Emotional expression

An emotional expression is a behavior that communicates an emotional state or attitude. It can be verbal or nonverbal, and can occur with or without self-awareness. Emotional expressions include facial movements like smiling or scowling, simple behaviors like crying, laughing, or saying "thank you," and more complex behaviors like writing a letter or giving a gift. Individuals have some conscious control of their emotional expressions; however, they need not have conscious awareness of their emotional or affective state in order to express emotion.

Researchers in psychology have proposed many different and often competing theoretical models to explain emotions and emotional expression, going as far back as Charles Darwin's discussion of emotion as an evolved capacity. Though there is no universally accepted theory of emotion, theorists in emotion agree that experience of emotions and expression of them in a variety of ways, such as with voices, faces, and bodies, is key to human communication. The cultural norms and beliefs of a society also affect and shape the emotional expressions of its members, and expressions appropriate and important in one culture may be taboo in another.

High expressiveness could be useful in constructively resolving relationship-related conflict.

There are many different theories about the nature of emotion and the way that it is represented in the brain and body. Of the elements that distinguish between the theories of emotion, perhaps the most salient is differing perspectives on emotional expression.

Some theories about emotion consider emotions to be biologically basic and stable across people and cultures. These are often called "basic emotion" perspectives because they view emotion as biologically basic. From this perspective, an individual's emotional expressions are sufficient to determine a person's internal, emotional state. If a person is smiling, they are happy. If a person is crying, they are sad. Each emotion has a consistent and specific pattern of expressions, and that pattern of responses is only expressed during that emotion and not during other emotions. Facial emotional expressions are particularly salient stimuli for transferring important nonverbal signals to others. For that reason, emotional expressions are the best direct indicators of affective attitudes and dispositions. There is growing evidence that brain regions generally engaged in the processing of emotional information are also activated during the processing of facial emotions.

Some theories of emotion take the stance that emotional expression is more flexible, and that there is a cognitive component to emotion. These theories account for the malleability in emotion by proposing that humans appraise situations and, depending on the result of their appraisal, different emotions and the corresponding expressions of emotion are triggered. The tendency to appraise certain situations as one emotion or another can vary by person and culture; however, appraisal models still maintain that there are basic responses that are specific and consistent to each emotion that humans feel.

Other theories of emotion propose that emotions are constructed based upon the person, situation, culture, and past experiences, and that there are no preset emotional responses that are consistent and specific to one emotion or another.

The basic model of emotions finds its roots in Charles Darwin's The Expression of Emotions in Man and Animals. Darwin claimed that the expression of emotions involves many systems: facial expression, behavioral response, and physical responses, which include physiological, postural, and vocal changes. Most importantly, Darwin claimed that emotional expression was consistent with his theories on evolution and thus, the expression of emotion is universal and should therefore be expressed similarly across race or culture. This is known as the universality hypothesis. Lastly, primates and animals exhibit precursors of muscle actions of the facial expressions of humans.
