 Among the many profiles that are theoretically possible in this system, are the familiar profile of the person with explosive anger, profile of the person with repressive anger, profile of the passive aggressive person, and the profile of constructive anger expression.Much research has explored whether the emotion of anger is experienced and expressed differently depending on the culture.Matsumoto (2007) conducted a study in which White-American and Asian participants needed to express the emotions from a program called JACFEE (Japanese and Caucasian Facial Expression of Emotion) in order to determine whether Caucasian observers noticed any differences in expression of participants of a different nationality.
