Mikroexpressziók

Mikroexpressziók, also known as microexpressions, are brief, involuntary facial expressions that convey emotions or attitudes. They are typically too brief to be consciously controlled or detected, lasting only a fraction of a second. Microexpressions can reveal genuine emotions, even when a person is attempting to conceal them. They are often studied in the fields of psychology, sociology, and neuroscience to understand human behavior and communication.

Microexpressziók are categorized into two main types: spontaneous and posed. Spontaneous microexpressions occur naturally and are difficult to fake, making them valuable in fields such as law enforcement and security. Posed microexpressions, on the other hand, are deliberately performed and can be used to deceive others. Recognizing microexpressions requires training and practice, as they are subtle and can be easily missed.

The study of microexpressions has gained popularity in recent years, with various techniques and tools developed to detect and analyze them. These include the Facial Action Coding System (FACS), which categorizes facial movements into specific action units, and software that uses computer vision to identify microexpressions in real-time. Microexpressions have practical applications in areas such as lie detection, emotional intelligence, and human-computer interaction.
