Emotion has a tremendous impact on our behaviour, sometimes enhancing performance, but other times contributing to human error in dangerous contexts. In addition, some thought processes and behaviours are remarkably resilient to emotional contexts. The effect that emotion has on brain and behaviour seems to depend on a number of factors that are poorly understood. The long-term goal of our research program is to determine how the human brain prioritizes and controls the influence of emotional information to optimize behavioural and cognitive performance. The proposed work will: a) determine the impact of emotional cues on visual awareness; b) distinguish and map neural and cognitive processes that are less susceptible to emotion and emotional distraction; and c) identify ways to exploit those neural and cognitive processes that are less susceptible to distraction. Because this research will identify factors associated with optimizing responses in emotionally charged environments, it will have implications for designing instruments and operating panels for equipment used in stressful environments (e.g., emergency response, defence, life-saving surgical procedures), and for training and selecting personnel that use this equipment.

情绪对我们的行为有着巨大的影响，有时会提高我们的表现，但有时会导致危险环境中的人为错误。此外，一些思维过程和行为对情绪环境具有显着的适应能力。情绪对大脑和行为的影响似乎取决于许多我们知之甚少的因素。我们研究计划的长期目标是确定人脑如何优先考虑和控制情绪信息的影响，以优化行为和认知表现。拟议的工作将：a）确定情感线索对视觉意识的影响； b) 区分和绘制不易受情绪和情绪干扰影响的神经和认知过程； c) 找出利用那些不易受干扰的神经和认知过程的方法。由于这项研究将确定与在情绪激动的环境中优化反应相关的因素，因此它将对压力环境中使用的设备（例如紧急响应、防御、救生外科手术）的仪器和操作面板的设计以及培训和操作产生影响。选择使用该设备的人员。
