Abstract This study was carried out to discuss the relationship between emotions and humans, particularly whether emotions and their physiological counterparts have evolved in everyone to show a generalized response in similar stressful situations and to show how negative emotions are more apparent to people than positive ones and that women detect emotions better than men. The study was conducted on 14 brain and behavior students at Brock University through a test involving listening to relationship scenarios and then recording how you would feel emotionally and physically, as well as a test involving the description of the emotion that the person transmits with just their eyes. Results showed that the tests depicted humans as more emotionally competent in dealing with negative emotions and women as more emotionally competent than men, and all subjects showed relationships between their physical and emotional descriptors showing generalization of feelings and effects. Emotions, a feeling that everyone experiences, but although unique to each person, they share common similarities that make them both desirable and unbearable. This is not only apparent in humans, but also in other animals: dogs, cats, primates and even mice show signs of emotions. These emotions are present during happiness, sadness, anger, fear or disgust. Like most animals in which we evolved emotion, Darwin's research showed that people around the world must have evolved with emotions, because they all understand facial expressions of emotion without explanation. Emotions are a universal language that we have developed to communicate over time (Zimmer, C. 2008). This is why animals would need to express their emotions to those around them; primates in particular can be very social animals......middle of paper......role and some freedom. Unfortunately, the study's problems are just that: constraints on the number of physical and emotional descriptors do not allow a person to describe the whole experience, just a sample of it. The sample size is also lacking, and the fact that the sample came from such a small population also affects the validity of the results. The experiment was also carried out only with negative emotions and not with positive emotions. In conclusion, the study applies critical insights into the relationship between physiological and emotional responses during a stressful incident, but can still be improved. Works Cited Zimmer, C.
