This project will examine whether brain stimulation and perceptual training can help to improve social perception abilities in healthy adults and atypical groups.Even in the most fleeting social interaction, we are confronted with a wide array of social signals several of which are displayed by the face. Our ability to successfully interpret and use these signals is a critical feature of our everyday lives. In recent years we have made large strides in understanding brain mechanisms that we use for a range of our social perception abilities (e.g. emotion perception, person perception). This project builds on this by examining whether increasing neural activity in these brain regions can enhance our social perception abilities. To do this, the project will use novel brain stimulation techniques called transcranial direct current stimulation (tDCS) and transcranial random noise stimulation (tRNS). These techniques involve a small current (1-2milliamps) being passed between two rubber pads that are placed on the scalp. When current flows between the two pads, the brain area underneath them becomes more excitable. This makes the particular brain area more responsive to signals that it processes and it has been shown that if the excitatory stimulation is given while someone is training / learning a new skill (that recruits the brain area being stimulated) then the benefits of learning / training are enhanced and occur more rapidly. The project will use these types to brain stimulation to examine whether we can facilitate face recognition and facial emotion recognition. This will include studies in typical and atypical groups (e.g. in developmental prosopagnosia - where individuals are unable to perceive the facial identities of other people). The project will also build upon recent studies using face-training paradigms to improve facial identity and emotion processing abilities, by stimulating the brain during training. Based upon findings in other domains, it is predicted that increasing excitability in brain areas shown to be involved in each task (i.e. person perception and emotion perception) will enhance specific social perception skills. It is also expected that pairing social perception training paradigms with brain stimulation will lead to training effects being boosted and lasting longer. The findings will therefore provide insights into the mechanisms of the brain that contribute to our social perception abilities and determine whether we can influence them in order facilitate social perception abilities in typical and atypical groups.

该项目将研究大脑刺激和知觉训练是否有助于提高健康成人和非典型群体的社会知觉能力。即使是在最短暂的社交互动中，我们也会面对各种各样的社交信号，其中一些信号是通过面部表现出来的。我们成功解释和使用这些信号的能力是我们日常生活的一个关键特征。近年来，我们在理解大脑机制方面取得了很大进展，这些机制用于我们的一系列社会感知能力（例如情绪感知，人的感知）。这个项目建立在这个基础上，研究增加这些大脑区域的神经活动是否能提高我们的社会感知能力。为此，该项目将使用新的脑刺激技术，即经颅直流电刺激（tDCS）和经颅随机噪声刺激（tRNS）。这些技术包括在放置在头皮上的两个橡胶垫之间通过一个小电流（1-2毫安）。当电流在两个电垫之间流动时，它们下面的大脑区域变得更容易兴奋。这使得特定的大脑区域对它处理的信号更敏感，并且已经表明，如果在某人训练/学习新技能时给予兴奋性刺激（招募被刺激的大脑区域），那么学习/训练的好处就会增强并且更快地发生。该项目将利用这些类型的大脑刺激来检验我们是否可以促进面部识别和面部情绪识别。这将包括对典型和非典型群体的研究（例如，在发展性面孔失认症中，个体无法感知他人的面部身份）。该项目还将以最近的研究为基础，利用面部训练范式，通过在训练过程中刺激大脑，提高面部识别和情绪处理能力。根据其他领域的研究结果，我们预测，参与每项任务（即人感知和情绪感知）的大脑区域的兴奋性增加将提高特定的社会感知技能。将社会知觉训练模式与脑刺激相结合，可以提高训练效果并使其持续时间更长。因此，这些发现将提供对大脑机制的见解，这些机制有助于我们的社会感知能力，并确定我们是否可以影响它们，以促进典型和非典型群体的社会感知能力。
