沉浸式 3D 虚拟刺激改变了时间生产任务的表现并增加了背外侧前额叶皮层的 EEG θ 功率

摘要

目标

该研究调查了由非沉浸式 3D 虚拟刺激的运动速度变化引起的皮层活动变化和时间生产任务性能。

材料与方法

21 个人参与了在三种速度条件下的视觉时间再现任务的交叉研究：原始、慢速和快速虚拟刺激。此外，背外侧前额叶皮层θ波段功率的脑电图分析与时间生产任务执行同时进行。

结果

结果表明，在慢速条件下，虚拟现实后时间生产任务的误差有所增加（p  < 0.05）。在所有速度条件下，右背外侧前额叶皮层的 EEG θ 功率也增加（p  < 0.05）。

结论

我们提出，虚拟刺激速度的调制可能是时间脉冲积累的基础，这可能是时间间隔生产任务性能的变化以及与注意力和记忆相关的右背外侧前额叶皮层活动显着增加的原因。 ，作用于超秒的认知领域。
