摘要

目的

探讨基于虚拟现实（virtual reality，VR）技术的陆军军人工作记忆训练系统的可行性及有效性。

方法

利用VR技术将驾车任务与工作记忆任务（n-back、数字转换和色词Stroop任务）相结合，构建工作记忆VR训练系统，采用整群随机抽样法选取30名陆军军人体验VR场景并完成Likert7级评分VR场景评价表。采用整群随机抽样法选取60名陆军军人，分为VR训练组和对照组，VR训练组运用工作记忆VR训练系统进行训练，对照组不给予任何处理。训练前后被试均完成运算词语广度、活动记忆、局部-全局和GO/NOGO任务。采用描述性统计分析、独立样本t检验、配对样本t检验、Mann-Whitney U检验和Wilcoxon符号秩和检验对结果进行分析。

结果

① 30名被试在VR场景评价表 9个分量表上的均值都大于中间值4（

=4.180~6.183）；②VR训练组后测的运算词语广度任务成绩（

0.01）、活动记忆任务正确率（

0.05）均显著大于后测，前测的GO/NOGO任务误报数显著大于后测（

0.05），局部-全局任务前后测的转换量差异无统计学意义（

=0.091）。③对照组前后测任务成绩差异均无统计学意义（

0.05）。

结论

本研究构建的陆军军人工作记忆VR训练系统具有可行性和有效性。

Abstract

Objective

To investigate the feasibility and validity of working memory training system based on virtual reality (VR) technology for army soldiers.

Methods

MethodsA VR-based working memory training system was established by combining driving task with working memory tasks (including n-back

more-odd shifting and Stroop task). A total of 30 army soldiers selected by cluster random sampling were asked to experience the VR scene and fill in a Likert 7 grade VR scene rating scale including 9 subscales. Then another 60 army soldiers selected by cluster random sampling were randomly divided into VR training group and control group. The soldiers from the former group were given working memory VR training

and those from the latter received no training. All the subjects completed operation-word span task

active memory task

local-global task and GO/NOGO task before and after training. Descriptive statistical analysis

independent sample t-test

paired sample t-test

Mann-Whitney U test and Wilcoxon signed-rank test were adopted to statistically analyze the results.

Results

① The average values of the 9 subscales in the VR scene rating scale were greater than the median value 4 (

=4.180~6.183); ② After the training

the performance of operation-word span task (

0.01) and correct rate of active memory task (

0.05) were increased

and the false re

ports of GO/NOGO task (

0.05) were decreased in the VR training group

and no statistical difference was seen between the performance of local-global task before and after training (

=0.091). ③There were no significant differences in above indicators in the control group before and after training (

0.05).

Conclusion

The VR-based working memory training system is feasible and effective for army soldiers.
