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巨大的影响，有时会提高表现，但有时会在危险的环境中导致人为错误。此外，一些思维过程和行为对情绪环境有很强的适应能力。情绪对大脑和行为的影响似乎取决于许多鲜为人知的因素。我们研究计划的长期目标是确定人类大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。这项拟议的工作将：a)确定情绪线索对视觉意识的影响；b)区分和描绘较不容易受情绪和情绪干扰影响的神经和认知过程；以及c)找出利用那些较不容易受分心影响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，因此它将对在压力环境中使用的设备(例如，紧急响应、防御、救命外科手术)设计仪器和操作面板，以及培训和选择使用这种设备的人员产生影响。
