很少有研究考察短期压力对奖励/惩罚行为冲动性神经网络的影响。研究了短期压力对女性参与者神经网络的影响。实验组的参与者首先完成一项旨在诱导压力的演讲任务。接下来，所有参与者都进行了奖励（R）/惩罚（P）Go/NoGo任务，而近红外光谱被用来评估大脑激活。结果表明，与P条件相比，R条件下右腹外侧前额叶皮层的Δdeoxy-Hb增加。此外，与对照组相比，实验组在R条件下的假警报反应时间增加。此外，委员会的错误在控制组中增加了显着的R条件相比，P条件。这些结果表明，个体在短期压力下会做出更谨慎和适应性的行为来获得奖励。长期和短期压力似乎对人类基于奖励的决策有不同的影响。在未来，功能磁共振成像可以用来精确地检查短期压力引起的功能连接中可能与冲动有关的变化。
Few studies have examined the influence of short-term stress on neural networks underlying impulsivity in reward/punishment behavior. The influence of short-term stress on neural networks in a sample of female participants was investigated. Participants in the experimental group first completed a speech task intended to induce stress. Next, all participants performed a reward (R)/punishment (P) Go/NoGo task, while near-infrared spectroscopy was used to assess brain activation. Results indicated that Δdeoxy-Hb in the right ventrolateral prefrontal cortex increased in the R condition compared to the P condition. Moreover, false alarm reaction times during the R condition increased in the experimental group compared to the control group. Also, commission errors in the control group increased significantly in the R condition compared to the P condition. These results suggest that individuals make more careful and adaptive actions to obtain rewards when exposed to short-term stress. Long-term and short-term stress appear to have different influences on human reward-based decision making. In the future, fMRI can be used to precisely examine the possible impulsivity-related changes in functional connectivity caused by short-term stress.
