噪声暴露时间对矿工风险感知的影响:来自fNIRS的证据
The effect of noise exposure duration on miners' risk perception:Evidence from fNIRS
摘要
Abstract
This study attempts to improve the risk perception level of miners.We divided the noise ex-posure into 4 phases:0 min,15 min,30 min and 45 min,and designed risk perception task test under different noise exposure time based on literature review and experiments.We collected the functional near-infrared spectroscopy(fNIRS)and the behavioral data of the subjects and conducted paired t-tests,non-parametric tests and Pearson correlation analysis to investigate how different noise exposure time affects the risk perception level of miners.Results show that:(1)Noise exposure time posed sig-nificant impact on the accuracy of the subjects,exhibiting an initial increase and subsequent decrease over time;(2)Noise exposure time significantly activated the channels located in orbital frontal lobe(OFC),frontal polar region(FPC)and dorsolateral prefrontal lobe(dlPFC)in the risk perception task,and the activation level of the left hemisphere was slightly higher than that of the right hemi-sphere;(3)The brain regions showed a stage-by-stage collaborative relationship under different noise exposure time.The dorsolateral prefrontal and frontal pole regions collaborated during the noiseless stage.The collaboration between the frontal pole region and orbital frontal region was enhanced at 15 minutes of noise exposure,and the collaboration between the left and right hemispheres of the dorsolat-eral prefrontal was enhanced at the 30-minute and 45-minute stages.关键词
