Micro-expressions are brief, unconscious facial expressions that reveal a person’s true emotions. They last only a fraction of a second and are difficult to conceal or control. Micro-expressions occur involuntarily and reflect the rapid activation and deactivation of the facial muscles.

Examples include a sudden flinch to indicate fear, a brief frown to indicate sadness, or a flash of disgust to indicate dislike. Micro-expressions can provide insight into a person’s true emotions, even if they are attempting to conceal or mask them.

Micro-expressions have been studied by psychologists and researchers in the field of nonverbal communication and are considered an important tool for detecting deception and understanding emotions. However, interpreting micro-expressions can be challenging and requires specialised training and practice. It is also important to consider other nonverbal cues and context when interpreting micro-expressions.
