The article "Mimik und Emotion" by Carsten M. Klingner and Orlando Guntinas-Lichius explores the intricate relationship between facial expressions and emotions. It highlights how facial expressions are uniquely human in their ability to convey and communicate emotions, with basic emotions being similarly expressed across cultures and shared with other mammals, suggesting a genetic origin. However, recent studies also reveal cultural influences and differences. The recognition and expression of emotions from facial expressions occur within a complex cerebral network. Neurological and psychiatric disorders can significantly disrupt this network, affecting the coupling of facial expressions and emotions. Wearing masks further limits our ability to convey and recognize emotions through facial expressions. The article discusses the distinction between voluntary and involuntary facial movements, particularly microexpressions, which are brief, unconscious facial movements that can reveal true emotions despite attempts to hide them. These microexpressions are ideal for automated analysis and have been studied in various contexts, including safety-relevant areas. Cultural differences in facial expressions are also examined, noting that Western studies have dominated the field. The influence of diseases on facial expressions and emotion recognition is discussed, with examples such as Parkinson's disease and its impact on facial motor functions and emotion processing. The article also explores the use of facial expressions in other species, the neural processing of emotional faces, and the societal implications of interpreting facial expressions. It concludes by emphasizing the importance of recognizing emotions in videos and the potential for automated analysis in various fields, including business negotiations, psychiatric conversations, and forensics.The article "Mimik und Emotion" by Carsten M.
