This article focuses on the processes that lead to awareness of our own emotions, which deserve particular attention in contemporary models of emotional consciousness. The subjective component of emotion, or emotional experience, was for a long time the most neglected aspect in the study of emotions although it already constituted the initial point of discussion in the famous William James still asked question : What is an emotion? More than a century later, contemporary theories debate about this heritage. We examine the successive historic contributions to the question of the determinants of our own emotional experience: from James-Lange bodily changes to cognitive appraisal theories, also relating the major role that the fundamental emotions theory attributed to facial expressions. Twenty years after the debate about primacy of cognition or emotion, both physiological-somatic and cognitive components are integrated in contemporary approaches to emotions. However, their respective degree of implication varies according to the different levels of emotional consciousness which are modelized. It is on the last level that present models focus, level that leads to consciousness of our emotional experience, benefiting from the contributions of cognitive neurosciences. Models differ according to the role devoted to neuronal substrates in determining emotional experience, but they converge on the specification of a last level of consciousness, which is the only one that allows the subject to be conscious of emotion as it is experienced (feeling) and that what he is experiencing is an emotion. Then, different models of emotional consciousness account for different varieties of emotion experience and also for various cases of << unconscious >> emotions, that is occurrence of emotion with a lack of awareness.
