gestualitet

Gestualitet, or gesturality, is the study and phenomenology of gesture in human communication. It refers to the visible movements of the body—particularly the hands, arms, face, and posture—that accompany and participate in conveying meaning. Gestures can accompany speech or occur in silent communication, and they can function independently or interact with linguistic structure. Distinctions are made between co-speech gestures and fully symbolic sign languages, with co-speech gestures often conveying affect, emphasis, or illustrational content.

The field examines types of gestures and their functions, such as signaling focus, organizing turn-taking, expressing attitudes, or illustrating concepts. Gesturality also encompasses facial expressions and body language as integrated aspects of the communicative act. Research emphasizes gesture-speech synchrony, cultural variation, and how gesture contributes to meaning in face-to-face interaction. Theories by researchers such as Adam Kendon and Susan Goldin-Meadow describe how gesture complements or sometimes substitutes spoken language, and how gestures encode information not evident in speech alone.

Methods include video-recorded interactions, gesture coding schemes, and cross-cultural comparisons. Applications span language learning, intercultural communication, human-computer interaction, and the design of avatars and robots that can recognize or produce gestures. Cultural norms influence the interpretation of gestures; some gestures are relatively universal, while others are culture-specific and may lead to miscommunication if assumed universal.

In summary, gestualitet encompasses the study and phenomenon of gesture as a core component of human communication, shaping meaning, interaction, and social understanding beyond words.
