摘要

最近的研究表明，高度的考试焦虑会降低学生的考试成绩，因此对其诊断对学业进步至关重要。22名志愿者，男9名，女13名，平均年龄24.195岁，标准差2.25，随机分为“试验组”和“对照组”。当所有参与者睁着眼睛同时进行心算测试时，他们的脑电图（EEG）被记录在19个通道中。提取放松和焦虑状态下所有Brodmann区域的Theta与beta功率比，并采用Wilcoxon符号秩检验的非参数统计进行检验。swLORETA分析显示，在静息状态和数学任务中，实验组的颞叶、岛叶和顶叶有显著差异（p <； 0.05）。颞叶处理语言和听觉信息，顶叶管理意识和感觉处理，岛叶皮层帮助决策。因此，理解听觉和环境信息对人们在数学测试中的表现有影响作用。

Evaluating the effect of mathematical anxiety in healthy subjects on brain signal using swLORETA analysis

Recent studies indicate that high test anxiety lowers students' exam grades, making its diagnosis crucial for academic progress. 22 volunteers consisting of 9 men and 13 women with an average age of 24.195 years old and a standard deviation of 2.25 were randomly put in two “test” and “control” groups. An electroencephalogram (EEG) was recorded in 19 channels from all participants while they had their eyes open and were simultaneously taking the mental math test. Theta to beta power ratio for all Brodmann areas in relaxing and anxiety states was extracted and examined by employing the non-parametric statistics of the Wilcoxon signed-rank test. The swLORETA analysis revealed a significant difference (p < 0.05) in the temporal, insular, and parietal lobes between the resting state and the math task in the test group. The temporal lobe processes language and auditory information, the parietal lobe manages awareness and sensory processing, and the insular cortex aids in decision-making. Therefore, understanding auditory and environmental information can play an influential role in people's performance during a math test.

期刊介绍： Learning and Motivation features original experimental research devoted to the analysis of basic phenomena and mechanisms of learning, memory, and motivation. These studies, involving either animal or human subjects, examine behavioral, biological, and evolutionary influences on the learning and motivation processes, and often report on an integrated series of experiments that advance knowledge in this field. Theoretical papers and shorter reports are also considered.
