Posture (psychology)

In humans, posture can provide a significant amount of important information through nonverbal communication. Psychological studies have also demonstrated the effects of body posture on emotions. This research can be traced back to Charles Darwin's studies of emotion and movement in humans and animals. Currently, many studies have shown that certain patterns of body movements are indicative of specific emotions. Researchers studied sign language and found that even non-sign language users can determine emotions from only hand movements. Another example is the fact that anger is characterized by forward whole body movement. The theories that guide research in this field are the self-validation or perception theory and the embodied emotion theory.

Physical posture and emotion have been studied using two similar techniques. The first method involves the participant viewing videotaped actors performing certain actions and the second method involves having the participant sit in a certain posture and then self-reporting their emotions. In the first method, actors portray and record certain body movements. Participants must view the video and decipher the emotion they believe is being portrayed. In the second method, participants are told to assume a certain body posture and then must complete a survey on their current affective state. Other methods include using neuroscience techniques, such as fMRI's to determine how posture and emotions expressions can affect brain imaging. Another method that is growing in use involves using dancers as 'actors' and having participants observe and determine the emotion the dancer is conveying.

In humans, one of the means of communication is the posture of the body, in addition to facial expressions, personal distances, gestures and body movements. Posture conveys information about:

Posture can signal both the enduring characteristics of a person (character, temperament, etc.), and his or her current emotions and attitudes. Therefore, posture can be considered in the context of a given situation, and independently of it.

Posture as information about the current state of a person's emotions and attitudes should be analyzed in the context of other messages, both verbal and nonverbal as well as that person's cultural and social norms.
