Relationship between emotion gender is most part in its discovery yet. Psychologists are revising the question statement to "Who is more emotional within context X?" from "Who is more emotional?".
Thus there's no much example for this topic, but one interesting story here. In 1996 the U.S. Supreme Court ruled on a case concerning the Virginia Military Institute (VMI), where only men were admitted to enter. In the court case where women were asking for admittance, men refused becuase "Compared with men, women are more emotional, less aggressive, suffer more from fear of failure, and cannot withstand stress as well" (Greenberger&Blake, 1996).
Emotion and Culture
One of the examples regarding emotion and culture is that in some cultures, people attending funeral has to show extreme grief to show the magnitude of their love to the person deceased. But in some cultures, people should feign stoic and show no extreme grief, since it may worsen the gloomy atmosphere.
Another example is the difference between emotion in chronic war-time region and peaceful region. People who are living in a place where the war has continued for decades or centuries might not feel frighten of sounds of gunshot or bombarding, because they are all accustomed to the sounds. In contrast, people living in peaceful area will be terrified when they hear a single gunshot.
