The author of the article has defined emotions in numerous ways, and he has accepted that emotions can be described as facial expression, subjective and physiology experiences. I strongly agree with this description since emotions are also referred to as feelings and merely a collection of experiences like grief, joy, love, hate, panic, trust, joy and fear. Since emotions are a specific response to a particular occurrence which usual takes a shorter duration, the author can be justified as being right in the description of the emotions as a physiological experience. In this case the emotions results due to persons physiological response, like when an individual releases sweat following intense activity, or adrenaline in response to anxiety.
Furthermore I accept the author’s analogy of emotions when he says that emotions are subjective. Every person experiences emotions, and no person experience the same response for the same experience. The description of emotion as subjective is thus a constituent of emotions which may refers to an individual experiences and feelings, and usually it is not easy to conclusively measure or describe each and every person’s feelings. Additionally, I acknowledge the fact that emotions are subjective because no one can observe subjective emotion but the person who is experiencing the emotion can describe what he/she experiences. However, every person has got a different description of the emotions experienced as well as different interpretation of the feelings he is going through. A good example is two persons who are in love, they will not share the same description of what they feel because their feelings are subjective and depend on their individuality.
Unlike subjective emotions, physiological emotions can be measured. For instance, scientist can easily measure the heart beat of a person, they can also measure the adrenaline released during anxiety and sweat. On this basis, emotions can be likened to the biological processes in which hormones are produced to bring different feelings like in the case of adrenaline produced to prepare a person to either run away or take a flight. However, as much as these emotions can be measured, I disagree with the articles acceptance that emotions are the same for each feeling. A number of different emotions can result into similar physical reaction.
As noted by the author in his description of what emotions are, I agree that emotions can be in form of facial expression. This is because; a person may express the emotion he/she experiences as an outward behavior. Therefore, facial expression, restlessness, body language and voice variation can be forms of expressive behavior in which an individual shows the emotions he /she is experiencing. Owing to the diverse description and occurrence of emotions it is very wrong to accept valence and intensity as the most important aspects of emotions. And just as have explained above, there cannot be unimodal emotions for humans since different emotions can lead to similar feelings.
Therefore, as noted by neuroscientists and psychological findings, to understand emotions well one must endeavor to find answers to some questions. For instance, what trait is exhibited and in what ways the traits exhibited in response to a particular experience. Moreover, understanding is needed to tell how the identified trait has developed in the history of the particular specie and to some extents the factors that have shaped the trait. For example, in understanding individuals reaction to anxiety, the hormone adrenaline must be studied, its contribution to the increased flight and the way it can be lowered once the danger is away.
