What is emotion?</h3>
Emotions are mental states brought on by changes in neurophysiology; they are variously connected to thoughts, feelings, behavioral responses, and a degree of pleasure or displeasure. Currently, there is no accepted definition in science. There are several connections between emotions, mood, temperament, personality, disposition, and creativity.
Research on emotion has increased during the past two decades, with contributions from several academic fields including psychology, medicine, history, sociology of emotions, and computer technology. The numerous theories that aim to explain the genesis, function, and maybe other aspects of emotions have led to more detailed research on the topic. One of the current research areas in the subject of emotion is the development of stimuli and elicitors of emotion.
