体感游戏训练对生物运动工作记忆容量的影响

The Influence of Motion Sensing Game Training on the Working Memory Capacity of Biological Motion

传递生物体运动信息的生物运动在工作记忆中有着独立于一般视觉客体的存储空间。尽管研究发现电子游戏训练可提高工作记忆(如一般视觉客体)容量,但尚未有研究探讨游戏训练对生物运动工作记忆容量的影响。本研究采用Kinect体感游戏训练,首次对该问题进行探讨。实验中控制组被试与实验组被试均先后做两次生物运动记忆实验,但实验组在第一次实验后进行为期14天的体感游戏训练。结果发现,尽管生物运动工作记忆绩效在后测时较前测有显著上升,但是游戏训练并未显著提高实验组的记忆绩效,说明生物运动工作记忆并不受体感交互游戏训练影响。

Biological motion has an independent storage buffer in working memory（ WM） from common visual objects（ e. g.,color,location）.While it has been revealed that video games can considerably increase the WM capacity of common visual objects,no study has explored whether video games improve the WM capacity of biological motion. Here we closed this gap by requiring two groups（ control vs. training group） of participants to finish a task measuring the WM capacity of biological motion twice with a gap of 14-days. Critically,during the 14 days the training group had to perform Kinect-based motion sensing games 1hour / day. It is found that WM performance significantly increased in the second measurement relative to the first one,and it was not modulated by the training experience. These results suggest that motion sensing game training does not selectively improve the WM capacity of biological motion.
