Emotions are part of everyday life and they have different meanings to different people. They were first studied by Charles Darwin in 1872, he suggested that emotions developed and adapted over time. He wanted to prove that humans and animals had the same emotions so he observed not only their facial expressions, but also their behavior. Charles Darwin and ,a physician, Guillaunme-Benjamin- Amand Duchenne concluded that face expressions worked together to show a few emotions. Duchenne applied electrical current to the faces of his volunteers, by imitating the right combination of facial expressions, he produced more than 60 photographic plates that he believed were emotions. Darwin however disagreed with this, he believed that not all of Duchenne’s slides showed human expressions. To prove his theory, he invited guests and presented 11 of Duchenne’s slides, …show more content…

The guests united and agreed about certain emotions -like sadness, fear, happiness, and surprise- but disagreed about what other slides showed. Darwin then used these results and his own understanding of emotions to write “The Expression of Emotions in Man and Animals”. Emotions consist of not only physical components, but also chemical components. The most important chemical neurotransmitters that control emotions are: Dopamine (C8H11NO2), Norepinephrine (C8H11NO3), Serotonin (C10H12N2O), Glutamic acid (C5H9NO4), and GABA (C4H9NO2). Neurotransmitters impact mood and emotions, it has a connection to health, genetic factors, environmental factors, external emotional stimulus, and nutrition. Dopamine (C8H11NO2) plays a big role in controlling positive emotions, it also contributes to the creating and storing memories. Dopamine is

I agree with the claim “animals have emotions”. There are many example of animals having emotions in the short story “The Most Dangerous Game” by Richard Connell. First, Rainsford was scared and fearful when Zaroff caught him in the tree. This matters, because Rainsford was the animal, the hunted, in this story. This is important because, his emotions would be similar to an animal's emotions in this situation.

Most people say they know how to describe emotions. They feel them all day long, but most know not the scientific definition which states, “emotions are a neural impulse that moves an organism to action”. So technically emotions control most of an organism's actions. Some people hide their emotions or choose to not take actions . In the Herman Hesse’s book, Siddhartha, the main character, Siddhartha, expresses many emotions.

To further exemplify this, “The human body manufactures serotonin, which many researchers believe plays a role in mood balance” (Campbell 1). Antigone takes full accountability for her actions and this is true because of the brain chemicals pushing her to. Additionally, “Serotonin has been labelled the confidence neurochemical. Higher serotonin activity is related to greater feelings of confidence, which in turn gives you the drive to do the things that build self-esteem” (Bishop 11). Serotonin affects the central nervous system and the peripheral nervous system.

No one is capable of choosing their emotions; they come as a result of human nature. This can be seen in our behavior throughout life, from the way babies cry when they miss their parents to the reckless actions of teenagers when they feel the urge to rebel. People begin expressing their feelings before they even start crawling. It is an involuntary reflex that comes naturally and continues to our dying breath. The ability to feel emotion is an aspect of humanity that transcends generations.

Emotions are what propel you forward to reach your goal, but what also stop you from breaking your limits. They are what weigh into our decisions and help lead us to the choices we forever live with. Not only can they determine what we do, but also when and how we do it. At times they are stronger than others, pulling us forward or throwing us back as if we have absolutely no control. Just like in Romeo and Juliet by William Shakespeare, the entire lives of two teenagers led by the emotions that they couldn’t ignore.

James theorized “emotions are perceptions of bodily states” (Oatley, 20). In contrast, Frijda believed emotions were: “not a state, but a whole body process from encoding to action” (Oatley, 22).

Cognition is defined as the mental processes of obtaining and processing knowledge through experiences and information gained from our surroundings whereas biology is the study of the internal and physiological mechanisms of behavior of living organisms. There is a set of theories of emotion psychologists came up with in order to explain how the two factors interact in emotion. For example, Darwin’s evolutionary theory, the James-Lange theory, the Cannon-Bard theory, Le Doux’s theory, Schachter and Singer’s theory, and Lazarus’ theory. In order to determine to what extent cognitive and biological factors influence emotion, the theories that supports both

Harry Harlow performed a study using infant monkeys in order to test feelings of attachment. His results showed that the young monkey preferred the cloth mother for protection and security as well as for all the other basic needs (Harlow, 1958). This experiment is important to emotional expression in infants because it relates to humans as well. Babies have affectional responses to their caretakers, which is primarily their mothers (Harlow, 1958). Infants are also able to react to certain facial expressions made by an adult.

The meaning of emotion has shifted drastically over time. In the 1570s, the word had the meaning of “moving, stirring, agitation”(Online Etymology Dictionary). It was actually in the 1650s when the word again changed to “a sense of strong feeling” (Online Etymology Dictionary). In the academic journal, “Toward a History of Emotion” by David Thorley, it explains an alteration to the word emotion, “The culture shift from passion to emotion that took place between classical and scholastic uses and Enlightenment thinking has been well documented, with most scholars recognized the early modern period as a phrase of tradition”(Thorley 3).
