1. Discuss how emotions are expressed through facial expressions.
Emotion is one of the most controversial topics in psychology, a source of intense discussion and disagreement from the earliest philosophers and other thinkers to the present day. Most psychologists can probably agree on a description of emotion or what phenomena to include in a discussion of emotion. The list of these parts of emotion is called the components of emotion. These components are distinguished based on physiological or psychological factors and include emotion faces, emotion elicitors, and emotion neural processes. Neither emotion nor their expressions are concepts universally embraced by psychologists. The term expression implies the existence of something that is expressed. The behaviors referenced by expression are part of an organized emotional response, and thus, the term expression captures the behaviors ' role less adequately than a reference to it as an aspect of the emotion reaction. In addition, facial expressions have primarily a communicative function and convey something about intentions or internal state, and I find the connotation of the word expression useful. Facial expressions and emotions are directly linked to each other. Many times, we subconsciously exhibit looks and expressions on our faces that are directly linked to how we are feeling at the time. Though people regularly recognize many distinct emotions, for the most part, research studies have been limited to six basic categories and they are happiness, surprise, sadness, anger, fear, and disgust. The reason for this is grounded in the assumption that only these six categories are differentially represented by our cognitive and social systems. (Knapp, Hall & Horgan, 2014, p.261)
