Humans subjective experience, often tends to be that the emotions might be clearly recognizable in others or oneself. The perspective has led to recognition and identification of a number of basic emotions that seem universal to all people. However, current debates among various experts in the field seem to question the understanding of what emotions are. Recent studies have resulted to many progression discussions on the different views of emotion over years. Primary emotions accounts for the activation of emotion. They include, anger sadness, fear that are triggered by the brains appraisal by stimulus in perceived survival or targeted goals. Various hypotheses have erupted. For instance, different emotions are being hypothesized to be more of biologically distinct from each other. On contrary feeling based on construction, accounts define emotions of a person to be due to a stimuli response. LeDoux (653) argues that the primary emotions do not exist. However, scholars challenge the perspective and believe that basic emotions are there. They reveal evidences basing on the universals in physiology and expression. The evidences suggest that there is a biological basis on the study of emotions. LeDouxs review of the literature has faultiness as it does not have ideal evidence. According to LeDoux (658), human beings are creatures with emotion and their state of mind can be observed through their facial expression. There is a common belief that there are six basic emotions that are universally under recognition. Scholars argue that they are an interpretation easily done through facial expressions that is independent to the language or culture. The feelings include sadness, happiness, anger, fear, disgust, and surprise. However, the journal published by the University of Glasgow argues that there are only four basic emotions. The universitys conclusion associated range of different studies of muscles around the face. The study involved checking on the signaling of different emotions and the period for the muscle's activation. The study is the first one to examine temporal dynamics of the facial expressions. The study was possible because of the use of the generative face grammar framework developed by the University of Glasgow. According to the institute of neuroscience and psychology, posits that facial expression signals of sadness and happiness seem clearly distinct across fear, time, and surprise. Similarly, they share a common signal that includes wide-open eyes as the early signaling dynamics (Kassam, 66). Anger and disgust tend to share the twisted nose. The signal tends to represent more danger signals. Later in the signalizing of the dynamics, the facial expression tends to transmit signals that more of distinguish the six real facial expressions of the emotion. According to Tettamanti (1809), the emotions results are consistent and are designed on the basis of social evolutionary and biological pressure that optimize their functions. The first danger signals entail the best advantages to others that enable them to have fastest escape. The second aspects tend to be the physiological benefits of the expresser. The wrinkled nose tends to prevent inspiration of any potential harmful particle. The widened eyes facilitate the intake of the visual information that is useful for escape. These signals are enhanced due to face movement
