Gestures and facial expressions: understanding body language

In short: Gestures and facial expressions often convey more information than spoken words and significantly influence how a statement is perceived. Body language isn’t universal, though — it’s partly shaped by culture.

In more detail: Studies show that nonverbal signals are often weighted more heavily than the spoken words themselves when messages conflict.

In detail

• Micro-expressions: Very brief, involuntary facial expressions can reveal genuine emotions even when someone tries to hide them.
• Open and closed posture: Crossed arms or a turned-away body often appear defensive, while an open posture signals approachability.
• Eye contact: The appropriate duration and intensity of eye contact vary greatly between cultures and can be perceived as respectful or intrusive.
• Universal emotions: According to research, basic emotions like joy, sadness, anger, and fear are expressed facially in relatively similar ways across cultures.
• Gesture meaning by culture: Some gestures considered friendly in one country can be offensive or confusing in others.
• Congruence: When body language and spoken words don’t match, this is often unconsciously perceived as uncertainty or insincerity.
• Deliberate use: Rhetoric training uses targeted body language to make statements more credible and persuasive (rhetorik-grundlagen-ueberzeugend-sprechen, netiquette-online-kommunikation).
