In aviation, where reaction time can be crucial, body language plays a significant role in communication. After all, we perceive information not only from words but also from gestures, facial expressions, and body movements.
In an airplane cabin, body language can be especially useful for transmitting non-urgent information or when words might be unclear due to noise. For example, a pilot might point a finger at a certain system or instrument that needs attention, or make a gesture signaling the need to perform a procedure.
But body language is also important for general understanding and good teamwork. Often, we immediately feel when something is wrong based on a colleague's gestures or facial expressions. It's important to correctly interpret these signals and respond to them.
Interestingly, research shows that the perception of body language can be intuitive. In one experiment, participants were shown photographs of people and asked to assess their emotions based solely on body movements and facial expressions. The results showed that most people are capable of accurately determining the emotions of others, even without words.
Non-verbal communication, such as body language, "complements" any verbal communication during face-to-face interaction, and it conveys a subjective message (sometimes obvious, sometimes subtle) that may contradict the objective one. Otherwise known as discrepancy.
