Emotionality is the observable behavioral and physiological component of emotion. It is a measure of a person's emotional reactivity to a stimulus.[2] Most of these responses can be observed by other people, while some emotional responses can only be observed by the person experiencing them.[3] Observable responses to emotion (i.e., smiling) do not have a single meaning. A smile can be used to express happiness or anxiety, while a frown can communicate sadness or anger.[4] Emotionality is often used by experimental psychology researchers to operationalize emotion in research studies.[2]
