测量指标:

Outcomes:

指标中文名:

前额叶皮层氧合血红蛋白(HbO?)浓度变化

指标类型:

主要指标

Outcome:

Changes in Oxygenated Hemoglobin (HbO?) Concentration in the Prefrontal Cortex

Type:

Primary indicator

测量时间点:

静息态 30 秒及刺激条件下执行 Stroop 任务过程中

测量方法:

通过 fNIRS 设备同步采集脑血流信号,经 NIRS-KIT 软件预处理后,提取前额叶皮层相关通道的 HbR 浓度变化值,单位为 mmol/L

Measure time point of outcome:

During the Stroop task performed under resting conditions for 30 seconds and under stimulated condit

Measure method:

Simultaneously acquired cerebral blood flow signals via fNIRS equipment were preprocessed using NIRS-KIT software to extract HbR concentration changes in prefrontal cortex-related channels, expressed in mmol/L.

指标中文名:

Stroop 任务正确率

指标类型:

次要指标

Outcome:

Stroop Task Accuracy Rate

Type:

Secondary indicator

测量时间点:

实验数据采集阶段(刺激条件下执行 Stroop 任务过程中)

测量方法:

受试者佩戴 fNIRS 头帽完成对应刺激条件下的 Stroop 任务,由专用任务记录软件自动统计正确完成任务的次数占总任务次数的比例,计算公式为:正确率 = 正确次数 / 总任务次数 ×100%

Measure time point of outcome:

During the Stroop task under stimulating conditions

Measure method:

Participants wore fNIRS headgear while completing the Stroop task under corresponding stimulus conditions. Dedicated task recording software automatically calculated the percentage of correctly completed trials relative to the total number of trials, using the following formula: Accuracy Rate = Number of Correct Trials / Total Number of Trials × 100%

指标中文名:

Stroop 任务反应时

指标类型:

次要指标

Outcome:

Stroop Task Reaction Time

Type:

Secondary indicator

测量时间点:

刺激条件下执行 Stroop 任务过程中

测量方法:

通过 Stroop 任务记录软件,自动记录受试者从呈现任务刺激到做出正确反应的平均时间,单位为毫秒(ms),剔除异常反应数据(如反应时过短 <100ms 或过长> 3000ms)后取平均值

Measure time point of outcome:

During the Stroop task under stimulating conditions

Measure method:

Using Stroop task recording software, the average time from stimulus presentation to correct response is automatically recorded in milliseconds (ms). After excluding outlier response data (e.g., reaction times shorter than <100 ms or longer than >3000 ms), the mean is calculated.

指标中文名:

蒙特利尔认知评估量表(MoCA)注意维度得分量表

指标类型:

次要指标

Outcome:

Montreal Cognitive Assessment (MoCA) Attention Dimension Score Scale

Type:

Secondary indicator

测量时间点:

Stroop 任务结束后

测量方法:

由经过培训的研究人员采用统一的 MoCA 量表,针对注意维度相关条目(如数字广度、字母 cancellation 任务等)进行面对面评估,按量表标准评分规则计分,得分范围 0-6 分,分数越高表示注意功能越好

Measure time point of outcome:

After completing the Stroop task

Measure method:

Trained researchers conduct face-to-face assessments using the standardized MoCA scale, focusing on items related to the attention dimension (such as digit span and letter cancellation tasks). Scoring follows the scale's standard scoring rules, with a range of 0–6 points. Higher scores indicate better attention function.
