摘要

目的

探索不同风险决策能力个体的任务态脑电特征，了解风险决策的神经活动过程，并为决策能力训练的指导提供神经生理学的评估指标。

方法

招募某军校男性学员20名，采用爱荷华赌博任务(Iowa gambling task，IGT)对其风险决策能力进行评估并测量其事件相关电位(event-related potential，ERP)作为神经生理学指标。以行为学指标(净分数)将被试分为高决策能力组和低决策能力组，并分析两组被试在ERP成分上的不同。

结果

随着选择次数的增加，IGT任务行为学绩效不断提升；Oz通道上，高决策能力组的被试在“输”“赢”两种情况下产生的ENW、P200和FRN振幅均高于低决策能力组(

0.05)。

结论

大脑对于结果反馈的早期处理是区分高、低决策能力的重要因素，可以用于评估决策能力训练的有效性。

Abstract

Objective

To explore the characteristics of task-state electroencephalogram (EEG) in individuals with different risky decision-making abilities in order to better understand the neural activity process and provide neurophysiological assessment metrics for the guidance of ability training.

Methods

Twenty male cadets from a military university were recruited to assess their risky decision-making ability and measure their event-related potential (ERP) as a neurophysiological indicator using the Iowa gambling task (IGT) with a 32-channel EEG system. The subjects were divided into high- and low-decision-making ability groups by behavioral indicators (net scores)

and then their differences in ERP components were analyzed between the 2 groups.

Results

The behavioral performance of the IGT was increased as the number of choices increased. On the Oz channel

the participants in the high-decision-ability group produced higher amplitudes of early negative wave (ENW)

P200

and feedback related negativity (FRN) in both "lose" and "win" situations than those in the low-decision-ability group (

0.05).

Conclusion

The brain's early processing of feedback on outcomes is an important factor in distinguishing high and low decision-making abilities

and can be used to assess the effectiveness of decision-making ability training.
