The face has a functional value transmitting information about our emotional state. Recognition of emotional facial expressions is crucial, allowing us to adapt our behaviour accordingly. The current program is centered on the processing and recognition of emotional facial expressions. The recognition rates for the expressions of the basic emotions such as happiness, anger, disgust, fear, surprise and sadness are high, surpassing chance level. However, not all emotions are recognized equally well. Variations are observed between emotions with happiness being the most accurately recognized, followed by anger, surprise, disgust, sadness, and finally, fear. While the pattern of errors and general recognition rates seem clear, the underlying processes are not well understood. The main goal of the current program is to test a new comprehensive framework called the Attentional-Perceptual Scan-path for Emotion Recognition (APSER) that I am proposing. According to APSER, recognition of emotional facial expressions is accomplished by sequentially attending to individual features of the facial expression. Individual features would be integrated into a unified representation and new features would be processed until a label is selected. The first axis of the research program includes experiments to explore attentional-perceptual mechanisms. In effect, while the role of attentional-perceptual mechanisms in the recognition of emotional facial expressions is undisputable, it remains unclear how they operate. The second axis will test the new assumptions of APSER, which stipulates that recognition is based on the sequential attention to and perception of individual features of the facial expression as a function of the emotion expressed until the accurate label is selected. The third axis of the program focuses on the applicability of APSER from a developmental perspective as research has shown that children process emotional facial expressions differently than adult.

面部具有传递我们情绪状态信息的功能价值。识别情绪面部表情至关重要，使我们能够相应地调整我们的行为。目前的计划是集中在情绪面部表情的处理和识别。对快乐、愤怒、厌恶、恐惧、惊讶和悲伤等基本情绪的表情识别率都很高，超过了偶然水平。然而，并不是所有的情绪都能被同样好地识别。观察到情绪之间的变化，幸福是最准确的识别，其次是愤怒，惊讶，厌恶，悲伤，最后是恐惧。虽然错误的模式和一般的识别率似乎很清楚，但基本的过程还没有得到很好的理解。当前项目的主要目标是测试我提出的一个新的综合框架，称为情绪识别的注意-感知扫描路径（APSER）。根据APSER，情感面部表情的识别是通过顺序地关注面部表情的个体特征来完成的。单个特征将被集成到一个统一的表示中，新的特征将被处理，直到选择一个标签。研究计划的第一轴包括探索注意知觉机制的实验。实际上，虽然注意力感知机制在识别情绪面部表情中的作用是无可争议的，但它们是如何运作的仍然不清楚。第二个轴将测试APSER的新假设，它规定识别是基于对面部表情的个体特征的顺序注意和感知，作为所表达的情感的函数，直到选择准确的标签。该计划的第三个轴侧重于从发展的角度来看APSER的适用性，因为研究表明，儿童处理情绪面部表情与成人不同。
