In the Past negative emotions would have been expressed in a much different way to how they are expressed now, and would have been triggered by different things. In the older times gestures and physical movements would have been the normal way to express their feelings, rather than now days when language and conversation is used. The emotions were expressed in these ways to let other people know that they have triggered negative emotions in someone, but also to try and share the pain and frustration these emotions bring on with other people.
Anger: In the past anger would have been expressed in much more physical means than it is today, and normally would have been provoked easier, with less understanding of how humans behave, and less communication skills to aid the prevention of it. Violence would be used to show that someone has done something wrong and brought on anger into someone, it also makes sure that the person is trying to channel their feelings into others, and make them feel equally as negative. In past times, words were rarely used, and as a result, the expression of anger was usually vague, hence hard to revert.
Fear: It is very hard to pinpoint exactly how people express their emotion of fear, as it may be caused by a countless amount of things, that usually the person is uncomfortable with, a new experience, or something with very risky outcomes as examples. Expressing fear is usually done by rejection and denial to do or confront the thing that is provoking the fear inside someone. Now and in the past, the expression of fear is trying to do the opposite of what brings on the emotion, so that the emotion is erased altogether. The expression of this emotion is also a way to counter the emotion itself, and make it disappear.
Sadness: Sadness in the past would have also been expressed with denial and segregation from the people or thing that caused this emotion. It is usually caused by something you do not want to do, or may be caused by something that went wrong, whether it is in love and friendship or in school or work. In the past expressing sadness would have been very drastic in proportion to the size of the event that provoked the emotion. Tears are a physical aspect that is usually associated with sadness, and is an easy way to determine how someone is feeling. Sadness was in the past expressed like this, as it was a way to let feelings out, and show people how they felt, so that they would get sympathy, but also so that people may offer them a solution to what was causing this emotion.
Negative emotions in the older times, were usually expressed with negative actions, due to negative occurrences which provoked these emotions.
